Antarctica nu pricepe ca trebuie sa respecte deciziile UE si SUA

Antarctica nu vrea sa priceapa: este moda incalzirii globale, deci jos gheata. 

Gheata Antarcticii creste, nu scade 

ICE is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap.

The results of ice-core drilling and sea ice monitoring indicate there is no large-scale melting of ice over most of Antarctica, although experts are concerned at ice losses on the continent’s western coast.

Antarctica has 90 per cent of the Earth’s ice and 80 per cent of its fresh water. Extensive melting of Antarctic ice sheets would be required to raise sea levels substantially, and ice is melting in parts of west Antarctica. The destabilisation of the Wilkins ice shelf generated international headlines this month.

However, the picture is very different in east Antarctica, which includes the territory claimed by Australia.

East Antarctica is four times the size of west Antarctica and parts of it are cooling. The Scientific Committee on Antarctic Research report prepared for last week’s meeting of Antarctic Treaty nations in Washington noted the South Pole had shown „significant cooling in recent decades”.

Australian Antarctic Division glaciology program head Ian Allison said sea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east Antarctica.

„Sea ice conditions have remained stable in Antarctica generally,” Dr Allison said.

The melting of sea ice – fast ice and pack ice – does not cause sea levels to rise because the ice is in the water. Sea levels may rise with losses from freshwater ice sheets on the polar caps. In Antarctica, these losses are in the form of icebergs calved from ice shelves formed by glacial movements on the mainland.

Last week, federal Environment Minister Peter Garrett said experts predicted sea level rises of up to 6m from Antarctic melting by 2100, but the worst case scenario foreshadowed by the SCAR report was a 1.25m rise.

Mr Garrett insisted global warming was causing ice losses throughout Antarctica. „I don’t think there’s any doubt it is contributing to what we’ve seen both on the Wilkins shelf and more generally in Antarctica,” he said.

Cine amendeaza Antarctica pentru ca nu se supune „teoriilor demonstrate” de oamenii de stiinta de la ONU?

  2. Vad ca se promoveaza ideea ca incalzirea globala ar fi o facatura sau ceva de genul asta. Nu pot sa stiu cum e in Burundi. Dar e cert ca in Campia Romana sau cel putin in Baragan clima s-a schimbat in ultima decada si lucrul asta il poate spune oricine lucreaza efectiv in agricultura. Cantitatea de precipitatii sub forma de zapada a scazut. Ploua mult mai rar. Solul e mai uscat.

    • Au fost ani mai lipsiti de precipitatii, stai linistit. Nimeni nu zice ca nu e o incalzire usoara, dar e ciclica si s-a mai intamplat.

      Daca ar fi sa citesti raportul de aici

      si sa vezi link-urile catre lucrarile oamenilor de stiinta, ideea de „facatura” devine destul de pregnanta. Si nu sunt 2-3 care spun ca teoria nu-i corecta.

      In addition, the following developments further secured 2008 and 2009 as the year the “consensus” collapsed. Russian scientists “rejected the very idea that carbon dioxide may be responsible for global warming”. An American Physical Society editor conceded that a “considerable presence” of scientific skeptics exists. An International team of scientists countered the UN IPCC, declaring: “Nature, Not Human Activity, Rules the Climate”.
      India Issued a report challenging global warming fears. International Scientists demanded the UN IPCC “be called to account and cease its deceptive practices,” and a canvass of more than 51,000 Canadian scientists revealed 68% disagree that global warming science is “settled.” A Japan Geoscience Union symposium survey in 2008 “showed 90 per cent of
      the participants do not believe the IPCC report.”
