The document discusses global warming and provides evidence that the Earth is warming due to human activity. It summarizes that the average global temperature has increased by 1 degree Fahrenheit over the past century, and that this warming is caused by increased greenhouse gas emissions from human use of fossil fuels. The document also lists several impacts of global warming, such as melting glaciers and sea ice, disrupted ecosystems, and more extreme weather events like hurricanes. Finally, it suggests individual actions people can take to reduce their carbon footprint and greenhouse gas emissions to help address the problem.
