Staying under 1.5 is a fantasy.
If we want to stay under 3 we’d better get some real effort behind ending coal as soon as possible.
While it is possible to do more than one thing at a time, our politicians are trying to plug a leak while ignoring a giant gaping hole just around the corner. It’s like they’re incompetent morons or something.
- bryanlarsen 3y agoOTOH, I used to have lots of people tell me that it would be almost impossible to stay under 5 degrees of warming. Landing at about 3 degrees of warming is substantially better than many of the scenarios laid out in the past. I'm still optimistic we can stay below 2 degrees of warming.
- DennisP 3y agoWe absolutely should end coal as soon as possible, along with oil and natural gas. We should also develop and scale methods for pulling CO2 back out of the atmosphere. Just ending emissions avoids the worst outcomes but still leaves us with a bad outcome. If politicians were not incompetent morons then we could have solved the problem a lot sooner without having to pull CO2 back out of the air, but here we are. Also, there are some applications, like long-haul jets, that will be very difficult to electrify, and DAC gives us a way to make liquid hydrocarbons for them without any net emissions. Biofuel is another way in theory, but not always in practice, and it takes a lot more land area.
