Climategate: The Fallout Continues from CRU Hacking - Environmental Capital - WSJ

The big issue: Just how reliable is the information that is at the heart of the climate center’s conclusions about global temperature trends?  The CRU, for its part, stresses that
“our conclusions correlate well to those of other scientists based on the separate data sets held by the National Oceanic and Atmospheric Administration (NOAA) and the NASA Goddard Institute for Space Studies (GISS).”

A Myth About The Surface Temperature Record Analyses Perpetuated On Dot Earth By Andy Revkin « Climate Science: Roger Pielke Sr.

On the weblog Dot Earth today, there is text from Michael Schlesinger, a climatologist at the University of Illinois, that presents analyses of long term surface temperature trends from NASA, NCDC and Japan as if these are from independent sets of data from the analysis of CRU. Andy Revkin is perpetuating this myth in this write-up by not presenting the real fact that these analyses draw from the same original raw data. While they may use only a subset of this raw data, the overlap has been estimated as about 90-95%.

Climategate: Penn State Professor Mann under investigation

My question: What does this say for the integrity of their entire department? It is hard to imagine that Mann was the only person involved in manipulating the data at Penn State. What other faculty, and perhaps even grad students were part of the scheme?

Past regional cold and warm periods linked to natural climate drivers

ScienceDaily (Nov. 30, 2009) — Intervals of regional warmth and cold in the past are linked to the El Niño phenomenon and the so-called "North Atlantic Oscillation" in the Northern hemisphere's jet stream, according to a team of climate scientists. These linkages may be important in assessing the regional effects of future climate change.

"Studying the past can potentially inform our understanding of what the future may hold," said Michael Mann, Professor of meteorology, Penn State.
