Climate refugees are people who must leave their homes and communities because of the effects of climate change and global warming. Climate refugees belong to a larger group of immigrants known as environmental refugees. Climate refugees are people who must leave their homes and communities because of the effects of climate change and global warming. Climate change is caused by natural events, such as volcanic eruptions, as well as human activities, such as burning fossil fuels and cutting down forests. Climate change has happened many times since Earth was formed billions of years ago. Global warming is the most recent period of climate change. This term refers specifically to the increase in Earth’s average temperature as a result of rising levels of greenhouse gasses. Greenhouse gasses trap heat in the atmosphere and are released when fossil fuels are burned. Fossil fuels, which include coal, oil, and natural gas, are used to generate electricity, power vehicles, heat homes and commercial buildings, and produce a wide variety of goods. In general, wealthy, industrialized countries create the most greenhouse gas emissions but feel the smallest effect of climate change, while low-income, developing countries produce the lowest emissions but are the most at risk. Countries with lower emissions tend to be in geographical regions that make them more vulnerable to climate change issues, such as deserts and low-lying islands. They also have fewer resources available to prepare for climate emergencies and fund reconstruction efforts. Dry areas, like the Horn of Africa, and low-lying countries, like the Maldives, are already feeling the strain of climate change while producing relatively few emissions. 

These climate refugees belong to a larger group of immigrants known as environmental migrants. Environmental migrants also include people who are fleeing sudden-onset natural disasters, such as forest fires and flooding. National Geographic Explorer and photographer Siddharth Behl documents migration due to climate change in India and South Asia as part of a humanitarian effort to create more awareness. The United Nations reported that, in 2022, a higher percentage of refugees came from areas at risk because of climate change than ever before: from 61 percent in 2010 to 84 percent in 2022. A 2021 World Bank report estimated that, by 2050, the climate crisis could drive more than 200 million people to move. In 2020, the Institute for Economics and Peace put the number of people at risk of displacement by 2050 at over one billion, under the combined threat of climate change and civil unrest. 
Out of the 33 billion tons of carbon dioxide produced globally, each U.S. household contributes an average of 8–10 metric tons. Consumers can take a variety of actions to reduce their carbon footprint, from extending the life of goods and reusing materials to buying secondhand clothing and eating less meat. But individual actions alone cannot stop climate change. Indeed, 70 percent of emissions are created by just 100 companies. These large corporations have battled against laws and regulations intended to curb emissions. 
Sea-Level Rise.......Rising temperatures associated with global warming cause glaciers and ice caps to melt, which in turn leads to higher sea levels. This increase in sea levels contributes to flooding and can put land completely underwater, making it uninhabitable.  Global Heating.... cause glaciers and ice caps to melt, which in turn leads to higher sea levels......read on, there's much more https://education.nationalgeographic.org/resource/environmental-refugee/
