Winter Temperatures and the Arctic Oscillation

If you live nearly anywhere in North America, Europe, or Asia, it’s no news that December 2009 and early January 2010 were cold. This image illustrates how cold December was compared to the average of temperatures recorded in December between 2000 and 2008. Blue points to colder than average land surface temperatures, while red indicates warmer temperatures. Much of the Northern Hemisphere experienced cold land surface temperatures, but the Arctic was exceptionally warm. This weather pattern is a tale-tell sign of the Arctic Oscillation.
The Arctic Oscillation is a climate pattern that influences winter weather in the Northern Hemisphere. It is defined by the pressure difference between air at mid-latitudes (around 45 degrees North, about the latitude of Montreal, Canada or Bordeaux, France) and air over the Arctic. A low-pressure air mass dominates the Arctic, while high pressure systems sit over the mid-latitudes. The strength of the high- and low-pressure systems oscillates. When the systems are weaker than normal, the pressure difference between the Arctic and mid-latitudes decreases, allowing chilly Arctic air to slide south while warmer air creeps north. A weaker-than-normal Arctic Oscillation is said to be negative. When high and low pressure systems are strong, the Arctic Oscillation is positive....

Chevron In Ecuador

The Campaign for Justice in Ecuador

About This Blog
For over three decades, Chevron chose profit over people in the Ecuadorian Amazon. The cold and calculated decision to save $3 per barrel and yet poison entire communities is compounded daily as Chevron continues its PR campaign to suppress the truth and barrage the media with lies about its actions and responsibility. This blog is part of an ever-growing campaign to counter Chevron's misinformation tactics and speak frankly about their attempts to hide their role in the world's worst oil-related disaster.

Video-Message from Ecuador to New Chevron CEO




This is the message that Emergildo Criollo, leader of the indigenous Cofan tribe in Ecuador's Amazon region, is sending to John Watson, the new CEO of Chevron, in a new video.

Just days into Mr. Watson's tenure as Chairman and CEO of California-based Chevron Corporation, the affected communities in the Ecuadorian Amazon have recorded a heartfelt video message, in which they appeal directly to Watson to visit Ecuador, and address the oil company's toxic legacy.

Climate change emails between scientists reveal flaws in peer review

The research director at the centre of a row over climate change data said he would stand down from the post while there is an independent review.
Professor Phil Jones, director of the Norwich-based University of East Anglia's (UEA) Climatic Research Unit (CRU), has said he stands by his data.
Sceptics claim the e-mails, leaked after a UEA server was hacked into, showed data was being manipulated.
The hacking of the computer is being investigated by Norfolk Police.
The files stolen from the computer include documents, detailed data and private e-mails exchanged between leading climate boffin's
