Scientists investigate Ecuador's receding glaciers
...A study to be published this year by Ecuadorean glaciologist Bolivar Caceres suggests that the country's glaciers lost more than 40 percent of their surface area between 1956 and 2006.
For example, the Cotopaxi mountain with its famous volcanic cone has lost 40 percent of its glacial cap since 1976.... The gradual disappearance of the glaciers is not just a matter of aesthetic regret. Several Andean cities are thought to be dependent on the melting glaciers for part of their drinking supply, particularly in the dry season. ...

from Science News:
Rural ozone can be fed by feed (as in silage)
Livestock operations take a lot of flak for polluting. Manure lagoons not only irritate neighbors' noses but also leak nitrogen -- sometimes fostering dead zones up to 1,000 miles downstream. And ruminants can release copious amounts of methane, a greenhouse gas. Researchers are now linking ozone to livestock as well. But this time the pollution source is not what comes out the back end of an animal but what's destined to go in the front... o they began investigating animal feed, Howard says -- especially silage, grain "which has been [deliberately] fermented" and as such comes laced with a lot of alcohol... "Ethanol and especially larger alcohol species account for more than 50 percent of the ozone formation for most types of feed," Howard and his colleagues now report online, ahead of print, in Environmental Science & Technology. ...

'Paltry' Copenhagen carbon pledges point to 3 degree C rise
Pledges made at December's UN summit in Copenhagen are unlikely to keep global warming below 2C, a study concludes.
Writing in the journal Nature, analysts at the Potsdam Institute for Climate Impacts Research in Germany say a rise of at least 3C by 2100 is likely.... "There's a big mismatch between the ambitious goal, which is 2C... and the emissions reductions," said Potsdam's Malte Meinshausen. "The pledged emissions reductions are in most cases very unambitious," he told BBC News.
In their Nature article, the team uses stronger language, describing the pledges as "paltry".... "In an ideal world, if you pull off every possible emission reduction from the year 2021 onwards, you can still get to get to 2C if you're lucky," said Dr Meinshausen.
"But it is like racing towards the cliff and hoping you stop just before it."
They argue that positive analyses may "lull decision-makers into a false sense of security". ...

$44M in crops threatened by high honeybee deaths through winter
Think the 2009-10 winter was tough on you? Consider the state's honeybees.
An estimated 50 to 70 percent of hives kept by beekeepers died, said Cindy Kalis, spokeswoman for the Ohio Department of Agriculture.
The losses are in keeping with heavy fatality rates experienced since 2006 -- a year when 600,000 bee colonies in the U.S. mysteriously fled their homes and disappeared, said James Tew, Ohio State University's state honeybee specialist.
"The average person should care," he said. "Bees of all species are fundamental to the operation of our ecosystem." ...

Climate Damage Confirmed To Be Serious, Extensive
Internationally respected Mbari ocean chemist Peter Brewer says 85 percent of greenhouse gas emissions come from automobiles and fossil fuel power plants, their output equaling a million tons of carbon dioxide every hour dissolving into the ocean.
"In the long term future, where there'll be a huge swath of ocean, that will be inhospitable to marine life," said Brewer.
Research published Friday suggested that deep oceans are hiding heat that will likely accelerate global warming, spawn repeated El Nino's and quicken ocean catastrophes.... The net effect experts say, is greenhouse gas levels are greater now and rising faster than at any time humans have been on earth
"We're putting so much carbon dioxide into the atmosphere that the biosphere just can't catch up," said Baldocchi.... But scientists like Brewer and Baldocchi are pessimistic, saying climate change is happening too fast.
"I think we're going to have these changes, I wish we didn't, we better work hard to try and undo them, but right now there's not a good path for doing that," said Brewer.
"Sure we'll live, we'll survive, it just might not be a very nice world.," said Baldocchi. ...

from Telegraph.co.uk:
Frogs threatened by climate change
Scientists looked at records of frogspawn over the last decade recorded by thousands of people in Britain, including viewers of BBC's Springwatch.
The record of 50,000 sightings of frogspawn showed that the amphibians lay their eggs earlier as the temperature warms. Frogs in the south often spawn more than a week earlier to make sure their young have the best chance. But this sensitivity to the local environment makes frogs particularly vulnerable to climate change. Even modest predictions for Britain, that will see temperatures rise by around 2C (3.6F) over the next 50 years, will be too much for the frogs to cope with. "For frog populations to keep in step with medial projections of climate change for 2050-2070, they may need to spawn about 30 days earlier. Their current flexibility, however, may only enable them to spawn seven days earlier," he said. "It's unlikely that frogs will be able to evolve sufficiently rapidly." ...

Bill McKibben's must-read "Eaarth"
Bill McKibben, the writer who first brought the reality of global warming to the mainstream reader 20 years ago with The End of Nature, is understandably feeling a little dark. Well, not a little dark, a lot dark. And who can blame him. The past twenty years have created more carbons, more methane, and more pain. Progress is hard to find; hope even harder.
And so he intentionally misspells our planet's name to make a point: that we no longer live on the same planet. McKibben describes this old planet in this way. "For the ten thousand years that constitute human civilization, we've existed in the sweetest of sweet spots."
This "sweet spot" has turned sour, and the first half of Eaarth is a relentless, panoramic accounting of just how bad it's gotten, worldwide, from artic melt to extreme weather to the growth of dengue fever. This litany of global woe, he says, "Should come as body blows, as mortar barrages, as sickening thuds... Name a major feature of the earth's surface and you'll find massive change." ...

Bolivian villagers want compensation as glaciers melt
An idea has taken root there - that those who have caused the snow to retreat and the waters to slow should be brought before an international court.... What they want is an international court of environmental justice, an idea that is being pushed by Evo Morales, Bolivia's president.
"We are very worried because we have no water. Half the people of this community have already left. Those who remain are struggling with the lack of water," says Max, an elderly Aymara Indian who chews coca leaves as he speaks in heavily-accented Spanish.... "The weather has drastically changed and it is now two or three times hotter than it was. We cannot water our crops and the sun and the heat are very strong. Our crops are dry now, our animals are dying; we want to cry," Max says, before asking their Andean goddess, Pachamama or Mother Earth, for help. ...
