More heat to come this year and next

Man-made global warming is set to produce exceptionally high average temperatures this year and next, boosted by natural weather phenomena such as El Nino, Britain's top climate and weather body said in a report on Monday.

"It looks very likely that globally 2014, 2015 and 2016 will all be among the very warmest years ever recorded," Rowan Sutton from the National Centre for Atmospheric Science, which contributed to the report, told journalists.
