Actually, in Alaska for the past century most glaciers have been receeding, but a few have been growing.  And I won't address the "galloping" or "surge" glaciers.  If I remember my arctic geography class correctly, glacier length is determined more by the amount of snowfall at the top, than the melting at the bottom.  The more weight on top, the faster they move, so the longer they get.  Since arctic regions tend to get more snow during warmer winters, they're really a questionable indicator of temperature, like tree rings.  Besiides, over all the glaciers have been slowly receeding since the end of the last ice age, 12,000 years ago.

Coincidently, one of the theories I've heard on the ice age cycle maintains that warmer temperatures trigger the next ice age.  The theory goes that as temperatures increase, polar region snowfall also increases, more and more water get locked up in ice.  Eventually the ocean levels drop to a point where polar precipitation exceeds tropical evaporation and the amount of water vapor in the atmosphere begins to drop.  Since water vapor is responsible for 95% of the earth's green house effect temperatures drop very rapidly into the next ice age.

Incidently, the recently completed Antartic coring reports showed some very interesting things.  One is that the warm periods between ice ages always correspond with higher CO2 levels, but points out that the cause/effect relation isn't clear since warmer temps produce greater natural CO2 production.  Also of interest is that Ice ages always last 60 to 70 thousand years, while the warm periods between only last 10,000 years.  With one exception, there was one temerate period in the study that lasted 28,000 years.  It corresponded with the earth's axis relative to the sun the same as it is currently.  If that wasn't the case, we'd have plunged into the next ice age about 2,000 years ago.  Imagine for a min. what that would have done to modern civilization.   :o

It'd be really ironic after all the work we'll be doing in the next few decades to prevent Global Warming if we actually enter the next ice age.

he he... that sounds like a line from Jack Handy "Deep Thoughts" . .

Do you know him?
From SNL?

i.e.

" It takes a big man to cry . . .
 . . . but it takes a bigger man,
to laugh at that man."

Yeah, I nearly always laughed out loud when those came on SNL.  Since that was before the Internet went commercial, I can't abbreviate that to LOL.   ;)

That reminds me of something else.  Without giving away enough details to get me in too much trouble,  you have to be careful if you want to open up a thermos of hot cofee at altitude if it was almost boiling down low, since that might be above boiling at altitude and leave you with a thermos boiling over when you open it!   (no it wasn't me)

Two people jumped from a plane into a lake and were unhurt, and the pilot landed with the floats off which I think would leave struts sticking down and the plane landed on grass and the pilot wasn't hurt? Yes that's weird, nice but weird.

In the immortal words of online gamers everywhere...WTF??
The average pilot, despite the sometimes swaggering exterior, is very much capable of such feelings as love, affection, intimacy and caring. These feelings just don't involve anyone else.

I was just reading the newspaper this morning (one of the several free copies you find in the underground in London) and it's written that by far, this has been the hottest autumn since....1757 or something like that. it's umbelievable, but even if I do not go out anymore just with a pullover, a light jacket is still enough and no scarf is needed here......
and wonder what? inside the metro you see some panels where the gov advises the people about turning down the lights in the house and the equipments, in order to spare money and energy, so that the pollution reverses. and........I'm currently living near several government buildings: and the transport and traffic agency (or whatever it's called) is a 8 or something store's building. nobody is inside from 5.30 in the afternoon and the lights of the building are ALL on, during the night, for a total of 24 hrs a day.

Ps. sorry for my english, but I must be quite tired and I cannot come out with a better style! :)
I give that landing a 9 . . . on the Richter scale.
