Global Warming: Arctic map "will have to be redrawn"

"Scientists in the Arctic have just carried out the first research on a huge iceberg the size of Manhattan."

"For 3,000 years, this colossal block of ice was securely fixed to the coast as part of the Ayles Ice Shelf - but now it is drifting free."

"Climate scientists predict that the Arctic will continue to warm - so the expectation is that the five remaining ice shelves here could also break away. The effect already is that the map of the Arctic will have to be redrawn."

"with the current rate of warming, those ice shelves are likely never to be reconstituted."

"according to Dr Copland, the fact that such thick ice could split apart in less than an hour - as it did back in August 2005 - illustrates a more alarming point.

"This shows how climate change can trigger very sudden changes even on a massive scale - when the ice shelf broke away, the rupture registered with the force of a small earthquake," he said."

They are like schoolyard bullies and it's about time we stood up and went toe-to-toe. I'd really like to see a well stated, coherent philosophical rebuttal of the last 40 years of relentless advancement of the right - and I'd like to see that rebuttal unapologetically pushed, and see our agenda of people before profit placed front and centre.

The Nyon Conference was a diplomatic conference held in Nyon, Switzerland, in September 1937 to address attacks on international shipping in the Mediterranean Sea during the Spanish Civil War. The conference was convened in part because Italy had been carrying out unrestricted submarine warfare, although the final conference agreement did not accuse Italy directly; instead, the attacks were referred to as "piracy" by an unidentified body. Italy was not officially at war, nor did any submarine identify itself. The conference was designed to strengthen non-intervention in the Spanish Civil War.best olive oileames office chair

Over the next year, the Rippon was engaged in a blockade of the French coast. After the Napoleonic wars ended in 1814, the Rippon returned to England, and Roe was appointed as a midshipman to HMS Horatio under Captain Dillon on 17 August.

Attempting to know when the raids will come is futile. The only answer is to always be in a position to take advantage of them rather than be crushed by them. Their objective is to drain your funds so don't let it happen. Dont over commit. Have funds earmarked for raid opportunities. In the meantime trade as though there is no EE raid coming. They win when they have us always concerned about the possibility.

Frank Black and the Catholics. He reformed the Pixies in 2004 and continues to release solo records and tour as a solo artist. His vocal style has varied from a screaming, yowling delivery as lead vocalist of the Pixies to a more measured and melodical style in his solo career. His cryptic lyrics mostly explore unconventional subjects, such as surrealism, incest and biblical violence

The start of cultural-linguistic activities by Slovene intellectuals of the time brought about a national revival and the birth of the Slovene nation in the modern sense of the word. Before the Napoleonic Wars, some secular literature in Slovene emerged.

I can say your painting is far from crap if these are the results you produce! I'd be more than happy with that standard of painting. Thanks also for the tip of using a dark green-gray as a highlight for black. I will try it. I find a sand/buff color useful for red highlights.

This army, which was sent on repeated expeditions into neighboring provinces, exacted harsh penalties against communities resistant to Merina domination; mass executions were common, and those who were spared their lives were commonly brought back to Imerina as slaves (andevo) and their valuables seized as booty to increase the wealth of the Crown.
