Losing the Public Debate On Global Warming

Hugh Pickens writes "Dr. James Hansen, director of the NASA's Goddard Institute for Space Studies, who first made warnings about climate change in the 1980s, says that public skepticism about the threat of man-made climate change has increased despite the growing scientific consensus. He says that without public support, it will be impossible to make the changes he and his colleagues believe need to occur to protect future generations from the effects of climate change. 'The science has become stronger and stronger over the past five years while the public perception is has gone in completely the other direction. That is not an accident,' says Hansen. 'There is a very concerted effort by people who would prefer to see business to continue as usual. They have been winning the public debate with the help of tremendous resources.' Hansen's comments come as recent surveys have revealed that public support for tackling climate change has declined dramatically in recent years. A recent BBC poll found that 25% of British adults did not think global warming is happening and over a third said many claims about environmental threats are 'exaggerated,' compared to 24 per cent in 2000. Dr. Benny Peiser, director of skeptical think tank The Global Warming Policy Foundation, says it's time to stop exaggerating the impact of global warming and accept the uncertainty of predictions about the rate of climate change. 'James Hensen has been making predictions about climate change since the 1980s. When people are comparing what is happening now to those predictions, they can see they fail to match up.'"

Re:The problem is chicken little

You have totally mischaracterised the debate. Most scientists aren't shouting about the end of the world -- but /some/ scientists are shouting about doing /something/ to mitigate against future risk. If there is a 10% chance of CAGW, and that can be reduced to 5% by investing 1% of resources now, then that is simply common sense. Heck, we spend 5% on the military budget.

But we cannot even talk about risk and risk-management, because as soon as you bring up the topic, "skeptics" accuse you of predicting the end of the world. This is just bullsh*t. Everyone has to feel the are right on whatever issue, even when they have to make up complete bulls*t.

As for AGW being "chicken-little", it is entirely plausible that there will be no ice-caps in 500 years time. It normally takes 10x that long or more for an ice-age to end. In just the next few decades, we will be hit in the wallet by insurance companies, who are already starting to factor in the costs of increased extreme weather events. The effects /may/ get worse at an exponential rate (say 10% chance), and lead to serious suffering -- even in the USA.

Actually, my knowledge of Greenland circa 1000AD is personal: In my undergrad days, I helped process samples from a Geology expedition to Greenland by two of my professors. Amongst the samples I cataloged were wood and tree branch sections, pulled out of the ice, and carbon-dated to ~990-1020 AD. Kind of hard to grow trees on the icecap. . . .
