The last ice age ended due to a rise in atmospheric carbon dioxide levels driven by increasing temperatures. Scientists analyzed data from shells of ancient ocean creatures finding CO2 levels rose from 180 parts per million at the end of the ice age to 260 parts per million. Higher CO2 levels further increased temperatures, causing the ice sheets of the northern hemisphere to collapse and end the last ice age.

Global Warming
Global warming is caused by increased carbon dioxide and other greenhouse gases trapping heat in the atmosphere. Scientists have observed the impacts of rising temperatures, including melting ice caps and glaciers which raises sea levels and could flood coastal areas. As temperatures continue increasing due to fossil fuel usage, extreme weather, spread of diseases, and damage to coral reefs are projected to worsen. The effects of climate change have accelerated over the past 150 years due to human activity releasing greenhouse gases.
Presentation1 ict climate change
Climate change is one of the biggest crises facing humanity and is defined as a shift in worldwide weather patterns associated with rising global temperatures, predominantly caused by burning fossil fuels which release heat-trapping gases. Some of the evidence of climate change includes rising sea levels and global temperatures, warming oceans, shrinking ice sheets, declining Arctic sea ice, retreating glaciers, more extreme weather events, and increased ocean acidification. Many indicators, such as rising sea levels, temperatures, and ocean warming, show the effects of climate change are already occurring.

Climate is defined as weather patterns over decades and centuries, measured by precipitation and temperature. The document discusses how climate has always changed naturally, but human activity has increased greenhouse gases and accelerated the current warming trend. If the warming trend continues unchecked, sea levels are projected to rise over 20 feet and global temperatures over 12 degrees Fahrenheit within the next century, with significant impacts to ecosystems and human civilization.

This document summarizes the latest climate science from the Met Office and its implications for Wales. It discusses increasing global temperatures, rising carbon dioxide levels, extreme weather events, and projections showing continued warming if emissions are not reduced. Climate models are improving but still have uncertainties around factors like ocean heat uptake. The impacts of 4°C warming could include drought, flooding, reduced crops, and effects on billions of people. Improving model resolution helps understand regional implications like for Welsh terrain and rainfall.Global warming
Global warming is caused by increased carbon dioxide and other greenhouse gases trapping heat in the atmosphere. This is melting polar ice caps and glaciers, causing sea levels to rise and threaten coastal areas. As temperatures increase, animal populations are declining and coral reefs are bleaching. Over the past 150 years, temperatures have risen more than in previous centuries due to increased fossil fuel usage and carbon dioxide emissions. To slow global warming, carbon dioxide production must be reduced by conserving fossil fuel usage.
Rising Oceans
1) Global temperatures have risen over the past few decades and are projected to continue increasing due to rising carbon dioxide levels from fossil fuel usage.
2) Warming effects will be greater at higher latitudes and polar regions, and land areas will warm more rapidly than oceans.
3) Melting glaciers are contributing significantly to rising sea levels, which are estimated to be rising at 1.5 to 2 millimeters per year.

Climate change is having ecological effects on the Chesapeake Bay. Increased storms and flooding from climate change leads to higher loads of pollutants entering the Bay. Rising temperatures stress species and could eliminate some. Species' ranges are also shifting. Warmer water holds less oxygen. Sea levels have risen over the last 30-40 years more than three times the global average, flooding coastal areas. Multiple pollution reduction efforts called for in Virginia's cleanup plan would help reduce greenhouse gas emissions, flooding, and increase resiliency while filtering pollutants.

Conclusions
Ocean Mixed Layer Temperatures for both models are very similar, showing that the ocean conditions for the LGM and future climate underwent the same conditions at some point, could lead to colder temperatures
With this data alone available, we must infer that there could be a climate change due to melting of ice into the ocean, until there is more data to back up the hypothesis
EdGCM limits the amount of information we can compare
○ Only 100 years of predicted models
○ Not as many parameters available to model
Sea Level Rise: Global and California data and projections
Sea levels are rising globally due to increasing temperatures driving thermal expansion of oceans and melting of land ice. Based on data from 1993-2010, global sea levels rose an average of 3.2 mm per year, and are projected by the IPCC to continue rising throughout the 21st century at an accelerated rate compared to 1971-2010. In California, indicators show sea levels rising along the coast, with state projections aligning with global projections of increasing sea level rise due to climate change throughout the current century.
Donald Boesch Blue Planet Forum Presentation
Climate change is primarily caused by human activities like greenhouse gas emissions. The global surface temperature has increased about 1 degree Celsius compared to pre-industrial levels and climate models show this warming can only be explained when including human factors like greenhouse gases. Most of the observed warming is due to human activities according to the IPCC. Continued greenhouse gas emissions will lead to greater warming, raising risks like sea level rise which is accelerating and will inundate coastal areas. Drastic reductions in emissions are needed to limit global warming to well below 2 degrees Celsius.
Powerpoint.
Global warming is occurring and causing average temperatures worldwide to increase. The last few decades have been the hottest in over 400 years. As the planet warms, Arctic ice caps and glaciers are melting, sea levels are rising, and extreme weather events are becoming more common. Many signs indicate the climate is changing due to warming temperatures, including bleaching of coral reefs, earlier springs and later falls, and shrinking Arctic sea ice. Unless addressed, global warming will continue to have damaging environmental and economic effects across the globe.

Climate change
The document summarizes the key findings from IPCC reports on the likely impacts of climate change. It discusses that global surface temperatures are projected to increase 1.1-6.4°C by 2100, higher than any warming seen in the last 650,000 years. Precipitation patterns will be disrupted and extreme weather events will increase in severity and frequency. Sea levels are projected to rise 18-59 cm by 2100 but could be higher depending on ice sheet melting. Some climate changes such as ocean warming and sea level rise will continue for centuries.
Theglobalwarming
1) Global warming refers to the long-term rise in the average temperature of the Earth from the greenhouse effect caused by increased carbon dioxide and other human emissions.
2) Evidence shows the climate is warming, with land temperatures increasing about twice as fast as ocean temperatures since 1979.
3) External factors like changes in greenhouse gases, solar activity, and volcanic eruptions can cause the climate to warm or cool by altering the Earth's energy balance. Human emissions have likely contributed to observed changes like sea level rise and declines in Arctic sea ice.

The document summarizes evidence of climate change from various scientific studies including:
1) Increasing carbon dioxide and global temperatures over the past century.
2) Considerable mass loss and reductions in glaciers worldwide, including a 50% loss of glaciers in European Alps between 1850-1980.
3) Sea level rise of 20cm over the past century and currently rising at 3.2mm/yr.
4) Climate models project that temperature and sea level rise will continue to accelerate if emissions are not reduced.Implications of Climate Change
Climate change is a variation in weather patterns over decades to millions of years caused by factors like biotic processes, solar radiation, plate tectonics, volcanic eruptions and human interference. The document discusses the global implications of climate change such as increasing average global temperatures by 2 to 11.5 degrees F by 2100 depending on greenhouse gas emissions. Other implications are changes in precipitation patterns, loss of sea ice, sea level rise, and ocean acidification. Global sea level has risen about 8 inches since 1870 and is projected to rise faster than the past 50 years.
AP Environmental Science Ch. 19, part 1 Miller LITE
This document discusses evidence of climate change from various scientific sources. It notes that temperatures are rising globally, with the hottest years on record occurring recently. Various indicators are changing as well, such as glacial melting, sea ice shrinkage, and sea level rise. The evidence demonstrates that climate change poses serious risks and is largely due to human activities like burning fossil fuels. Understanding changes in the climate over past centuries and millennia relies on scientific data from sources like ice cores, tree rings, and ocean sediments.
Climate changes past and future
- Climate change occurs on various timescales and is influenced by factors like solar activity, Earth's orbit, atmospheric composition and greenhouse gases, volcanic eruptions, and human activities like fossil fuel burning.
- Evidence from geology and fossils shows past climate changes, including intervals warmer than today and ice ages. The last ice age peaked around 20,000 years ago and glaciers have since retreated.
- Future climate is uncertain but computer models predict global warming and changing precipitation patterns if CO2 doubles from current levels due to feedbacks like ice-albedo and water vapor effects. Careful study of past and present helps understand complex climate system.
Global Warming 101, Grades 3-6 (2013 Version)
This document aims to explain the key concepts of the greenhouse effect, climate change, and global warming. It defines each term and explains that global warming is caused by the buildup of greenhouse gases from the burning of fossil fuels. Evidence that climate change is occurring includes rising global temperatures over the past 1000 years as recorded from both temperature data and carbon dioxide levels in the atmosphere. Other signs include shrinking glaciers, changing lake ice cover, and rising sea levels. The document seeks to answer why climate change is happening by linking it to increasing carbon dioxide emissions since the Industrial Revolution and the human activities that produce greenhouse gas pollution such as burning coal, natural gas, and oil.
Global warming test
Global warming is caused by carbon dioxide and other greenhouse gases trapping heat in the atmosphere. This is warming the earth and melting ice caps and glaciers, which causes sea levels to rise and threatens coastal areas. As temperatures increase, climate changes are altering ecosystems and threatening plants and animals through shifting habitats and increased droughts and fires. The rapid warming seen in recent decades is unprecedented and is primarily due to human emissions of carbon dioxide from fossil fuel usage. Unabated, global warming will continue to have damaging environmental and economic consequences.
What climate changes are likely
This document summarizes the key findings from the IPCC reports on the likely impacts of climate change. It predicts increases in global surface temperatures from 1.1 to 6.4°C by 2100, greater warming at high latitudes, changes in precipitation patterns, more extreme weather events, and sea level rise of 18 to 59 cm and potentially over 1 meter. The impacts are projected to include worsening droughts, stronger storms, and threats to coastal infrastructure from rising seas.
IPCC AR5 – Science on Climate Change and future projections for South Asia
IPCC AR5 – Science on Climate Change and future projections for South AsiaClimate Action Network South Asia
The document summarizes key findings from the IPCC's Fifth Assessment Report regarding climate change projections for South Asia. It finds that human activity is the dominant cause of warming since the 1950s. If emissions continue at a high rate, the Arctic Ocean will likely be ice-free in summers by 2050. South Asia will experience increased temperatures, rainfall, and sea level rise by mid-century, posing challenges for coastal areas, agriculture, and infrastructure. Adaptation and mitigation efforts are needed to reduce impacts.Climate Change 101
Climate change poses significant risks to businesses. Increasing greenhouse gases from human activity are causing global temperatures to rise faster than ecosystems and societies can adapt to. The majority of climate scientists agree that climate change trends are extremely likely due to human activities. If greenhouse gas emissions continue at their current rate, the economic costs of climate change are projected to increase substantially by 2050 due to risks like rising sea levels, more frequent extreme weather events, water shortages, and decreased agricultural production. However, setting ambitious greenhouse gas reduction targets aligned with scientific recommendations could help save businesses up to $190 billion annually by 2020 through energy efficiency and renewable energy.
Long term & short term effects of climate 2
The document discusses long and short term changes in climate. Long term changes occurring over millions of years are influenced by continental drift and changes in Earth's orbit. Short term changes occurring over decades to thousands of years can be caused by volcanic eruptions, fluctuations in the sun's radiation, and shifts in ocean and air currents. Major long term climate shifts are also linked to variations in Earth's axial tilt, orbital shape, and the wobbling direction of its axis.
AP Environmental Science Ch. 19, part 2
Potential and realized consequences of climate change include:
1) Drought, melting ice, rising sea levels, and permafrost melt are already occurring as a result of climate change.
2) Additional potential consequences that some experts say may already be happening include altered ocean circulation patterns and more extreme weather events.
3) Further potential consequences include threats to biodiversity like coral bleaching and disrupted animal migration patterns, shifting agricultural production, and risks to human health from factors like heat waves.
Global Warming
1. Global warming is caused by increased levels of greenhouse gases like carbon dioxide trapping more of the sun's heat in the lower atmosphere.
2. Ice core data provides evidence of past climate conditions, showing that temperature and carbon dioxide levels rise and fall together over hundreds of thousands of years.
3. Current carbon dioxide levels are higher than at any time in the past 800,000 years and global temperatures are rising, threatening ecosystems, human health, and coastal communities through more severe weather events and sea level rise.

Little Red Riding Hood
This document summarizes and analyzes different versions of the "Little Red Riding Hood" fairy tale. It discusses the original Brothers Grimm version from 1812 and Charles Perrault's 1697 version. It also examines modern adaptations from the 20th century where Little Red Riding Hood fights back against the wolf, including versions by James Thurber, Ronald Dahl, and Chiang Mi. The document suggests the moral message of the story may have changed in these modern adaptations where the victim fights back rather than remains helpless. It also discusses how some revisions aimed to deconstruct traditional gender stereotypes in fairy tales.

Little Red Riding Hood
Little Red Riding Hood goes to visit her grandmother, carrying a basket of goods. Along the way, she stops to pick flowers and loses track of time. A wolf approaches her and asks where she is going. She tells him she is visiting her grandmother. The wolf arrives at the grandmother's house first and eats her. He then waits in her bed disguised as the grandmother. When Little Red Riding Hood arrives, she realizes it is the wolf. A woodsman hears her cries for help and rescues the grandmother from the wolf. Little Red Riding Hood learns not to talk to strangers or wander in the forest.
English lesson plan
This English lesson plan focuses on teaching primary school students about the story of Little Red Riding Hood through 5 sessions. The plan aims to improve students' vocabulary, reading, listening and speaking skills in English. Over the 5 sessions, students will listen to and read the story, learn related vocabulary like family members and body parts, review content through games and songs, and consolidate their learning.

Is global warming a myth
The document provides evidence that global warming is occurring due to human activity. It notes that carbon dioxide emissions have increased, most of the world has warmed, Arctic and Antarctic ice caps are melting faster than previously thought, global sea levels have risen 10-25 cm in the last century, and the greenhouse effect is trapping more heat due to increased greenhouse gases like carbon dioxide and methane. While some natural climate variability occurs, mainstream scientists believe human emissions are enhancing the greenhouse effect and warning the planet, threatening life if emissions are not reduced. Burning fossil fuels also creates pollutants that cause "global dimming" by making clouds more reflective, offsetting warming slightly.
Melting polar ice caps
The polar ice caps are melting at an increasing rate due to human-caused climate change. Studies from 2013 estimated that if melting continues, sea levels would rise 66 meters over the next 5,000 years. The main cause is carbon dioxide emissions which are enhancing the greenhouse effect and warming the planet's temperatures. As the ice melts, it has consequences like reduced albedo and sea level rise, as well as potential methane emissions from marine permafrost and changes to ocean currents. The extent of summer sea ice has declined significantly over the last few decades in both polar regions.

Greenhouse effect
The document discusses the greenhouse effect and greenhouse gases. It explains that greenhouse gases like carbon dioxide and methane trap heat in the atmosphere, warming the Earth's surface like the glass of a greenhouse. Without these natural greenhouse gases, the Earth would be too cold to support life. It then outlines how human activities like burning fossil fuels are increasing greenhouse gas levels and contributing to global warming and its impacts.
The global warming
Global warming refers to the long-term rise in the average temperature of the Earth from human industrial and agricultural activity. Evidence shows the climate is warming, with land temperatures increasing almost twice as fast as ocean temperatures due to higher heat capacity of oceans. External factors like increased greenhouse gases and changes in solar activity can cause the climate to warm or cool. Human greenhouse gas emissions have likely contributed to changes like sea level rise, extreme weather events, and reduced Arctic sea ice. Long-term global warming will be determined by how much carbon dioxide and other greenhouse gases are emitted.
What is climate change doing to us and for us?
What are we doing to our climate? Emissions from fossil fuel burning have raised carbon dioxide concentrations 35% higher than in the last millions of years. This increase is warming our planet via the Greenhouse Effect. What is climate change doing to and for us? Dry regions are drier and wet ones wetter. Wildfires have increased threefold, hurricanes more violent, floods setting record heights, glaciers melting, and seas rising. Parts of Earth are increasingly uninhabitable. Climate change requires us to act as a global community. Climate justice enjoins emitters to pay the social-environmental costs of fossil fuel burning. This would expedite green solar, wind, and next-generation nuclear energy sources. Individuals should conserve resources, waste less food, and eat a plant rich diet.
The global-warming
Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.
Multiple lines of scientific evidence show that the climate system is warming.
Temperature changes vary over the globe. Since 1979, land temperatures have increased about twice as fast as ocean temperatures. Ocean temperatures increase more slowly than land temperatures because of the larger effective heat capacity of the oceans and because the ocean loses more heat by evaporation
Global Warming Of The 21st Century Slide Show
Global warming is a controversial issue with uncertain causes according to the document. While the IPCC argues that human carbon dioxide emissions are the main driver of recent warming, the document notes there are other potential natural causes like the sun, extraterrestrial dust, and changes in cloud cover. The document reviews the evidence for both human and natural causes of climate change and periods of past warming and cooling like the Roman Warming, Dark Ages, Medieval Warming and Little Ice Age. It concludes that climate has varied naturally over millions of years and scientists are still uncertain if current warming is predominantly human-caused or part of this natural variability.
Global Climate Change And Ocean Current
Global warming over the past century is likely caused by increased greenhouse gas emissions. This warming could significantly slow the Atlantic Thermohaline Circulation, an ocean current that transfers warm water to the North Atlantic. A slowing of this current could lead to colder temperatures in the northern hemisphere and warmer temperatures in the southern hemisphere. It may also increase regional climate variability and impact weather patterns globally. International cooperation on reducing greenhouse gas emissions through agreements like the Kyoto Protocol is needed to address climate change.
Science climate project
Long and Short Term Changes of Climate discusses various factors that cause changes in climate over both small and long terms. Small-term changes are caused by volcanic eruptions, small variations in solar radiation, and shifts in air and ocean currents. Long-term changes are influenced by changes in Earth's energy balance, orbital variations, glacial activity, plate tectonics, and human influences like fossil fuel usage. The document also discusses how climate change can affect animals and ecosystems, as well as how scientists monitor and study climate change.
Global Warming

BEYOND LIMITS: WHERE WE'RE HEADED
ECOLOGY
How far can we push the planet?
BUSINESS, GOVERNMENT OR TECHNOLOGY forecasts usually look five or 10 years out, 50 years at most. Among climate scientists, there is some talk of century's end. In reality, carbon dioxide dumped into the atmosphere today will affect Earth hundreds of thousands of years hence.
How will greenhouse gases change the far future? No one can say for sure exactly how Earth will respond, but climate scientists -- using mathematical models built from knowledge of past climate systems, as well as the complex web of processes that impact climate and the laws of physics and chemistry -- can make predictions about what Earth will look like.
Already we are witnessing the future envisioned by many of these models take shape. As predicted, there has been more warming over land than over the oceans, more at the poles than near the equator, more in winter than in summer and more at night than in the day. Extreme downpours have become more common. In the Arctic, ice and snow cover less area, and methane-rich permafrost soils are beginning to melt. Weather is getting weirder, with storms fueled by the additional heat.
What are the ultimate limits of the change that we are causing? The best historical example comes from the 100-million-year-old climate of the Cretaceous period, when moist, hot air enveloped dinosaurs' leathery skin, crocodilelike creatures swam in the Arctic and teeming plant life flourished in the CO2-rich air. The greenhouse that is forming now will have consequences that last for hundreds of thousands of years or more. But first, it will profoundly affect much of life on the planet -- especially us.
A DESERT IN ITALY
ONE OF THE GREATEST uncertainties in climate prediction is the amount of CO2 that will ultimately be released into the atmosphere. In this article, I will assume industrial civilization will continue to do what it has been doing for the past 200 years -- namely, burn fossil fuels at an accelerating rate until we can no longer afford to pull them out of the ground.
Just how much CO2 could we put into the atmosphere? All told, there are about one quadrillion metric tons (1021 grams) of organic carbon locked up in Earth's sedimentary shell in one form or another. So far we have burned only one twentieth of 1 percent of this carbon, or roughly 2,000 billion metric tons of CO2.
With all the carbon locked in Earth's crust, we will never run out of fossil fuels. We are now extracting oil from tar sands and natural gas from water-fractured shale -- both resources once thought to be technologically and economically inaccessible. No one can confidently predict just how far ingenuity can take us. Yet eventually the cost of extraction and processing will become so high that fossil fuels will become more expensive than alternativ ...
2 global warming is real cr
Global warming is real and caused by human activity. The burning of fossil fuels has increased the amount of greenhouse gases like carbon dioxide in the atmosphere beyond what the Earth can absorb naturally. Studies show that small increases in CO2 have led to temperature shifts in the past, and CO2 levels are now higher than in the last 650,000 years. If emissions continue, the effects will include rising sea levels from melting ice caps, flooding of coastal areas, shifts in weather patterns, and more severe storms. The past few decades have been the hottest in centuries, and the Arctic is already experiencing twice the global average warming. Multiple studies find the current warming trend can only be explained by human-caused greenhouse gas emissions.

Global warming is real and caused by human activity. The burning of fossil fuels has increased the amount of greenhouse gases like carbon dioxide in the atmosphere beyond what the Earth can absorb naturally. Studies show that small increases in carbon dioxide have led to temperature shifts in the past, and human activity has increased CO2 levels more than 30% above pre-industrial levels, the highest in 650,000 years. If emissions continue, the effects will include rising sea levels from melting ice caps, shifting weather patterns, and more severe storms. The past few decades have been the hottest in centuries, with the Arctic warming twice as fast as the rest of the world.

Norvergence Analysis of the Siberian Heat Wave
The Arctic heatwave in Siberia saw temperatures reach 100 degrees Fahrenheit in early summer, highlighting the rapid warming of the Arctic region over the past 30 years. As the Arctic warms twice as fast as the rest of the world, permafrost is increasingly melting and releasing trapped greenhouse gases. This is exacerbated by the loss of reflective sea ice, leaving darker land and water that absorbs more heat. Researchers are concerned this positive feedback loop could accelerate climate change impacts across the globe.
Global warming
The document summarizes the scientific evidence and consensus on climate change. It explains that human emissions of greenhouse gases are trapping heat and causing the planet to warm at a rate not seen in centuries. This is melting ice, raising sea levels, and shifting weather patterns in ways that threaten ecosystems and human communities. While uncertainties remain, most climate scientists agree that significant impacts are already occurring and will increase substantially if emissions are not reduced.
Presentation On Global Warming
This document discusses global warming and its causes, effects, solutions, and future impacts. It begins by defining global warming as the increasing average air temperature near Earth's surface over the past one to two centuries, caused by increased greenhouse gases like carbon dioxide, methane, and nitrous oxide. The document then lists key causes of global warming like emissions from fossil fuel use, deforestation, and industrial activities. Effects mentioned include rising temperatures, changing precipitation patterns, melting ice, and more frequent extreme weather. Solutions proposed center around transitioning away from fossil fuels to renewable energy and making lifestyle changes to reduce emissions and resource use. The conclusion warns that global warming poses major threats and will exacerbate issues like sea level rise, ocean acidification
Global_warming_presentation.pptx
Global warming refers to the rising average temperature of the Earth's atmosphere and oceans over time. The document discusses the causes of global warming, including increased carbon dioxide and methane emissions from human activities like burning fossil fuels and deforestation. The effects of global warming include rising sea levels, more extreme weather events, species extinction, and changes to agricultural yields. While global warming continues to occur, reducing carbon emissions from fossil fuels and preserving carbon sinks can help control the problem.
Climate Change.pptx
The document discusses several key topics related to climate change:
1) It describes greenhouse gases and their role in trapping heat and causing global warming.
2) Factors that influence climate such as latitude, oceans currents, and wind patterns are explained.
3) Evidence of a warming planet through rising temperatures, changing precipitation patterns, melting ice sheets and glaciers, and rising sea levels is presented.
4) Both current and future effects of climate change on organisms, agriculture/forestry, economies, and human health are outlined.
Global Warming
Global warming is caused primarily by human-induced increases in greenhouse gas emissions such as carbon dioxide and methane. The average global surface temperature has increased around 1°C over the past century and is projected to rise another 1-6°C by 2100 according to climate models. This warming will cause sea level rise and changes in weather patterns through feedback loops like increased water vapor and reduced ice and snow cover. There is an ongoing public debate around climate change and potential policy responses like emissions reductions and adaptation measures.

Co2 'drove end to last ice age'
- 1. * CO2 ‘Drove end to last Ice Age' By: Diane Torres
- 2. About the article The last ice age was ended by a rise in temperature driven by an increase in atmospheric carbon dioxide.They found very broad range of data, including shells of ancient tiny ocean animals. The team behind this study says this may has something to do with global warming. "At the end of the last ice age, CO2 rose from about 180 parts per million (ppm) in the atmosphere to about 260; and today we're at 392.
- 3. What was learned from the article. This may have to do with the change in the Earth's orbit around the Sun because it increases the amount of light reaching northern latitudes and triggers the collapse of the hemisphere's great ice sheets According to the studies because of this ,fresh water that enters the North Atlantic to upset ocean circulation is produced. The heat on the equator usually distributes northwards then backs up, now it’s raising the temperature in the South This causes more changes to world and ocean circulation, which causes the Southern Oceans to release CO2 from its waters When CO2 rises the temperature rises and there is a big change in the climate.
