Climate scientists living in Pollyanna world, says senator | smh.com.au

THE National Party senator Ron Boswell repeatedly clashed with some of Australia's leading climate scientists yesterday, accusing them of living in "a Pollyanna world" and putting jobs in jeopardy by calling for deep cuts to the country's greenhouse gas emissions.

"Jobs are on the line," Senator Boswell said. "You've got to be practical".

Professor Stewart Franks, from the University of Newcastle, told the hearings that the UN's scientific evidence on human caused climate change was "all rubbish".

Michael Barone - On Climate and Health, Beware of Easy Formulas

Consider carbon emissions. Carbon dioxide is a harmless gas, not a pollutant. But geeks bearing formulas tell us that increasing amounts of it will heat up the world's climate and cause catastrophic damage some decades hence. Al Gore is so certain of this that he tells us all debate must end; disagreeing is like denying the Holocaust.

But the Holocaust happened, while the disasters that Gore predicts have not. When you try to predict climate, you are dealing with even more factors and more unknowns than when you try to predict financial risk. Prudent people will want to hedge against some risks that seem possible. But imposing huge costs on the private sector economy--raising the price of electricity for everybody--solely on the basis of some geeks' formulas seems, well, not prudent. But that's what Barack Obama tells us we must do.

U.S. Sen. Charles Grassley (R-Iowa) weighs in

When asked what the government was doing about global warming Grassley replied, “The concept is still a little fuzzy to me. I have to weigh all the evidence. But I do believe we can do something even if not absolutely sure.”

He said scientists are still disputing whether the cause is natural or man made.

But either way he said he believes the answer lies in making an international treaty. “The United States can not do this alone,” he said. He said other large industrial countries, such as India and China, also need to play a part in the solution.
