Natural gas from shale contributes to global warming, researchers find
ScienceDaily (Apr. 12, 2011) — Natural gas extracted from shale formations has a greater greenhouse gas footprint — in the form of methane emissions — than conventional gas, oil and coal over a 20 year period. This calls into question the logic of its use as a climate-friendly alternative to fossil fuels, according to Robert … Continue reading
West Antarctic warming triggered by warmer sea surface in tropical Pacific
ScienceDaily (Apr. 11, 2011) — The Antarctic Peninsula has warmed rapidly for the last half-century or more, and recent studies have shown that an adjacent area, continental West Antarctica, has steadily warmed for at least 30 years, but scientists haven’t been sure why.New University of Washington research shows that rising sea surface temperatures in the … Continue reading
It’s all in a name: ‘Global warming’ vs. ‘climate change’
ScienceDaily (Mar. 9, 2011) — Many Americans are skeptical about whether the world’s weather is changing, but apparently the degree of skepticism varies systematically depending on what that change is called.According to a University of Michigan study published in the forthcoming issue of Public Opinion Quarterly, more people believe in “climate change” than in “global … Continue reading
Ancient ‘hyperthermals’ serve as guide to anticipated climate changes; Sudden global warming events more frequent?
ScienceDaily (Mar. 16, 2011) — Bursts of intense global warming that have lasted tens of thousands of years have taken place more frequently throughout Earth’s history than previously believe, according to evidence gathered by a team led by Scripps Institution of Oceanography, UC San Diego researchers.Richard Norris, a professor of geology at Scripps who co-authored … Continue reading
Kudzu vines spreading north from US Southeast with warming climate
ScienceDaily (Mar. 25, 2011) — Kudzu, the plant scourge of the U.S. Southeast. The long tendrils of this woody vine, or liana, are on the move north with a warming climate.But kudzu may be no match for the lianas of the tropics, scientists have found. Data from sites in eight studies show that lianas are … Continue reading
‘Climategate’ undermined belief in global warming among many TV meteorologists, study shows
ScienceDaily (Feb. 23, 2011) — A new paper by George Mason University researchers shows that ‘Climategate’ — the unauthorized release in late 2009 of stolen e-mails between climate scientists in the U.S. and United Kingdom — undermined belief in global warming and possibly also trust in climate scientists among TV meteorologists in the United States, … Continue reading
Arctic environment during an ancient bout of natural global warming
ScienceDaily (Feb. 27, 2011) — Scientists are unravelling the environmental changes that took place around the Arctic during an exceptional episode of ancient global warming. Newly published results from a high-resolution study of sediments collected on Spitsbergen represent a significant contribution to this endeavour.The study was led by Dr Ian Harding and Prof John Marshall … Continue reading
Global warming may reroute evolution
ScienceDaily (Feb. 16, 2011) — Rising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the University of Michigan suggests.The research focused on the effects of elevated carbon dioxide on common milkweed, Asclepias syriaca. Milkweed is one of … Continue reading
Earth warming unevenly: Tropical Atlantic sees weaker trade winds and more rainfall
ScienceDaily (Feb. 9, 2011) — Earth’s global temperature has been rising gradually over the last decades, but the warming has not been the same everywhere. Scientists are therefore trying to pin down how the warming has affected regional climates because that is what really matters to people, and to adaptation and mitigation strategies. Their efforts, … Continue reading
