Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth's climate changes, further accelerating global warming, a new computer modeling study indicates.

Mount Sinai School of Medicine researchers have found that climate change may lead to more asthma-related health problems in children, and more emergency room (ER) visits in the next decade.

Conservationists may need to change their approach to protecting animals and plants from extinction if they are to successfully shield key species and habitats from the effects of global climate change, according to a new review in the journal Science.

Chemical changes in tree leaves subjected to warmer, drier conditions that could result from climate change may reduce the availability of soil nutrients, according to a Purdue University study.

Himalayan villagers have won the backing of climate science for their suspicions that snow cover, water resources and the ecosystem are changing in their region, a study published Wednesday said.

Psychologists are offering new insight and solutions to help counter climate change, while helping people cope with the environmental, economic and health impacts already taking a toll on people's lives, according to a special issue of American Psychologist, the American Psychological Association's flagship journal.

Precipitation and runoff in California's major river basin will not fall dramatically with climate change, according to a new federal study that shows rising temperatures will have an uneven effect on the West's water supplies.

Janet K. Swim, professor of psychology, Penn State, and her colleagues report that growing consumption and growing population are two significant contributors to human impact on the environment. Both substantially increase carbon dioxide levels in the atmosphere, the researchers report in a special issue of American Psychologist that focuses on how psychology contributes to understanding and addressing global climate change. "Engaging in one type of environmentally friendly behavior can predispose one to engage in similar behaviors, inhibit other behaviors, or even increase environmentally harmful behaviors," said Swim.

"Climate change caused by global warming is slowing down world economic output by 1.6 percent a year and will lead to a doubling of costs in the next two decades, a major new report said."

"The projected snow loss, a result of climate change, could get even worse by the end of the 21st century, depending on how the world reacts. Sustained action to reduce global greenhouse gas emissions could keep annual average snowfall levels steady after mid-century, but if emissions continue unabated, the study predicts that snowfall in Southern California mountains will be two-thirds less by the year 2100 than it was in the years leading up to 2000."

The threat to climate change posed by thawing permafrost, which could release stocks of stored carbon, is greater than estimated, a group of scientists said on Wednesday.

Encouraging climate-smart agriculture can lead to climate change adaptation practices in a partnership where the farmer's needs are addressed.

A European drive to forge a legally-binding deal on climate change by 2015 that would include all major carbon polluters is "too much", a senior Chinese negotiator said at UN talks here.

The Belchatow power plant is seen in September 2011 in Poland. The world has just five years to avoid being trapped in a scenario of perilous climate change and extreme weather events, the International Energy Agency (IEA) warned

Americans' belief in global warming is on the rise, along with temperatures and surprising weather changes, according to a new university poll.

A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows a link between large dust storms on Iceland and glacial melting. The dust is both accelerating glacial melting and contributing important nutrients to the surrounding North Atlantic Ocean. The results provide new insights on the role of dust in climate change and high-latitude ocean ecosystems.

A new study from the University of Reading highlights how climate change is having a detrimental effect on an endangered tropical bird population.

If you thought 2010 was disruptive, wait until 2011. This year we saw major game-changers emerge -- the iPad, a flurry of mobile apps, the rise of social commerce, C-Suite fixation on enterprise social-media -- and more. This coming year we'll see even more dramatic change. Keep your eyes on the following

Much more is needed than just correct information if we want people to pull together to mitigate climate change.

A new study has found that an emerging tool for combating climate change may cause less harm to some soil animals than initial studies suggested.
