West Antartica Ice Melt Now "Unstoppable": NASA

I ran thru this thread.....did anyone say....?
There could be a snap back effect.

The sudden rise of temperature melts the glacier and polar ice.
This slows the water flow of the ocean.
The displacement of heat performed by the flow deteriorates.
The water vapor in the atmosphere and the lack of flow in ocean current then shield the Earth from the sunlight.

The surface could then quick chill.

The Earth would turn into a snowball.

We wouldn't live long enough to see the full effect.

But I did see it mentioned on a science program.....
The Earth was only 7degrees cooler when New York was under an mile of ice.

In the previous century the green house gases raised the temperature by 3degrees in less than 50years.
At his rate, the Sahara will continue to grow 1mile every year.
The tropical zone will increase north and south 1mile every year.
Many coastal major cities will be flooded before I die.

I been thinking about Sunstone's post and I realized something. Al Jazeera never sites or links to the study it refers to (I tried to find it in the article). But I think I read this misleading report that A J is using as proof just last week. The report never states that the glaciers are melting, just that this would happen if the glaciers ever melted (duh-uh). The report also stated the this "catastrophic" melting would take hundreds of years to produce any noticeable effect. This is just another example of of GW disciples using alarmist speculation instead of hard evidence to support their tenuous arguments (and Heavens know that Al Jeezera would never lead us down the garden path).

In the first place, it's been all over the news -- not just in Al Jeezera. Simply Google West Antarctic Ice Sheet Melting to find articles from various sources.

For instance, here's some quotes from a New York Times Article:

Times said:
A large section of the mighty West Antarctica ice sheet has begun falling apart and its continued melting now appears to be unstoppable, two groups of scientists reported on Monday. If the findings hold up, they suggest that the melting could destabilize neighboring parts of the ice sheet and a rise in sea level of 10 feet or more may be unavoidable in coming centuries.

Global warming caused by the human-driven release of greenhouse gases has helped to destabilize the ice sheet, though other factors may also be involved, the scientists said.

The rise of the sea is likely to continue to be relatively slow for the rest of the 21st century, the scientists added, but in the more distant future it may accelerate markedly, potentially throwing society into crisis.

“This is really happening,” Thomas P. Wagner, who runs NASA’s programs on polar ice and helped oversee some of the research, said in an interview. “There’s nothing to stop it now. But you are still limited by the physics of how fast the ice can flow.”

Two scientific papers released on Monday by the journals Science and Geophysical Research Letters came to similar conclusions by different means. Both groups of scientists found that West Antarctic glaciers had retreated far enough to set off an inherent instability in the ice sheet, one that experts have feared for decades. NASA called a telephone news conference Monday to highlight the urgency of the findings.

>snip<

&#8220;Today we present observational evidence that a large sector of the West Antarctic ice sheet has gone into irreversible retreat,&#8221; Dr. Rignot said in the NASA news conference. &#8220;It has passed the point of no return.&#8221;

Those six glaciers alone could cause the ocean to rise four feet as they disappear, Dr. Rignot said, possibly within a couple of centuries. He added that their disappearance will most likely destabilize other sectors of the ice sheet, so the ultimate rise could be triple that.

Well, it doesn't look like you are going to get waterfront property anytime soon, Phil.

Why, no. I think I'll go ask the bus driver to diagnose my latest malady. I'm sure he has enough anecdotal experience to be a doctor.

But if you don't trust the countless scientists who say it's happening, who the frack are you trusting? If you don't trust someone seeing the Antarctic with their own eyes, changing, melting, who the frack are you going to trust?

You make no sense. :sorry1:

I don't trust the ones making the failed predictions, eg, increased hurricane & tornado frequency.
I do trust the ones collecting data on what actually is occuring, eg, climate change, glacier melting.
There is clearly a looming problem.

Has anyone mentioned?....'An Inconvenient Truth'.....

A report about global warming.
Al Gore narrates.

I wish I still had a link to an excellent article I once read. Maybe someone else has it.

What it amounted to was a team that took a bunch of spots around the globe. They indexed each one for temps and precipitation over time. 20 years I think. What they were graphing was the deviation from the norm over time. Cooler/warmer and wetter/drier. Over time the average changed slowly but the amplitude of the deviation s is growing dramatically. In other words, the average is not changing so much as the extremes. That is the problem with climate change. More heat means more activity means more extreme weather events.

Supposing just for the sake of argument that there is such a thing as catastrophic global warming (or unicorns, for that matter), please show where someone has given the actual temperature difference in plain numbers so even a construction worker can understand it.

Even better, I'll show you something super simple that anyone can understand:

I'm not going to reply to you after this. There's no point.

How about the Navy's ability to surface a sub at the north pole....
any time of year?

Used to be the winter months made that difficult.
Now they can break the ice almost at will.
