Watts Up With That?

Over at World Climate Report, the indefatigable Pat Michaels and Chip Knappenberger review a new study updating National Climate Data Center (NCDC) data on U.S. State climate extremes. I’ll cut right to the chase. The paper, “Evaluating Statewide Climate Extremes for the United States,” published in the Journal of Applied Meteorology and Climatology, finds that far more State-wide all-time-high temperature records were set in the 1930s than in recent decades.

From Pat and Chip’s review:

Despite the 24/7 caterwauling, only two new state records—South Carolina and Georgia—are currently under investigation. And, looking carefully at Shein et al. dataset, there appears to be a remarkable lack of all-time records in recent years. This is particularly striking given the increasing urbanization of the U.S. and the consequent “non climatic” warming that creeps into previously pristine records. . . .

Notice that the vast majority of the all-time records were set more than half a century ago and that there are exceedingly few records set within the past few decades. This is not the picture that you would expect if global warming from greenhouse gas emissions were the dominant forcing of the characteristics of our daily weather. Instead, natural variability is still holding a strong hand.

The chart below shows the number of State heat records and the year in which they were set. (When the same all-time high occurs in two or more years in the same State, each of those years gets a fraction of one point.)

Did the Medieval Warm Period (MWP) and Little Ice Age (LIA) occur only in Europe, or were they global in scope?

This is a hotly debated question, because it is harder to make the case that the warmth of recent decades is “unusual,” “extraordinary,” or “unprecedented” and therefore something to stress about if global climate oscillates naturally between warming and cooling periods. The catastrophic anthropogenic global warming (CAGW) crowd tend to write off the MWP (~1000-1200 A.D.) and LIA (~1300-1850 A.D.) as regional phenomena, largely confined to Northern Europe. A new study finds evidence of the MWP and LIA in a region 10,000 miles south of Northern Europe: the Antarctic Peninsula. [click to continue…]

Anthony Watts’s indispensable Web site, Watts Up with That?, has a trove of hard-hitting commentaries on climate scientist Peter Gleick’s theft and publication of the Heartland Institute’s fund-raising documents and apparent forgery of a “confidential” climate strategy memo. Gleick earlier this week confessed to stealing the documents, but not to fabricating the strategy memo, although textual and other evidence point to him as the culprit.

Gleick, who described his conduct as a “serious lapse of my own and professional judgment and ethics,” has resigned from his post as Chair of the American Geophysical Union (AGU) Task Force on Scientific Integrity. He nonetheless tried to blame the victim, claiming “My judgment was blinded by my frustration with the ongoing efforts — often anonymous, well-funded, and coordinated — to attack climate science and scientists and prevent this debate, and by the lack of transparency of the organizations involved.”

Yep, it’s the small underfunded band of free market think tanks who are stifling the U.N. Intergovernmental Panel on Climate Change, the U.S. Global Change Research Program, the National Academy of Sciences and their numerous brethren overseas, the European Environment Agency, the U.S. Climate Action Partnership, the EPA, NRDC, Greenpeace, etc. etc. Heartland invited Gleick to attend a public event and debate climate change just days before he stole the documents. Gleick turned down the invitation. Yet Gleick has the chutzpah to plead “frustration” at those trying to “prevent this debate.”

Among the key posts on Anthony’s site to check out: Joe Bast’s Skype interview with the Wall Street Journal; Dr. Willis Eschenbach’s Open Letter to Dr. Linda Gunderson, who succeeds Gleick as Chair of the AGU Scientific Integrity Task Force; and Megan McCardle’s column in The Atlantic reviewing among other things evidence fingering Gleick as the author of the fake strategy memo.
