Climate change denial

Climate change denial is when people say that climate change (when the Earth's climate gets warmer and changes over time) is not real or doesn't exist. Basically, people who deny climate change don't believe that the Earth is getting warmer because of things that people do, like burning fossil fuels. They may also think that the effects of climate change, like melting glaciers and rising sea levels, are not really happening or are natural events.
