evidence: What temperature we reach depends on our choices regarding greenhouse gases now. Here are six ways climate change is predicted to affect our everyday lives throughout the U.S. by 2100, with more severe consequences if emissions remain unchecked. [...] By 2100, hot days reaching dangerous conditions are expected to be three to ten times more frequent in the U.S. even if current emissions are limited to meet global climate goals set in Paris in 2015. [...] Continually rising sea levels mean flooding will likely happen more often. Some models project average sea level to rise along U.S. coasts by two feet by 2100 because of emissions to date, but more extreme scenarios show it could rise up to seven feet if we fail to curb future emissions. A sea level rise of just three feet would threaten the homes of 4.2 million people, according to one study. The researchers found the Southeastern U.S. will be most affected by rising sea levels: Florida is severely at risk, and Georgia, South Carolina and Louisiana would have over 10 percent of their population at risk by 2100 under some flood models.
