Steve Enos posted a comment on an AP Story by Seth Borenstein “Statistics Experts Reject Global Cooling Claims”
here. Seth has know to write misleading climate change reports in the past, this one on
Sea Surface Temperature is just one example. Now we are treated to yet another misleading article. Dr. Roger Pielke at Climate Science has some thoughts on the Borenstein AP article:
Comments On AP Story “Statistics Experts Reject Global Cooling Claims”There is a news report titled “Statistics experts reject global cooling claims” by Seth Borenstein which appeared today. The article reads
“WASHINGTON — The Earth is still warming, not cooling as some global warming skeptics are claiming, according to an analysis of global temperatures by independent statistics experts.
The review of years of temperature data was conducted at the request of The Associated Press. Talk of a cooling trend has been spreading on the Internet, fueled by some news reports, a new book and temperatures that have been cooler in a few recent years.
The statisticians, reviewing two sets of temperature data, found no trend of falling temperatures over time. And U.S. government figures show that the decade that ends in December will be the warmest in 130 years of record-keeping.
Global warming skeptics are basing their claims on an unusually hot year in 1998. They say that since then, temperatures have fallen — thus, a cooling trend. But it’s not that simple.
Since 1998, temperatures have dipped, soared, dropped again and are now rising once more. Records kept by the British meteorological office and satellite data used by climate skeptics still show 1998 as the hottest year. However, data from the U.S. National Oceanic and Atmospheric Administration and NASA show 2005 has topped 1998.
“The last 10 years are the warmest 10-year period of the modern record,” said NOAA climate monitoring chief Deke Arndt. “Even if you analyze the trend during that 10 years, the trend is actually positive, which means warming.”
Statisticians said the ups and downs during the last decade repeat random variability in data as far back as 1880.”
This article, however, (which is not a true independent assessment if the study was completed by NOAA scientists) is not based on the much more robust metric assessment of global warming as diagnosed by upper ocean heat content. Nor does it consider the warm bias issues with respect to surface land temperatures that we have raised in our peer reviewed papers; e.g. see and see.
