The most recent global warming assessments from the Intergovernmental Panel on Climate Change
(IPCC) released in August 2021, warns that human activity has caused an approximate 1.1°C of
global warming above pre-industrial levels and that warming is likely to reach 1.5°C by between 2030
and 2040 if there is not a rapid shift to reduce emissions.
Nevertheless, successive Emissions Gap Report assessments (latest December 2020) from the UN
Environment Programme point to global warming of more than 3°C by the end of the century based
on current national emissions reduction commitments. To limit the increase in global average
temperatures to 1.5°C, emissions need to halve by 2030, and drop to net zero by the middle of the
century for the best chance of avoiding the worst environmental, economic and human impacts of
climate change.
