New Video Explores Arctic Sea Ice, Variability, and Climate Models


The heartbeat of the arctic impacts climate worldwide. Join Jen Kay, CU-Boulder assistant professor of atmospheric and oceanic sciences and Cooperative Institute for Research in Environmental Sciences fellow, to learn about the “heartbeat”— or melt cycles of the arctic — climate modeling, and climate change in the new video, Arctic Sea Ice, Variability, and Climate Models: Kay studies cloud processes, polar climate, recent and projected Arctic sea ice loss, and evaluation and improvement of climate models. In this video she briefly explains how climate models work and the important role … [Read more...]

Belief in Climate Change Not Linked to Wildfire Mitigation Actions


People who believe that climate change is increasing the risk of devastating wildfires in Colorado are no more likely to take mitigation actions to protect their property, a new study led by researchers at the University of Colorado Boulder and the U.S. Forest Service has found. The study, which was recently published in the journal Environmental Hazards, examined the role that climate change beliefs play in a homeowner’s choice to undertake risk mitigation activities such as installing a fire-resistant roof to reduce the ignitability of their home or thinning surrounding vegetation that … [Read more...]

High School Class Builds Snow Depth Sensor: How You Can Too

Snow Sensor

Students at Pagosa Springs High School have great opportunities to collect authentic environmental data in their classes, and they have recently expanded their capacity to monitor snow depth thanks to a resourceful peer, Connor Burkesmith. With support from Learn More About Climate and technical support from Andrew Wickert, an alumnus of the CU-Boulder Institute of Arctic and Alpine Research, Burkesmith built a snow sensor as part of his independent study project to collect low-elevation snow depth data near downtown Pagosa Springs. Wickert developed the sensor, called an ALog Data Logger, … [Read more...]

Teachers Invited to Power of Water Workshops

Water workshops

Teachers are invited to join the Cooperative Institute for Research in Environmental Sciences for workshops in July and August that address the power of water. Learn how water impacted stream ecosystems and geomorphology as a result of the great flood of 2013 and the ways in which water and invasive species can affect stream flows and stream structure. Hear from CU-Boulder scientists and learn about activities your students can do related to their research. These workshops are geared toward secondary science teachers but are open to all K-12 teachers. Sign up for one or both workshops, but … [Read more...]

Mountains Warming Faster than Expected as Climate Changes, Scientists Report


An international team of scientists is calling for urgent and rigorous monitoring of temperature patterns in mountain regions after compiling evidence that high elevations could be warming faster than previously thought. Without substantially better information, people risk underestimating the severity of a number of already looming environmental challenges, including water shortages and the possible extinction of some alpine flora and fauna, according to the research team, which includes Henry Diaz and Imtiaz Rangwala from CIRES, the Cooperative Institute for Research in Environmental … [Read more...]

Arctic Sea Ice Loss 
Expected to be Bumpy in the Short Term


Arctic sea ice extent plunged precipitously from 2001 to 2007, then it barely budged between 2007 and 2013. Even in a warming world, researchers can expect such unusual periods of no change—and rapid change—at the world’s northern reaches, according to a new paper. “Human-caused global warming is melting Arctic sea ice over the long term, but the Arctic is a variable place, said Jennifer Kay, a fellow of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder and co-author of the new analysis in Nature Climate Change. Natural ups and downs … [Read more...]

New report charts Colorado’s climate change

Fire Drop

Sea-level rise may not be eating away at Colorado’s borders, but climate change exposes other critical vulnerabilities in the state, according to a new report. Rising temperatures likely will take a toll on cattle and crops, for example, and could more often leave junior water rights holders with little water and few options. The new report, “The Colorado Climate Change Vulnerability Study,” was commissioned by the Colorado Energy Office in accordance with the Colorado Legislature’s House Bill 13-1293, according to a CU-Boulder news release. It’s a sector-by-sector analysis of the … [Read more...]

Climate Change heat map

The following reports published during 2014 have been instrumental in guiding the conversation, planning and actions of communities, governments and institutions that are concerned about climate change. These are the top 10 most-viewed reports for 2014 on the Learn More About Climate SlideShare channel. 1. World Economic Forum: Global Risks 2014 The World Economic Forum lists "failure of climate change mitigation and adaptation" as #5 on its list of Ten Global Risks of Highest Concern in 2014. The Global Risks report is widely recognized as one of the world’s leading publications on … [Read more...]

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...]
