Paris Agreement architect: 2021 will dawn with hope – CNN

Yet five years on from that cold evening in Paris when I saw nearly 200 nations step up -- including the US with a delegation led by John Kerry -- this is no time for complacency. The period from 2010 to 2020 was the hottest period on record. Covid-19 has exposed our vulnerability to nature: the more we heat the planet and disrupt ecosystems, which causes disease-carrying animals and insects to relocate, the more vector diseases we will unleash. As 2020 draws to a close and Covid-19 vaccines mercifully come close, we can all reflect that no country is an island. Walls have limited utility against Mother Nature.

But reflecting back to five years ago, I see there has been a fundamental shift in people's understanding and expectations -- across all societies and sectors of action. There is widespread understanding that the climate crisis means net zero is the future we all have to go to. And citizens are demanding -- and voting for --this change.
