Keep in mind that this is really just a nicer-sounding way of saying that we get xxx-xxxx (can't be arsed to do the half-life based math at the moment) years worth of equivalent C02 warming in just 8 years. Given how global warming is accelerating toward/through various points-of-no-return, stopping to point out that it's 'only' 8 years is doing a disservice to the efforts of communicating the danger of our current situation.
