Newswise — The U.S. Global Change Research Program released a long-awaited, comprehensive scientific assessment of climate change impacts in the United States. It presents the first region-by-region analysis of our vulnerability to climate change since 2001 and represents the best available climate science in the United States. The report outlines choices based on various global emissions scenarios including one that transitions the U.S. to a clean energy future versus business as usual reliance on fossil fuels.

Larry Schweiger, President and CEO of National Wildlife Federation, said:

"This report spells out a state of emergency in the U.S., one that demands immediate and decisive action. If we had an enemy threatening public health, damaging our water supplies, limiting our water and food supplies, and wreaking havoc on our coastal communities, there is no question we would demand our very best effort to fight back this enemy. Like Paul Revere, this report is shouting that the enemy is at our doorstep. The enemy is climate change.

"We must mobilize swiftly and decisively. Failing to act will mean more severe impacts to public health and safety, and more people, especially children, the elderly and the poor will suffer. Failing to act will put more of our natural resources and the public benefits they provide at risk.

"Now is the time to set America on a new energy path that combines clean energy incentives and firm limits on carbon pollution that causes global warming. The American Clean Energy and Security Act (ACES) gives the U.S. more than 30 new tools to confront the climate crisis and advance the clean energy economy. There is no time for delay."
