The problem however is it shows us that unprecedented shutting down of the economy has an effect below that needed to tackle climate change. https://www.scientificamerican.com/article/why-co2-isnt-fall...

The figure I saw quoted is an estimated yearly reduction due to global lockdown of around 5% for CO2 emissions where about 7.5% yearly reduction is needed.

This isn't necessarily a cause for doom and gloom but it does show we need to move the focus back to transport, energy generation, etc and away from personal responsibility which on its own has minor benefits.

Incredible how we react when we might die in 2 weeks instead of 50 years...

But the lockdown also shows the problems of shutting down the economy; in developing nations day wagers are starving and dying. In developed nations frothing-in-the-mouth idiots are protesting with their semi-auto weapons.
