New report highlights how climate change may affect water in Colorado

Report: Climate Change in Colorado

As Colorado’s climate continues to warm, those who manage or use water in the state will likely face significant changes in water supply and demand, according to a new report on state climate change released today by the Western Water Assessment and the Colorado Water Conservation Board. Rising temperatures will tend to reduce the amount of water in many of Colorado’s streams and rivers, melt mountain snowpack earlier in the spring, and increase the water needed by thirsty crops and cities, according to the new report, “Climate Change in Colorado: A Synthesis to Support Water Resources … [Read more...]

CU climate scientists available to speak on National Climate Assessment (NCA)

New from Colorado.EDU: In 2012, temperatures at the summit of Greenland rose above freezing for the first time since 1889, raising questions about what led to the unusual melt episode. Now, a new analysis led by the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder shows that some of the same weather and climate factors were at play in both 1889 and 2012: heat waves thousands of miles upwind in North America, higher-than-average ocean surface temperatures south of Greenland and atmospheric rivers of warm, moist air that streamed toward … [Read more...]

Five questions for Climate Scientist James White

5q-jameswhite_top_320x100

This interview, conducted by Cynthis Pasquale, originally appeared in the University of Colorado CU Connections website. You can watch videos featuring Professor White on the Climate & Weather section of Learn More About Climate. Humans and ecosystems can adapt to a slowly changing climate, but what happens when these changes happen abruptly? “When it comes to climate change, speed kills,” says James White, a Fellow and Director of INSTAAR (Institute of Arctic and Alpine Research) and a professor of geological sciences at the University of Colorado Boulder. White headed a panel of the … [Read more...]

New Report on Abrupt Climate Change Calls for Increased Monitoring and Early Warning System

West Antarctica Ice Sheet

A new National Academy of Science report on climate change has just been made available from its National Research Council, chaired by Professor James White of CU-Boulder’s Institute of Arctic and Alpine Research. A video replay of the press briefing webcast is now available. Read or download a pdf of the the complete report or view the summary here: Summary: Abrupt Impacts of Climate Change The report, “Abrupt Impacts of Climate Change: Anticipating Surprises,” draws upon recent research to adjust the timeframe within which certain climate change impacts may happen. It emphasizes … [Read more...]

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 dust on the Colorado River, which is fed primarily by snowmelt. During recent years, desert dust … [Read more...]
