Or half as quickly – woteva. Isn’t it odd that all the errors and dodgy sources in the IPCC report conspired to make the climate change problem bigger, badder, “worser” than previously thought? Wouldn’t you think that roughly half the errors would show it “worser”, and half would show it not “worser”? If you were cynical, you might even conclude that such dodgy sources and errors were included because, oh, I don’t know, the authors had some pre-conceived agenda to push? OK, sarcasm off. But today’s “inconvenient headline” (thanks to Paul at The Daily Bayonet), which comes from the UK Daily Mail, reports that things in the melting ice cap department aren’t quite as bad as previously believed:
The Greenland and West Antarctic ice caps are melting at half the speed previously predicted, it has been announced.
Scientists measured the change in the ice caps by analysing changes in Earth’s gravitational field using two satellites, which monitor the distribution of mass on Earth including ice and water.
When ice melts and joins the sea, this has a small, but detectable effect on the Earth’s gravitational field.
This finding has emerged from research by a joint US/Dutch team from the Jet Propulsion Laboratory, Delft University.
The average rise in sea levels as a result of the melting ice caps is also lower, the team discovered.
Previous estimates for the Greenland ice cap calculated that the ice was melting at a rate of 230 gigatonnes a year – 230,000 billion kg. That would result in an average rise in global sea levels of around 0.75 mm a year.
For West Antarctica, the estimate was 132 gigatonnes a year. However, it now turns out that these results were not properly corrected for glacial isostatic adjustment.
This phenomenon relates to the rebounding of the Earth’s crust rebounds [sic] as a result of the melting of the massive ice caps from the last major Ice Age around 20,000 years ago.
These movements of the Earth’s crust have to be incorporated in the calculations, since these vertical movements change the Earth’s mass distribution and therefore also have an influence on the gravitational field.
Researchers have now succeeded in carrying out that correction far more accurately. (source)
Makes a change, dunnit? A bit of good news. Once again, it just goes to show how utterly nonsensical it is for anyone to say about climate change “the science is settled.”
