In a new book, University of Washington paleontologist Peter Ward suggests that Earth is ultimately inhospitable to life, and that life itself might be the primary reason. Rather than the nurturing idea of the Gaia hypothesis, he invokes the darker Medea from Greek mythology.
Forecasts of polar bear populations and their likely responses to climate change have been strengthened by a new publication that refutes criticisms of the scientific basis for listing the polar bear under the Endangered Species Act.
Some Michigan mammal species are rapidly expanding their ranges northward, apparently in response to climate change, a new study shows. In the process, these historically southern species are replacing their northern counterparts.

There has been recent disagreement about the snowpack decline in the Cascade Mountains of the Pacific Northwest, but new research leaves little doubt that a warmer climate has a significant effect on the snowpack, even if other factors keep year-to-year measurements close to normal for a period of years.
Earth's earliest ice age may have been due to the rise of oxygen in Earth's atmosphere, which consumed atmospheric greenhouse gases and chilled the earth. University of Maryland geologist Alan J. Kaufman and an international team of scientists uncovered evidence that the oxygenation of Earth's atmosphere coincided with the first global ice age.

An international team of researchers working under the auspices of the Integrated Ocean Drilling Program launched the New Jersey Shallow Shelf Expedition this morning in the early hours, taking advantage of the high tide to sail to the continental shelf just off the New Jersey shore. There, they will conduct coring operations to collect geological sediments that will inform them about Earth cycles that relate to sea level change, the mechanisms that force it, and that have impacted the geography of the shoreline over time.
The University of Washington has surpassed its own world record for operating a glider under the ice, this time by successfully operating one of its seagliders for six months as it made round trips hundreds of miles in length under the ice at Davis Strait.
A recent article published in the Journal of Environmental Quality examines the effectiveness of utilizing cover soil as a way to reduce methane emissions from landfills. The study suggests that the fraction of methane oxidized by the soil, a process which allows soil bacteria to consume the greenhouse gas, is greater than previous default value used by researchers.

Chicago and other cities have adopted green initiatives designed to foster more investment in local and regional agriculture. City officials and citizens alike often assume that by doing so they can help soften climate change by cutting greenhouse-gas emissions. But it's not that simple.
The impact of global warming can be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, according to an NCAR-led study. The most dangerous potential aspects of climate change, including massive losses of Arctic ice and significant sea-level rise, could be partially avoided.

EPA is expected to declare its authority to hold polluters accountable under the Clean Air Act.
Top international climate scientists are meeting this week at the University of Maryland laying the groundwork for improved regionalized climate change forecasts and for the advanced computing models needed to make these projections, says chair and host, Antonio Busalacchi. It's the first time in a decade that a U.S. scientist has led the Joint Scientific Committee of the World Climate Research Programme.
New research helps scientists predict wildfire hotspots as global warming changes weather patterns.
The "˜carbon sink' in the North Atlantic is the primary gate for carbon dioxide (CO2) entering the global ocean and stores it for about 1500 years. The oceans have removed nearly 30 per cent of anthropogenic (man-made) emissions over the last 250 years. However, several recent studies show a dramatic decline in the North Atlantic Ocean's carbon sink.
A nearly ice-free Arctic Ocean in the summer may happen three times sooner than scientists have estimated. New research says the Arctic might lose most of its ice cover in summer in as few as 30 years instead of the end of the century.
Scripps researchers contribute to assessment concluding that loss of agricultural land, increased risk of wildfires among potential outcomes.
Nights are getting hotter among cities in east Africa as growing populations change sensitive local weather patterns, according to research at The University of Alabama in Huntsville.
A study conducted at the University of Notre Dame revealed that nitrous oxide, a potent greenhouse gas, is frequently produced in the sediments of small streams and that production rates were best explained by stream water nitrate concentrations. These concentrations are often the result of runoff from agricultural soils, where it is well established that a high presence of nitrates can stimulate nitrous oxide production.
A review article published in Environmental Health Perspectives suggests that increasing changes in global climate and oscillations in atmospheric temperatures may shift the use and spread of agricultural chemicals and pathogens, resulting in potentially harmful human exposures. Although the authors focused their review on the U.K. agricultural environment, they wrote that some of their conclusions are applicable and relevant to other countries as well as to sectors other than agriculture.
The recent warming trend in the Atlantic Ocean is largely due to reductions in airborne dust and volcanic emissions during the past 30 years, according to a new study.
Recent scientific studies document "early warning signs" that many natural systems are approaching irreversible changes driven by global warming. Overwhelming scientific evidence supports reducing carbon pollution that causes global warming as much as possible and as quickly as possible.

Fueled by the slogan "Turn your lights off, turn the Earth on!" Misericordia University's new environmentally-focused student group, Cougars for Change, is leading campus efforts to participate in a world-wide initiative to draw attention to responsible energy use and global warming.
Calling New Orleans "the canary in the global warming coal mine," two Tulane professors say the Crescent City must embrace unconventional thinking in order to recover in a sustainable way from Hurricane Katrina while withstanding a continual threat from rising sea levels, diminishing wetlands and future storms. They stress that the No. 1 priority for Louisiana should be to combat global warming and accelerated sea-level rise.
Volunteers across the country are welcoming spring by taking part in a nationwide initiative to track climate change by recording the timing of flowers and foliage. Project BudBurst, operated by the University Corporation for Atmospheric Research and partners, has amassed thousands of observations from students, gardeners, and other citizen scientists.

An overarching theme for the meeting is climate change, and technical sessions will highlight cutting-edge scientific research on a wide variety of topics.
Global warming is expected to cause the sea level along the northeastern U.S. coast to rise almost twice as fast as global sea levels during this century, putting New York City at greater risk for damage from hurricanes and winter storm surge, according to a new study led by a Florida State University researcher.
Large areas of much warmer than normal temperatures over Western Greenland, China and the Northern Pacific Ocean pushed the Northern Hemisphere's average temperature in February to the fifth highest level seen in the 30+ year satellite-based temperature record.
A University of Maryland-led team has compiled the first decades-long database of aerosol measurements over land, making possible new research into how air pollution changes affect climate change. The researchers show that clear sky visibility over land has decreased globally, indicative of increases in aerosols, or airborne pollution. Their findings are published in the March 13 issue of Science.
