An interview with James Hansen. Hero.
Catastrophic climate change can be averted, Hansen says, but only if we start “putting an honest price on the fossil fuels that includes their environmental costs, both their effect on human health, those costs being paid completely by the public, their effects in air pollution and water pollution, but also their effects on climate.”
He scorns the current “dishonest” cap-and-trade scheme. “You have to have a simple system which is transparent and which actually reduces the fossil fuel use. There’s really no value added by bringing the big banks into the problem. But with the cap-and-trade (system), the prices fluctuate and because there’s so much politics involved the prices can collapse, and so no one has any confidence in that system.
“And the banks of course”—he laughs—“JPMorgan Chase and Goldman Sachs, they have skilled trading units, hundreds of highly capable people who will make big dollars out of trades—but it adds nothing of value to the system, and where does that money come from? It doesn’t come out of thin air; it comes out of the public, the people, paying more for their energy. “
The so-called cap-and-trade “offsets,” which award carbon credits for preserving trees, “can be really hokey, really hard to verify—and they don’t actually pay attention to the physics of the problem, which tells you that the fossil fuel carbon that you put into the atmosphere will stay in the climate system for millennia. ... That means that there is a limit on how much fossil fuel you can burn. And they’re trying to trade other things in there as if they were equivalent to this fossil fuel carbon, but they’re not.”
Instead, Hansen favors a simple carbon tax or what he calls “fee and dividend,” with a rising surcharge on fossil fuels that is rebated in full to all taxpayers.
“The reason for the fee is simple—it really needs to be collected at the domestic mine or port of entry so that it’s just across the board—but unless you’re giving that money to the public, the public will never allow the fee to continue to rise because they will see the impact on the cost of gasoline at the pump and in their utility bills until there are some alternatives.”
The alternative that Hansen favors—a rapid worldwide expansion of nuclear power—is highly controversial among environmentalists, to say the least.
“I just published a paper with (fellow Goddard scientist) Pushker Kharecha, in which we point out the number of lives that have been saved by nuclear power. And that’s nuclear power of the early generations, 50-year-old technology. Even with that old technology, the accidents that did occur—the number of lives lost—was very limited in comparison to the number that are killed every year by coal, by the air and by water pollution from fossil fuel burning and fossil fuel mining. “
Hansen believes that new cooling systems and advanced reactor designs can answer concerns about accidents like the meltdown at Fukushima, Japan—“that’s solvable now”—and how to dispose of radioactive waste. “With a fourth generation of nuclear power, you can have a technology that will burn more than 99 percent of the energy in the fuel. It would mean that you don’t need to mine uranium for the next thousand years. We have got enough excess weapons material and nuclear waste to provide the fuel for many centuries.”
