Global warming speeds up due to Pacific 'flip'
"The end of the recent slowdown in global warming is due to a flip in Pacific sea-surface temperatures," said Adam Scaife, head of climate predictions at the Met Office.
"After a period during the early 2000s when the rise in global mean temperature slowed, the values in 2015 and 2016 broke records and passed 1 degree Celsius above pre-industrial levels," said Stephen Belcher, chief scientist at the Met.
At a conference in Paris in late 2015, governments agreed a plan to phase out fossil fuels this century and shift to renewable energies such as wind and solar power. A study published Monday in Nature Geoscience suggests that in order to meet the 1.5 C target, global emissions after 2015 must be limited to 240 billion tonnes of carbon. That would require serious emissions reductions, but the good news is that it's a much bigger limit than the IPCC's estimated limit of 70 billion tonnes.
Among this year's extreme weather events were wildfires that scorched Europe and North America, floods that submerged South Asia and hurricanes that swept through the United States and the Caribbean.
