I read that blog - http://ker-plunk.blogspot.com/ - there are a lot of blogs
like this endlessly recycling denier myths that have been shot down a
hundred times. Climateaudit.org or "Watts up with that" are much better
(although their comments sections are even more full of the fooled, the
gullible and the blinkered libertarians).
There are far too many half truths, exaggerations, misrepresentations and
false statements in the kerplunk blog to dissect here but amongst the two
biggest are the famous old "the hockey stick has been debunked" lie (it
hasn't - it really, really hasn't) and the slightly less famous tropospheric
temperature one.
Here is a reasonably up to date statement by the guy responsible for
analysing the measurements whose work USED to suggest that there was an
anomaly until they found the errors in their own work. The denier blogs and
propagandists seem reluctant to show the new info though...
"So where does that leave us? An "Executive Summary" by the U.S. Climate
Change Science Program, co-authored by John Christy of UAH concludes:
"Previously reported discrepancies between the amount of warming near
the surface and higher in the atmosphere have been used to challenge the
reliability of climate models and the reality of human induced global
warming. This significant discrepancy no longer exists because errors in the
satellite and radiosonde data have been identified and corrected. While
these data are consistent with the results from climate models at the global
scale, discrepancies in the tropics remain to be resolved.
This difference between models and observations may arise from errors
that are common to all models, from errors in the observational data sets,
or from a combination of these factors. The second explanation is favored,
but the issue is still open."
In other words, according to UAH, satellite measurements match the models
apart from in the tropics. This error is most likely due to data errors.
According to RSS, satellites are in good agreement with models. "
Most of the denier myths are exploded here (not the best, most definitive or
clearest but probably the largest number in one place)
