British butterfly is evolving to respond to climate change
— 2 Dec 2011 10:50 | BiologyAs global temperatures rise and climatic zones move polewards, species will need to find different environments to prevent extinction. New research, published today in the journal Molecular…
Climate sensitivity to CO2 more limited than extreme projections
— 25 Nov 2011 09:00 | EnvironmentA new study suggests that the rate of global warming from doubling of atmospheric carbon dioxide may be less than the most dire estimates of some previous studies - and, in fact, may…
Researchers pinpoint date and rate of Earth's most extreme extinction
— 18 Nov 2011 17:09 | Geology and palaeontologyIt's well known that Earth's most severe mass extinction occurred about 250 million years ago. What's not well known is the specific time when the extinctions occurred. A team of researchers…
Rare alpine insect may disappear with glaciers
— 6 Apr 2011 18:43 | EnvironmentLoss of glaciers and snowpack due to climate warming in alpine regions is putting pressure on a rare aquatic insect, the meltwater stonefly, according to a study recently released in…
Some populations of Fraser River salmon more likely to survive climate change
— 1 Apr 2011 14:42 | EnvironmentPopulations of Fraser River sockeye salmon are so fine-tuned to their environment that any further environmental changes caused by climate change could lead to the disappearance of…
Smithsonian scientists find declining rainfall is a major influence for migrating birds
— 31 Mar 2011 15:15 | BiologyInstinct and the annual increase of daylight hours have long been thought to be the triggers for birds to begin their spring migration. Scientists at the Smithsonian Conservation Biology…
Russian boreal forests undergoing vegetation change, study shows
— 29 Mar 2011 16:01 | EnvironmentRussia's boreal forest - the largest continuous expanse of forest in the world, found in the country's cold northern regions - is undergoing an accelerating large-scale shift in vegetation…
Cutting carbon dioxide helps prevent drying
— 28 Mar 2011 18:42 | EnvironmentRecent climate modelling has shown that reducing the concentration of carbon dioxide in the atmosphere would give the Earth a wetter climate in the short term. New research from Carnegie…
Uncertain future for Joshua trees projected with climate change
— 28 Mar 2011 14:27 | EnvironmentTemperature increases resulting from climate change in the Southwest will likely eliminate Joshua trees from 90 percent of their current range in 60 to 90 years, according to a new…
Think globally, but act locally when studying plants, animals, global warming
— 21 Mar 2011 16:27 | EnvironmentGlobal warming is clearly affecting plants and animals, but we should not try to tease apart the specific contribution of greenhouse gas driven climate change to extinctions or declines…
