Small Island Perspective
The document discusses the impacts of climate change on oceans and cryosphere (ice) as outlined in the IPCC's Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). It notes that sea level rise will continue beyond 2100 and could reach 1 meter by 2300 under low emissions scenarios but up to 5.4 meters under high emissions. Adaptation will be necessary to address sea level rise impacts, with low emissions giving the best chance of successful adaptation. The document emphasizes that every fraction of a degree of warming, every year of action or inaction, and every mitigation or adaptation action matters to address the threats of climate change on oceans, coasts, and low-lying islands.
Water Systems and security
The document summarizes key findings from the IPCC's Special Report on the Ocean and Cryosphere in a Changing Climate. It finds that glaciers and snow cover are declining rapidly around the world, including in regions like Europe, Africa, South America and Asia. This is increasing hazards like floods and landslides. Peak water levels in glacier-fed rivers have already passed or will pass by mid-century in many areas. This will significantly impact downstream water supply for billions of people. Adaptation measures are needed to help communities adjust and ensure sustainable water resources in a warming world. Limiting warming to 1.5C compared to 2C could help reduce these risks.

Climate Change & Anthropogenic Impact On Water Resources
Human activities are clearly influencing the climate system and causing changes that are affecting water resources in several ways. According to the IPCC, over half of the increase in surface temperatures since the 1950s is due to human greenhouse gas emissions. As the climate continues to warm, precipitation patterns are projected to change in ways that will impact water availability and quality. Infrastructure like dams and reservoirs has altered water flows, and building more could help address issues like declining storage capacity but also risks impacts on environmental flows. Managing these tradeoffs between human and environmental water needs is an ongoing challenge.
Climate Change Effects on Water
This document summarizes the observed and potential future impacts of climate change on water resources at Hubbard Brook Experimental Forest based on long-term data collection and climate modeling. Key findings include increases in annual precipitation, more frequent high flow events, decreases in snowpack, earlier snowmelt and soil thaw, rising stream temperatures, and potential impacts to water quality. These changes may have consequences for forest management, infrastructure, and recreation that require consideration of climate adaptation strategies.
Sea Level Rise
Sea levels are rising due to global warming caused by human emissions of greenhouse gases. The two main causes of sea level rise are the thermal expansion of ocean water as it warms and the melting of land ice sheets and glaciers. Current estimates show sea levels rising 3.2 mm per year globally but faster in some areas, threatening coastal communities with problems like flooding and erosion. To mitigate further dangerous sea level rise, experts recommend reducing greenhouse gas emissions by 80% by 2050, though even that may only limit warming to 4-6 degrees Celsius by 2100.
Climate change presentation.
Climate change is a change in global weather patterns caused largely by increased carbon dioxide from fossil fuel use. It is affecting the entire planet, causing temperatures to rise about 1.5 degrees Fahrenheit in the past century. This warming causes issues like droughts, species extinction from heat, and rising sea levels that threaten low-lying countries like the Maldives, which could be completely submerged since most of its land is only 5 feet above sea level. Potential solutions include reducing the use of fossil fuels and carbon dioxide emissions as well as choosing alternatives to driving like walking or biking.
Calentamiento global
Global warming is caused by carbon dioxide from human sources like vehicles and factories trapping heat in the atmosphere, similar to the greenhouse effect. This is causing ice caps and glaciers to melt, which raises sea levels and could flood coastal areas. Rising global temperatures are also expected to alter forests and crop yields, spread diseases, and damage ecosystems and national parks. The rapid warming of the past 150 years is unprecedented and is largely due to increased fossil fuel usage. This warming is damaging coral reefs and causing penguin populations to decline. Reducing fossil fuel use would help minimize further global warming impacts.

Impacts and risks for global marine biodiversity and fisheries
Elvira Poloczanska - Risks to Ecosystems and Human Systems from Changes in the Ocean and Cryosphere
Change Agents (MCISUR 2012)
This document discusses several impacts of climate change from an oceanographic perspective, including ocean warming, sea level rise, and ocean acidification. It notes that these issues are worldwide in scope and linked to increasing CO2 levels. Specific impacts highlighted include more intense hurricanes, rising seas threatening coastal populations like in Bangladesh and the Maldives, and harm to coral reefs and other organisms from acidification. The human impacts discussed include increased environmental refugees, effects on health, and the potential for conflict. The document raises the possibility of approaching a tipping point and examines geoengineering as a potential remedy for climate change, but notes the risks of such large-scale intervention.

Sea-level rise and Extreme Sea Level Events
This document discusses projections for sea level rise and extreme sea level events from climate change. It notes that Antarctic ice sheet contributions to sea level rise were revised upwards in recent reports. Without sharp reductions in emissions, sea level rise may exceed 1 meter by 2100 and extreme sea level events could become at least 100 times more frequent at most coastal locations before 2100. The document also warns that many tropical islands and low-lying cities will face annual flood risks by 2050 under any emissions scenario without strong adaptation efforts, and sea levels could rise up to 5 meters by 2300 if emissions are not cut.
Climate Change Impacts on Hydrology and Water Quality
Randy Lehr (Northland College), presented at the Adapting Forested Watersheds to Climate Change Workshop, at The Waters, Minocqua, WI on March 15-16, 2017. The workshop was hosted by the Northern Institute of Applied Climate Science (NIACS), USDA Climate Hubs, and the Wisconsin Initiative on Climate Change Impacts (WICCI).
Global Warming
Global warming occurs when greenhouse gases like carbon dioxide trap heat from the sun in the lower atmosphere. Normally, the sun's heat would be reflected back into space, but greenhouse gases reflect it back to Earth, causing temperatures to rise. The effects of global warming include climate change, rising sea levels from melting glaciers, more extreme weather like floods and droughts, and threats to plants and animals. Current impacts include rising sea levels threatening islands, glacial retreat of 10-15cm per year in the Himalayas, and record forest fires in 2003 in Russia, America, and Portugal due to heat and drought. Solutions proposed include transitioning to renewable energy, promoting energy efficiency, and increasing carbon absorption through afforestation.
Impact of climate change on groundwater
CLIMATE change affects the components of water cycle such as evaporation, precipitation and evapotranspiration and thus results in large-scale alteration in water present in glaciers, rivers, lakes, oceans, etc. The effects of cli-mate change on subsurface water relates to the changes in its recharge and discharge rates plus changes in quantity and quality of water in aquifers. Climate change refers to the long-term changes in the components of climate such as temperature, precipitation, evapotranspiration, etc. The major cause of climate change is the rising level of greenhouse gases (GHGs) in the atmosphere such as CO2, CH4, N2O, water vapour, ozone and chlorofluorocarbon. These GHGs absorb 95% of the longwave back radiations emitted from the surface, thus making the Earth warmer. Except CO2, the effects of other GHGs are minor because of their low concentration and also because of low residence times (e.g. water vapour and methane). The rise in CO2 level causing global warming was first proposed by Svante Arrhenius, a Swedish scientist in 1896 and now it is a widely accepted fact that the concentration of CO2 is the primary regulator of temperature on the Earth and leads to global warming.
Climate change
Climate change is defined as the change in average weather conditions, including rising global temperatures caused by increased levels of carbon dioxide and other gases trapping heat in the atmosphere. If left unaddressed, climate change will have widespread effects like rising sea levels, more extreme weather, shifting seasons, and threats to both wildlife and agriculture due to warmer temperatures and ocean acidification. Individual actions like reducing greenhouse gas emissions by walking or biking more, supporting clean energy initiatives, and preventing pollution can help address the climate change problem caused by human activities.
Sea level rise (final)
Sea levels are rising due to multiple factors related to climate change. Thermal expansion caused by warming oceans, melting glaciers and ice sheets, and land ice loss from Greenland and Antarctica are leading to higher sea levels. This poses risks like coastal flooding, erosion, habitat loss, and saline intrusion. Adaptation strategies include protecting coasts through barriers, accommodating the rise through elevated structures, retreating to safer areas, and attacking the problem through land reclamation. Reducing carbon emissions to mitigate further global warming is key to reducing future sea level increases.
Climate change: changes in the cryosphere
The document discusses changes occurring in the cryosphere (frozen parts of the Earth's surface) including polar ice sheets, glaciers, sea ice and permafrost. It provides details on factors contributing to melting and decline of ice sheets in Greenland and Antarctica, such as rising air and ocean temperatures, increased surface meltwater, glacier acceleration and ice shelf instability. Graphs and maps show decreasing trends in Arctic sea ice extent, thickness and concentration over recent decades, as well as rising ice loss from both the Greenland and Antarctic ice sheets.

The Ocean and Cryosphere in a Changing Climate
The document summarizes key findings from the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate. It finds that the ocean and cryosphere have absorbed much of the increased heat from climate change, with consequences including sea level rise, shrinking glaciers and ice sheets, and changes in marine life. These changes threaten coastal communities, water resources, and cultural heritage. Urgent action is needed to address these impacts and transition societies in a sustainable way. Limiting warming to 1.5C would help societies better adapt to inevitable changes.
L spina climch-evidence
Climate change refers to significant and lasting changes in weather patterns over long periods of time. It is caused by both natural factors and human activities like burning fossil fuels which release greenhouse gases. Evidence of climate change includes rising global temperatures, shrinking glaciers, earlier flowering times, more extreme weather events, rising sea levels, and warming oceans. If emissions continue, the IPCC predicts increases in global temperatures between 1-3 degrees Celsius which will have both beneficial and harmful effects worldwide.
Climate change & its impact on our water resources_ Schools India Water Porta...
Climate change is causing changes around the world like receding glaciers and ice shelves. Greenhouse gas levels in the atmosphere are rising and causing the Earth's temperature to increase. Burning fossil fuels for energy and transportation, deforestation, agriculture, and waste are major contributors to increasing greenhouse gases. Rising global temperatures will lead to changes in precipitation patterns, sea level rise, and more extreme weather that threaten water resources and could displace millions of people. Solutions include transitioning to renewable energy, green buildings, afforestation, water conservation, and spreading awareness.
Federico_clim_ch-evidence
This document discusses climate change and its causes, effects, and potential solutions. It defines climate change as a significant change in weather patterns over long periods of time caused by both natural factors and human activities like burning fossil fuels. These activities have increased greenhouse gas emissions, trapping heat and causing global warming. Effects of climate change include rising sea levels, more extreme weather, and threats to ecosystems. Addressing climate change requires global cooperation to reduce emissions through alternatives to fossil fuels and sustainable development.
Landslides Presentation , it's causes, it's Effects,it's mitigation
Landslides refer to the movement of rocks, debris or earth down a slope under the influence of gravity. They are classified into four main types: falls, topples, slides, and spreads. Landslides are often caused by heavy rain, deforestation, earthquakes, volcanic eruptions, construction projects, shifting agriculture, and development. The effects of landslides can be both short-term, such as loss of life, property damage and blocked roads/rivers, and long-term, including permanent landscape changes, loss of farmland, erosion and population migration. Prevention methods include hazard mapping, restricting development in at-risk areas, afforestation, early warning systems and disaster response preparedness.
Class 5, Megadrought i
Throughout history, drought is constant threat to societies around the world. What do proxy records tell us about the severity, extent and causes of drought during the last thousand years?
Class 7, Megadroughts II
The document discusses the Medieval Warm Period between approximately 900-1300 AD. It provides evidence from historical records of warmer conditions in parts of the world during this period compared to later centuries. Climate data from central England and temperatures in Europe are discussed. While some regions like China were cooler, other areas like South Japan and Western Europe experienced warmer temperatures during this time compared to after 1300 AD, known as the Medieval Climate Optimum. There is debate around the extent and causes of warming, with more evidence needed to fully understand natural variability compared to potential human influences on climate.

GEOG3839.14, The West, water and the Colorado River
This document summarizes research on surface temperature reconstructions over the past 2,000 years and tree-ring analysis of droughts in the American Southwest. Tree rings have been used to reconstruct Colorado River flows over the past 1,200 years, showing megadroughts more severe than any in the 20th century. This long-term context challenged water management assumptions and highlighted the potential for even worse droughts under climate change.
IonE Frontiers, Through The Trees
Many of the decisions we make about environmental issues are based on experience. Whether we're setting limits for the use of scarce resources, estimating the risks posed by natural hazards, or deciding how to manage protected areas, our plans for the future often reflect our understanding of the past. The problem is that, when it comes to the environment, our society has a fairly short memory. In this presentation, Dr. St. George will discuss how the study of ancient trees is expanding our perspective on the natural history of the northern Plains and helping to answer questions about what the future may hold for Minnesota's environment.
GEOG3839.23, Frontiers in dendrochronology
This document discusses advances in the field of dendrochronology. It describes new modeling approaches that use tree ring data to better understand climate variability over time. These include the Vaganov-Shashkin model that tracks limiting growth factors throughout the growing season. Stable isotope analysis of tree rings is expanding the field into the tropics by allowing the reconstruction of climate variables without visually distinct annual growth rings. Overall, tree ring data combined with new statistical techniques and modeling are improving scientists' ability to study past climate changes and validate climate reconstructions.
Guarding against false discovery in large-scale dendroclimatology
Measurements of tree-ring widths are the most widely-distributed and best replicated source of surrogate environmental information on the planet, and are one of the main archives used to estimate changes in regional and global climate during the past several centuries or millennia. Because the Northern Hemisphere ring-width network is now so large, it is more crucial than ever to ensure our understanding of tree-environment relations is not influenced by decisions to include or exclude certain records. It may be the case that a particular set of ring-width records are, for whatever reason, more tightly coupled to a particular climate factor than other records from the same region or species and, as a result, may be superior estimators of that factor’s past behavior. At the same time, it is known that selecting a small number of predictors from a large pool of potential candidates increases the likelihood of a Type I error. That effect may be particularly relevant to dendroclimatology because the total number of available ring-width records is often much larger than the number of records used to produce reconstructions of large-scale climate features. As an initial step, it would be helpful if paleoclimate reconstructions derived from tree rings described more explicitly the criteria used to select ring-width records as potential predictors and specified those records excluded by that screening. By comparing ring-width chronologies and their relations with climate against the standard set by thousands of records across the hemisphere, we should be better able to distinguish climate signals from proxy noise and produce more accurate reconstructions of climate during the late Holocene.

The document discusses how paleoclimatology provides insights into past climate changes in Canada by studying ice cores, tree rings, fossils, and geological features. It highlights research using these methods to study glacial retreat after the last ice age, changes in Great Lakes water levels, Arctic sea ice extent over the past 10,000 years, and sensitivity of the Greenland Ice Sheet. Paleoclimatology gives scientists a longer-term view to understand climate impacts and improve climate models.

They are also evaluating the impacts of increased meltwater on water quantity and quality through hydrochemical measurements and models. Additionally, they are assessing community adaptation and household changes through selected case studies and community interviews. Preliminary results show glaciers are losing 0.61% of their area annually on average, with rates doubling in some locations. This is transforming seasonal water flows and increasing concerns over water quality and supply.
GEOG5839.21, The Colorado River
Tree rings have been used to reconstruct streamflow in the Colorado River basin over centuries. This revealed that severe multi-year droughts were more common than shown in the instrumental record. A 1,000-year drought reconstruction for western North America also indicated droughts could last decades. Tree rings have additionally helped develop the North American Drought Atlas which provides drought context for historical events and shows Asian monsoon variability over centuries.

The document discusses the threat of sea level rise from the potential collapse of the West Antarctic ice sheet due to climate change. It summarizes the history of scientific understanding on this issue, from early warnings in the 1970s to recent evidence that glaciers and ice sheets are melting faster than predicted and contributing over 1 mm/year of sea level rise. The collapse of the West Antarctic ice sheet could lead to over 5 meters of rapid sea level rise and has the potential to significantly impact coastal regions where over a billion people live. Quick action is needed to mitigate the effects of human-caused climate change and sea level rise.
Prof Alan Rodger - The Latest Evidence on Climate Change, Beyond IPCC
This document discusses the impacts of climate change beyond what is captured by the IPCC reports. It summarizes findings from ice core research showing atmospheric CO2 levels are now higher than the past 650,000 years. Sea level rise and temperature rise are accelerating due to human emissions. Extreme weather events are becoming more frequent and intense. Uncertainties remain around future climate impacts due to natural variability and incomplete models. Non-linear effects could lead to unexpected changes.
Why the past matters - how tree rings and environmental history help us make ...
This document discusses how studying tree rings and environmental history can help with managing resources and risks related to water and climate. It provides three key points:
1) Tree rings and other climate proxies like lake sediments and ice cores provide information about past climate variability like droughts, floods, and shifts in atmospheric patterns over centuries. This helps understand the range of natural climate variations.
2) Reconstructions of past river flows and floods indicate that some past events were more extreme than what modern records show, challenging assumptions about water availability and flood risks. This provides "stress tests" for water resource systems.
3) Decadal-scale climate patterns like the Pacific Decadal Oscillation cause important swings in precipitation
Nature Nights: A Low-to-No Snow Future
Mountain snowpacks have historically acted as large, natural reservoirs of water, as well as providing awesome recreational opportunities. In recent decades, however, snowpack has declined—another sign of a changing climate. If our climate continues to warm, snow loss will be exacerbated across the Western US, termed a “low-to-no snow future.” Join the Deschutes Land Trust, Dr. Alan Rhoades, and Dr. Erica Siirila-Woodburn to learn about the possibility of a low-to-no snow future in the Cascades. Dr. Rhoades and Dr. Siirila-Woodburn will offer proactive solutions to both mitigate the extent of and adapt to the changing conditions of a low-to-no snow future. Learn how you can help make a difference in our (hopefully!) snowy future.

Climate Change: The Evidence and Our Options
This document summarizes the research of the Ice Core Paleoclimate Research Group at Ohio State University. The group studies ice cores from around the world to understand past climate changes. It receives funding from various organizations. Ice cores provide evidence that some glaciers are currently smaller than they have been in the past 6,000 years and that recent warming is unprecedented over the last 1,000 years. The document discusses both natural and human factors that influence the climate and presents evidence that recent warming is not caused by changes in the sun's output but rather by increasing greenhouse gases from human activities.
GEOG5426: Class 1, Course introduction
How has our climate changed in the past? What caused those changes, and can understanding the Earth’s climate history help us better predict the future? Does the past really matter?
In this seminar course, we will examine these questions through the lens of paleoclimatology, which uses physical and cultural evidence to make inferences about climates of the past. We will review the processes that govern our modern climate and explore what paleoclimate records tell us about how these systems respond to (and express) climate change.
Climate change
Climate change is caused by both natural factors like changes in the sun's output as well as human activities that increase greenhouse gases. We know the climate is changing due to measurements of rising global temperatures and sea levels as well as observational records like ice cores. If greenhouse gases continue to increase, the impacts of climate change are projected to intensify and include more extreme weather, rising sea levels, and effects on human health, water resources, agriculture and forests. Individual actions as well as technological solutions will be needed to reduce emissions and mitigate the effects of climate change.
Sea level rise, emerging issues paper, royal society of new zealand, sept 2010
Sea levels are rising due to global warming. In the past when the Earth was warmer, sea levels were several meters higher. Recent scientific studies project greater sea level rise than previous IPCC reports, ranging from 0.5 to over 1 meter by 2100. Uncertainty remains about how quickly polar ice sheets will melt and increase sea level rise. Thermal expansion of oceans as they warm also contributes to rising sea levels. Local risks may be increased in some areas depending on tectonic movements of the land.
Climate Change
Over the last decade, climate change has accelerated the melting of Antarctic ice sheets and Arctic glaciers faster than predicted. The Arctic ice cap reached a record low in 2007 and climate models predict the region could be ice-free in summer within the next decade. An ice-free Arctic could impact weather patterns in the Northern Hemisphere and threaten polar bears that rely on sea ice. Climate change is also apparent through a decade-long drought in Australia, shifting plant life in the Rocky Mountains, and earlier snowmelt affecting plant competition. Melting ice, droughts, and earlier springs in addition to disappearing species show global warming is affecting the planet.

Boosting the Signal: Simple Strategies to Deliver Better Scientific Talks
A good talk can open the doors to new collaborations, increase your chances of funding success, and make it more likely other people will respond to your ideas. But scientific presentations are too often confusing, boring, and overstuffed. Here are some suggestions, based on our experience as speakers, audience members, and presentation trainers, that we hope will make your next conference talk or seminar more enjoyable, engaging and effective.
Ringing true: The scientific and societal relevance of dendrochronology at th...
Tree rings and other natural archives empower us to extend our perspective on environmental change, resources, and hazards. But many contemporary applications of paleoclimatology and paleohydrology are useful because of the lasting disruption to our collective environmental memory caused by colonization.
How long do trees remember?
Much of what we know regarding variations in Earth's climate during the past millennium comes from tree rings. But tree rings, like other proxies, attenuate some climate signals but amplify others, and their fidelity at longer timescales is difficult to gage. Even though dendroclimatology is well-established, questions remain about the climate clues encoded in tree rings — particularly at decadal-to-centennial timescales.
Don’t call it a comeback: Studying ancient floods to prepare for future hazards
How long do we need to watch a river before its behavior holds no more surprises? In this country, instrumental measurements of river stage and discharge stretch back a century or more, but this observed history still provides only a rough guide to the risks of future extreme floods. In this lecture, I’ll outline how paleoflood hydrology expands our perspective on river history by combining historical, botanical, and geological evidence of earlier (and ofttimes unknown) floods. And I’ll explain how we can interpret those physical clues left behind by ancient floods to improve hazard assessments for at-risk communities, support decisions about flood infrastructure, and investigate the long-term effects of climate or land-use changes on flooding. Because what has happened before can happen again, most everyone near a river would profit by keeping a longer memory of old floods.
Flood rings: Paleoflood evidence in tree-ring anatomy
In low-gradient, low energy rivers, forms of tree-ring evidence such as impact scars or stem deformation do not provide useful evidence of past floods. In this talk, I explain the strengths and limitations of wood anatomy as tools in in paleoflood hydrology.
Historic accounts of extreme floods on the Red River of the North
Here I explain how Canadian and American communities along the Red River of the North have developed fundamentally different responses to the threat of flooding, and argue that these differences in flood mitigation reflect disparate experiences with particular floods during the past two hundred years.
Disentangling the decadal ‘knot’ in high-resolution paleoclimatology
Even after more than a century of coordinated monitoring, instrumental weather observations are still too short to adequately constrain decadal or multidecadal behavior in the Earth’s climate system. Leading climatologists and climate modelers have called for the wider application of high-resolution proxy records to decadal variability and prediction studies, and our community has responded by producing new paleoclimate products that specifically target this type of ‘intermediate-term’ behavior. But we now also know our medium changes that message: the biological and geological systems that encode climate information into natural archives often also alter the original ‘input’, usually due to either seasonal filtering or non-climatic persistence. In this talk, we’ll discuss some of the challenges inherent to the use of high-resolution proxies to study decadal or multi-decadal climate variability, and suggest strategies that might clarify how climate acts on those timescales. And we’ll also present a new theoretical framework that could help paleo-scientists evaluate competing ideas about the causes of decadal- or multi-decadal events known to have occurred during the past one or two millennia.
A new framework to test the origins of western American megadrought
We know from tree rings and other natural drought records that the western United States has been affected by several 'megadroughts' during the past millennium. But are these exceptionally long-lasting droughts due to unusual external forcings, or are they inevitable given a sufficiently long period of time? Here we present a statistical model that combines sea surface temperature records and drought severity statistics from the western USA, and use that tool to set out an expectation for megadrought, given no other changes in the climate system. Even though this model was trained using only modern climate data (and incorporates no information from tree rings or other proxies), it still produced megadroughts. Moreover, those simulated megadroughts were just as long-lasting, covered as large an area, and were just as severe as real megadroughts estimated from tree rings. That result means that megadroughts can occur in the western United States even if nothing else changes in the climate -- they really are just a matter of time. On the other hand, the only aspect of real-world megadroughts that the model cannot duplicate was the high number of these events during the so-called Medieval Climate Anomaly (800 to 1300 CE). So that cluster of megadroughts may have been caused by some sort of unusual climate circumstances that have not been observed by us during the past few decades. The proxy record tells us that many different kinds of exceptional or unusual climate events happened in the past. But it is often difficult to determine what caused those exceptional events because even, within a period of a thousand years, we still have very few cases. So besides being an aid to understand the causes of past megadroughts, we hope this approach can be applied to other paleoclimate records to distinguish between real interrelations between separate components of the climate system and simple coincidences.
The need for new theory in global dendroclimatology
This document summarizes an interdisciplinary tree-ring research conference. It discusses the need for new theory in dendroclimatology, presentations on temperature and river flow reconstructions from tree rings, and principles of tree ring research site selection and replication. It also questions how to evaluate rare signals in tree growth and climate relationships and where remote teleconnections may be most evident in tree rings.
The societal value of historical and paleoflood research in Manitoba, Canada
1) Shared knowledge of past natural disasters has a major impact on preparation for future hazards. The document discusses the historical floods along the Red River in Manitoba, Canada.
2) Winnipeg built a large flood diversion channel in the 1960s after experiencing major floods, including in 1826 and 1950, to protect the city from future flooding of the Red River.
3) American communities like Grand Forks and Fargo were more vulnerable to Red River flooding until recently because they did not have the same long historical memory of floods that informed Winnipeg's early investment in flood protection infrastructure.
Solar ghosts: Weighing the evidence for sunspot cycles in fossil trees
In their study of tree rings from the Chemnitz Fossil Forest (Germany), Luthardt and Rößler (2017) claim to identify a regular near-11-yr cyclicity in growth, and present that pattern as evidence of the influence of the Schwabe solar cycle (Usokin and Mursula, 2003) on climate and forest productivity during the early Permian. If correctly interpreted, these fossil tree rings would indicate the sunspot cycle was the dominant influence on interannual variability in Earth’s climate during this period and that it has been a consistent aspect of our Sun’s behavior for at least the past 300 m.y. We argue the fossil tree-ring record from Chemnitz does not constitute reliable evidence of solar activity during the Permian because the individual tree-ring sequences are not correctly aligned (dendrochronologically dated) and, as a result, the mean ring-width composite is not a meaningful estimate of year-to-year variations in tree growth in this ancient forest.
Long droughts: Using natural climate archives to gage the risks of future “me...
In the Biblical story of Joseph, following seven years of abundance, the Kingdom of Egypt was confronted by seven years of drought and famine. In the parlance of modern climate science, intervals with several consecutive extremely dry years are described as ‘“megadroughts”. In this short talk, I’ll describe how climate scientists combine clues from natural weather archives (including corals, tree rings, lake sediments, and many other sources) to reveal the history of ancient megadroughts across our planet. And I’ll highlight new research that combines these surrogate drought records with simulations from state-of-the-art climate models to help us better anticipate the risks of unusually persistent droughts during the coming century.
Expecting the unexpected: The relevance of old floods to modern hydrology
This document discusses the importance of understanding past floods to properly assess modern flood risks. It provides examples of paleoflood research along rivers like the Red River of the North, which uncovered major floods in 1826 and around 700 years ago that exceeded any floods measured by modern instrumentation. Understanding a river's full history through both recorded data and geological evidence of past floods is essential for floodplain management, development planning, and infrastructure design to mitigate future flood risks.

Climate simulations were run for 1000 years, with 1000 total simulations conducted. The simulations modeled climate changes over long time periods. The large number of long-term simulations provided insights into potential climate variations and outcomes.
Decadal variability in tree rings
Strong variance at decadal and multidecadal timescales is a common feature of most tree-ring width records. But does this aspect of tree growth exhibit such long-memory behavior due to biology, climate, or some combination of the two factors? Understanding the origins of this behavior is crucial for efforts to evaluate the causes of decadal variability in the climate system.

Trees as flood sensors
In many settings, trees growing on floodplains provide an important source of indirect evidence that may be used to infer the occurrence, extent, and magnitude of floods prior to direct observations. That evidence may take several forms, including external scars caused by abrasion or impact from floating debris, anatomical changes within the annual growth increment following prolonged stem or root inundation, or tilting or uprooting due to the hydraulic pressure of floodwaters. Likely the most useful characteristic of paleoflood studies based on floodplain trees is their relatively high temporal resolution and dating accuracy compared to most other methods. Dendrochronological methods can routinely date past floods to the year of their occurrence and, in rare cases, can estimate the timing of floods that occur during the growing season to within two weeks. This high degree of chronological control, which is surpassed only by that provided by direct observation or instrumentation, can be used to determine whether floods in separate watersheds were synchronous or offset by several years and test hypotheses that suppose linkages between extreme floods and specific forcing mechanisms. Furthermore, the wide geographic distribution of tree species with dateable rings combined with the broad suite of methods available to examine interconnections between floods and tree growth allow this style of paleoflood hydrology to be applied to many settings that are not suitable for techniques that depend on geological evidence. Future paleoflood research involving tree rings will need to strike a balance between improving our understanding of the biological and fluvial processes that link tree growth to past events, and providing answers to questions about flood dynamics and hazards that are needed to safeguard people and property from future floods.
Expanding the window - the past, present, and future of Minnesota's water
Nearly all decisions about water in Minnesota relate either directly or indirectly to data collected by the state’s hydrological observing network. Because most gauges were installed in early 20th century, as a whole the network provides us with roughly a 100-year ‘window’ to estimate flood risks, develop worst-case scenarios for drought, and set maximum allowable withdrawals for aquifers. But when we rely exclusively on observations made during this relatively brief interval, we may inadvertently increase our exposure to hydrological ‘surprises’. In order to make sound decisions about water in Minnesota, we need to expand this window: into the past, drawing upon historical accounts and natural archives; and into the future, via projections from climate and hydrological models. By cultivating a broader perspective on hydrological variability and extremes across the state, we will be better prepared to ensure adequate water supplies and mitigate the impacts of future floods and droughts.
Making Climate Data Sing
These visuals were prepared to support a string quartet performance and panel on climate change at Northwestern University in February 2106.
A well-designed graphic can help audiences to quickly understand the main message embedded within a complex set of climate data and to retain those ideas longer than they would have if they were conveyed by words alone. But the visual aids used regularly by climate scientists also have their limitations: they are most easily understood by people who are already fluent in technical illustrations; they're usually static and sometimes do not tell an obvious story; and for many, they don't elicit a strong emotional response.
Music, by contrast, is inherently narrative and is known to exert a powerful influence on human emotions. Because of this, sonification — the transformation of data into acoustic signals — may have considerable promise as a tool to enhance the communication of climate science.
Daniel Crawford and Scott St. George report on a collaboration between scientists and artists that uses music to transmit the evidence of climate change in an engaging and visceral way.
Large-scale dendrochronology and low-frequency climate variability
Large-scale low-frequency variability has emerged as a priority for climate research, but instrumental observations are not long enough to characterize this behavior or gage its impacts on dependent geophysical or ecological systems. As the leading source of high-resolution paleoclimate information in the middle- and high-latitudes, tree rings are essential to understand low-frequency variability prior to the instrumental period. But even though tree rings possess several advantages as climate proxies, like other natural archives they also have their own particular impediments. In this lecture, Dr. St. George will describe the structure and characteristics of the Northern Hemisphere tree-ring width network, and outline how the fingerprint of decadal and multidecadal climate variability encoded within ancient trees varies across the hemisphere.

GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.Leveraging the Graph for Clinical Trials and Standards

Digital Banking in the Cloud: How Citizens Bank Unlocked Their Mainframe
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
