James Hansen is the author of ‘The Storms
Of My Grandchildren: The Truth About
The Coming Climate Catastrophe And
Our Last Chance To Save Humanity.’
He’s been a climate scientist for NASA
and was the first scientist to testify before
Congress about climate change. In the
book, Hansen wrote about climate change,
‘We seem oblivious to the danger, unaware
how close we may be… to our demise.’
Lester Graham talked to Hansen and noted
that we don’t often hear strong language
like that from scientists:
Dr. James Hansen: Well, the public is unaware of the situation, and that’s partly because of the way nature works. You know, weather is highly variable – 10 or 20 or 30 degree variations are common – while the global warming, so far, is about 1 degree Celsius, which is about 2 degrees Fahrenheit. So, people have a hard time seeing it. But the consequences are already becoming apparent, as we see with the melting sea ice in the arctic. The Northwest Passage is now actually open. Mountain glaciers melting around the world, sub-tropics expanding – which is affecting the Southwest United States and the Mediterranean region and Australia. And the problem is that those things are going to grow, and we’re going to pass tipping points, which will have disastrous consequences if we pass them. We don’t have to pass them though. And that’s why it’s appropriate for us to try to communicate the situation to the public, because the kinds of things that we need to do with our energy systems make sense anyway for different reasons.
Lester Graham: The evidence for climate change is growing – almost every week more studies are released, often indicating the future will be worse than first thought. What do you think we need to do to minimize the effects of climate change?
Dr. Hansen: Well, it’s very clear what we need to do. The carbon dioxide is increasing because of the burning of fossil fuels. If you look at how much carbon there is in oil, gas, and coal, you see that coal is, by far, the biggest reservoir. And then there’s the unconventional fossil fuels, like tar shale and tar sands. What we need to do is phase out the coal use and prohibit the use of these unconventional, dirty fossil fuels – and we could solve the problem. But to get there, there’s a very practical requirement, and that is that we begin to put a price on carbon emissions. The reason that people use fossil fuels as their main source of energy is that it’s the cheapest energy. And, as long as that’s the case, we’re going to keep using more and more. But the reason that they’re the cheapest is that we subsidize them – our government subsidizes them – and they don’t make them pay for the costs that they cause for society. The human health problems due to air pollution and water pollution, the mercury and the arsenic that comes from coal, and the costs of future climate change for our children and grandchildren – all of these are free for the fossil fuel companies. They don’t have to worry about those at all. The way we would solve that is to put a gradually rising price on carbon emissions. And there’s actually some good news in the newspaper, and that is that Senators Kerry, a Democrat, and Lindsey Graham, a Republican, announced that they’re not going to push cap-and-trade – which had been the big banks’ proposed solution to put a ‘cap’ on carbon emissions, and then they, you would (chuckles) – it was a complicated system where you could trade the rights to pollute. But the big winners would be the traders and the losers would be the public.
James Hansen is a climate
scientist for NASA and the author of the
book, ‘Storms Of My Grandchildren.’ He
spoke with The Environment Report’s
Lester Graham. We’ll hear
more from Dr. Hansen tomorrow, including
his idea on how to reduce using fossil fuels.
