This is another post from him about the Shakun el al paper, 'Global warming preceded by increasing carbon dioxide concentrations during the last deglaciation', as reported in The Christian Science Monitor.
I have already posted on his immature treatment of this research and here he manages to under achieve compared to even that initial poor standard.
In his post he states;
"Antarctica … temperature increases … led … CO2"To the exclusion of all other data in the research. In the comments he insists;
"Shakun is not disputing the ice core data. Unless he can prove that ice core data is wrong his claims are as daft as you. "This research looks at a total of 80 climate proxies dating back to the last deglaciation as mapped in Figure 1 of the paper;
Because previous research had really only considered Antarctic proxies, (there are four considered in the paper), and showed temperate leading rising CO2 levels, Goddard refuses to accept the other 76 data sets because they are not telling him what he wants to believe.
Just to clarify his position, he is cherry picking just 5% of the data that confirms is ideological bias and is rejecting 95% of the data that might disagree with it!
I have now had a look at the full paper, (Thanks to Chris at Dosbat for the direct link), and the sequence of events that caused warming temperatures to lead CO2 in the Antarctic has been established.
Basically, Milankovitch cycles warmed the planet, just like the science has always said. This resulted in more Southern Hemisphere warming overall, which is why the Antarctic cores show warming first. This released CO2 from the oceans, which is why CO2 lags temperature in the Antarctic cores. The released CO2 was an additional driver of further warming, now globally, which is why the other proxies show this.
The basic science has not changed. Shakun’s paper just fills in some details, but clearly Goddard doesn’t want to understand the research.
For far better reviews of this paper instead of the rather simplistic view I have given here I recommend both Dosbat and Skeptical Science.
