2014 likely to be hottest year on record – WMO

The changes, according to the estimates, are largely due to record high global sea surface temperatures, which are predicted to likely remain above normal until the end of the year.
The report said that high sea temperatures, together with other factors, contributed to exceptionally heavy rainfall and floods in many countries and extreme drought in others.
The high January to October temperatures, according to WMO Secretary General Michel Jerraud, occurred in the absence of a full El Niño-Southern Oscillation (ENSO).
ENSO occurs when warmer than average sea-surface temperatures in the eastern tropical Pacific combine, in a self-reinforcing loop, with atmospheric pressure systems, thus affecting weather patterns globally.
During the year, sea surface temperatures increased nearly to El Niño thresholds but this was not coupled with an atmospheric response. However, many weather and climate patterns normally associated with El Niño/Southern Oscillation were observed in many parts of the world.
“The provisional information for 2014 means that 14 of the 15 warmest years on record have all occurred in the 21st century. There is no standstill in global warming,” said WMO Secretary-General Michel Jarraud,” he said.
He said what was observed this year is consistent with what they expect from a changing climate.
Jarraud explained that record-breaking heat combined with torrential rainfall and floods destroyed livelihoods and ruined lives. He said what is particularly unusual and alarming this year are the high temperatures of vast areas of the ocean surface, including in the northern hemisphere.
Record-high greenhouse gas emissions and associated atmospheric concentrations, according to Jarraud, are committing the planet to a much more uncertain and inhospitable future.
Christiana Figueres, Executive Secretary UN Framework Convention on Climate Change (UNFCCC) commenting on the report expressed fear that the changing climate and risks of extreme weather events will have an increased impact on humanity.
“Fortunately our political climate is changing too with evidence that governments, supported by investors, business and cities are moving towards a meaningful, universal climate agreement in Paris 2015.”
She explained that an agreement that keeps a global temperature rise below 2 degrees C by putting in place the pathways to a deep de-carbonisation of the world’s economy and climate neutrality or ‘net zero’ in the second half of the century is urgently needed.
The reports says if November and December maintain the same tendency, then 2014 will likely be the hottest on record, ahead of 2010, 2005 and 1998.
Western North America, Europe, eastern Eurasia, much of Africa, large areas of South America and southern and western Australia were especially warm.
