The Great Lakes region is warming faster than the rest of the U.S., a trend likely to bring more extreme storms while also degrading water quality, worsening erosion and posing tougher challenges for farming, scientists reported Thursday.

The annual mean air temperature in the region, which includes portions of the U.S. Midwest , Northeast and southern Canada, rose 1.6 degrees (-16.9 Celsius) from 1901-60 and 1985-2016, according to the report commissioned by the Chicago-based Environmental Law & Policy Center. During the same periods, the mean temperature for the remainder of the contiguous U.S. rose 1.2 degrees (-17.1 Celsius).

Century - Rates - Volume - Gases - Carbon

Warming is expected to continue this century, with rates depending on the volume of heat-trapping gases such as carbon dioxide and methane that humans pump into the atmosphere. As the air warms, it will hold more moisture, which likely will mean heavier winter snowstorms and spring rains—with more flooding in vulnerable areas. Yet summers will be hotter and drier.

"Over the last two centuries, the Great Lakes have been significantly impacted by human activity, and climate change...
