A global warming limit agreed by world leaders with great fanfare has come close to being broken just eight months on, it is reported. Climate change scientists have warned it may be nearly impossible to keep global warming below the 1.5˚C target set at the Paris negotiations in December after temperatures peaked at 1.38˚C above pre-industrial levels in February and March.
Met Office data analysed by Reading University professor Ed Hawkins showed average global temperatures were more than 1˚C over for every month except one over the past year, The Observer reports.
The Intergovernmental Panel on Climate Change (IPCC) is due to meet in Geneva this month to outline how the Paris deal, which slashed the limit from 2˚C to 1.5˚C, will be implemented.
However co-chair of the IPCC working group on adaptation to climate change, Stanford University Professor Chris Field, told the newspaper staying below 1.5˚C looked ‘impossible or at the very least, a very, very difficult task’.
Targets for bringing an end to the use of coal-powered fire stations and the combustion engine are reported to be on the likely agenda in Geneva.
Dr Ben Sanderson, of the National Centre for Atmospheric Research in Boulder, Colorado, suggested that it would take a global effort with such measures on an unprecedented scale to keep the target – a ‘tall order’.
Professor Jim Skea, a member of the UK government’s committee on climate change, said ‘negative emission technology’ would have to play a part by actively removing carbon dioxide from the atmosphere.
So-called ‘carbon capture’ techniques include extracting the gas from the air, liquefying it and storing it underground.
The current temperature trends reveal an overall upward climb in average global temperatures around the world.
While there are pockets of localised cooling, data from climate agencies confirm that surface temperatures are increasing.
Last month, the gulf state of Kuwait recorded scorching temperatures of almost 54˚C (129˚F), one of the highest on record.
The past year has seen a string of record breaking monthly temperatures in succession, with experts confirming a shift in Earth’s average climate.
