Global warming is causing a number of drastic changes to the Earth’s climate. Rising temperatures are melting polar ice caps, leading to rising sea levels, extreme weather events, and increased acidification of the oceans. This is causing habitats to be destroyed and species to become extinct. It is also leading to more frequent and intense droughts, floods, and other natural disasters. Global warming is also contributing to an increase in air and water pollution, which can have serious health impacts for humans and other species.
