2014 will be hottest year

"The year 2014 is on track to be one of the hottest, if not the hottest, on record," the World Meteorological Organisation (WMO) reported on the sidelines of the UN climate talks in Lima.

Provisional data for 2014 shows that 14 out of the 15 warmest years on record have all occurred in the 21st century, it added.

"There is no standstill in global warming," WMO chief Michel Jarraud said in a press statement.

"What we saw in 2014 is consistent with what we expect from a changing climate. 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."

The global average air temperature over land and sea surface for January to October was about 0.57 degrees Celsius (1.03 degrees Fahrenheit) above the average of 14 Celsius

for a reference period from 1961-1990, the WMO said.

It was 0.09 Celsius above the average for the decade 2004-2013.

"If November and December maintain the same tendency, then 2014 will likely be the hottest on record, ahead of 2010, 2005 and 1998," the WMO said.

"This confirms the underlying long-term warming trend."
