As one final note, here is even easier data to read.

Editorial: Hansen is simply wrong and his hypothesis is a complete and abject failure
On January 25, 2011, Rep. Henry Waxman sent a letter to Rep. Fred Upton seeking to call in Michaels for questioning about his science and funding. In the letter, Waxman wrote that Pat Michaels testified before the Energy and Commerce Committee in February 2009 "that widely accepted scientific data had 'overestimated' global warming and that regulation enacted in response to that data could have 'a very counterproductive effect.' Among the scientists who testified before this Committee on the issue of climate change in the last Congress, Pat Michaels was the only one to dismiss the need to act on climate change ... Dr. Michaels may have provided misleading information about the sources of his funding and his ties to industries opposed to regulation of emissions responsible for climate change."
On July 27, 2006 ABC News reported that a Colorado energy cooperative, the Intermountain Rural Electric Association, had given Michaels $100,000. An Associated Press report said that the donations had been made after Michaels had "told Western business leaders ... that he was running out of money for his analyses of other scientists' global warming research" and noted that the cooperative had a vested interest in opposing mandatory carbon dioxide caps, a situation that raised conflict of interest concerns.
According to Fred Pearce, fossil fuel companies have helped fund Michaels' projects, including his World Climate Report, published every year since 1994, and his "advocacy science consulting firm", New Hope Environmental Services.
This is not a published, peer reviewed criticism. .
Ahh, esteemed scientific journal "wattsupwiththat.com"
Any given viewpoint on science - heck, on ANY issue - is going to have detractors. You shouldn't listen to just one 'expert' on any subject. I can find you 10 PhDs who say vaccines cause autism, and 10,000 who say there's no data to support that claim and plenty to suggest it's untrue. You have to look for the consensus viewpoint. You're not really qualified to say whether cigarettes cause cancer or don't, and neither am I. If one doctor says they don't, and posts a complicated study, it's still stupid to pretend the conclusion is now seriously in doubt and you're fully justified puffing away three packs a day. "After all," I'm sure you'd argue, "all the other studies saying cigarettes cause cancer are just bought-and-paid-for stooges wanting government grants and to advance their careers! Damned liberals!"
The bitching about "Oh he's just trying to get government grants, let's wait for unbiased science" is absurd and shows complete ignorance of how science works. There is no such thing as a purely unbiased scientist working outside of the funding system, certainly not in fields that require significant amounts of money for serious studies. This, again, is why we don't take one study as a good reason to take action, but we DO put weight in meta-studies that compile and analyze many studies operating over a long time, such as the one from the OP. Science is the best way of learning about the world around us that exists, but it's not perfect or flawless and no scientist is an inhuman reason-robot giving perfect conclusions, so it's stupid to think that you've disproven a study by showing that a lead scientist is a human being with human motivations too. That's why we have extensive training for PhDs, peer review to analyze their methodology, and meta-studies so that no one study gets too much weight.
There more than likely is something to the global warming but I will wait till we start have some real un-biased studies by people not out for government grants or book deals and by people who are not going to change their opinion a few years later or exaggerate the numbers for effect.
IMO, we should not impliment potentially economy damaging rules when the economy is so fragile AND when our understanding of climate is so limited. We should study HOW the climate works until we actually understand it, THEN make recommendation on what do to about it.
Right now, politically controlled science is making recommendations without actually understanding how climate works. That is stupid, and potentially dangerous.
