Guide to Global Climate Change

Sure, Earth's climate has changed before. But this time is different. People are causing global warming, and the changes to our climate are bigger and happening faster than anything we’ve ever seen before.

Glaciers are melting. Hurricanes and winter storms are growing stronger. Get the basics on climate change and how it’s affecting people, animals, and entire ecosystems.
