Pine Beetles don’t stick around on slippery bark, says CU-Boulder study

Mountain Pine Beetle

In the online journal Functional Ecology, Doctoral student Scott Ferrenberg and Professor Jeff Mitton of University of Colorado, Boulder describe how they conducted field surveys to determine if mountain pine beetles can successfully attack limber pines with smooth versus rough bark. Scott, who led the study, said he first began to suspect that bark texture might affect the survival of trees while he and Dr. Mitton, a professor of ecology and evolutionary biology, were walking through a stand … [Continue reading]

Dr. Konrad Steffen and James Hansen Offer Evidence for a Disruptive Call to Action

Konrad Steffen photo

A paper by James Hansen and 17 scientific colleagues includes the work of CU-Boulder Professor Emeritus of Geography, Konrad Steffen. “Assessing Dangerous Climate Change: Required Reduction of Carbon Emissions to Protect Young People, Future Generations and Nature” calls for cohesive, unified action to reduce fossil fuel emissions to pre-Industrial Era levels. The paper details the need for a multi-disciplinary approach to reducing carbon emissions. PLOS ONE, as publishers of the paper, … [Continue reading]

New study: Dust, warming portend dry future for the Colorado River

dust

Reducing the amount of desert dust swept onto snowy Rocky Mountain peaks could help Western water managers deal with the challenges of a warmer future, according to a new study led by researchers at NOAA’s Cooperative Institute for Research in Environmental Sciences (CIRES) at the CU - Boulder. With support from the CIRES Western Water Assessment (WWA) and NASA’s Interdisciplinary Science program, CIRES’ Jeffrey Deems and his colleagues examined the combined effects of regional warming and … [Continue reading]

Drought and the Spruce Bark Beetle: New CU-Boulder Study Makes the Connection

spruce bark beetle

Editor's note: The following article was submitted by CU-Boulder Geography Ph.D. student Sarah Hart. Periods of drought and warm temperatures, are responsible for periods of spruce beetle outbreak in Colorado, says a new University of Colorado Boulder-led study. A new study used tree-rings and documentary records of spruce beetle outbreak across much of the Rockies from the northern Front Range to Grand Mesa in southwestern Colorado over the past 300+ years to examine the climate variables … [Continue reading]

Polar Bears & Climate Change

Polar Bear and Cubs

New video of polar bear expert Dr. Ian Stirling's guest lecture at CU Boulder In Spring 2013, Dr. Ian Stirling visited CU-Boulder from Canada to speak about the affects of climate change on polar bears and their ecosystem. We recorded his lecture and are pleased to present the video here: … [Continue reading]

New video: Water-Energy Nexus & the Effects of Climate Change

water

Learn More About Climate is pleased to announce the newest in our series of videos featuring climate and natural resource experts from University of Colorado, Boulder. In "The Water-Energy Nexus and Effects of Climate Change," Western Water Assessment Director Kristen Averyt explores the "collision" of water supply vs. energy demands. The production of electricity consumes surprising amounts of water. Much of our water supply is "on call" for future use. … [Continue reading]

Like butter: CIRES study explains surprising acceleration of Greenland’s inland ice

Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, according to a new study by scientists at the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder. During the last decade, researchers have captured compelling evidence of accelerating ice flow at terminal regions, or “snouts,” of Greenland glaciers as they flow into the ocean along the … [Continue reading]

A new paper by researchers at Univ. of Washington, CIRES, and NOAA summarizes what is known about the future of the Colorado River

The Colorado River provides water for more than 30 million people in the U.S. West, so water managers have been eager to understand how climate change will affect the river’s flow. But scientific studies have produced an unsettling range of estimates, from a modest decrease of 6 percent by 2050 to a steep drop of 45 percent by then. A new paper by researchers at the University of Washington (UW), CIRES, NOAA and other institutions across the West investigates and explains why those … [Continue reading]
