Global warming disrupting Americans' lives, U.S. federal report warns

WASHINGTON -- Global warming is rapidly turning America into a stormy and dangerous place, with rising seas and disasters upending lives from flood-stricken Florida to the wildfire-ravaged West, according to a new U.S. federal scientific report.
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 that warming and all-too-wild weather are changing daily lives, 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. "It's a good news story about the many opportunities to take cost-effective actions to reduce the damage," said White House science adviser John Holdren.
He called the report, the third edition of a congressionally mandated study, "the loudest and clearest alarm bell to date signalling the need to take urgent action." Later this summer, the Obama administration plans to propose new and controversial regulations restricting gases that come from existing coal-fired power plants.
Some fossil energy groups, conservative think tanks and Republican senators immediately assailed the report as "alarmist." Senate Republican leader Mitch McConnell of Kentucky said President Barack Obama was likely to "use the platform to renew his call for a national energy tax. And I'm sure he'll get loud cheers from liberal elites -- from the kind of people who leave a giant carbon footprint and then lecture everybody else about low-flow toilets.
Republican Sen. David Vitter of Louisiana said the report was supposed to be scientific but "it's more of a political one used to justify government overreach."
The report -- which is full of figures, charts and other research-generated graphics -- includes 3,096 footnotes to other mostly peer-reviewed research. It was written by more than 250 scientists and government officials, starting in 2012. A draft was released in January 2013, but this version has been reviewed by more scientists, including twice by the National Academy of Science which called it "reasonable," and has had public comment. It is written in a bit more simple language so people can realize "that there's a new source of risk in their lives," said lead author Gary Yohe of Wesleyan University in Connecticut.
Environmental groups praised the report. "If we don't slam the brakes on the carbon pollution driving climate change, we're dooming ourselves and our children to more intense heat waves, destructive floods and storms and surging sea levels," said Frances Beinecke, president of the Natural Resources Defence Council.
Scientists and the White House called it 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.
"All Americans will find things that matter to them in this report," said scientist Jerry Melillo of the Marine Biological Laboratory, who chaired the science committee that wrote the report. "For decades we've been collecting the dots about climate change, now we're connecting those dots."
In a White House conference call with reporters, National Climatic Data Center Director Tom Karl said his two biggest concerns were flooding from sea level rise on the U.S. coastlines -- especially for the low-lying cities of Miami, Norfolk, Virginia, and Portsmouth, New Hampshire -- and drought, heat waves and prolonged fire seasons in the Southwest.
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.
