Because you are like fs is about alternative energy. He wouldn't believe it was viable if he was revived with a solar powered cardio crash cart.

There are articles and space pictures and scientists who say we are in a climate change. But you and fs in all y'all's wisdom know better.

I myself take it with a grain of salt but don't poo-poo it just because it doesn't fit some preconceived notion.

The planet has had many warming and cooling periods in its life, but for some reason this time man is the cause. What was the cause of the last ice age? IT seems to me that the scientists would be looking for causes to explain what happened more than 10,000 years ago to try and figure out what is the cause of the last climate change.

Thank you Dr Liberty for your insight. "I think we are seeing changes happening at an accelerated pace". Said Dr. Mikeyy

Did I say man was the cause? If you will look at the words you quoted me as saying you will see I take it with a grain of salt. But climate is changing. Maybe some would like to have that information not passed through a political sieve for once.

Of course it is. The larger part of Antarctica, for instance has been cooling for some time.

How that creates an overwhelming melt causing "dense water", is something I'd like explained.

I don't understand how people claiming to be all about "the science" aren't a little curious about that one.

I did post a link earlier showing you the rising ice, but if you don't believe that one, here's one from NSIDC

http://nsidc.org/data/seaice_index/i...plot_hires.png

Here's an old one from NASA in 2004 before the data manipulators could get at it. I imagine they've turned it from blue to red by now, because that's the sort of thing Hansen and the boys have been doing.



What's interesting though is notice how the red is down the North and West coast, and the blue is in the interior. That's what I was talking about.

This one's from a skeptic but if you click the links you'll see they come from reputable sources.

Here's the 2009 one you'll be looking for though. This is the one on Steig, the guy who smears temperatures from the peninsula all over the continent, and calls it warming.

Here's a more science-y argument against it.

This one is interesting though.

BBC News - Warm ocean driving Antarctic ice loss

A recent study thinks ocean currents are more likely to be the cause of the warming that has been happening in some parts along the North and West coast of Antarctica.

You're really going to have to twist and turn in your reasoning to blame CO2, or man for that. Never stopped em before though.

NASA
Quote:
From 2003 to 2010, NASA satellites systematically measured all of Earth's melting glacial ice--the results added up to 4.3 trillion tons of water and a global sea level rise of half an inch.

Put in perspective, that's enough ice to bury the entire U.S. 1.5-feet deep.

These calculations are detailed in a new study released today by a team of scientists at the University of Colorado. The scientists used satellite measurements from the NASA Gravity Recovery and Climate Experiment (GRACE), which launched in 2002 and focused on how melting ice from glaciers and ice caps is adding to global sea level rise.
Greenland
Quote:
WASHINGTON | Thu May 3, 2012 2:42pm EDT
(Reuters) - Some of Greenland's glaciers are moving about 30 percent faster than they did 10 years ago, contributing to rising global sea levels, but that still may not be enough to reach the most extremeResearchers have been monitoring the big ice sheets of Greenland and Antarctica for decades as one indication of the impact of human-spurred climate change.
Greenland glaciers speed up, swelling rising seas: reports | Reuters
Made of compacted snow, these glaciers can move toward the sea, and when they get there, they dump water into the oceans around them. The faster they move, the more water they add, and the higher the oceans get projections for 2100, scientists reported on Thursday.
Quote:
You may have heard about global warming. It seems that in the last 100 years the earth's temperature has increased about half a degree Celsius. This may not sound like much, but even half a degree can have an effect on our planet. According to the U.S. Environmental Protection Agency (EPA) the sea level has risen 6 to 8 inches (15 to 20 cm) in the last 100 years (see How do they measure sea level?).
This higher temperature may be causing some floating icebergs to melt, but this will not make the oceans rise. Icebergs are large floating chunks of ice. In order to float, the iceberg displaces a volume of water that has a weight equal to that of the iceberg. Submarines use this principle to rise and sink in the water by changing their weight.
But the rising temperature and icebergs could play a small role in the rising ocean level. Icebergs are chunks of frozen glaciers that break off from landmasses and fall into the ocean. The rising temperature may be causing more icebergs to form by weakening the glaciers, causing more cracks and making ice mo*re likely to break off. As soon as the ice falls into the ocean, the ocean rises a little.
If the polar ice caps melted, how much would the oceans rise?

HowStuffWorks "If the polar ice caps melted, how much would the oceans rise?"
Quote:
If the rising temperature affects glaciers and icebergs, could the polar ice caps be in danger of melting and causing the oceans to rise? This could happen, but no one knows when it might happen.
The main ice covered landmass is Antarctica at the South Pole, with about 90 percent of the world's ice (and 70 percent of its fresh water). Antarctica is covered with ice an average of 2,133 meters (7,000 feet) thick. If all of the Antarctic ice melted, sea levels around the world would rise about 61 meters (200 feet). But the average temperature in Antarctica is -37°C, so the ice there is in no danger of melting. In fact in most parts of the continent it never gets above freezing.
At the other end of the world, the North Pole, the ice is not nearly as thick as at the South Pole. The ice floats on the Arctic Ocean. If it melted sea levels would not be affecte*d.
There is a significant amount of ice covering Greenland, which would add another 7 meters (20 feet) to the oceans if it melted. Because Greenland is closer to the equator than Antarctica, the temperatures there are higher, so the ice is more likely to melt.
But there might be a less dramatic reason than polar ice melting for the higher ocean level -- the higher temperature of the water. Water is most dense at 4 degrees Celsius. Above and below this temperature, the density of water decreases (the same weight of water occupies a bigger space). So as the overall temperature of the water increases it naturally expands a little bit making the oceans rise.
In 1995 the Intergovernmental Panel on Climate Change issued a report which contained various projections of the sea level change by the year 2100. They estimate that the sea will rise 50 centimeters (20 inches) with the lowest estimates at 15 centimeters (6 inches) and the highest at 95 centimeters (37 inches). The rise will come from thermal expansion of the ocean and from melting glaciers and ice sheets. Twenty inches is no small amount -- it could have a big effect on coastal cities, especially during storms.

And that's the problem I have with science by press release.

Let's pretend that study is the only study ever done, and nothing else matters. What does it actually say when you fight your way past the hysterical press interpretation?

Here's what it actually says.

Quote:
Here we show that GICs, excluding the Greenland and Antarctic peripheral GICs, lost mass at a rate of 148 ± 30 Gt yr−1 from January 2003 to December 2010, contributing 0.41 ± 0.08 mm yr−1 to sea level rise...

The total contribution to sea level rise from all ice-covered regions is thus 1.48 ± 0.26 mm −1, which agrees well with independent estimates of sea level rise originating from land ice loss and other terrestrial sources6.
OK so it sounds like they took 7 of the 10 warmest years, and calculated that if ice continues to melt at the rate it did during these years sea level would rise 5.8 inches a century from ice melt alone.

So what?
