Wong as wrong on sea as on air February 4, 2010Posted by BlueGreen in Deception, Doesnt Understand, Misrepresentation.
When I’ve mentioned, too, that the warming has paused since at least 2001, global warming believers have often preferred not to believe it, or even to see it. But Fielding, with a power to block the Government’s emission’s trading scheme in the Senate, could not be fobbed off. So Climate Change Minister Penny Wong and her advisors had to give him a formal answer.They still say there’s been an overall warming trend since 1998 (technically true, I believe, but certainly not true of the years since 2001) but imply that any more recent cooling doesn’t count:
(A)t time scales of around a decade, natural variability can mask the atmospheric warming trend caused by the increasing concentration of greenhouse gases.
But, more importantly: When climate change scientists talk about global warming they mean warming of the climate system as a whole, which includes the atmosphere, the oceans, and the cryosphere… (I)n terms of a single indicator of global warming, change in ocean heat content is most appropriate.
So all that talk about hotter temperatures at this city or that town? Just kidding. The goalposts are now switched. The real measure is in fact the rise in temperature in the oceans. Which, you’d assume from Wong’s response, is real and alarming.
The first of the many “cooled since 1998” or “cooled since 2001” arguments which is falsely repeate by Bolt ad nauseum:
The planet has continued to accumulate heat since 1998 – global warming is still happening. Nevertheless, surface temperatures show much internal variability due to heat exchange between the ocean and atmosphere. 1998 was an unusually hot year due to a strong El Nino.
The lack of hard-and-fast linear increase of global temperature with time has never been an AGW axiom and is patently obvious form the time series of globla temperature. Andrew Bolt must know this or else he just does not understand the science.
In the very article Bolt links to:
Trenberth and Willis agree that a few mild years have no effect on the long-term trend of global warming. But they say there are still things to learn about how our planet copes with the heat.
