Many locations in the Midwest, Northeast, and Gulf Coast are having one of their 10 wettest summers on record so far, with northern Illinois being especially wet.

Increasing heavy precipitation is one of the strongest indications of climate change. As the world warms from the increase of greenhouse gases, there is an increase in evaporation, as a warmer atmosphere allows for more evaporation, and in turn, more water available as precipitation. Below are some links to graphics to help with tie together the weather and climate connection.
