You do realize those 17 thousand scientists signed that petition 8 years ago, right?
"It is a petition signed by nearly 17,000 US scientists, half of whom are trained in the fields of physics, geophysics, climate science, meteorology, oceanography, chemistry, biology, or biochemistry."
"And without US participation, any plan to curtail CO2 emissions is doomed - as it ought to be."
Now that's an example of real journalistic excellence. Way to be objective.
Now for the actual website. The author is a biologist, who studies mushroom formation and yeast physiology, so obviously he is a credible expert on global warming.
Here are some quotes from his "about the author" page:
"There is only one cause of all problems, which is satan and the evil persons who he controls."
Not crazy at all...
"After getting significant results with mushrooms, I attempted to publish in the science journals but was locked out."
It sounds like he wants revenge on the scientific community for not publishing him.
Totally credible.
"CO2 disolving in water establishes an equilibrium. Equilibrium means absolute regulation.
Production and sequestration of CO2 are totally irrelevant, because they do not regulate."
This is not true. Production or sequestration of CO2 are not irrelevant, because if you add CO2, the equilibrium changes, shifting one way or the other. LeChatlier's Principle. That's fucking 10th grade chemistry.
I would also like this guy to explain this graph, with his claim that "The effect of so-called greenhouse gases such as carbon dioxide is extremely minuscule."
"Air has a much lower heat capacity than water, which means oceans can heat the air, but the air cannot significantly heat the oceans."
So, a glass of cold water will not eventually change to room temperature water. Right...
"The fact that there is so little variation in atmospheric CO2 over the centuries demonstrates that it is regulated."
Right, up until very recently.
Plus, his spelling and grammar reflect his level of professionalism very nicely.
"The see level gets about 400 feet lower over about 80 thousand years. Whether the oceans actually heat up for 80 thousand years, or whether the heat up of the oceans is just a trigger mechanism isn't clear."
