Warm Atlantic Water Rapidly Replacing Arctic Sea Ice

[Louisiana1976]

snip

Warm, salty Atlantic ocean water normally enters the Arctic to replace water that flows out of the Arctic through the Fram Strait along the east coast of Greenland. However, that normal process has greatly accelerated this fall allowing Atlantic Ocean water to penetrate much further into the Arctic Ocean than normal.

1. Not good.

I read a couple of years ago about the deep current "ocean conveyor" that is crucial to both ocean and atmospheric conditions.

Warm currents versus cold currents keep it moving, and if global warming evens out ocean current temperatures, it will seriously screw up a lot of things. Can't remember the details now, but it's very serious.

2. Yep, the northerm hemisphere could freeze over.

3. We're about due for anothe ice age anyway right?

8. In a thousand years or two

not in the next decade, which is what could happen if the oceans desalinate significantly.

9. Give or take a thousand years or two

Fact is science doesn't really know what will cause the next glaciation, or when it will start. Now 2k years from now or some that believe we have another 20k years.

5. Wonderful.

Isn't that a trip? Global warming could mean a new ice age.

No wonder most people don't get it. It's definitely a head scratcher for people who don't "do" science.

4. predicted in the disaster movie "The Day After Tomorrow" ....

6. Oops!

Not to worry, though - I'm sure I've got some press releases about a planned clean-coal plant lying around here somewhere.

And, if all else fails, a vigorous application of emails will make everything fine.

7. I don't even want to read stuff like this anymore...

We're so screwed.

10. And there is another one of the melting modes.

We are going to see more of them.

11. I remember a thermodynamics course

The discussion was energy conversion using temperature difference. Some jackass entrepreneur had the notion he would use barges to tow a large section of arctic ice to a convenient location. Looking back to those years, I have to laugh. Actually, I though it was a stupid fucking idea even back then.
