The Salt Lake Tribune – July 16, 2009

Article Excerpt: Tom Tripp, a member of the UN IPCC since 2004, is listed as one of 450 IPCC “lead authors” who reviewed reports from 800 contributing writers whose work in turn, was reviewed by more than 2,500 experts worldwide. (Tripp, a metallurgical engineer, is the Director of Technical Services & Development for U.S. Magnesium.) [...] Read the rest of this entry »

Comments On The Current Record Global Average Lower TroposphereTemperatures

From Climatesci.org  Roger Pielke Sr.

In the last couple of weeks, the onset of the El Niño, that was discussed on in my weblog on July 11 2009 would appear to be a possible explanation for the sudden increase in lower tropospheric temperatures to a record level (e.g. see the latest tropospheric temperature data at Daily Earth Temperatures from Satellite). This sudden warming is also discussed on other websites (see and see).

The current and recent anomalies at 500 mb (as representative of the tropospheric temperatures) are provided by the excellent NOAA analyses at

The location for the sudden warming (in the global average tropospheric temperatures as reported from the AMSU data) at 500 mb in the Northern Hemisphere is not obvious, however, except perhaps for a large area with weak positive anomalies in the lower latitudes. There is some warming in the El Niño area, but it is relatively small.  In the lower latitude eastern hemisphere In the southern hemisphere, there is a strong warm anomaly near Antarctica. Maybe that is part of the reason for major region for the large positive AMSU temperature value.

This record event is an effective test of two hypotheses. Read the rest of this entry »
