Lubang di Lapisan Ozon Menghentikan Es Mencair di Antartika
(Hole in ozone layer stopping Antarctica from melting)
 |
It may be giving us skin cancer, but scientists are now singing its praises for a redeeming quality - it's stopping Antarctica from melting.
Fresh research from Britain shows Antarctica is getting bigger as the ice around it increases.

Antarctica's icy resilience has provided a quirky front in the war of words over climate change.

Antarctica's icy resilience has provided a quirky front in the war of words over climate change.
The boffins at the British Antarctic Survey say Antarctica's increasing ice girth is not inconsistent with global warming - it's the ozone hole that is responsible.
The hole is causing more storms and more fierce winds around the South Pole, and that's cooling down much of Antarctica.
``In the Antarctic human influence through the ozone hole has ... resulted in more ice,'' said John Turner, the lead author of the British research.
``The ozone hole is in many ways holding back the effects of greenhouse gas increases in the Antarctic.''
Humans now face a dilemma - to repair the ozone hole or leave it be.
The ozone hole was caused by chlorofluorocarbons (CFCs), which have a long life in the atmosphere.
World leaders agreed to ban CFCs back in 1987. Scientists say the hole will close over the next 50 years.
Prof Turner said Antarctic sea ice would be reduced by about one-third when that happened.
Australian Climate Change Minister Penny Wong said the research was not proof that global warming was a myth.
``It is clear from the consensus science ... that climate change is happening and that human activity is contributing to it,'' Senator Wong told reporters in Adelaide.
Senator Wong said there had been plenty of debate around the science and it was time for action.
More research was needed into the Antarctic ice question, she said.

The British research was published in the journal Geophysical Research Letters.

First we had global warming now we have climate change. We were informed that the polar ice caps were melting and now they are not hmmmm. The truth ladies and gentlemen is that we have nearly reached the cycle of 13 batkuns or 22000 years which last time causes an ice age yes an ice age. If you have read about the mayan people and there calendar this is supposed to occour in the northern hemisphere winter solisite on the 24 deceber 2012 Hmmm better go out now and get some thermals might be getting a wee bit chilly soon

Maybe Krudd could solve the economic recession if all the scientists on government research grants into the potential effects of CO2 on our weather were sacked. It would appear from comments by online readers over the past twelve months that only the above plus Penny Wong, Ross Garnaut and Peter Garrett believe that Global Warming is real. Most folk not directly receiving financial benefit from the Government believe that the Global Warming scare is the greatest scam since human interference was alleged to be responsible for the hole in the ozone layer.

The experts tell us the world has been in existance for 4,500 million years. If you can not beleive that our current set of circumstances has not happened 100s of times before, go find yourself another SHRINK. Sit back, relax and enjoy the show.
