The data is sobering.
Global average temperatures have risen dramatically, and current emissions indicate further warming unless significant intervention occurs. 

Sea levels are rising at record rates.
Climate models from NASA and the Intergovernmental Panel on Climate Change (IPCC) point in the same direction. Continued warming unless global emissions are curbed.

There is a broad scientific consensus. Thousands of climate scientists across dozens of nations agree that recent warming is primarily caused by human activities.
