Arctic seabirds adapt to climate changeScienceDaily.com | 16 May 2012
The planet is warming up, especially at the poles. How do organisms react to this rise in temperatures? Biologists have now shown that little auks, the most common seabirds in the Arctic, are adapting their fishing behavior to warming surface waters in the Greenland Sea. So far, their reproductive and survival rates have not been affected. However, further warming could threaten the species.

Scientists core into California's Clear Lake to explore past climate changeScienceDaily.com | 04 May 2012
One of the oldest lakes in the world, Clear Lake in northern California has deep sediments that contain a record of the climate and local plants and animals going back perhaps 500,000 years. Scientists are drilling cores from the sediments to explore 130,000 years of this history and fine-tune models for predicting the fate of today's flora and fauna in the face of global warming and pressure from a growing human population.
Ecosystem effects of biodiversity loss could rival impacts of climate change, pollutionScienceDaily.com | 03 May 2012
Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study. There has been growing concern that the very high rates of modern extinctions -- due to habitat loss, overharvesting and other human-caused environmental changes -- could reduce nature's ability to provide goods and services like food, clean water and a stable climate.
Stream temperatures don't parallel warming climate trendScienceDaily.com | 03 May 2012
A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate.
'Warming hole' delayed climate change over eastern United StatesScienceDaily.com | 27 Apr 2012
Climate scientists have discovered that particulate pollution in the late 20th century created a "warming hole" over the eastern United States -- that is, a cold patch where the effects of global warming were temporarily obscured. The findings have implications for industrial nations (like China) that have not yet tightened air quality regulations.
Study finds surprising Arctic methane emission sourceScienceDaily.com | 26 Apr 2012
The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine sediments, is vulnerable to being released into the atmosphere, where it can add to global warming. Now a multi-institutional study has uncovered a surprising and potentially important new source of Arctic methane: the ocean itself.
Geophysicists employ novel method to identify sources of global sea level riseScienceDaily.com | 26 Apr 2012
As the Earth's climate warms, a melting ice sheet produces a distinct pattern of sea level change known as its sea level fingerprint. Now, geophysicists have found a way to identify the sea level fingerprint left by a particular ice sheet, and possibly enable a more precise estimate of its impact on global sea levels.
Northern Canada feels the heat: Climate change impact on permafrost zonesScienceDaily.com | 26 Apr 2012
As climate change in the near future is likely to bring raised temperatures at northern latitudes, the characteristics of permafrost could greatly change. Changes to permafrost could have serious impact on existing and future northern infrastructures such as pipelines and could significantly affect...
Sea change in salinity heralds shift in rainfallReuters | 26 Apr 2012
SINGAPORE (Reuters) - Scientists have detected a clear change in salinity of the world's oceans and have found that the cycle that drives rainfall and evaporation has intensified more than thought because of global warming.
U.S. voters favor regulating carbon dioxide: surveyReuters | 26 Apr 2012
WASHINGTON (Reuters) - Three out of four U.S. voters favor regulating carbon dioxide as a greenhouse-gas pollutant, and a majority think global warming should be a priority for the president and Congress, a survey of American attitudes on climate and energy reported on Thursday.
