Worst-case global heating scenarios may need to be revised upwards in light of a better understanding of the role of clouds, scientists have said.
Recent modelling data suggests the climate is considerably more sensitive to carbon emissions than previously believed, and experts said the projections had the potential to be “incredibly alarming”, though they stressed further research would be needed to validate the new numbers.
Modelling results from more than 20 institutions are being compiled for the sixth assessment by the United Nations Intergovernmental Panel on Climate Change, which is due to be released next year.
Compared with the last assessment in 2014, 25% of them show a sharp upward shift from 3C to 5C in climate sensitivity – the amount of warming projected from a doubling of atmospheric carbon dioxide from the preindustrial level of 280 parts per million.
This must be true. For as it has become increasingly obvious that RCP 8.5 is not true, cannot be true and has never been true how are we going to keep panicking the proles unless we change some other parameter to ensure that disaster looms?
After all, industrial civilisation is the enemy, everything else just an excuse.
There is just the one little fly in this ointment:
The IPCC is expected to include the 5+C climate sensitivity figure in its next report on the range of possible outcomes. Scientists caution that this is a work in progress and that doubts remain because such a high figure does not fit with historical records.
As it doesn’t explain what has happened it’s not a great deal of use in trying to explain what will now, is it? Weird that so many adults are fixated on the fantasies of a teenage girl but there’s no accounting for sexual tastes.
