The WMO also observed that 1c threshold for rise in global temperature might be crossed anytime soonlooking at the estimates.

Jarraud said that this is a bad news as the 2010-2015 periods have been the hottest in the history so far.
Symbolic milestones are also being reached with this year’s average temperature likely to reach the one full degree above the pre-industrial era.
The researchers stated that an El Nino’s effect is usually felt more firmly in the next calendar year, meaning that 2016 is not unlikely to be more powerfully affected by the occasion than 2015.
El Niño is already thought to have contributed to October 2015 being the warmest on record, at 0.98°C (1.76°F) above the 20th century average for the month.
The data may put an end to the notion touted by sceptics of man-made climate change that warming has been on hold since 1998, another year in which the El Nino phenomenon boosted temperatures.
As world leaders prepare to wrangle over a climate deal in Paris, the World Meteorological Organization (WMO) has announced that 2015 is on track to become the warmest year on record. The UN agency, NOAA, NASA and Japan’s weather agency all say 2014 is the current record hot year with a global temperature of 58.23 degrees.
“Out of the 17 pages, we can exact three main key messages from the report”.
The figures published on Wednesday by the World Meteorological Organisation will provide a grim backdrop to the UN COP21 climate conference which gets underway in Paris next Monday. If carried through, experts say, those cuts could limit global warming to 3 degrees Celsius – 1 degree beyond the limit at which they warn the planet could face catastrophic weather events. Incidentally, this was the target which was agreed upon way back in 2010 in order to prevent any drastic change, causing extreme weather formation. “We have a choice”, said Jarraud. “Future generations will not”, he stressed. The sea level also rose significantly due to melting of glaciers in the year 2015.
Australia last month had its warmest October on record and a heatwave early in the month set new records for early season warmth. “Levels of greenhouse gases in the atmosphere reached new highs”.
2011-2015 will be the warmest five-year period on record, registering a 0.57C increase on the 1961-1990 average, the WMO added.

Dr Ed Hawkins, climate scientist at the National Centre for Atmospheric Science (NCAS), University of Reading, said: “Not only is 2015 going to be the warmest year on record, but analysis by climate scientists shows that the vast majority of this extra heat is as a result of human activity emitting greenhouse gases”.
