Tamino examines a certain paper:
It’s certainly not true that their analysis shows “natural climate forcing associated with ENSO is a major contributor to variability and perhaps recent trends in global temperature.” It shows no such thing; their analysis removes all the effect of trends.
A thing to remember when you encounter McLean, de Freitas and Carter, being used as evidence that CO2 has no effect on temperature trends.
EDIT:
Bob Carter presents a press release:
The close relationship between ENSO and global temperature, as described in the paper, leaves little room for any warming driven by human carbon dioxide emissions.
END EDIT
The next natural question is, why on Earth did they write such crap? I have a hunch that it is also analyzed thoroughly on some blog somewhere, but I’ll leave finding that to the reader.
EDIT:
James Haughton commenting at Deltoid:
I think we should consider this paper not as a scientific publication but as part of a debating strategy. Certainly Carter (don’t know about the others) is smart enough to know that “Global warming stopped in 1998” is going to stop working as an excuse as soon as the next El Nino hits; which is likely to be this year. So he needs a fallback position. Therefore, he’s going to go from denying El Nino exists to claiming that all Global Warming is solely due to El Nino, which will enable him to get past the “hotter than 1998” problem.
