COVID-19 – Effetti collaterali

Di Jeff Tollefson

In sintesi: gli effetti della pandemia COVID-19 nel 2020 includono un calo di emissioni di CO2 pari al 6.4% a livello globale, e del 13% negli USA.

Questo calo è inferiore a quanto previsto dai climatologi e ovviamente si prevede che le emissioni di biossido di carbonio torneranno a salire non appena la pandemia ci darà tregua.

After rising steadily for decades, global carbon dioxide emissions fell by 6.4%, or 2.3 billion tonnes, in 2020, as the COVID-19 pandemic squelched economic and social activities worldwide, according to new data on daily fossil fuel emissions. The decline is significant — roughly double Japan’s yearly emissions — but smaller than many climate researchers expected given the scale of the pandemic, and is not expected to last once the virus is brought under control.
