Evidence for climate change
Evidence for climate changeFree13:57Heddy Score 3 of 7, below the standard
What you need to know
- Climate is the average of weather over a long time, not a single hot or cold day.
- Greenhouse gases from burning fossil fuels are raising Earth's temperature.
- Ice cores and the measured rise since industrial times are evidence that the change is already under way.
- The extra heat shows up as stronger storms, droughts and heatwaves, rising seas, and stress on living things, including people.
