"The United Nations is poised to release the most confident and comprehensive
assessment yet of global warming, including detailed estimates of how continued
greenhouse-gas emissions will increase Earth’s sea levels and drive extreme
weather in the coming years. Compiled by more than 200 scientists and approved
by government representatives from 195 countries, the report from the
Intergovernmental Panel on Climate Change (IPCC) will leave little doubt that
humans are altering the way the planet functions — and that things will get
much worse if governments do not take drastic action, say climate researchers
interviewed by Nature.
Many hope that the report, which covers the latest advances in climate science,
will galvanize action at the UN climate summit in Glasgow, UK, this November,
where world leaders will make fresh commitments to curbing greenhouse-gas
emissions. Scientists say that on the basis of current policies, governments
will fail to meet the goals they set in the 2015 Paris climate accord to limit
global warming to 1.5–2 °C above pre-industrial levels.
“This report will make it absolutely clear what is the state of the science,
and throw the ball back in the camp of the governments for action,” says
Corinne Le Quéré, a climate scientist at the University of East Anglia in
It is the first in a trio of reports that will comprise the IPCC’s sixth major
climate assessment since 1990: a second report, on climate impacts and
adaptation, and a third, on mitigation efforts, will follow next year. In
anticipation of the first report’s release next week, Nature previews what
researchers say are some of the most significant advances in climate science
conducted since the last IPCC assessment eight years ago."
