Christine Figueres, who must be given great credit for delivering the Paris Agreement has launched a new initiative – Mission 2020. Mission 2020 is not a new NASA moon shot, but is a new initiative to bring "new urgency" to the "global climate conversation". Inherent in Mission 2020 is a call to begin "rapidly declining" global greenhouse gas emissions by 2020. In a letter in the journal, Nature Mrs Figueres and 61 co-signatories (which include climate scientists as well as a range of NGO, religious, political and business leaders) set out their stall that the next three years will be crucial. They argue that if emissions can be brought permanently lower by 2020(not just held static as they have for the last three years) then the temperature thresholds leading to runaway irreversible climate change will not be breached.

An admirable goal let's hope that all Governments around the world listen and more importantly take urgent action to reduce their greenhouse gas emissions.
