In the first half of the nineteenth century, American settlers pushed westward into the Great Plains, lured to the prairies by the agricultural promise of their dark, rich soils.
Within a century, America’s tallgrass prairies—which once stretched across more than 150 million acres, from Minnesota south to Texas and from Illinois west to Nebraska—had all but vanished under settlers’ plows. The demise of the tallgrass prairie also meant the demise of dozens of species of grasses that could grow to the height of a man, hundreds of species of flowers and herds of roaming bison.
Two CU-Boulder environmental researchers -- Kevin J. Krizek and Maxwell Boykoff -- have been named Leopold Leadership Fellows for 2013 in recognition of their outstanding leadership abilities and desire to communicate scientific issues beyond academic audiences.
A new study by an international team of scientists analyzing ice cores from the Greenland ice sheet going back in time more than 100,000 years indicates the last interglacial period may be a good analog for where the planet is headed in terms of increasing greenhouse gases and rising temperatures.
A human induced problem for the California condor begets the need for ongoing human intervention to prevent extinction, according to a new study led by the University of California, Santa Cruz, and involving the University of Colorado Boulder.
Clara Boland didn’t fully appreciate coal’s role in her life until she did some digging. That meant going to Paonia, a small town in Western Colorado, which has mined coal for more than a century.
Boland’s aim was to create a short documentary film for a course on conveying climate science through film. Her journey began in Boulder, where young people called coal “yesterday’s fuel,” dirty and toxic.
Why has the world been unable to address global warming? Science policy expert Roger Pielke, Jr., CU-Boulder professor of environmental studies, says it's not the fault of those who reject the Kyoto Protocol, but those who support it and the magical thinking that the agreement represents.
In his book The Climate Fix: What Scientists and Politicians Won’t Tell You About Global Warming, Pielke offers a way to repair climate policy, shifting the debate away from meaningless targets and toward a revolution in how the world's economy is powered.
