Oceans cover most of the Earth's surface and contain nearly all of its water. Sea levels are rising at about 10 times the rate over the past 3,000 years due to global warming, which is causing oceans to increase in size. Rising sea levels threaten coastal areas through increased erosion, flooding, and damage from storms. Scientists project that by 2100, sea levels could be 0.8 to 2 meters higher than current levels without action to address climate change.
Oceans cover most of the Earth's surface and contain nearly all of its water. Sea levels are rising at about 10 times the rate over the past 3,000 years due to global warming. As a result, coastal areas are experiencing problems like erosion and damage from higher tides and stronger storms. Scientists predict that by 2100, sea levels could be 0.8 to 2 meters higher than today if warming continues unabated.

The document discusses mudflows, also known as lahars or debris flows. It defines mudflows as rapid movements of debris containing large amounts of water that mix with rock, soil or regolith and flow downhill quickly. There are two main types - lahars, which are mudflows from volcanic eruptions composed of ash and debris, and debris flows, which are soil and rock mixtures that move like viscous fluids. Mudflows can be triggered by heavy rainfall, rapid snowmelt, or volcanic eruptions. They move quickly and cause significant damage to land, property, infrastructure, and loss of human life. After a mudflow, extensive cleanup is required.
Glacial melting contributes significantly to various global issues. As glaciers shrink due to climate change, they no longer help regulate the planet's temperature and provide fresh water. This leads to fresh water shortages, reduced agricultural production, electricity shortages from lack of hydroelectric power, excessive flooding, sea level rise that displaces coastal communities and destroys habitats, and the release of toxic pollutants that were stored in glacial ice. If glacial melting continues unabated, its effects will further exacerbate climate change in a dangerous feedback loop.
The document discusses the global distribution of tectonic hazards such as earthquakes, volcanoes, and tsunamis. It explains that most earthquakes occur along well-defined plate boundaries, including subduction zones where one plate slides under another, and collision boundaries. Narrow earthquake belts are associated with constructive margins where new crust is forming and plates are moving apart. Broadly, the document provides an overview of the types and causes of tectonic hazards around the world.
This document provides an overview of physical geography concepts related to rivers and coasts. It discusses the key processes that shape river landscapes including erosion, transportation, and deposition. It explains how rivers form V-shaped valleys and meanders. It also covers coastal landforms such as deltas, spits and cliffs, and the processes of longshore drift and coastal erosion. Examples are given of river flooding including the Boscastle floods of 2004 and factors influencing storm hydrographs.

This document discusses various coastal geological processes. It describes how coastal erosion occurs through hydraulic action, abrasion, attrition, and solution, forming features like wave-cut cliffs, platforms, sea caves, arches, and stacks. Coastal deposition happens when waves lose energy and drop sediment, forming features like spits, baymouth bars, sand bars, and barrier islands. Coastal inundation, or flooding, can result from storm surges, sea level rise, or tsunamis overtopping or breaching natural or man-made barriers. Coastal subsidence is also discussed, which is the sinking of coastal land caused by various geological processes.
The sea constantly changes coastlines through erosion, transportation, and deposition of material. Waves erode the coastline through processes like hydraulic action and abrasion, forming landforms such as cliffs, bays, and sea caves. Material is transported along the shore by swash and backwash and through longshore drift. Deposition by the sea creates beaches, sand dunes, sand spits, and lagoons. People build structures like sea walls, place boulders, and construct groynes to protect coastlines from erosion while also utilizing coastlines for tourism, industry, and recreation.
Sea Level Rise and Disappearing Islands: Myth or Reality?Greg Briner
Sea level rise and disappearing islands: myth or reality? This document discusses sea level rise and its impacts. It examines how fast sea levels are rising through various measurements from tide gauges and satellite altimetry. Islands like Tuvalu are most at risk from even small rises in sea level as they are very low-lying and could become uninhabitable. The document reviews projections for further sea level rise and its threats to islands and coastal areas over the coming decades and centuries.
Global warming will cause abrupt rises in sea levels, deforestation, and flooding in less than 50 years, affecting over 2 billion people according to recent research. The research also suggests that the amount of rain and floods have been increasing in recent years due to long-term human-caused climate change. Additionally, the studies find that rainfall has become even more extreme since the mid-20th century, with the observed changes being too strong and rapid to be solely caused by natural causes.
Glaciers are large masses of snow and ice that accumulate over time under their own weight and slowly flow outward. They are formed from accumulating snow, and their lower layers crack as they move due to their great size and weight. It is normal for glaciers to melt gradually as temperatures rise, but many glaciers today are melting faster than snow can replenish them, reducing their sizes and contributing to rising sea levels. There are different types of glaciers including alpine, continental, and valley glaciers.
The document is a New York Times article summarizing a recent EPA climate report commissioned by the Bush administration. [1] It acknowledges the severe environmental consequences the US will face from global warming, including rising sea levels and more extreme weather, but the administration has no plans to take action. [2] While a break from the administration's previous denial of climate change, conservatives strongly criticized even this recognition of the problem. [3] The president distanced himself from the report and said he had no plans to address global warming, despite the report's warnings about coming climate changes across the US.
Sea levels are rising due to global warming caused by human activities like burning fossil fuels. This is occurring through two main processes: 1) the oceans are warming and expanding as they absorb more heat, and 2) land ice such as glaciers and ice sheets are melting and adding water to the oceans. If warming continues on its current trajectory, sea levels could rise several more meters by 2100, significantly flooding many coastal cities and populations. This will have devastating environmental, economic, and social impacts around the world, especially in highly vulnerable areas like South Florida, Bangladesh, and small island nations.

The document discusses the causes and effects of global warming. It explains that the scientific consensus, as represented by the IPCC, is that human greenhouse gas emissions are the dominant cause of recent global warming. As the planet warms, it is leading to increased frequency and severity of natural disasters like hurricanes, floods and droughts. The melting of ice sheets is also causing sea levels to rise, which increases damage from storms. While some natural disasters remain steady, hydro-meteorological events like hurricanes have been increasing due to warming oceans and atmosphere providing more fuel for storms.

The document discusses the composition and structure of Earth's atmosphere. It describes the different layers of the atmosphere, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. It explains how solar energy is transferred throughout the atmosphere using radiation, conduction, and convection. The document also mentions clouds and the water cycle.
The document discusses sea level rise predictions for the Bay Area. It finds that global sea level is rising due to thermal expansion and melting ice sheets and glaciers. The Bay Area is experiencing higher localized sea levels from factors like tides, storms, and El Nino events. Models project 1.4 meters of sea level rise for the Bay Area by 2100, which will significantly increase flooding risks and inundate developed coastal areas. Environmental and social impacts include loss of wetlands and risks to coastal communities.
This document provides information about GCSE Geography revision on dynamic planet topics. It includes case studies on volcanoes like Mt St Helens and Nyiragongo, as well as earthquakes in Kobe, Japan and Sichuan, China. There are exam focus questions on plate tectonics, hazards and management. Additional sections cover climate change in the past and future, threats to biomes, and conservation efforts. Review materials include theory, graphs to interpret, and guidance on key topics to know for the exam.
Global warming is causing sea levels to rise faster than ever before due to melting ice sheets and glaciers. Over the last 100 years, sea levels have risen approximately 12-22 cm and are predicted to continue rising throughout the 21st century. Contributors to sea level rise include thermal expansion of oceans as they warm, and melting of glaciers and ice sheets in Greenland and Antarctica. Management strategies to deal with rising seas include reducing greenhouse gas emissions to slow warming, coastal defenses, and proposals to transfer large amounts of water from oceans to land storage.
The document analyzes tide gauge data from five locations in the UK to determine historical sea level rise. It finds an average rise of 1.56mm per year over the period of available data for each location. However, sea level rise varies locally due to land movement. GPS data shows southern England is subsiding by up to 1.2mm/year while Scotland rises by 1-2mm/year, influencing relative sea level changes. Accounting for these land movements, sea levels have risen by 0.9-1.1mm/year independently of land movement effects. Rising sea levels are a concern for coastal areas due to potential flooding impacts.
Most of the document discusses various coastal hazards such as hurricanes, tsunamis, rip currents, and erosion. It describes the processes that cause these hazards, including storm surge, waves, and sea level rise. It also discusses how population growth has led more people to live near coasts, exposing them to these risks. Finally, it examines various mitigation approaches like elevating buildings, early warning systems, and engineered structures to manage shoreline change.
This document reports on a project studying sustainable urban planning and global warming. It discusses several issues related to climate change: rising sea levels are causing problems for coastal cities; climate change is increasing both natural disasters like storms as well as temperatures and climate change impacts. Human activities like fossil fuel use are the main driver of increased greenhouse gases, trapping more heat and warming the planet. Higher temperatures and sea levels will significantly impact coastal areas through increased flooding, erosion, damage to infrastructure and intrusion of saltwater into freshwater supplies.
This document summarizes a presentation on climate change and its effects. It discusses:
1. Arctic warming is causing sea ice loss, which is accelerating faster than predicted and the Arctic could be ice-free in summers by mid-century.
2. Warming is not uniform and inland areas are warming twice as fast as oceans, increasing weather extremes like stronger monsoons and droughts/floods in some regions.
3. Sea level rise projections may be underestimated and could be 67% higher, threatening cities like Washington D.C. with a 6 meter rise.
4. Most mountain glaciers will be gone by 2050, endangering water supplies for 40% of
Sea levels are rising due to global warming caused by human activities like burning fossil fuels. The document discusses how sea level rise is accelerating, with levels projected to rise 40cm by 2100. This will increase flooding risks and damage coastal habitats and infrastructure. Countries like Bangladesh and the Philippines are especially vulnerable, as rising seas exacerbate existing flood and typhoon issues. Reducing greenhouse gas emissions to slow climate change is presented as the best approach to mitigating further sea level rise impacts.

Rising Seas and Extreme Storms: Similarities and differencesriseagrant
John Englander, oceanographer, consultant, and sea level rise expert discusses the science of sea level rise, its
economic impacts, and adaptation options for coastal businesses.
Global warming is threatening the planet through melting ice caps and rising sea levels. Scientific findings show the arctic regions are melting the fastest and areas like Europe, Alaska, Greenland are at high risk of flooding in the coming years. This is due to multiple factors like pollution depleting the ozone layer, acid rain eroding glaciers faster, and carbon emissions trapping heat. Recent data shows over 200,000 square miles less Arctic ice and melting rates of over 0.25 km of ice thickness per decade, contributing to rising temperatures worldwide.
The document discusses evidence that global warming is occurring, including rising average temperatures around the world since 1800 and the hottest decades being the last two of the 20th century. It notes that humans are releasing carbon dioxide faster than nature can absorb it. The effects of global warming described include melting glaciers causing sea level rise and changes to animal habitats and behaviors like hibernation patterns being disrupted. Solutions proposed include developing renewable energy and clean coal technologies as well as international cooperation on reducing carbon emissions.
Most of the earth is covered by ocean waters. Oceans are very important. They affect weather, and because of uneven heating from the sun, currents of warmer water flow through colder ocean water. Winds cause waves.
Rising Seas and Solutions, Sigma Xi LecturePaul H. Carr
Miami Beach becomes a flood zone during King High Tides. 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 Eckerd Colleges'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.
The document provides information about oceans and shorelines through a series of reading comprehension activities. It defines key terms like shore, headland, tide pool, and jetty. It describes how waves and erosion can change shorelines over time, forming features like beaches, cliffs, and rock formations. Human activities like construction can also impact shorelines by making beaches smaller or filling channels. The document notes that explorers are now able to travel deeper into oceans using technologies like diving bells, suits, and submarines, as well as remote-controlled vehicles.
The document discusses several ways that climate change is negatively impacting the oceans, including increasing ocean temperatures, acidification, sea level rise, and changes to ocean circulation patterns. These changes are disrupting ecosystems and threatening coral reefs and coastal communities. The oceans have absorbed over 90% of the increased atmospheric heat from climate change and are experiencing impacts that range from rising sea levels and stronger storms to changing ocean circulation currents and increasing acidification levels. If greenhouse gas emissions continue at their current rate, we risk losing coral reefs entirely within the next 20-30 years.
This document provides information about natural hazards and disasters. It discusses different types of natural events such as volcanic eruptions, hurricanes, and landslides that shape the Earth. It defines natural hazards as events that have potential to damage life and property, and natural disasters as hazards that cause significant fatalities or property damage. Examples of different types of hazards are also given, including climatic, tectonic, geomorphological, and technological hazards caused by human activity. Specific historic disasters like Hurricane Katrina and the 2004 Indian Ocean tsunami are discussed. Causes and impacts of flooding are explained in depth.
Scientists have mapped the remnants of a prehistoric landscape lying under the North Sea that was once above water. It contained human settlements, lakes, hills, coastlines, and rivers before being flooded by rising sea levels over 5,000 years ago at the end of the last ice age. The submerged landscape, called Doggerland, was larger than modern day Britain and was home to early humans and animals until it was overwhelmed by rising waters. Seismic data collected by oil companies revealed the sunken features of this lost world.
Volcanoes produce different types of lava and erupt in various ways, sometimes causing hazardous flows like pyroclastic flows and lahars. Mount Hood in Oregon exemplifies an andesitic stratovolcano that has produced lava flows and generated lahars through dome collapses, posing risks to nearby areas. The 1986 gas eruption from Lake Nyos in Cameroon killed over 1,700 people by releasing carbon dioxide that pooled in low-lying areas.
This document summarizes the relationship between global warming, sea level rise, and the melting of sea ice and continental ice sheets. It first discusses how increasing greenhouse gas emissions are causing global warming, which is melting both sea ice and continental ice reserves. However, it notes there is ambiguity about the rate of ice melting compared to the rate of sea level rise. The document then presents a conceptual model that differentiates the roles of sea ice, continental glaciers, and ice sheets in causing global or eustatic sea level rise. It concludes that while melting of continental ice sheets and glaciers, along with thermal expansion of the oceans, are responsible for recent sea level increases, melting of sea ice alone does not contribute to changes in global
Flash floods are sudden floods caused by heavy rain or dam failures that occur quickly in a small area. They can move large objects and destroy buildings. Common causes are heavy rainfall over 1 inch per hour, saturated ground, and rain in uphill areas. Effects include loss of life, environmental damage from pollution, and millions in property damage. They frequently occur in areas with steep terrain and bare ground and reports have increased in the US due to better reporting. A 2009 flash flood in Kentuckiana was caused by over 14 inches of rain in under an hour from a thunderstorm. It caused widespread flooding, closed the University of Louisville for $15 million in damages, and disrupted power for 20,000 customers.
This document provides information about coastal landforms, processes of erosion, and coastal management strategies. It begins with definitions of various erosional processes like corrasion, solution, and longshore drift. It then provides diagrams and explanations of how different coastal landforms like wave-cut platforms, stacks, and spits are formed through erosional processes. The document also discusses hard and soft engineering techniques used for coastal management, providing examples like sea walls, beach nourishment, and managed retreat. It analyzes case studies of coastal management in areas like Holderness Coast in the UK. Finally, it poses exam questions related to coastal landforms, processes, and managing development in coastal regions.
This document summarizes research on the impacts of climate change and how factors like rising sea surface temperatures and sea levels influenced Hurricane Sandy in 2012. It discusses observed trends in climate extremes from a UN report and projections for further temperature rise and sea level rise. Specific impacts to coastal flooding and hurricanes from rising seas are examined. The potential for even worse storms is considered if a storm like Sandy occurred during high tide or with warmer ocean temperatures like Irene. The risks of more frequent damaging flooding events in coming decades is also summarized. The document outlines ongoing modeling efforts to better understand how climate change may impact conditions in the Long Island Sound.

This document is a story told from the perspective of Davy Lowston, one of the men who were shipwrecked on the Open Bay Islands off New Zealand's coast in 1810. Lowston and nine other men were left on the islands to hunt seals, but the ship that was meant to retrieve them was lost in a storm. The men were stranded for over three years, suffering hardship from lack of food and shelter, before finally being rescued. Their story became immortalized in a folk song that spread among whalers and sailors, becoming New Zealand's oldest folk song known as "Davy Lowston."
Chris sees that the kākāpō parrot from New Zealand has been listed as one of the world's ugliest animals. He thinks this is unfair and starts a petition at school to have the kākāpō removed from the list. Many students sign the petition. Chris later learns that the purpose of the "Ugliest Animals" list was actually to raise awareness about endangered species, not just beautiful ones like pandas. While the kākāpō's inclusion was meant to draw attention to it, other students become interested in the other unusual animals on the list as well.
The poem "The Little Turtle" by Vachel Lindsay is about a turtle that lives in a box and swims in a puddle. It snaps at and catches a mosquito, flea, and minnow, but does not catch the speaker. The poem has 4 stanzas with rhyming lines and describes the actions of the turtle.

The crew of seven voyaging canoes observed the health of the Pacific Ocean over two years. Teone Sciascia sailed on the waka Haunui from Fiji to the Solomon Islands. He observed plastic rubbish and bits of wood floating far from land, indicating pollution problems. Near islands, he saw more trash and dead sharks floating at sea. The observations from the fleet suggest the ocean's health is declining and immediate changes are needed to protect it.
This document provides a template for students to complete a vocabulary four square activity, where they write a definition of a word, use it in a sentence, write a synonym for the word, and draw a picture of the word.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Scientists James Goff and Scott Nichol sought to explain how pebbles from the ocean floor ended up on cliff tops at Henderson Bay. Through examining evidence such as the rounded shape of pebbles, oral histories of tsunamis, and layers in a core sample from a nearby swamp, they determined that a massive tsunami caused by the underwater Healy volcano around 1450 AD washed the pebbles inland and destroyed Māori villages along the coast. The scientists' study of this event provided insights into New Zealand's geological history and the forces that have shaped the landscape.

Aiden was worried about bringing his secret favorite thing to school because he thought his classmates would laugh at him. However, on the first day back, he discovered that all the students had the same bright green bag from the Bigbarn store. Later, when the bags got mixed up, the teacher had each student open their bag to identify the owner. Surprisingly, no one laughed at the unusual items found in the bags, including a large bone, a dead frog, and a tea bag. When Aiden opened his bag to reveal his own secret item, again nobody laughed.
Isla invites her grandparents, Granny and Pop, to Grandparents' Day at her school. Granny and Pop travel a long way in their house truck from Nelson to attend. On the day of the event, Granny bakes muffins and they arrive late. During the activities, Pop loses the keys to the house truck.
The document outlines homework expectations and activities for terms 3 and 4 of 2015 for the Puketapapa Team. Students are expected to complete 1-2 homework activities per fortnight, with some shaded activities taking longer to complete. Students should submit their highest quality work via several methods. In addition to homework activities, students are expected to read daily, participate in Mathletics, and use SpellingCity. The document provides several homework activity options centered around financial literacy.
This term in P.E., students will learn invasion games like soccer, basketball, and rugby to practice skills and strategy related to possession, attacking, and defending. There will also be several inter-school sports competitions for netball, soccer, cross-country, and basketball. Students should bring their P.E. uniform daily and change into it before playing outdoors. P.E. sessions are scheduled on different days for different classes.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

Rising seas
1. by Kate Potter
Oceans cover almost three quarters of the
planet’s surface and contain 97 percent of the
water on Earth. It’s hard to believe, but this
vast amount of water is getting bigger. As a
result, sea levels are rising. So what does that
mean for those who live close to the sea?

This visualization shows the extent of Arctic sea ice on August 26, 2012, the day the sea ice dipped to its smallest extent ever recorded in more
than three decades of satellite measurements. The line on the image shows the average minimum extent from the period covering 1979-2010.
Every summer the Arctic ice cap melts down to what scientists call its “minimum” before colder weather builds the ice cover back up.
