Climate Change in the Arctic

Zachary Labe

The document discusses climate change in the Arctic. It notes that the Arctic is warming faster than the rest of the globe, with sea ice extent and thickness declining significantly. Climate models project that Arctic warming and sea ice loss will continue through the 21st century. Improving observations and models can help reduce uncertainties about future climate impacts in the Arctic and how changes may influence remote weather patterns. Action is needed to reduce emissions and limit global temperature rise in order to prevent the worst effects of climate change in the Arctic.

Contrasting polar climate change in the past, present, and future

Keith_Shotbolt

This document summarizes projections of future Arctic climate from the research of Zachary Labe. Sea ice extent is declining at a rate of 0.8 million km2 per decade as Arctic temperatures rise more than twice as fast as the global average. This warming amplifies in the Arctic (Arctic amplification) and is influencing weather patterns in northern mid-latitudes. Research indicates that continued sea ice loss will cause significant warming over the Arctic Ocean and a shift in the jet stream, with impacts on weather extremes. Understanding Arctic climate variability is important for assessing future local and remote responses to changes in the region.

Researching and Communicating Our Changing Climate

Zachary Labe

Zachary Labe is a postdoc researcher at NOAA GFDL and Princeton University who studies climate variability and change. His research uses tools like artificial intelligence and climate models to disentangle the signal of climate change from natural weather noise. He conducts field work including Arctic expeditions and uses supercomputers to run complex climate models that generate huge amounts of data.

Anthropomorphic, climate change

nybergjohn

Global warming is part of natural climate cycles according to the document. It argues that the Earth's climate is primarily influenced by solar activity and fluctuations in the sun's irradiance. The document provides several lines of evidence from historical temperature and greenhouse gas records, as well as studies on plankton and agriculture, to support its view that global warming poses no significant risks and may provide economic benefits from increased growing seasons and rainfall. However, it does not consider the potential long-term consequences of rising sea levels or more severe storms.

Rising Seas & Solutions

Paul H. Carr

The year 2014 tied with 2010 as the warmest year on record for the last century. The melting of Greenland, mountain glaciers, and thermal expansion is raising sea levels four times faster than in 1900. Sea level rises of 2 to 6 feet are predicted by the end of the century. Flood highs from hurricanes Sandy and Katrina were ~ 10 feet. The article “Treading Water” in the February 2015 "National Geographic" tells how Dutch Docklands LLC sees profit not loss from rising sea levels. They are building floating homes in Miami, FL. A floating classroom could assure ASPEC’s long-term future. It would provide a place to meet in the event of flooding by the 10-foot ocean surges that accompany hurricanes. Dr. Carr describes how increasing greenhouse gases, mostly carbon dioxide from the burning of fossil fuels, trap the radiation that is warming our planet. Advances in non-carbon emitting energy sources can reduce global warming. Solar PV panels are now generating electricity at $0.07/kWhr, less than the national utility average of $0.12kWhr. Rising sea levels are a better measure of global warming than atmospheric temperature, as 90% of our planet’s heat content is in our oceans. You can learn more at www.RiskyBusiness.org.

What are we doing to our climate? What is it doing to us? What can we do?

Paul H. Carr

OVERVIEW I will be introducing you to ECONOMIC, ECOLOGICAL, and TECHNOLOGICAL ISSUES. ¥ Climate change is an unintended consequence of carbon dioxide emissions from burning fossil fuels. ¥ By pricing in the social and environmental cost of these emissions, we can expedite their reduction. Let’s harness profit greed towards green technology development. ¥ The environmental challenge is to balance the beauty and sacredness of nature with its utility. ABSTRACT What are we doing to our climate? The scientific consensus. Tides and temperatures are rising. Since the beginning of the industrial age, emissions from fossil fuel burning have raised carbon dioxide concentrations to 410 ppm. This is 33% higher than in the last million years. This increase is warming our planet via the Greenhouse Effect. At the present rate of carbon dioxide increase, we will reach 800 ppm by 2100. When our earth was at this concentration 40 million years ago, it was so warm that there was no ice. Sea levels were about 300 feet higher than today. What is climate change doing to us? “The earth and its poor cry out, and we must listen” Pope Francis. Dry regions are drier and wet ones wetter. Wildfires have increased threefold since 1970, storms more violent, floods setting record heights, and glaciers melting. Natural catastrophes are occurring more than twice as frequently as in 1980. Sea levels could rise as high as 18 feet by 2060. Parts of Earth are increasingly uninhabitable, resulting in millions of climate change refugees, CLIMmigration. What can we do? Religion and science matter. Ethics trumping economics. Let’s yoke our knowledge of climate science with the motivational power of spiritual values. We need to reduce our carbon footprints. We now have the option to purchase green electric cars getting the equivalent of 100 miles per gallon and solar PV panels to lower our electric bills. We can support the Citizen’s Climate Lobby which advocates a revenue neutral carbon production fee resulting in a dividend returned to all. This would stimulate our economy creating millions of jobs and increase the deployment of green solar, wind, and nuclear energy sources. Thorium, in addition to uranium, is a green energy source for the future. Republicans are less afraid of nuclear energy than Democrats.

Energy and the Polar Environment: A Focus on Middle School

The Ohio State University, College of Education and Human Ecology

The document summarizes resources for teaching middle school students about global warming and its effects on the polar regions. It defines key terms like albedo and describes how melting sea ice causes a positive feedback loop that warms the Arctic. It also outlines national science standards, common student misconceptions, and hands-on activities about topics like light reflection, the carbon cycle, and analyzing climate data and sea ice extent.

Alok Arunam

The document discusses the topic of climate change, past, present, and future. It provides an overview of the factors that control climate, including land surface properties, oceans, greenhouse gases, and solar radiation. It describes how the climate has varied in the past due to natural factors like variations in Earth's orbit and composition of the atmosphere. It then discusses evidence that warming trends over the last few decades are likely due to human activities like fossil fuel burning. Models predict that future climate change may have significant impacts.

TMN-COT

The document discusses several topics related to climate change, including natural climate oscillations, urban heat islands, land use changes, temperature proxy records, and measurements of land and ocean temperatures. It questions the reliability of some temperature proxy records and surface temperature measurements, and argues that climate models likely overestimate the warming effects of increased CO2 levels.

Climate Change - How We Know What We Know

Michael DeLapa

Global Climate Change

Georgian Court University

The document discusses global warming and its causes and impacts. It summarizes that carbon dioxide emissions from the burning of fossil fuels are trapping heat in the atmosphere and warming the planet. This is causing rising temperatures, more extreme weather, sea level rise, and other environmental changes that are damaging to human society and natural ecosystems. The document advocates for solutions like transitioning to renewable energy and green building practices to mitigate the problem.

Observations and climate model projections of Arctic climate change

Zachary Labe

The document summarizes observations of Arctic climate change and projections from climate models. It finds that the Arctic is warming twice as fast as the global average due to a process known as polar amplification. Satellite data shows sea ice extent and thickness have sharply declined in recent decades. Climate models project further sea ice loss and amplified warming in the Arctic under high emissions scenarios. This could impact weather patterns in mid-latitudes through changes to jet streams and storm tracks. Improved observations and modeling are needed to reduce uncertainty about future impacts.

Global climate change facts

DR VINAY KUMAR PANDEY

1) The document discusses various causes of global climate change including changes in Earth's orbit and solar radiation, albedo effects, and greenhouse gases like carbon dioxide and methane. 2) Evidence of past climate changes is seen in temperature and carbon dioxide variations from ice cores, glacial activity, sea levels, and vegetation changes. 3) The author argues that climate change is a natural phenomenon and that the role of human-caused carbon dioxide emissions in current warming is limited and uncertain.

Climate Change v 2012

Gordon M. Groat

The document discusses several factors related to climate change: 1. It discusses three primary factors that influence Earth's orbit and axial tilt - eccentricity, axial tilt, and precession - and how these Milankovitch cycles impact climate over long time periods. 2. It explains the Ruddiman hypothesis, which suggests that human agricultural activities beginning around 8,000 years ago prevented the onset of a natural ice age, and industrialization in the 19th century further disrupted the climate cycle. 3. It provides examples of how human activities like fossil fuel use, deforestation, and agriculture have increased greenhouse gases in the atmosphere like carbon dioxide and methane, driving unprecedented modern climate change.

Authoring a personal GPT for your research and practice: How we created the Q...

Leonel Morgado

Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

The cost of acquiring information by natural selection

Carl Bergstrom

This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome. It's based on the first part of this research paper: The cost of information acquisition by natural selection Ryan Seamus McGee, Olivia Kosterlitz, Artem Kaznatcheev, Benjamin Kerr, Carl T. Bergstrom bioRxiv 2022.07.02.498577; doi: https://doi.org/10.1101/2022.07.02.498577

ESR spectroscopy in liquid food and beverages.pptx

PRIYANKA PATEL

With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Immersive Learning That Works: Research Grounding and Paths Forward

Leonel Morgado

We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

The binding of cosmological structures by massless topological defects

Sérgio Sacani

Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is mitigated, at least in part.
