Carbon dioxide emissions need to fall by the equivalent of a lockdown every two years to save the planet, climate scientists have claimed.
The claim derives from a paper in the journal Nature Climate Change titled ‘Fossil CO2 emissions in the post-COVID-19 era’.
According to the abstract:
Five years after the adoption of the Paris Climate Agreement, growth in global CO2emissions has begun to falter. The pervasive disruptions from the COVID-19 pandemic have radically altered the trajectory of global CO2 emissions. Contradictory effects of the post-COVID-19 investments in fossil fuel-based infrastructure and the recent strengthening of climate targets must be addressed with new policy choices to sustain a decline in global emissions in the post-COVID-19 era.
In short, the nations of the world will need to do much, much more if they are to meet the CO2emissions reduction targets set out by the Paris Climate Agreement. This is predicated on the idea that by keeping global industrial CO2emissions below a certain level, mankind will somehow tweak the global temperature control knob to such effect that planetary warming will be kept within a supposedly safe range of “1.5 °C to well below 2 °C.”
