The science of climate change is complex, but everyone should know the basics: the Earth is heating up because gases produced from vehicles, power plants, deforestation, and other sources are building up in the atmosphere, acting like a thick blanket over our planet.

We can all reduce climate change by doing our part to decrease the emission of heat-trapping gases to the atmosphere. Read below to learn some more facts about climate change!
