Recent scientific flights above the Front Range will help scientists and policymakers cut unnecessary emissions, reduce greenhouse gases and help local residents breathe better. Participants include members of INSTAAR's Advanced Laser Technology for Atmospheric Research (ALTAiR) Laboratory
Armed with state-of-the-art equipment, researchers from the University of Colorado and University of Maryland spent a week flying above fracking sites in Weld County, Colorado to gather data surrounding possible methane leaks around fracking sites. This article includes a 2.5 minute video.
Abandoned hardrock mines and climate change cause metals and other elements to leach into streams. They also put rare earth elements into the water, as found by Garrett Rue and Diane McKnight in their new study.
A new study by Garrett Rue and Diane McKnight suggests lower stream flows, caused by climate change, as a primary culprit.
Acid rock and mine drainage into Western streams is a problem. Climate change is making it worse.
Too often, rising climate risk is conflated with rising CO2. That takes the heat off national and local leaders who can cut drivers of risk on the ground now. Andy Revkin collects in-depth perspective from scientists and others on the global risk of flooding, the inequities and policies that are driving up that risk, and what we can do to manage it. Revkin cites work that involved Albert Kettner and Bob Brakenridge of the DFO Flood Observatory.
Satellite imagery reveals how floods are changing and who’s most at risk. A new global floods database involved Bob Brakenridge and Albert Kettner of the DFO Flood Observatory.
Restoration of degraded drylands is urgently needed to mitigate climate change, reverse desertification and secure livelihoods for the two billion people who live in these areas, say an international group of ecologists who examined the success of seeding drylands with key native plant species. Their study is published today in Nature Ecology & Evolution. Lead author Nancy Shackelford started the project as a postdoc in Katie Suding's group.
The sudden and sustained rise in atmospheric levels of the potent greenhouse gas methane since 2007 has posed one of the most significant and pressing questions in climate research: Where is it coming from? Now a research team has tested the leading theories for surging methane levels by analyzing the stable carbon isotope ratios (δ13C-CH4) from methane captured in a large set of global air samples to determine if one of the theories is more feasible than the others.
Across the tundra, warming temperatures are causing plants to stay greener longer and flower earlier—and that could reshape life there, according to new research led by INSTAARs. The findings, published today in Nature Communications, synthesized 30 years of experimental warming data from 18 different tundra sites across the globe and found that not only are leaves coming out earlier and staying on the plants longer in this critically understudied biome, but their reproductive cycles are not responding in the same way. This change could not only have cascading effects through the ecosystem, but could also change the balance of carbon between the land and the atmosphere.
