Item #3 for building back better

We are unlikely to return to the same state of the world as when we entered the #pandemic, nor is this desirable. #Remoteworking has the potential to become more prevalent after the crisis. 2/4
Investments might shift from face-to-face working (and lower the cost of #officerealestate and time for #commuting).

Item #2 for building back better

The covid crisis must be used to accelerate the transition to an electric, zero-carbon economy, to reduce climate tail risk. 2/4
This includes:

(a) investments in renewable energy (and maybe nuclear, if it can be made fast and safe) for powering the industry;

(b) electrification of trains, trucks, public transport, and cars; and

1/4 #Nuclear power plants are bespoke, slow to build, and fat tailed for financial and safety risks. #Wind farms and #energystorage are modular, fast, and thin tailed. 2/4 By choosing wind over nuclear, the risk of regression to the tail will be significantly reduced, and #climate goals will be achieved sooner. This is just one example. Many others exist.

1/4 Rebuilding the economy after covid-19 will be subject to the law of regression to the tail, if less dramatically than the pandemic. Loss of life will hopefully fade as a main risk.

#Floods and #wildfires are both subject to regression to the tail. The same holds for #droughts, #hurricanes, #landslides, #icemelt, #sealevelchange, and other phenomena closely related to the climate crisis. Image This tells us that understanding regression to the tail and how to mitigate its specific manifestations for climate will be key to mitigating the climate crisis.
