Many bloggers—including some from The New York Times—have been writing posts describing it is too late and too expensive to stop catastrophic climate change. That is false. Our globe will warm a bit; keeping it below the 2˚C mark is key. But it is not too late to keep our earth from substantial warming and it won’t be that expensive. The Intergovernmental Panel on Climate Change (IPCC) estimates that to keep our globe from warming more than about 2˚C will cost about .06 percent of global GDP—that is a mid range estimate, the high is around 0.14 percent—in investments in things like renewable energy sources, and more efficient forms of energy storage. With the potential to save farmable land, our ice caps, wildlife, and possibly millions of lives, it seems like the most lucrative investment ever offered to mankind.
