The debate continues as to the cause of the more than 1,000 year-long cold interval known as the Younger Dryas. Falling on the heels of the Last Ice Age, or more correctly immediately after the two warm intervals known as the Bolling and Allerod interstadials, the Younger Dryas onset appears now to have started in as little time as one to three years. The climate shifted that suddenly from near present day warmth to near Ice Age cold. A second important feature to be noted is that apparently most of the planet was affected, and that the teleconnection between various parts of the planet was swift. This suggests strongly that the forcing mechanism resided in the atmosphere, rather than in the Ocean (where a much slower teleconnection would have been evident). The Younger Dryas however was very different from another alleged cosmic encounter, that of the great Cretaceous extinction event of approximately 65 million years ago. At this time, a huge bolide struck the Gulf of Mexico. Likely measuring as much as ten kilometres' across, the demise of the dinosaurs seems to have been assured.
Earth Changes

"Let me tell you somethin', I'm gonna make a mint outta this." Al Gore is co-founder of an investment management firm that is now the fifth-largest shareholder in the Chicago Climate Exchange.
Lost in the recent headlines was Al Gore's appearance Monday in Denver at the annual meeting of the Council of Foundations, an association of the nation's philanthropic leaders.
"Time's running out (on climate change)," Gore told them. "We have to get our act together. You have a unique role in getting our act together."
Gore was right that foundations will play a key role in keeping the climate scam alive as evidence of outright climate fraud grows, just as they were critical in the beginning when the Joyce Foundation in 2000 and 2001 provided the seed money to start the Chicago Climate Exchange. It started trading in 2003, and what it trades is, essentially, air. More specifically perhaps, hot air.
The quake hit 7 miles/11 km northeast of Napa at a depth of 3 miles (5 km). The temblor could not be felt in San Francisco, a witness said.
"It's been on the beach for a while," Howell says, flipping over the decomposing, dried-out shell.
More than 30 dead turtles have been found stranded on Galveston and the Bolivar Peninsula south of Houston this month - an unusually high number that has puzzled researchers, in part because most are so decomposed that there are few clues left about why they died.
The number of strandings on these shores is double what scientists and volunteers normally see as the turtles begin nesting in April, says Howell, who patrols the beaches as part of her job with the National Oceanic and Atmospheric Administration. Of the 35 turtles found, all but three were dead. Thirty-three were Kemp's ridleys, an endangered species researchers have spent decades trying to rehabilitate.
Rear Adm. Mary Landry told reporters late Wednesday that the increased estimate is based on analysis from the federal National Oceanic and Atmospheric Administration.
"This is not an exact science when you estimate the amount of oil," Landry said, noting there are a lot of variables in calculating the rate of the spill.
"However, NOAA is telling me now that they prefer we use the 5,000 barrels [210,000 gallons] a day as an estimate of what has actually leaked from this well and will continue to leak until BP secures the source."
Some 250,000 gallons of oily water has been collected from the scene, she said.
But when a fox raided Gianni's enclosure and killed all of the hens inside, Gianni felt it was time for a change. Within days the bird was laying eggs and trying to hatch them as he began his new life as a hen.
The sex-change chicken has baffled scientists at the UN's Farm and Agriculture Organisation, who are now planning to study Gianni's DNA to see what made him change.
An expert at the centre said: 'It may be a primitive species survival gene. With all the females gone he could only ensure the future of his line by becoming female.'
The agency warned of "dangerous winter weather conditions" for Calgary and surrounding areas, including Airdrie, Sundre, Okotoks, Olds and Strathmore. More than a dozen flights have been cancelled at the Calgary International Airport.
The RCMP said Highway 533, west of Nanton from Highway 2 to 22, is not recommended for travel because of heavy snow and poor road conditions. An intense weather system is also bringing winds gusting up to 70 km/h.
Goldberg stressed that man should separate the concept of climate change from environmental issues. He holds that climate change is natural and caused by the sun activity, but the urban heat island effect and environmental problems are mainly caused by human activities and behavior. In an exclusive interview with People's Daily Online, Goldberg explained his ideas.
History of climate on earth
"We could have an ice age any time," Dr. Goldberg says, "Over the past one million years, we have experienced eight ice ages. Eighty percent of the last million years was ice age. We are lucky to live in this short inter-glacial period."
Recently, there have been renewed efforts to pressure organic agriculture to abandon one of its foundational principles and accept genetically modified crops. While there may be nothing inherently wrong with contemplating a theoretical overlap between biotech crop genetics and organic farming systems, there's not a compelling set of reasons to do so, either.
Guido Bertolaso, the head of Italy's civil protection agency, said that while Vesuvius was more commonly considered the nation's most worrisome volcano, Ischia, which last erupted 700 years ago, was experiencing a build-up of magma.
No eruption is imminent, but "if I had to say which is the volcano with the most loaded gun barrel, I'd say it's not Vesuvius but the island of Ischia", Mr Bertolaso said in Rome.
Ischia, a short hydrofoil trip from the port of Naples and the chic vacation island of Capri, is often overrun with Italian and foreign visitors seeking to ease their aches and pains in pools filled with thermal waters pumped in from the sea.
Ischia's "magma chamber is loading up", said Mr Bertolaso, whose agency's mandate includes both disaster relief and prevention. An eruption on Ischia "could be worse than a hypothetical Vesuvius eruption", he said.











Comment: Hmm...perhaps this sheds some light on this poor rooster's plight: "Scientists are warning that manmade pollutants which have escaped into the environment mimic the female sex hormone oestrogen" from Men under threat from 'gender bending' chemicals.
