9 facts about global warming that you must definitely know

The document outlines nine critical facts about global warming, noting that 2016 was the hottest year on record and that the Earth's average surface temperature has risen approximately 1.1 degrees Celsius since the late 19th century. It attributes this warming primarily to man-made greenhouse gas emissions, specifically carbon dioxide from burning fossil fuels and deforestation. The text details environmental consequences including rising sea levels, the loss of polar ice, coral reef bleaching, and a tripling of climate-related disasters since 1980. It also highlights human impacts, such as the displacement of 22.5 million people by weather-related disasters between 2008 and 2015 and threats to food and water security.

• Global temperatures are on a long-term warming trend, with 2016 being the hottest year on record and the Earth's average surface temperature increasing by about 1.1 degrees Celsius since the late 19th century.
• The current rapid warming is primarily caused by human activities, such as deforestation and the burning of coal, oil, and natural gas, which have increased atmospheric carbon dioxide by more than one third since the start of the Industrial Revolution.
• Climate change is causing significant environmental degradation, including the loss of 50% of the world's corals over the last 30 years and the loss of approximately 50,000 square miles of forest annually.
• The IPCC projects that sea levels will rise by 52-98cm by the end of the century if greenhouse gas emissions continue to grow, or 28-61cm if they are significantly reduced.
• Human populations are increasingly affected by climate change, with the UNHCR reporting that 22.5 million people were displaced by weather or climate-related disasters between 2008 and 2015.
