Saturday night I sent the Tweet you see below because, once again, there are people who are criticizing Dr. Michael Mann’s “hockey stick” research that shows today’s climate is warmer than at any time in the past 2000 years. The latest attempt to discredit Mann’s work comes from Dr. Judith Curry’s post titled Fraudulent(?) hockey stick where she writes “accusations of data cherry picking and flawed statistical analyses and interpretations seem to be justified. ” Dr. Curry and others should know that the hockey stick curve shows up in other research even when using different types of data and different types of data analyses. (I blogged about this in 2010 with Shooting the Messenger with Blanks.)
Enter Paul Clark (@cbfool). His three main points were:
- Hockey sticks are based on tree rings and tree rings are unreliable
- Ice core data from Greenland shows the past was much warmer than today
- Greenland in the 1200s was more conducive to agriculture than today so it must have been warmer than today
Sigh. I knew it was going to happen eventually. It is a shame that the science deniers are much better organized than the rational people. As of 8 AM this morning, Dr. Michael E. Mann’s latest book The Hockey Stick and the Climate Wars: Dispatches from the Front Lines had 15 reviews, all of which were 5 stars. My review (posted below) had 58 out of 59 votes for being helpful.
Enter climate science denier Anthony Watts whose blog has never missed an opportunity to smear a climate scientist. This morning, Watts posted about Mike Mann’s new book and within hours the Amazon reviews turned ugly. Of course, Watts tells his readers “While I realize that many people don’t want to buy this book, please don’t pull a Peter Gleick and do reviews apparently in absentia.” referring to his false claim that National Academy of Sciences member Dr. Peter Gleick posted a 1 star review of Donna Laframboise’s book without reading it. I also read that book and it deserved the 1 star. Watts has a history of doing this.
As of 7 PM EST tonight there are now eleven 1 star reviews and all of the 5 star reviews are being sabotaged by vote downs and negative comments. My detailed review is suddenly not helpful – only favored by 87/172 people. The top 1 star review is highlighted below:
Wow! This reviewer packs quite a few climate myths into the first paragraph. Can you say Dunning-Kruger? The debunking of these myths can be found by visiting Skeptical Science’s Arguments page and clicking on #71, #6, and #12.
These bad reviews and vote downs are an obvious hit job on Dr. Mann’s book by Anthony Watts’ anti-science minions. Sadly, the persecution of Mann continues and that is why people need to read this book. After reading one will see that this childish attack on the Amazon review system is just the tip of the iceberg for those who find scientific facts to be inconvenient.
