"On the other hand, there's not a single thing we can do to stop global cooling: just bundle up, stay indoors and try to survive the cold weather and high food prices."

Not true. There are any number of things. Release lots of stable fluorocarbons (HUGE greenhouse gas effect). Deposit soot (black)in snow-covered areas to change the albedo. Melt the sub-sea methane clathrates to increase atmospheric methane (another very strong greenhouse gas). Build space-borne mirrors to concentrate more solar energy. Burn lots of coal. I suspect there are many others.

Hmmmmm, interesting. All of that stuff combined could have some effect. But if we had a major ice age similar to the one that sent glaciers all the way into present-day America and carved out the Great Lakes, somehow I think our efforts would be overwhelmed by the lack of solar energy reaching earth. But it all depends on how big the greenhouse effect really is from CFC's, CO2, etc. We're still building our knowledge of the greenhouse effect and nobody knows for sure whether these gases really generate a greenhouse effect and how strong that effect is.

"This cooling reverses an oceanic-warming trend observed since the 1950s, oceanographer John M. Lyman and his colleagues report in the Sept. 28 Geophysical Research Letters".

Ya know, these guys are putting their jobs on the line to publish this stuff.
