WASHINGTON — Global warming is rapidly turning America the beautiful into America the stormy, sneezy and dangerous, according to a new federal scientific report. And those shining seas? Rising and costly, the report says.
Climate change’s assorted harms “are expected to become increasingly disruptive across the nation throughout this century and beyond,” the National Climate Assessment concluded Tuesday. The report emphasizes how warming and its all-too-wild weather are changing daily lives, even using the phrase “climate disruption” as another way of saying global warming.
Still, it’s not too late to prevent the worst of climate change, says the 840-page report, which the White House is highlighting as it tries to jump-start often stalled efforts to curb heat-trapping gases.
However, if the nation and the world don’t change the way they use energy, “we’re still on the pathway to more damage and danger of the type that are described in great detail in the rest of this report,” said study co-author Henry Jacoby, co-director of the Joint Program on the Science and Policy of Global Change at the Massachusetts Institute of Technology. Jacoby, other scientists and White House officials said this is the most detailed and U.S.-focused scientific report on global warming.
“Climate change, once considered an issue for a distant future, has moved firmly into the present,” the report says. “Corn producers in Iowa, oyster growers in Washington state and maple syrup producers in Vermont are all observing climate-related changes that are outside of recent experience.”
The report looks at regional and state-level effects of global warming, compared with recent reports from the United Nations that lumped all of North America together. A draft of the report was released in January 2013, but this version has been reviewed by more scientists, the National Academy of Science and 13 government agencies and had public comment. It is written in a bit more simple language so people could realize “that there’s a new source of risk in their lives,” said study lead author Gary Yohe of Wesleyan University in Connecticut.
Even though the nation’s average temperature has risen by as much as 1.9 degrees since record keeping began in 1895, it’s in the big, wild weather where the average person feels climate change the most, said co-author Katharine Hayhoe, a Texas Tech University climate scientist. Extreme weather like droughts, storms and heat waves hit us in the pocketbooks and can be seen by our own eyes, she said.
And it’s happening a lot more often lately.
