Per restare sotto 1,5 gradi di riscaldamento dai livelli pre-industriali è necessario tagliare di almeno il 50% le emissioni di gas serra al 2030, ed azzerare le emissioni nette al 2040.
È questo l'appello lanciato stamani alla COP26 di Glasgow dal rapporto "Le 10 nuove nozioni nella scienza climatica", presentato dai centri studi internazionali Future Earth, the Earth League e World Climate Research Programme.
"Questo rapporto mostra che stabilizzarci su 1,5 gradi è ancora possibile, ma solo se soluzioni drastiche ed immediate vengono adottate - ha detto Wendy Broadgate, direttrice di Future Earth -. I leader mondiali alla Cop26 devono porre obiettivi aggressivi per la riduzione delle emissioni. Nulla che non si avvicini al 50% di riduzione delle emissioni al 2030 e a zero emissioni al 2040 è sufficiente".
