we can fix climate change. will we?

We can do this. We should do this. If we we're too dumb to do this, well, think of it as evolution in action...maybe in a few tens of million years the next technological species to arise will get it right. As Krugman says, "All that stands in the way of saving the planet is a combination of ignorance, prejudice and vested interests. What could go wrong? Oh, wait."

Salvation Gets Cheap

But there is one piece of the assessment that is surprisingly, if conditionally, upbeat: Its take on the economics of mitigation. Even as the report calls for drastic action to limit emissions of greenhouse gases, it asserts that the economic impact of such drastic action would be surprisingly small. In fact, even under the most ambitious goals the assessment considers, the estimated reduction in economic growth would basically amount to a rounding error, around 0.06 percent per year.

What’s behind this economic optimism? To a large extent, it reflects a technological revolution many people don’t know about, the incredible recent decline in the cost of renewable energy, solar power in particular.
