Climate Change, Nukes, and Geoengineering

By Robin Hahnel.

On November third James Hansen signed an open letter addressed to environmental organizations urging them to demonstrate “real concern about risks from climate damage by calling for the development and deployment of advanced nuclear energy.”

Like Hancoolingtowersen and some notable long-time environmentalists who have recently come out in support of nukes, I am desperate. I am desperate because, like them, I know we we have very little time left to pull off the greatest technological “re-boot” in human history, turning global fossil-fuel-istan into global renew-conserve-istan before it is too late. That is why I recently sent my own open letter to those in the climate justice movement who argue that green capitalism is an oxymoron and climate change can only be solved by economic system change. In my view those who argue that greener capitalism is a false hope and not worth pursuing have no sense of time. They have no sense of how fast irreversible climate change is coming compared to how fast we can marshal support for economic system change. However, I find it sad that people like Hansen are caving on nukes when we do not need dangerous or new technologies to solve the problem. Continue reading…


Geoengineering: Don’t Ignore Economics and Governance

By Gernot Wagner Ph.D. Economist, Environmental Defense Fund

How serious is global warming? Here’s one indication: the first rogue entrepreneurs have begun testing the waters on geoengineering, as Naomi Klein laments in her must-read New York Times op-ed.

Sadly, Klein misses two important points.

First, it’s not a question of if but when humanity will be compelled to use geoengineering, unless we change course on our climate policies (or lack thereof). Second, all of this calls for more research and a clear, comprehensive governance effort on the part of governments and serious scientists – not a ban of geoengineering that we cannot and will not adhere to. (See point number one.)

Saying that we ought not to tinker with the planet on a grand scale – by attempting to create an artificial sun shield, for example – won’t make it so. Humanity got into this mess thanks to what economists call the “free rider” effect. All seven billion of us are free riders on the planet, contributing to global warming in various ways but paying nothing toward the damage it causes. No wonder it’s so hard to pass a sensible cap or tax on carbon pollution. Who wants to pay for something that they’re used to doing for free – never mind that it comes at great cost to those around them?

It gets worse: Turns out the same economic forces pushing us to do too little on the pollution front are pushing us toward a quick, cheap fix – a plan B.

Enter the Strangelovian world of geoengineering – tinkering with the whole planet. It comes in two distinct flavors: Continue reading…
