A mobile suite of climate monitoring equipment has moved to Niger to take cloud and aerosol measurements for a year. (Sandia National Laboratories press release)

A study of methane-producing Archaea at the base of Greenland’s ice sheet indicates that about one microbe per cubic centimeter underground could produce enough methane to maintain observed levels in the Martian atmosphere. (University of California-Berkeley press release)

The second satellite in the Meteosat Second Generation family is due to be launched on December 21 from Kourou, French Guiana. (European Space Agency press release)

Trees in the Amazon tropical forests are much older than previously believed, surprising a team of researchers studying tree growth in the world’s largest tropical region. (University of California-Irvine press release)

Glaciers, rivers and shifting tectonic plates have shaped mountains over millions of years, but earth scientists have struggled to understand the relative roles of these forces and the rates at which they work--until now. (University of Michigan press release)

A researcher is using mathematical theory to build a model of the Madden-Julian Oscillation, a tropical weather pattern that influences drought and rainfall in the western United States. (University of California-Davis press release)

New simulations of the 21st-century climate show human-produced changes in land cover could produce additional warming in the Amazon region comparable to that caused by greenhouse gases, while counteracting greenhouse warming by 25% to 50% in some mid-latitude areas. (National Center for Atmospheric Research press release)

Forest productivity may be significantly greater in an atmosphere enriched with carbon dioxide, according to findings that challenge recent reports that question the importance of carbon dioxide fertilization. (Oak Ridge National Laboratory press release)

Alaska's rapidly disintegrating Columbia Glacier, which has shrunk in length by nine miles since 1980, has reached the mid-point of its projected retreat, according to a new study. (University of Colorado at Boulder press release)

Not only is the air around the world's highest mountains thin, but it's thick with ozone, says a new study. (University of Toronto press release)

Absent any climate policy, scientists have found a 70 percent chance of shutting down the thermohaline circulation in the North Atlantic Ocean over the next 200 years, with a 45 percent probability of occurring this century. (University of Illinois-Urbana/Champaign press release)

New research suggests mercury can be carried long distances in the atmosphere, combining with other airborne chemicals to form compounds that are much more water-soluble and so more easily removed from the air in rainfall. (University of Washington press release)

If humans continue to use fossil fuels in a business as usual manner for the next several centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar 14.5 degrees warmer than current day. (Lawrence Livermore National Laboratory press release)

Growing a forest might sound like a good idea to combat global warming since trees draw carbon dioxide from the air and release cool water from their leaves--but they also absorb sunlight, warming the air in the process. (Carnegie Institution press release)

Tropical areas of South and Central America such as the Amazon rainforest are home to some 7,500 species of butterfly compared with only around 65 species in Britain, but scientists have ruled out the common theory that attributed this richness of wildlife to climate change. (University College London press release)

A new study suggests researchers need to dig to deeper into soils to harvest enough data that would make climate models more fruitful. (University of Illinois-Urbana/Champaign press release)

Scientists studying the effects of carbon on climate warming are very likely underestimating, by a vast amount, how much soil carbon is available in the high Arctic to be released into the atmosphere, new research shows. (University of Washington press release)

Research shows that the combined effects of atmospheric brown clouds and greenhouse gases negatively affect growing conditions for rice in India. (University of California-Berkeley press release)

The University of California-Davis will study how air pollution harms human health by triggering premature deaths, sending more sick people to the hospital and damaging children's lungs. (University of California-Davis press release)

Tropical ocean temperatures and land vegetation have an important effect on African monsoon systems and are critical to sustaining agriculture in equatorial Africa, say researchers. (University of California-Santa Barbara press release)

Since the Industrial Revolution, levels of carbon dioxide---a major contributor to the greenhouse effect---have been on the rise, and now researchers have found that a class of materials invented and developed at the University of Michigan can store vast amounts of the gas. (University of Michigan press release)

The growth of Chinese imports in the U.S. economy boosted the total emissions of carbon dioxide from the two countries by over 700 million metric tons between 1997 and 2003, according to a new study. (National Center for Atmospheric Research press release)
