This document discusses the causes and effects of climate change. It explains that the term "global warming" was first used in an article in the 1980s. Potential causes include increased greenhouse gases from human activities like burning fossil fuels, deforestation, volcanic eruptions, and certain agricultural practices. Effects already occurring include melting ice caps and permafrost in the Arctic and rising sea levels globally. If unchecked, climate change could lead to the loss of natural areas like rainforests and coral reefs. The document outlines ways to respond through reducing carbon emissions and adapting to impacts.
