Learn about one of the most serious issues facing the human species: climate change
Global climate change describes a change in the average conditions — such as temperature and rainfall — over a long period of time. Scientists have observed Earth’s surface is warming, and many of the warmest years on record have happened in the past 20 years. Changes in global temperatures are impacting people and the planet, causing rising sea levels and flooding, more frequent and powerful extreme weather events like hurricanes and snowstorms, droughts and heat waves, and other dangerous conditions.
There are many factors that contribute to Earth’s climate, however, scientists agree that humans are making Earth heat up faster. Certain gases in Earth’s atmosphere block heat from escaping, keeping the planet warm just like a glass in a greenhouse keeps plants warm. Human activities - such as burning fuel to create electricity, collecting trash in large landfills, and big factories and farms - release "greenhouse gases" into the atmosphere and make Earth warmer. Climate change will dramatically change the way humans live on this planet and have major effects on our communities, health, food, and more.
