2448. Neal Stephenson on CO2
His new book is really good. From a recent interview
This seems like a sober assessment that can frame most of what we should be thinking .
The number that matters is the CO2 in the atmosphere, which is above 400 parts per million and climbing, That’s higher than it’s been in millions of years. So when we talk about emissions reductions, all we’re saying is that the rate at which that number grows, will slow down. But it’s still growing, the numbers still get higher every year. It’s just not climbing as fast because we reduced our emissions. If we could get to zero emissions, which might happen in a few decades -- like China’s saying maybe by 2060, it might get to zero emissions. That just means that that number stays wherever it is, for about a million years, which is how long it takes natural processes to remove it. So emissions reductions are great and zero emissions would be better than than not doing that, but still leaves us stuck with the number at a dangerously high level until we take active measures to remove that carbon dioxide from the atmosphere.From and interview
