Experts admit global warming predictions wrong
The worst impacts of climate change can still be avoided, senior scientists have said after revising their previous predictions.
The world has warmed more slowly than had been forecast by computer models, which were ?on the hot side? and overstated the impact of emissions, a new study has found. Its projections suggest that the world has a better chance than previously claimed of meeting the goal set by the Paris agreement on climate change to limit warming to 1.5C above pre-industrial levels.
The study, published in the journal Nature Geoscience, makes clear that rapid reductions in emissions will still be required but suggests that the world has more time to make the changes.
Michael Grubb, professor of international energy and climate change at University College London and one of the study?s authors, admitted that his past prediction had been wrong.
He stated during the climate summit in Paris in December 2015: ?All the evidence from the past 15 years leads me to conclude that actually delivering 1.5C is simply incompatible with democracy.? He told The Times yesterday: ?When the facts change, I change my mind, as [John Maynard] Keynes said. It?s still likely to be very difficult to achieve these kind of changes quickly enough but we are in a better place than I thought.?
The latest study found that a group of computer models used by the Intergovernmental Panel on Climate Change had predicted a more rapid temperature increase than had taken place. Global average temperature has risen by about 0.9C since pre-industrial times but there was a slowdown in the rate of warming for 15 years before 2014.
Myles Allen, professor of geosystem science at the University of Oxford and another author, said: ?We haven?t seen that rapid acceleration in warming after 2000 that we see in the models. We haven?t seen that in the observations.? He added that the group of about a dozen computer models, produced by government institutes and universities around the world, had been assembled a decade ago ?so it?s not that surprising that it?s starting to divert a little bit from observations?. Too many of the models used ?were on the hot side?, meaning they forecast too much warming.
