The last four years were the hottest since global temperature records began, the UN confirmed on Wednesday in an analysis that it said was a clear sign of continuing long-term climate change. The UN's World Meteorological Organization (WMO) said in November that 2018 was set to be the fourth warmest year in recorded history, stressing the urgent need for action to rein in runaway planetary warming.
There's a 70% chance of a recurrence of the El Niño weather event before the end of this year, according to the World Meteorological Organization.

According to the World Meteorological Organization preliminary statement on the global climate for 2016, global temperatures for January to September were 0.88°C above the long-term (1961-90) average, 0.11°C above the record set last year, and about 1.2°C above pre-industrial levels.

The year 2013 was among the top ten warmest years since modern records began in 1850, according to the World Meteorological Organization (WMO). It tied with 2007 as the sixth warmest year, with a global land and ocean surface temperature that was 0.50°C (0.90°F) above the 1961–1990 average and 0.03°C (0.05°F) higher than the most recent 2001–2010 decadal average.
This year is the seventh warmest since records began in 1850 with a trend to weather extremes and the impact of storms such as Typhoon Haiyan in the Philippines aggravated by rising sea levels, the World Meteorological Organization (WMO) said.
