England is facing a "significant and substantial increase" in record-breaking hot years because of man-made climate change, scientists claim.
Last year central England experienced the hottest year on record.
Now researchers have used computer modelling and analysis of historical records to show that the chances of record-breaking warm years have become much more likely as a result of human activity.
The modelling revealed that human influence made it 13 times more likely there would be a hot year like 2014 in central England, according to the study by the researchers published in the journal Environmental Research Letters.
Dr Andrew King, from the ARC Centre of Excellence for Climate System Science at the University of Melbourne, who led the study, said: "Both our approaches show that there is a significant and substantial increase in the likelihood of very warm years occurring in central England."
