The disturbing thing is that the the tilt could see-saw — at least for places like Denmark which rely upon the Gulf Stream to give us a milder climate that we deserve so far north.
It’s not so much the Artic ice cap but the degradation of the Greenland ice which could affect the Danes (and other northern Europeans).
The Autumn and Winter here have busted all records for both warmth and precipitation — even so, we have had snaps of bitter cold, frost and snow –odd.
The theoretical “tipping point” or threshold scientists often talk about is such an abstract concept for a general public that is very reactionary at best.
Even though more and more people now are starting to believe that we are causing global warming, not everyone understands the science behind the positive feedback loops we need to know in order to avoid a global catastrophe. We cannot wait until the Artic ice shelves melts entirely before we take drastic measures, nor can we wait until half of the shelves melt away. By then, we would have crossed the ‘tipping point’ by 50 years or so.
I’m so grateful to Common Dreams as a resource to keep me abreast of the way that the media is covering these crucial issues.
There was an earlier article in CD about the break up of the Ayles Ice sheet of of Ellesmere Island which I should have mentioned in my first comment:
http://www.commondreams.org/headlines06/1230-06.htm
Indeed, as Viper says, “tipping point” maybe doesn’t conjure up a picture like “the straw that breaks the camel’s back” or “point of no return” — but it is more meaningful perhaps than “positive” or “negative feedback loops”.
However, some people really don’t want to know what is coming down the tube as long as “they got theirs” here and now.
I discussed the “Crack of Doom” more detailed here:
