Temperatures are definitely rising...

Thousands of studies conducted by researchers around the world have documented increases in temperature at Earth’s surface, as well as in the atmosphere and oceans.

Many other aspects of global climate are changing as well. High temperature extremes and heavy precipitation events are increasing, glaciers and snow cover are shrinking, and sea ice is retreating.

Seas are warming, rising, and becoming more acidic, and flooding is become more frequent. Growing seasons are longer, and large wildfires occur more frequently. Many species are moving to new locations, and changes in the seasonal timing of important biological events are occurring in response to climate change.
