Tony Wood: Siberia is MeltingThe apocalyptic scenes in European Russia – thousands burned out of their homes, millions of hectares of crops destroyed, Moscow wreathed in smoke from smouldering peat bogs – have dominated news reports. Further east, as Tony Wood discovered, the permafrost is melting. The city of Yakutsk is in the middle of the coldest inhabited region on earth, the Sakha Republic. Temperatures of -68°C have been recorded there. The permafrost extends 250 to 350 metres below the city. Elsewhere it reaches depths of almost a mile. The effects its melting will have, both locally and globally, are potentially devastating

Climate Change Implicated in Decline of Horseshoe Crabs
ScienceDaily (Sep. 1, 2010) — A distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes.

El Niños Are Growing Stronger, NASA/NOAA Study Finds
ScienceDaily (Aug. 27, 2010) — A relatively new type of El Niño, which has its warmest waters in the central-equatorial Pacific Ocean, rather than in the eastern-equatorial Pacific, is becoming more common and progressively stronger, according to a new study by NASA and NOAA. The research may improve our understanding of the relationship between El Niños and climate change, and has potentially significant implications for long-term weather forecasting.

‘Dry Water’ Could Make a Big Splash Commercially, Help Fight Global Warming
ScienceDaily (Aug. 26, 2010) — An unusual substance known as “dry water,” which resembles powdered sugar, could provide a new way to absorb and store carbon dioxide, the major greenhouse gas that contributes to global warming

Sea Level to Rise Even With Aggressive Geo-Engineering and Greenhouse Gas Control, Study Finds
ScienceDaily (Aug. 24, 2010) — New findings by international research group of scientists from England, China and Denmark just published suggest that sea level will likely be 30-70 centimetres higher by 2100 than at the start of the century even if all but the most aggressive geo-engineering schemes are undertaken to mitigate the effects of global warming and greenhouse gas emissions are stringently controlled.

Drought Drives Decade-Long Decline in Plant Growth
ScienceDaily (Aug. 21, 2010) — Global plant productivity that once was on the rise with warming temperatures and a lengthened growing season is now on the decline because of regional drought, according to a new study of NASA satellite data.

Is the Ice in the Arctic Ocean Getting Thinner?ScienceDaily (Aug. 20, 2010) — The extent of the sea ice in the Arctic will reach its annual minimum in September. Forecasts indicate that it will not be as low as in 2007, the year of the smallest area covered by sea ice since satellites started recording such data. Nevertheless, sea ice physicists at the Alfred Wegener Institute are concerned about the long-term equilibrium in the Arctic Ocean.

Common orchid gives scientists hope in face of climate change
A study led by scientists from the Royal Botanic Gardens, Kew’s Jodrell Laboratory, which focuses on epigenetics in European common marsh orchids, has revealed that some plants may be able to adapt more quickly to environmental change than previously thought. The new study, published in Molecular Biology and Evolution, brings new hope to plant conservation.

Butterflies Shed Light on How Some Species Respond to Global Warming
ScienceDaily (Aug. 9, 2010) — With global warming and climate change making headlines nearly every day, it could be reassuring to know that some creatures might cope by gradually moving to new areas as their current ones become less hospitable. Nevertheless, natural relocation of species is not something that can be taken for granted, according to Jessica Hellmann, Associate Professor at the University of Notre Dame Department of Biological Science in Notre Dame, Ind. By studying two species of butterfly, she and her team have found evidence suggesting that a number of genetic variables affect whether and how well a species will relocate.

Our Diminished Oceans
Bill McKibben
What may turn out to be the summer’s most important news story (and just
possibly the millennium’s) didn’t make the pages of the Times. A study
in Nature last week concluded that as oceans warmed, phytoplankton—the
tiny organisms that form the crucial first level of the entire marine
food chain—were disappearing. In fact, since you need a subscription to
read the whole study, let me reprint the key portion of the abstract here:

Greenland Glacier Calves Island Four Times the Size of Manhattan
