Denial ain't just a river in Egypt

Denial ain't just a river in Egypt.
Mark Twain

Yesterday's paper reported that a study done by a University of Texas science team monitoring a satellite mission that measures the Earth's gravity over the entire Greenland ice cap as the ice melts and the water flows down into the Arctic ocean has found the three miles thick cap is melting faster than ever before on record. And the pace is speeding up year by year. The consequence is already evident in a small but ominous rise in sea levels around the world, the scientists say.

"We have only been watching the ice cap melt during a relatively short period," physicist Jianli Chen said, "but we are seeing the strongest evidence of it yet, and in the near future the pace of melting will accelerate even more." The same satellites are also monitoring the melt rate of Antarctica's ice cover, and there too the melting is adding to the rise in sea level.

Greenland has the second largest reservoir of fresh water on Earth and holds about 10 percent of the world's supply. The increasing flow of fresh water is beginning to change the composition of the ocean's salt water currents flowing past Northwestern Europe said the scientists.

The result could be a critical change in the composition of the main ocean current that flows past Europe's northern edge, blocking off warmer waters and making Northern Europe's weather colder than normal, at least temporarily, while the rest of the globe continues warming.

Al Gore writes about this also in "An Inconvenient Truth."

"I flew over Greenland in 2005 and saw for myself the pools of meltwater covering large expanses on top of the ice... These pools have always been known to occur, but the difference now is that there are many more of them covering a far larger area of the ice. This is significant because, as Dr. McCarthy (of Harvard University) points out, they are exactly the same kind of meltwater pools that he and other scientists observed on top of the Larson-B ice shelf (in Antarctica) in the period before its sudden and shocking disappearance.

"In Greenland, as in the Antarctic Peninsula, this meltwater is now believed to keep sinking all the way down to the bottom, cutting deep crevasses and vertical tunnels that scientists call "moulins."

"When the water reaches the bottom of the ice, it lubricates the surface of the bedrock and destabilizes the ice mass, raising fears that the ice mass will slide more quickly toward the ocean."

Pictured is a moulin- "...a masive torrent of fresh meltwater tunneling straight down to the bedrock below the ice. Notice, for scale, the scientists at the top of the picture."

So when is Bush's government going to wake up and smell the coffee and sign the Kyoto treaty limiting emissions ?

We need to start acting now or there will be no planet left for grandchildren to be.

This administration will never sign that treaty. It's against everything they stand for.

The lights of Cairo are lovely from the river as you gaze through the smog.

There is a difference between a good BJ and a bad BJ.

the picture is oddly beautiful

the consequences - hell at this point we have no idea if we can stem the tide, let alone reverse it.

Gore may not have been the most charismatic politician, but at least he's putting the reality out there for all of us to see.

unfortunately, i doubt any profound action will be taken

great post - thanks

You cannot conceive the many without the one.

Ten years. The reputable scientists say we have ten years.
If you haven't already, read Gore's book, or see the movie.
It is his opening salvo for '08.

I always thought there was this weird irony to the term "Fossil Fuel."

maybe in millions of years, after our near extinction, we'll become fuel for our descendants' vehicles.
irony abounds, doesn't it?

And we continue to live our lives because "its not happening to us.. it's all the way over there.."

:: sigh ::

One day it will be a harsh lesson for us all..

Oh, but it is happening here. Look at the record breaking heat. Look at Katrina, a hurricane that practically destroyed an American city. Look at the changing rain patterns. People just can't put it together, because they aren't given all the facts.

.....get your arc ready....

the rate the underground volcano...in yellowstone lake...is growing ..we might be thinking of another modus operandis
