(deliberate pun in title) Michael Mann has been interviewed by yet another journalist who didn’t do the background reading. Read it all at Mother Jones Roger Pielke has done a good job of exposing the politicization of climate science on the Prometheus blog. I think its very wrong to equate a view on a particular […]
Of all news outlets across the world, the supposedly unbiased BBC has been one of the greatest cheerleaders of global warming alarmism in general, and the Hockey Stick in particular. My encounters with the journalists who write on the BBC website have been brusque and condescending. As a mere taxpayer and license fee payer, I […]
Briffa’s Tornetrask temperature reconstruction is done by regression analysis. Previously I reported that Briffa purported to justify his upward adjustment of 20th century MXD chronology (and downward adjustment of MWP reconstruction) by a very slight improvement of R2 (going from 0.503 to 0.553 – see Clim. Dyn 1992). I’ve attempted to replicate these regression calculations […]
Wild et al. [2001], a blue-chip study, shows that the downward longwave radiation in cold, dry climates is dramatically under-estimated in the GCMs used in IPCC TAR, as shown in the following excerpt from their Figure 4 (from one of the best GCMs). The bias is systemic. FIG. 4. Annual cycles of model-calculated and observed […]
Since 2000, there have been a number of very important new studies, increasing the estimated NIR absorption parameters of water vapor, stimulated by the discovery of the HITRAN-96 clerical errors, but amounting to significant increases over and above those errors. The increases seem to account for much missing atmospheric absorption. Again, the issue here is […]
I thought it would be interesting to look up more details of presentations made by people at the recent conference in Canberra. I found some materials at this site. Of more relevance to the research of Steve McIntyre is this presentation by Dr Bob Carter of the James Cook University on the question of climate […]
By 1999, systematic errors in the HITRAN-96 database for NIR water vapor absorption (which oppose water vapor feedback!) had been identified and widely reported by the most eminent authorities. For example, Systematic errors have been found and corrected in the HITRAN (High Resolution Transmission Molecular Absorption Database) water vapor line absorption intensities in the visible […]
I notice that some posters have been discussing water vapor feedbacks and thought that I’d chip in a little. One aspect of water vapor’s role in the climate system that I find intriguing is absorption of near infrared (NIR) and visible solar radiation by water vapor. This is a topic of very active research by […]
As one of our correspondants has pointed out, there was a conference on global warming attended by skeptics in Canberra, recently: The Sydney Morning Herald reports: Although heavily outnumbered, global-warming sceptics believe the stakes are so high they must step up their fight, as Michael Duffy reports. Members of a species widely believed extinct – […]
ORIGINAL: A little while ago I mentioned that the original SI at Nature for MBH98 had been deleted. It contained some information which is not in the Corrigendum SI, such as RE statistics for the various steps and the original (incorrect) data listing. Now Mann has either deleted the UMass SI for MBH98 and MBH99 […]
