Contrary to conventional belief, as the climate warms and growing seasons lengthen subalpine forests are likely to soak up less carbon dioxide, according to a new University of Colorado at Boulder study. As a result, more of the greenhouse gas will be left to concentrate in the atmosphere. "Our findings contradict studies of other ecosystems that conclude longer growing seasons actually increase plant carbon uptake," said Jia Hu, who conducted the research as a graduate student in...

It's no secret that the emissions leaving a car tailpipe or factory smokestack affect climate and air quality. Even trees release chemicals that influence the atmosphere. But until now, scientists have struggled to know where these organic molecules go and what happens to them once they leave their source, leading to models for predicting climate and air quality that are incomplete or less than accurate. A major collaborative effort of more than 60 scientists led by Jose-Luis Jimenez, an...

Nine research challenges and four research initiatives that are poised to advance the study of how Earth's landscapes change were unveiled today in a new report by the National Research Council. These challenges and initiatives could open the path to resolving environmental issues, from coastal erosion to landslides, by helping predict how processes such as wind, ice, water, tectonics, and living organisms drive changes in the Earth's surface. The development of new analytic and computing...

Researchers say regional surface temperatures can be affected by land use, suggesting that local and regional strategies, such as creating green spaces and buffer zones in and around urban areas, could be a tool in addressing climate change. A study by researchers from Purdue University and the universities of Colorado and Maryland concluded that greener land cover contributes to cooler temperatures, and almost any other change leads to warmer temperatures. The study, published on line and...

Remains On Downward Trend Despite a slight recovery in summer Arctic sea ice in 2009 from record-setting low years in 2007 and 2008, the sea ice extent remains significantly below previous years and remains on a trend leading toward ice-free Arctic summers, according to the University of Colorado at Boulder's National Snow and Ice Data Center. According to the CU-Boulder center, the 2009 minimum sea ice extent was the third lowest since satellite record-keeping began in 1979. The past five...

CU-Boulder's Snow and Ice Data Center analysis shows negative summertime ice trend continues The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center. While this year's September minimum extent was greater than each of the past two record-setting and near-record-setting low years, it is still...

As the West warms, a drier Colorado River system could see as much as a one-in-two chance of fully depleting all of its reservoir storage by mid-century assuming current management practices continue on course, according to a new University of Colorado at Boulder study. The study, in press in the American Geophysical Union journal, Water Resources Research, looked at the effects of a range of reductions in Colorado River stream flow on future reservoir levels and the implications of different...

Researchers trace a problem with a key climate model to its hyrdrology scheme and find a simpler scheme keeps simulations in line with real-world observations Imagine a climate model as a black box. You put something in, you get something out. But what happens when the output is completely unexpected? "If you don't get the results you expect, that's when you start to ask why," said climate modeler Peter Lawrence from the University of Colorado at Boulder's Cooperative Institute for Research...

Climate scientists are continuing to uncover new revelations about the impact of man-made global warming on the Earth's future, but many face frustration when it comes to informing the world's population of the urgency of such findings. "Science is exciting when you make such findings," Konrad Steffen, who heads the Cooperative Institute for Research in Environmental Sciences (CIRES) in Boulder, Colorado, told AFP. "But if you stop and look at the implications of what is coming down the road...

A proposed method of injecting sulfate particles into the stratosphere in order to fight the effects of global warming, would have a drastic impact on Earth's protective ozone layer, researchers said in a new study.Simone Tilmes of the National Center for Atmospheric Research (NCAR) and colleagues conducted the study, which was published Thursday in Science Express.Researchers looked at the possible effects of "geoengineering" methods of cancelling out the impacts of global warming. One of...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
