Regional cooling does not disprove global warming. In any case, Antarctica has warmed overall over the past 50 years

Even if Antarctica was getting cooler, it would not mean the world as a whole isn't warming. Climate models do not predict an even warming of the whole planet: changes in wind patterns and ocean currents can change the way heat is distributed, leading to some parts warming much faster than average, while a few may cool, at least at first.

The overall picture is indisputable: global temperature maps show far more areas are warming than cooling. As warming continues as emissions continue to rise, eventually every part of the world will warm.

So what is happening in Antarctica? There has been uncertainty over exactly how Antarctica's climate is changing. There are few weather stations, most are on the edge rather than in the interior of the continent and records go back just a few decades.

Warming significantly
There is no doubt that the Antarctic Peninsula, which juts out from the mainland of Antarctica towards South America, has warmed significantly. A 2002 study, however, concluded that between 1966 and 2000 the continent's interior cooled.

This study was promptly seized upon as proof that the world is not warming, even though a single example of localised cooling proves no such thing, as the lead author of the 2002 study has tried to point out.

A more recent and more comprehensive study has concluded that in fact Antarctica warmed by 0.5 °C between 1957 and 2006, with especially strong warming in West Antarctica.

Blowing in circles
This does not mean the 2002 study was completely wrong. The latest study also found that for the period 1969 to 2000, there has been slight cooling over East Antarctica.

So what is going on? The cooling is due to a strengthening of the circular winds around the continent, which prevent warmer air reaching its interior. The increased wind speeds seem to be a result of cooling in the upper atmosphere, caused by the hole in the ozone layer above the pole, which is of course the result of chlorofluorocarbon (CFC) pollution.

Confusingly, it appears that one human impact on the climate - the Antarctic ozone hole - is currently compensating for another, global warming. If the ozone layer recovers over the decades as expected, the circular winds could weaken, resulting in rapid warming across the entire continent.

This raises the question of what is happening to Antarctica's ice sheets, which hold enough water to raise sea level by a catastrophic 61 metres, should it all melt. Contrary to what you might expect, the third IPPC report predicted that global warming would most likely lead to a thickening of the ice sheet over the next century, with increased snowfall compensating for any melting cause by warming.

Gravity revelations
Finding out what is actually happening to the ice is not easy. Radar measurements of the height of the ice over parts of the continent suggest that the huge East Antarctic ice sheet grew slightly between 1992 and 2003.

A more recent study based on satellite measurements of gravity over the entire continent suggests that while the ice sheets in the interior of Antarctica are growing thicker, even more ice is being lost from the peripheries. The study concluded that there was a net loss of ice between 2002 and 2005, adding 0.4 millimetres per year to sea levels (see Gravity reveals shrinking Antarctic ice). Most of the ice was lost from the smaller West Antarctic ice sheet.

Greenland, whose ice cap holds enough water to raise sea levels by 7 metres, is also losing ice overall.

The IPCC's latest prediction for sea level rise - 0.2 to 0.6 metres by 2100 - takes this ice loss into account but it is based on the assumption that the rate of ice loss will remain constant. Many researchers think this is unrealistic and that the rate of ice loss will accelerate, which means that sea level could rise much faster than predicted. But no one knows for sure what will happen and the prediction of a net gain of ice in Antarctica could yet turn out to be correct.

Climate models are unreliable.

I have decided to let global warming go, ppl will not believe until it is too late to fix it. When that happens there won't be anything we can do except to say "I TOLD YOU SO"

Hmmmm....so basically...you are saying that Global Warming equates to a belief in God.

After all...those who believe in God can't prove it...but people do anyway.

There isn't much of an argument that the Earth is warming. Even though even THAT is up for discussion since the trend in temps has been downward over the last decade or so.

The argument comes in with the thought that man can actually do anything to stop it.

The Earth has gone through heating and cooling cycles throughout it's entire existence. LONG before we showed up.

If you think we, as people, can actually stop a natural cycle...you'll be sorely disappointed when the Earth does exactly as it has done for millions upon millions of years.

I'm trying to dispel the myths, but I know how you feel!

Ever heard of Greenland? Yes... the island that is today, 90% covered by a sheet of ice. Ever wondered why the hell the vikings would name an island 90% covered by ice, Greenland? Well... Because it wasn't always covered by a sheet of ice.. Imagine that...

The little ice age.. ever heard of it? It occurred after the Medieval warming period.. WHOA... Imagine that...

I don't need computer models or Al Gore to know that the earths climate is changing. Its been changing for billions of years..

Ever heard of evolution? Wonder why species evolve? Maybe it has something to do with the changing of climates...

10 years from now people pushing this man made global warming nonsense are going to wish they were on Greenland..

Global warming doesn't refer to the weather in the sense of getting hotter.

It refers to the ocean temps that effect the world.

Show a reliable source. Your opinion is not professional.

ummmmm, actually they named the cold one Greenland and the pretty one Iceland as subterfuge to keep anyone from finding em and stealing their land

I'm not getting in the middle of the global warming thing cause I don't really know. but I couldnt help noticing that little thing

Not that I NEED to prove ANYTHING AT ALL TO YOU because you wouldn't care about the truth if it bit your a-ss.

My dad is a geologist. He told me.

Also if you watch the programs on tv about global warming they will tell you that it is the oceans warming that makes the changes they are talking about.

It really is a no brainer.

My Dad was a gynecologist and he told me storks brought kids.

Now, I don't believe everything I'm told and half of what I see.

To believe what MSM or Gov subsidized scientists reports is a real no-brainer.

I don't have to prove anything to you.

Look it up.

Global warming refers to the oceans warming not necessarily the climate.

Not really... Iceland was discovered before Greenland. Iceland was an established viking settlement and Greenland was discovered by accident. Its name came from Eric the Red so people would want to go there..

Anyway...

How dare you confuse the skeptics with facts!

LOL

Where have you been lately?

I hope you enjoyed your self, him, whatever.

LOL, him? Who is this him?

Actually just life is happening. My car died on me and stuff like the kids needing me for help.

You have been on a roll here lately...lol

I see your new project is global warming/climate change.

Good project.

Global warming/climate change education.
I thought it might actually help generate some intelligent conversation.
