From the blog of Roger Pielke Sr. http://climatesci.org/
An excerpt reads,
“The stakes at Copenhagen could not be much higher. Global surface temperatures have risen by a tolerable three quarters of a degree celsius over the past century, but the rate of increase is accelerating. The Kyoto Protocol has had negligible impact on greenhouse gas emissions, and projections for the mean global temperature rise in the next century range from 1.1 to 6.4 degrees. Whether fast or very fast, the Earth is heating up.
There will be continued argument about the science of climate change over the next 12 months, but not, except on the conspiratorial fringe, about the threat. Climate change is real and worsening, and there is an overwhelming likelihood that much of it is man-made.”
This is a erroneous report on the climate system! The rate of increase is NOT accelerating. There is absolutely no question that global warming has stopped for at least 4 years (using upper ocean data) ; e.g see
Pielke Sr., R.A., 2008: A broader view of the role of humans in the climate system. Physics Today, 61, Vol. 11, 54-55.
and over 7 years using lower tropospheric data; e.g. see
Figure 7 TLT in http://www.ssmi.com/msu/msu_data_description.html.
With respect to the surface temperature trends [which have a warm bias in any case, as we have documented in our peer review papers; e.g. see], a good set of analyses on this subject has been posted over the last few years at http://rankexploits.com/musings/ [you should scroll back over the last several months to view; it is an excellent comparison with model predictions]. As discussed on that website, even with the warm biased global average surface temperature trends, the models have over-predicted warming. The GISS data itself even shows recent cooling in the ocean sea surface temperatures [see their figure for Monthly-Mean Global Sea Surface Temperature; http://data.giss.nasa.gov/gistemp/2008/ where it has cooled since 2002.
The writers of the Time article, and other journalists who write similar misinformation, damage the liklihood of responsible environmental actions as a result of their overstatement and erroneous communication to the public and policymakers of climate science.
