'The Earth todays stands in imminent peril'



Terrifying article. Is anyone in power listening?

The Independent (uk): The Earth today stands in imminent peril
and nothing short of a planetary rescue will save it from the environmental cataclysm of dangerous climate change. Those are not the words of eco-warriors but the considered opinion of a group of eminent scientists writing in a peer-reviewed scientific journal.


The unnatural "forcing" of the climate as a result of man-made emissions of carbon dioxide and other greenhouse gases threatens to generate a "flip" in the climate that could "spark a cataclysm" in the massive ice sheets of Antarctica and Greenland, the scientists write.

Dramatic flips in the climate have occurred in the past but none has happened since the development of complex human societies and civilisation, which are unlikely to survive the same sort of environmental changes if they occurred now.

"Civilisation developed, and constructed extensive infrastructure, during a period of unusual climate stability, the Holocene, now almost 12,000 years in duration. That period is about to end,"
the scientists warn. Humanity cannot afford to burn the Earth's remaining underground reserves of fossil fuel. "To do so would guarantee dramatic climate change, yielding a different planet from the one on which civilisation developed and for which extensive physical infrastructure has been built," they say.

Dr Hansen said we have about 10 years to put into effect the draconian measures needed to curb CO2 emissions quickly enough to avert a dangerous rise in global temperature. Otherwise, the extra heat could trigger the rapid melting of polar ice sheets, made far worse by the "albedo flip" - when the sunlight reflected by white ice is suddenly absorbed as ice melts to become the dark surface of open water.


The glaciers and ice sheets of Greenland in the northern hemisphere, and the western Antarctic ice sheet in the south, both show signs of the rapid changes predicted with rising temperatures."


Independent (uk): Climate change brings early spring in the Arctic


The Arctic spring is coming two weeks ahead of time compared to a decade ago, with birds, butterflies, flowers and small animals all appearing earlier in the year as a result of climate change.

A study of a range of animals and plants living in the high Arctic has revealed that many of them are responding to the earlier spring by flowering or laying their eggs significantly ahead of their normal times of the year.

On average, the breeding and flowering seasons in the Arctic have shifted by 14.5 days but some species of mosquitoes have begun laying their eggs 30 days earlier than in the mid 1990s
, Toke Hoye, of the University of Copenhagen in Denmark, said.

"Our study confirms what many people already think, that the seasons are changing and it is not just one or two warm years but a trend seen over a decade," Dr Hoye said. "This is the most extensive study of its kind in the Arctic in terms of the number and variety of species and the replication of the observations."

Bee Colony Collapse

wikipedia: bees

What's causing the collapse of the honeybee colonies? The theories include genetically-engineered corn, predators, cellphones, and the stress of being corporately farmed. When I read that genetically-modified corn contains a neurotoxin (brain cell killer) that kills honeybees, I thought 'bingo'. Monsanto has killed the honeybees. It all makes sense now. They'll probably manufacture some new chemical to sell us to replace the honeybees.

The disappearance of the bees hits New Jersey


Quotes from a Newark Star-Ledger article:

[Beekeeper] Tassot and his wife believe they know why their bees have disappeared.

“We have suspicions about pesticides,” he said. “We noticed most of the dead hives are close to cornfields. … And when we asked other beekeepers what was the principle crop near their hives, they said corn, corn, corn.”

Simone, of Morris Township, agrees. “When I spoke with other beekeepers they say all their hives with heavy losses are near cornfields.”

Many farmers in the United States and around the world rely on genetically engineered corn to survive the assault of crop-killing insects. The seeds are coated with a systemic pesticide that is essentially built into the corn as it grows.

One of the chief chemicals used is a neurotoxin called imidacloprid, which is manufactured by the German company Bayer CropScience. Imidacloprid works by blocking a pathway in insect brains that results in an accumulation of a neurotransmitter which, in insects, leads to paralysis and death.

At sublethal doses, however, imidacloprid is toxic to honeybees.
In a 2001 article in the Journal of Pesticide Reform, German scientist Eric Zeisstoff wrote that his research “indicated that bees affected by imidacloprid suffer problems with orientation. Bees with a particular level of imidacloprid contamination at 500 meters from the colony did not return to the hive at all.”

Frogs and Bees are the Canaries in our Coal Mine

Endangered

They're dying, and no one knows why. Global warming? Pollution? The cumulative effects of the 500 new chemicals which are introduced into our environment every year? Whatever the answer, it's bad news for the planet.

Marin County Coastal Post Online: The Frogs Are Dying

ATLANTA - Ponds and swamps are becoming eerily silent. The familiar melody of ribbits, croaks and chirps is disappearing as a mysterious killer fungus wipes out frog populations around the globe, a phenomenon likened to the extinction of dinosaurs.

Scientists from around the world are meeting Thursday and Friday in Atlanta to organize a worldwide effort to stem the deaths by asking zoos, aquariums and botanical gardens to take in threatened frogs until the fungus can be stopped.

The aim of the group called Amphibian Ark is to prevent the world's more than 6,000 species of frogs, salamanders and wormlike Sicilians from disappearing. Scientists estimate up to 170 species of frogs have become extinct in the past decade from the fungus and other causes, and an additional 1,900 species are threatened.


NYTimes (Feb. 27): Honeybees Vanish, Leaving Keepers in Peril


[B]ee losses are ranging from 30 to 60 percent on the West Coast, with some beekeepers on the East Coast and in Texas reporting losses of more than 70 percent; beekeepers consider a loss of up to 20 percent in the offseason to be normal.
NYTimes (Feb. 12): Mystery Disease Is Threat to Bee Colonies

A mysterious illness is killing tens of thousands of honeybee colonies across the country, threatening honey production, the livelihood of beekeepers and possibly crops that need bees for pollination.

Researchers are scrambling to find the cause of the ailment, called colony collapse disorder.

Reports of unusual colony deaths have come from at least 22 states. Some commercial beekeepers have reported losing more than 50 percent of their bees.
