Earth's climate naturally changes, but since the 1800s, global temperatures have risen at an unprecedented rate. Many scientists have attributed this climate change to the increased use of fossil fuels. Climate Change examines how human activities have contributed to global warming and the effects climate change has on the planet. It also looks at steps being taken to mitigate climate change, ways in which activists have taken action to reduce greenhouse gas emissions, and how everyday people can get involved. Features include a glossary, references, websites, source notes, and an index.
