The October 2020 World Economic Outlook report, from the International Monetary Fund IMF, warns that current emissions policies are grossly insufficient, and that “Without further action to reduce greenhouse gas emissions, the planet is on course to reach temperatures not seen in millions of years, with potentially catastrophic implications.”

Renewables or Nuclear? Which is a better path to decarbonisation?

Banks lent trillions of dollars in 2019 to finance ecologically destructive activities. The Guardian article on 28-10-2020 summarises a recent report.
China’s 2015 NDC (its pledge to the 2015 COP21 Paris climate conference ) promised only to “lower carbon dioxide emissions per unit of GDP by 60% to 65% from the 2005 level”. Its 2020 revision to its NDC was a lot more ambitious: its emissions would peak by 2030, and decline to zero by 2060. The UK is committed to reaching zero emissions by 2030.
