So... COVID-19 lock-downs have reduced travel so much that CO2 emissions have fallen a huge amount ! Air travel is virtually non-existent (where have they parked all the planes??) and road travel has taken a huge hit too.
This has resulted in the largest-ever recorded fall in CO2 emissions - that's about 1.6 Billion tonnes of CO2, or 4% of global emissions. Very impressive !!
Except that - according to carbonbrief.org - to achieve the required cap on temperature rises to avert a climate catastrophe (i.e. 1.5°C above pre-industrial levels), we need an annual reduction in CO2 emissions of 6% for the foreseeable future (until 2050?).
How are we going to achieve these reductions? It seems we need to put the world economy on hold for about 4-5 months every year !!!
So to avoid blasting ourselves back to the stone age via catastrophic climate change, we have to blast ourselves back to the stone age via economic ruin.
We're screwed.
