Climate Tipping Points

In case you have missed this today, please read Debate on Climate Shifts to Issue of Irreparable Change. There is increasing concern that we are approaching “tipping points” beyond which global warming becomes irreversable and the climate rapidly shifts, with each effect increasing the warming even more.
One example of a tipping point is the potential for fresh water coming from ice melting in Greenland disrupting the North Atlantic current. This would bring the average temperature of Europe down by about 9 degrees in a few years. This happened about 8,200 years ago. Current estimates for the odds of this happening again are at 50 percent.

  1. I don’t think there’s any question any longer about us being on the cusp of major climate changes, or about our role in causing this. The only remaining scientific questions seem to be the extent to which this might be part of a natural cycle we’re making much worse than it would otherwise be. There isn’t going to be anything gentle or nice about it; it was established at least a generation ago that ice ages, for example, only required about 70 years to develop.

  2. Geo W. lives about 2 miles away from me. It’s going to be 60 degrees out again today, as it has been off and on for most of January. We’ve been having warmer winters each year. Weather has been going wacky all over the world.
    At some point doesn’t common sense trump friends in the oil industry?
