Your "we" includes every nation on Earth? Including China and India who have built many coal fired electricity plants lately, and have plans to build many more?

Your "we" includes every nation on Earth? Including China and India who have built many coal fired electricity plants lately, and have plans to build many more? Plants that have design lifetimes of ~40 years?
You expect to have all fossil fuel powered vehicles worldwide phased out within 20 years? Including aircraft? What about cargo ships?
There is no practical chance of even hitting the lowest trajectory IPCC target, much less something considerably below that.
- adrianN 7y agoWell then we probably shouldn't even try right? Just keep on accelerating towards that cliff.
- Recurecur 7y agoDid I say that? What does make sense is to do cost effective, beneficial, and non-sacrificial things. One of the best things overall is to promote next generation nuclear power as a major alternative to coal. If coal could be phased out entirely within 20-30 years that would be a huge win. Perhaps grid storage could largely replace gas generation. That would leave fossil fuels mainly in transportation, which would be a giant improvement over today. Lower CO2 trajectories give more time to rigorously evaluate the science, get more data, and develop revolutionary technology.
