Debrox Nothing Coming Out

record low of Arctic ice coverage has always




While most of the world continues to ignore climate change, they are relentlessly. The center of the polar sea ice measurements of NASA's laconically announced on February 2 that the extension del ghiaccio marino artico nel gennaio 2011 è stata la più bassa da quando esistono misurazioni satellitari di questo genere, ossia dal 1979. L’oscillazione dell’estensione del ghiaccio artico ha persistito nella sua fase di forte diminuzione per la maggior parte del mese, mantenendo bassa l’estensione del ghiaccio. Questo dato dimostra anche che l’ondata di freddo polare che ha investito il Nord America quest’anno non ha di certo un’influenza positiva sulla crescita dei ghiacci artici, mentre il contrario è probabile.

Panoramica delle condizioni

L’estensione media del ghiaccio marino artico a gennaio 2011 è stata 13,55 milioni km quadrati. Questa è stata la più low ice extent recorded in the month of January since records satellite in 1979. It is 50 thousand square kilometers below the record low of 13,60 million square kilometers, registered in 2006 and 1.27 million square kilometers below the average between 1979 to 2000.

The ice extent in January 2011 has been unusually low in Hudson Bay, Hudson Strait (between the south of Baffin Island and Labrador), and Davis Strait (between Baffin Island and Greenland). Normally, these areas are frozen by the end of November, but this year the Hudson Bay did not completely freeze until mid-January. The Labrador Sea remained largely ice-free.

January 2011 than in previous years

January 2011 had the lowest ice extent since satellite record. The linear rate of decline for the month was -3.3% per decade.

The extension of ice in the Arctic has increased by an average of 42.8 thousand square kilometers per day during the month of January, a figure in the media.

air temperatures over most of the Arctic were 2 to 6 degrees Celsius above normal for the month of January. Over the Canadian Arctic Archipelago, Baffin Bay and the Straits of Labrador, temperatures are were at least 6 degrees Celsius above the average for the period. Temperatures were above average in the western Canadian Archipelago and over Scandinavia. How

last December 2010, the warm temperatures in January have two reasons: ocean areas not covered by ice that release heat into the atmosphere, and winds that continue to send warm air to the north.
