James Hansen is a great man.
In this wide-ranging talk he addresses young people saying they need to lead a peaceful revolution to create a new political party that will support science and reason, a carbon tax, and renewed investment in nuclear energy.
He argues that we are at a historic low point of leadership. All parties, left and right, are clueless and ineffective. Hansen has hope for political change because he has seen young people influence elections, and because he has seen in his younger years good leaders that did the right thing, even in the absence of popular support.
Hansen sadly concludes by saying to young people, “sorry to leave you such a friggin’ mess”, but unfortunately it’s up to you to fix it.
Hansen struggles a little in the talk, perhaps because he is tired, or perhaps because despite having worked hard to warn citizens about the dangers of climate change since 1981, every indicator and action by society continues to move in the wrong direction.
As an aside, I think Hansen makes a serious error by stating that a carbon tax will be effective without damaging the economy. A carbon tax will indeed reduce CO2 emissions, but it will also reduce our standard of living, as will any effective climate change policy. He should state this clearly to avoid a dangerous backlash when the truth emerges.
With regard to nuclear energy, it really is the only option that might maintain our modern technology, and I say might because it does not replace our vital diesel. I personally think the risks are unacceptably high that nuclear can be kept safe with proper maintenance and governance as civilization becomes simpler, poorer, and chaotic due to overshoot, the depletion of affordable oil, and the end of growth. But reasonable people could disagree on this, especially people who think modern technology should be retained as a top priority.
