On May 3, members of the U.S. House Committee on Science, Space, and Technology and Colorado congressional delegation joined leaders and scientists from CU �鶹ӰԺ, including INSTAAR Director Merritt Turetsky, to showcase university research and federal partnerships.

Keith Musselman was interviewed for this CBS Denver news story on the effects of climate change on deep snowpack.

As climate change fuels the spread of wildfires across the West, researchers want to know how the dual effect might disrupt water supplies. Noah Molotch is among those interviewed.

Researchers from Imperial College London have performed new measurements using data from INSTAAR's Stable Isotope Lab (Sylvia Englund Michel). They found London produces 30-35% more methane than previously thought. Previous estimates suggested 25% of London's methane is from natural gas leaks, but the new study says it's up to 85%.

A warmer, drier alpine is impeding water quality for streams and rivers used for snowmaking, like the Snake River that runs through Keystone. Diane McKnight is interviewed in this Colorado Sun story.

Because of climate change, the snowpack in the Western U.S. is already 20% less than it was in the 1950s, a volume of water that could fill Lake Mead, the largest reservoir in the country. By the end of the century, most years in the region could be nearly snowless. Keith Musselman is interviewed.

In coming decades, the shifting terrain that accompanies the warming of the permafrost caused by climate change will put most human-made structures in the Arctic at risk. Nearly 70 percent of the infrastructure in the Northern Hemisphere's permafrost regions—including at least 120,000 buildings and nearly 25,000 miles of roads—are located in areas with high potential for thaw of near-surface permafrost by 2050, according to new research. Quotes Merritt Turetsky: "I am writing a eulogy for the ecosystem that I love. The permafrost has been there for thousands of years in some places, and it will never come back."

Permafrost contains microbes, mammoths, and twice as much carbon as the atmosphere. What happens when it starts to thaw? Merritt Turetsky weighs in.

The ground, typically moist from snow this time of year, was dry and flammable as a result of unusually warm temperatures and a lack of precipitation in recent months, said experts including INSTAAR snow hydrologist Keith Musselman.

Redpolls, an Arctic-dwelling finch that flies south only sporadically, all share a characteristic red marking on their heads. But some redpolls are white with small bills, while others are larger and have whiter bills. Due to these differences, scientists initially thought that there were three different species of redpoll. However, new genetic research led by CU �鶹ӰԺ and including INSTAAR Scott Taylor has found that these apparently different species are in fact the same, but have a “supergene” that controls differences in morphology and plumage color.
