Reply To: Global warming is well underway

Climate change is already reshaping the United States, according to a new federal report that predicts global warming could have serious consequences for how Americans live and work.

Hotter temperatures, an increase in heavy downpours, and rising sea levels are among the effects of "unequivocal" warming, concludes the report by the U.S. Global Change Research Program. Winters are now shorter and warmer than they were 30 years ago, with the largest temperature rise — more than 7 degrees Fahrenheit — observed in the Midwest and northern Great Plains.

The changes are already affecting human health, agriculture, coastal areas, transportation and water supplies. And climate change will intensify over the next century even with significant action to limit greenhouse gas emissions from human activities.
