Yeah, that's what all the tobacco industry "scientists" said about studies on the effects of smoking.

Of course, his statement would be considered "inconclusive at best" wouldn't it?
The evidence that there is warming globally is factual, and the globe has been warming since the end of the last ice age around 11,000 years ago. Climate however is not static and there have been may times in the recent past when the temps were warmer then they are currently. The most recent was the Medieval Warming Period and the Roman Warming Period before that.
At both times global temperatures were warmer (England for example was able to compete with France in wine production, something they could never hope to do at the current time) and Romes culture bloomed during their warming period.
The claims for anthropogenic global warming on the other hand are tenuous at best. No prediction they have ever made has actually come to fruition. In fact quite the opposite has occured.
Below is an exchange between two of the main players in the AGW cabal please note the highlighted remarks. That is not science my friend, that is political advocacy.

your words are a real boost to me at the moment. I found myself questioning the whole process and being often frustrated at the formulaic way things had to be done - often wasting time and going down dead ends. I really thank you for taking the time to say these kind words .
I tried hard to balance the needs of the science and the IPCC , which were not always the same. I worried that you might think I gave the impression of not supporting you well enough while trying to report on the issues and uncertainties .
Much had to be removed and I was particularly unhappy that I could not get the statement into the SPM regarding the AR4 reinforcement of the results and conclusions of the TAR. I tried my best but we were basically railroaded by Susan*. I am happy to pass the mantle on to someone else next time. I feel I have basically produced nothing original or substantive of my own since this whole process started. I am at this moment , having to work on the ENV submission to the forthcoming UK Research Assessment exercise , again instead of actually doing some useful research ! Anyway thanks again Mike.... really appreciated when it comes from you very best wishes

Keith, just a quick note to let you know I've had a chance to read over the key bits on last millennium in the final version of the chapter, and I think you did a great job. obviously, this was one of the most (if not the most) contentious areas in the entire report, and you found a way to (in my view) convey the the science accurately, but in a way that I believe will be immune to criticisms of bias or neglect--you dealt w/ all of the controversies, but in a very even-handed and fair way. bravo! I hope you have an opportunity to relax a bit now. looking forward to buying you a beer next time we have an opportunity
