Using satellite images, NASA has put together a short slide show

of the ice melting from Jan. 1 to Sept. 16, 2007. It can be found on

the below link to NASA. (1)

Waleed Abdalati, head of Goddard's Cryospheric Sciences Branch.

said \".... this year, the amount of ice is so far below that of previous

years that it really is cause for concern. The trend in decreasing ice

cover seems to be getting stronger and stronger as time goes on.\"

This information got some coverage in US corporate media, but

another report of research from a worldwide group of scientists did

not.

'DRAMATIC' CHANGE IN THICKNESS ALSO

Fifty scientists from Europe, USA, Japan, and China have been in

the Arctic for the past three months gathering data on the ice and

the environment. In 2001 the ice averaged six feet in thickness.

This year large areas of the ice are only three feet thick. (2)

“The ice cover in the North Polar Sea is dwindling, the ocean and the

atmosphere are becoming steadily warmer, the ocean currents are

changing” said chief scientist Dr Ursula Schauer, from the Alfred Wegener

Institute for Polar and Marine Research. “We are in the midst of a phase of

dramatic change in the Arctic....\" she said.

So What?

\"So the area of the ice is diminishing at an accelerated speed, and the

ice is now only half as thick as '01. What does that mean to me? I didn't

see much of a change in weather this year......maybe a few more floods

and such. But I don't get it! WHAT'S THE BIG DEAL? It seems to me

that I've got more important things to think about than a 1.4 degree F

temperature rise and some ice melting at the poles.\"

Well, the Arctic Ice does not contribute to rising sea levels since it is floating

in the ocean. But, and this is a huge distinction, it is fresh water - as opposed

to salt water. And since fresh water is not as dense as salt water, it has the

power to slow the thermohaline currents that distribute heat from the tropics

to the northern latitudes.

And it has been shown that many times in the past two million years the

climate has snapped into ice age conditions within as little as ten years

instead of the thousand year transition that we were all taught in elementary

school. If the climate hits that tipping point and the growing season is

shortened to six or eight weeks a year, there will be global famine. That is

a very real possibility and an extremely frightening one at that.
