...I'm the science reporter for the Houston Chronicle, the daily newspaper in the petrochemical capital of the United States, if not the world. I've been called a global warming skeptic by environmentalists, and I've been called an environmentalist toady by the skeptics. I'm neither of these things. Rather, I'm just trying to grasp what is happening to the planet's climate, and how humans are impacting it. For a long time now, science reporters have been confidently told the science is settled. That the planet is warming and humans are unquestionably the primary cause. We've been told to trust the computer models -- the models which show a markedly upward trend in temperatures as carbon dioxide concentrations increase. And I've trusted the scientists ...the key point here is that scientists are acknowledging that natural variations are playing a very important role in our present and future climate, perhaps cooling it. Therefore it stands to reason that natural variations might also have played a role in the temperature run-up of the 20th century. Do not misunderstand me. I am not a climate change skeptic. I do not deny that the planet warmed 0.6°C in the 20th century. I do not deny that humans played some part in that significant warming.
But I am confused. Four years ago this all seemed like a fait accompli. Humans were unquestionably warming the climate and changing the planet forever through their emissions of carbon dioxide. The problem is that some climate scientists and environmentalists have been so determined to see something done about carbon dioxide emissions -- now -- that they have glossed over the uncertainties....more from Eric Berger here...
...and it is this dogmatism, inspired by political ideology not science that will bring the AGW house down...
