Data and evidence don't stand a chance against beliefs.

Anthony Watts lost any right to make claims..

If you read it very closely you'll realise that Anthony Watts makes no claims whatsoever.
The letter was not written by Anthony Watts, but by 49 scientists and astronauts.

I'm motivated to stay out of senseless debates. Not sure why I answered in the first place thus my deleting my posts. Enjoy your discussion.

49 former NASA scientists and astronauts sent a letter to NASA Administrator Charles Bolden last week admonishing the agency for it’s role in advocating a high degree of certainty that man-made CO2 is a major cause of climate change while neglecting empirical evidence that calls the theory into question.

The group, which includes seven Apollo astronauts and two former directors of NASA’s Johnson Space Center in Houston, are dismayed over the failure of NASA, and specifically the Goddard Institute For Space Studies (GISS), to make an objective assessment of all available scientific data on climate change. They charge that NASA is relying too heavily on complex climate models that have proven scientifically inadequate in predicting climate only one or two decades in advance.

Select excerpts from the letter:

• “The unbridled advocacy of CO2 being the major cause of climate change is unbecoming of NASA’s history of making an objective assessment of all available scientific data prior to making decisions or public statements.”
• “We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated.”
• “We request that NASA refrain from including unproven and unsupported remarks in its future releases and websites on this subject.”
• With hundreds of well-known climate scientists and tens of thousands of other scientists publicly declaring their disbelief in the catastrophic forecasts, coming particularly from the GISS leadership, it is clear that the science is NOT settled.

Actually, I'd love to join in. I will as soon as we talk about science. 'I don't agree with this statistical test', 'I think the imprecision of the data cannot be dealt with using
interval arithmetic', 'I think the p-value is borderline and we cannot conclude'...Then we can have a discussion...

Maybe CO2 isn't causing these effects, if not then what? All of the "What's" I've seen have been pretty much proven to not be the cause.
