The global temperature record of the past century shows that  Earth is warming at an unprecedented rate. 2024 was the hottest year on record, and the past 10 years have been the warmest in recorded history. Each of the last four decades has been warmer than any decade that preceded it, dating back to 1850.

This global warming has been caused by human activities, primarily the emission of heat-trapping greenhouse gases, according to the 2023 synthesis report of the Intergovernmental Panel on Climate Change. And we’re seeing the impacts in heat waves, wildfires, intense rainfall, and coastal flooding.
