Gaia's immune system is kicking in.

"the net loss of ice mass from Antarctica increased from 112 (plus or minus 91) gigatonnes a year in 1996 to 196 (plus or minus 92) gigatonnes a year in 2006."

Let us run some numbers. 112 +/-91 is a range of 21 to

203 gigatons. 196 +/-92 is a range of 105 to 288 gigatons.

So the actual mass may have increased by 98 gigatons, decreased by 267 gigatons, or anywhere in between

Let's assume the worst case plus some: 300 gigatons. Again assuming the worst case, let's also assume that most sci.electronics.design readers will live another

100 years. How much of a sea level rise is that? 100 gigatons of Antarctic ice is enough to raise sea level by 0.28 millimeters. 300 gigatons, 0.84 millimeters.

Over 100 years, 84 millimeters, or 3.3 inches. Worst case.

Best case, sea level drops 27 millimeters / 1.06 inches.

Best guess, sea level rises 23.5 millimeters / 0.91 inches.

If that is Gaia's immune system kicking in, Gaia has AIDS.

It's not an offset adjustment. We're adjusting the voltage for an oscillator with lousy power supply rejection.

The minor detail that the supposed signal is no larger than the acknowledged noise floor is revealing.

The nett loss of ice mass may be close to the noise floor, but the acceleration of the glaciers that deliver ice to the coast seems to be unambiguous.

The glaciers are moving faster because there is so much snow piling up on top of them that they're being pushed by the added weight.

Hope This Helps! Rich

And I thought I was the only one asking "so where is the global warming"....

Hopefully the Sun will get active again, I read somehwere about some

11 year cycle its spot activity has. Actually I heard this on the BBC worldservice, they said this was at its lowest now hence the thinnest ionosphere hence worst SW reception at the moment.

Here (Bulgaria) we also had a rarely long and cold winter, last week we got some warm anomaly - much to my relief, I really _hate_ the winter - hopefully it will last more than just another few days...

--Winter in Minnesota...

60 above zero: Floridians turn on the heat. People in Minnesota plant gardens. 50 above zero: Californians shiver uncontrollably. People in Duluth sunbathe. 40 above zero: Italian & English cars won't start. People in Minnesota drive with the windows down. 32 above zero: Distilled water freezes. The water in Bemidji gets thicker. 20 above zero: Floridians don coats, thermal underwear, gloves, wool hats. People in Minnesota throw on a flannel shirt. 15 above zero: New York landlords finally turn up the heat. People in Minnesota have the last cookout before it gets cold.

Zero: People in Miami all die. Minnesotans close the windows.

10 below zero: Californians fly away to Mexico People in Minnesota get out their winter coats. 25 below zero: Hollywood disintegrates. The Girl Scouts in Minnesota are selling cookies door to door. 40 below zero: Washington DC runs out of hot air. People in Minnesota let the dogs sleep indoors. 100 below zero: Santa Claus abandons the North Pole. Minnesotans get upset because they can't start the Mini-Van. 460 below zero: ALL atomic motion stops (absolute zero on the Kelvin scale.) People in Minnesota start saying..."Cold 'nuff fer ya?" 500 below zero: Hell freezes over. Minnesota public schools will open 2 hours late.

Brrr, -20C (-4F?) is as cold as it gets here, although there are even colder records (rare)... This year it actually never got below -12C or so (apr. 10F), but the winter began in October and showed no signs of retreat until a few days ago, hovered between -10 and -5 C for months. Are you one of these all-weather Minnesotans? I wish I were.... :-). Mind you, my morning shower is a cold-water shower (10-12C, normal tap water, plus as many screams as it takes), but prolonged cold is something which just gets me into panic... (or is it an Arctic syndrome, no clue :-).

Interesting hypothesis. They've pulled ice cores out of the Antarctic ice cap that go back half a million years ...

People who know what they are talking about are advancing other ideas.

I grew up in Minn., but have since immigrated to Sunny Southern California. ;-) I was noticing the other day, the temps were in the 60's, and people were bundling up with their hoods and scarves and stuff. Hell, if it hits 60 in February in Minnesota, they have a backyard barbecue!

Since immigrating, I've become all wimpy and can't stand the cold any more, just like a Californian. )-; (but I _do_ still know how to drive a car!)
