Working to keep the West special

RMCO Reports

RMCO has written and released in partnership with other organizations14 reports detailing the effects of climate disruption on the West and across the country.

Extreme Heat in Fort Collins. A RMCO report for the City of Fort Collins, January 2014. The report documents increases in hot days and heat waves in Fort Collins since 1961. Annual rates of both single days 95 degrees or hotter and three straight days of 90 degrees or hotter have tripled so far this century, compared to 1961-1999 rates. New climate projections show large increases in these frequencies in the future, especially if emissions continue at a relatively high rate. With medium-high future emissions, for example, 95-degree days could occur six times as often as the historic rate by mid-century, and 13 times as often by the end of the century.

Atlantic National Seashores in Peril: The Threats of Climate Disruption. A RMCO-Natural Resources Defense Council report, August 2012. The report is on the effects of climate change on the seven national seashores on the U.S. Atlantic Coast: Cape Cod (in Massachusetts), Fire Island (New York), Assateague Island (Maryland and Virginia), Cape Hatteras (North Carolina), Cape Lookout (North Carolina), Cumberland Island (Georgia), and Canaveral (Florida) national seashores. The report includes new maps showing that for five of them, most seashore lands are less than 3.3 feet above the current sea level, and so are at risk of being submerged by a higher sea and before then of having roads and other infrastructure destroyed, lands eroded, and barrier islands broken into pieces by stronger coastal storms and rising waters.

Doubled Trouble: More Midwestern Extreme Storms. A RMCO-Natural Resources Defense Council report, May 2012. The report documents how much heavy precipitation has increased in the Midwest and sheds new light on the devastating and costly floods that have hammered the region, especially in recent years. New RMCO analysis of a half century of precipitation data across the Midwest, defined as Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, and Wisconsin, indicates the region has had an increasing number of large storms since 1961. The largest of storms—those of three inches or more of precipitation in a single day—have increased the most, with their annual frequency more than doubling over the past 51 years.

Greater Yellowstone in Peril: The Threats of Climate Disruption. A RMCO-Greater Yellowstone Coalition report, September 2011. The report highlights the particular threats that a changed climate poses to the Greater Yellowstone Ecosystem—Yellowstone and Grand Teton national parks, parts of six national forests, and more. New climate projections obtained for the report indicate that, under a medium-high emissions rate of heat-trapping gases, summers in Yellowstone NP on average could become slightly hotter than recent summers in Culver City in the Los Angeles area.

Great Lakes National Parks in Peril: The Threats of Climate Disruption. A RMCO-Natural Resources Defense Council report, July 2011. The report documents the vulnerabilities to human-caused climate change of Indiana Dunes National Lakeshore, Indiana; Sleeping Bear Dunes National Lakeshore, Pictured Rocks National Lakeshore, and Isle Royale National Park, Michigan; and Apostle Islands National Lakeshore, Wisconsin. New climate projections done for the report show that summers in Indiana Dunes could become as hot as those of Gainesville, Florida, have been, if future emissions of heat-trapping pollution are at medium-high levels.

Acadia National Park in Peril: The Threats of Climate Disruption. A RMCO-Natural Resources Defense Council report, November 2010. The report details how a climate altered by human activities may affect the first national park east of the Mississippi River. New climate projections done for the report show that before the end of the century Acadia could become as hot as Atlantic City, New Jersey, historically has been.

California's National Parks in Peril: The Threats of Climate Disruption. A RMCO-Natural Resources Defense Council report, October 2010.The report details how climate disruption could affect ten national parks in California. If we do not limit emissions of heat-trapping gases, before the end of the century Yosemite National Park would become hotter than Sacramento historically has been. Temperature increases of this magnitude would have far-reaching impacts on Yosemite, Point Reyes National Seashore, and Sequoia, Kings Canyon, Joshua Tree, Death Valley, and Redwood national parks, and more of California's most special places.

Virginia Special Places in Peril: Jamestown, Chincoteague, and Shenandoah Threatened by Climate Disruption. A RMCO-Natural Resources Defense Council report, September 2010. The report details how Jamestown, the site of the first permanent European settlement in what became the American colonies and the United States, may be lost to rising waters of the James River, pushed higher by rising seas and tidal waters. Likely climate-change Impacts to Chincoteague National Wildlife Refuge and Shenandoah National Park are documented, too.

Glacier National Park in Peril: The Threats of Climate Disruption. A RMCO-NRDC report, April 2010, documenting how an altered climate puts at risk both Glacier National Park's spectacular resources and the tourism -- a mainstay of Montana's economy -- attracted by the park's scenery, wildlife, and other resources. National Parks in Peril: The Threats of Climate Disruption. A RMCO-Natural Resources Defense Council report, October 2009. This report identifies 25 national parks across the country most threatened by a changing climate and documents 11 different types of risks to our parks that are already underway or could result from emissions of heat-trapping pollution. The report also includes 32 recommendations for actions specific to our national parks to address climate change and its impacts.

National Parks In Peril: The Threats of Climate Disruption. A RMCO-NRDC report, October 2009, documenting that climate disruption is the greatest threat ever to America's national parks and identifying 25 parks most at risk. It also recommends actions to protect their parks and their resources and also to reduce the emissions that put them at risk.

Hotter and Drier: The West's Changed Climate. A RMCO-Natural Resources Defense Council report, March 2008. This report documented that the West has gotten hotter at a faster rate than the planet as a whole. Across the 11 states of the American West, temperatures in 2003-2007 were 1.7°F higher than the 20th-century average for the region. By contrast, global temperatures in that five-year period were 1.0°F hotter than the planet's 20th-century average. The report also presents similar data for each of the 11 western states, and documents other ways in which the West's climate is already changing and the impacts of those changes. See also a summary of that report, the news release announcing it, a copy of key figures from the report, and a PowerPoint slide of those figures. The figures and slide may be used freely, so long as credit is given.

Losing Ground: Western National Parks Endangered by Climate Disruption. A RMCO-Natural Resources Defense Council report, July 2006. This report identifies 12 national parks in the western states most vulnerable to a changing climate.

Less Snow, Less Water: Climate Disruption in the West. A RMCO-Clear the Air report, September 2005. This report pulls together evidence of how an altered climate may affect the arid and semi-arid West's scarce snow and water resources. The report includes a new analysis of declines in snowpacks in the Colorado, Columbia, Missouri, and Rio Grande river basins.

All these reports have been widely covered in the news media. For links to particular news articles, see the section of this website on RMCO in the News, where the articles are listed chronologically near the dates of release of the reports.
