- All new cars have to be electric by 2030. Currently, electrical cars are at around 1%, at least in the US. To go from 1% to 100% in 13 years would be one of the most amazing accomplishments ever. How many people do you know that even have a purely electrical car? Now imagine that everyone you know has one…
- Carbon capture has to get to five gigatons per year by 2050. In other words we have to be removing 5 billion tons of carbon dioxide from the atmosphere and putting it somewhere where it can’t escape. Currently, as best I can tell we are doing effectively zero carbon capture right now. But, by 2050, the article says, we would have to be capturing twice as much carbon as all the trees and soil on the entire planet.
- In addition to perfecting carbon capture, there are a host of other technologies we’d have to invent. In particular we have to come up with a low carbon way for producing steel and concrete. We’d have to grow food with zero carbon emissions from land use. We’d have to make a huge investment in nuclear energy or invent much more effective batteries.
- Finally we have to cut carbon dioxide emissions in half every decade. Currently the US, China and India are responsible for half of all emissions. Imagine that all three countries had to be completely carbon neutral by 2030. And then of course you have to halve it again in 2040, and then you have to halve it again by 2050.
