Dating an ancient episode of severe global warming
ScienceDaily (June 16, 2011) — Using sophisticated methods of dating rocks, a team including University of Southampton researchers based at the National Oceanography Centre, Southampton, have pinned down the timing of the start of an episode of an ancient global warming known as the Paleocene-Eocene thermal maximum (PETM), with implications for the triggering mechanism.The early … Continue reading
Global warming may increase the capacity of trees to store carbon
ScienceDaily (May 31, 2011) — One helpful action anyone can take in response to global warming is to plant trees and preserve forests. Trees and plants capture carbon dioxide during photosynthesis, thereby removing the most abundant greenhouse gas from the atmosphere and storing some of it in their woody tissue.Yet global warming may affect the … Continue reading
Ocean warming detrimental to inshore fish species, Australian scientists report
ScienceDaily (May 20, 2011) — Australian scientists have reported the first known detrimental impact of southern hemisphere ocean warming on a fish species.The findings of a study published in Nature Climate Change indicate negative effects on the growth of a long-lived south-east Australian and New Zealand inshore species — the banded morwong.Scientific monitoring since 1944 … Continue reading
Shootingstars provide clues to likely response of plants to global warming
ScienceDaily (May 3, 2011) — Both migration and evolution played a role in the adaptation of shootingstars to warmer temperatures after the last ice age. Many scientists are concerned that plant and animal species may face extinction due to global warming, but biologists at Washington University in St. Louis are trying to predict exactly what … Continue reading
US farmers dodge the impacts of global warming — at least for now
ScienceDaily (May 8, 2011) — Global warming is likely already taking a toll on world wheat and corn production, according to a new study led by Stanford University researchers. But the United States, Canada and northern Mexico have largely escaped the trend.“It appears as if farmers in North America got a pass on the first … Continue reading
Earth recovered from prehistoric global warming faster than previously thought
ScienceDaily (Apr. 21, 2011) — Earth may be able to recover from rising carbon dioxide emissions faster than previously thought, according to evidence from a prehistoric event analyzed by a Purdue University-led team.When faced with high levels of atmospheric carbon dioxide and rising temperatures 56 million years ago, Earth increased its ability to pull carbon … Continue reading
Agulhas ocean current ‘leakage’, fueled by global warming, could stabilize Atlantic overturning circulation
ScienceDaily (Apr. 27, 2011) — The Agulhas Current which runs along the east coast of Africa may not be as well known as its counterpart in the Atlantic, the Gulf Stream, but researchers are now taking a much closer look at this current and its “leakage” from the Indian Ocean into the Atlantic Ocean. In … Continue reading
Democrats and Republicans increasingly divided over global warming, study finds
ScienceDaily (Apr. 23, 2011) — Despite the growing scientific consensus that global warming is real, Americans have become increasingly polarized on the environmental issue, according to a first-of-its-kind study led by a Michigan State University researcher.The gap between Democrats and Republicans who believe global warming is happening increased 30 percent between 2001 and 2010 — … Continue reading
Global warming won’t harm wind energy production, climate models predict
ScienceDaily (May 2, 2011) — The production of wind energy in the U.S. over the next 30-50 years will be largely unaffected by upward changes in global temperature, say a pair of Indiana University Bloomington scientists who analyzed output from several regional climate models to assess future wind patterns in America’s lower 48 states.Their report … Continue reading
Penguins that shun ice still lose big from a warming climate
ScienceDaily (Apr. 11, 2011) — Fluctuations in penguin populations in the Antarctic are linked more strongly to the availability of their primary food source than to changes in their habitats, according to a new study published online on April 11 in the Proceedings of the National Academy of Sciences. Funded in part by the Lenfest … Continue reading
