Amazonian drought conditions add carbon dioxide to the atmosphere

Amazon River through the rainforest

This article originally appeared on the University of Colorado Boulder website. As climates change, the lush tropical ecosystems of the Amazon Basin may release more of the greenhouse gas carbon dioxide into the atmosphere than they absorb, according to a new study published Feb. 6 in Nature. An international team of scientists found that the amount of yearly rainfall was the driving factor behind the amount of carbon dioxide (CO2) taken up and released from Amazonia in 2010 and 2011. During a wet year, the Amazon forests were roughly carbon-neutral: Forests “inhaled” more carbon … [Read more...]

Keeping up with CU-Boulder Researchers in Antarctica

CU-Boulder researchers in Antarctica

The University of Colorado Boulder has multiple research projects going on in Antarctica every year. Here's a look at what teams from the Cooperative Institute for Environmental Sciences and the Institute of Arctic and Alpine Research are up to this season. The McMurdo Dry Valleys--the largest relatively ice-free zone on the Antarctic continent--has been studied as part of the National Science Foundation's Long-Term Ecological Research Network since 1993. The principal investigator on the project is Outreach Award recipient Diane McKnight, a fellow at CU-Boulder's Institute of Arctic and … [Read more...]

Workshops and webinars for educators

Have you set your professional development goals for 2014? Here are some great workshops and events to start the year: Exploring the Aurora through Art and Writing Come learn about Space Weather and how it relates to Earth’s climate! This one-day workshop for elementary teachers and educators will explore the Sun-Earth connection, the role Earth’s magnetic field plays, and how space weather influences our planet in very real ways. This workshop will draw upon the Dancing Lights suite of standards-based activities. Materials for your classroom will be provided along with information about … [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...]
