Antarctic ice shelf set to collapse due to warming Mon Jan 19, 2009 9:14pm GMT
WILKINS ICE SHELF, Antarctica (Reuters) - A huge Antarctic ice shelf is on the brink of collapse with just a sliver of ice holding it in place, the latest victim of global warming that is altering maps of the frozen continent.
The flat-topped shelf has an area of thousands of square kilometers, jutting 20 meters (65 ft) out of the sea off the Antarctic Peninsula.
But it is held together only by an ever-thinning 40-km (25-mile) strip of ice that has eroded to an hour-glass shape just 500 meters wide at its narrowest.
just because one region has more ice doesn't mean it is warmer. as a matter of fact? warmer temps just north cause more water to be evaporated into the air so they can be deposited elsewhere...
this in turn does not mean that Antarctica is colder...
ice is formed at 32. you can in fact have ten time more ice and still be warmer than 10 below...
why don't you go bother your ex-wife or your kids that can't stand you either

Surveyed scientists agree global warming is real
Most earth scientists believe humans cause of global warming, according to survey 97 percent of climatologists canvassed believe humans play a role Petroleum geologists and meteorologists were among the biggest doubters
(CNN) -- Human-induced global warming is real, according to a recent U.S. survey based on the opinions of 3,146 scientists. However there remains divisions between climatologists and scientists from other areas of earth sciences as to the extent of human responsibility.
Against a backdrop of harsh winter weather across much of North America and Europe, the concept of rising global temperatures might seem incongruous.
However the results of the investigation conducted at the end of 2008 reveal that vast majority of the Earth scientists surveyed agree that in the past 200-plus years, mean global temperatures have been rising and that human activity is a significant contributing factor in changing mean global temperatures.
The study released today was conducted by academics from the University of Illinois, who used an online questionnaire of nine questions. The scientists approached were listed in the 2007 edition of the American Geological Institute's Directory of Geoscience Departments.
Two questions were key: Have mean global temperatures risen compared to pre-1800s levels, and has human activity been a significant factor in changing mean global temperatures?
About 90 percent of the scientists agreed with the first question and 82 percent the second.
The strongest consensus on the causes of global warming came from climatologists who are active in climate research, with 97 percent agreeing humans play a role.
Petroleum geologists and meteorologists were among the biggest doubters, with only 47 percent and 64 percent, respectively, believing in human involvement.
"The petroleum geologist response is not too surprising, but the meteorologists' is very interesting," said Peter Doran associate professor of earth and environmental sciences at the University of Illinois at Chicago, and one of the survey's authors.
"Most members of the public think meteorologists know climate, but most of them actually study very short-term phenomenon."
However, Doran was not surprised by the near-unanimous agreement by climatologists.
"They're the ones who study and publish on climate science. So I guess the take-home message is, the more you know about the field of climate science, the more you're likely to believe in global warming and humankind's contribution to it.
"The debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes," said Doran.

Well, maybe that explains where the left has gone wrong! Of course, temperatures have risen compared to the pre-1800s levels, we were in the Little Ice Age until the mid 1800s! The left apparently doesn't even understand recent history - let alone global warming!!!

The biggest problem here is that, if you believe man is to blame for global warming, how do you get it's biggest offenders (Russia, China, India) to comply with anything? China has already said it pretty much will not comply with anything because it doesn't want it's economy affected and China may very well be the biggest offender.
Let's say global warming is a hoax or is not really happening, or that it is not influenced by man. Shouldn't we still want to take care of the planet? I lived in Montana for a number of years and when I visited LA, THE AIR MADE MY EYES WATER!
I also don't understand how the "right" cannot see this as a huge money-making op. Wind energy, solar energy, clean transportation, natural gas (which burns clean and the US has hundreds of years of supply), bio fuels, etc.

YEP!
And if done now rather than waiting 'til some one else gets it going, we can be the ones selling the equipment and technology to the world, instead of buying what they sell.
It is coming. It is inevitable.

Yes, we should take care of the planet. We have done that and the air is much cleaner today than it was a few decades ago.

The right is all for making money and all for alternate energy sources, especially if it will keep hundreds of billions of our dollars each year from going to other countries for oil! However, that energy MUST be cost competitive with oil, otherwise it doesn't make sense and will hurt our country.
Obama could do a LOT to move us to natural gas in cars and trucks, but will he? The environmental wackos will scream and cry if he talks about increased drilling of natural gas! The same is true of nuclear power - the wackos are against it. Wind power - it hurts the view as Ted Kennedy is sailing his yacht! Let's get real here - the leftos will fight almost every effort to switch to alternate forms of energy! That's why they are WACKOS!

...and bdgee, you just constantly prove how irrelevant you are. You write in flowery run-on sentences trying to con people into thinking you are intellegent, when the truth is that you can't put together an intellegent thought. Maybe someday, you'll finish grade school and learn to write a coherent sentence, instead of trying to retain your title of 2nd grade bully! In the mean time, you'll just continue to be a big joke!

Well, I have to admit, PM, I haven't the talent to put together any thought so that that you might be able to understand, but as I explained to generations of poor performing college students, failure on your part to be capable of comprehending is not a failure of any sort on my part.
In that respect, I am just like everyone else here that isn't you.
