PRETORIA - The United Nations Weather Bureau says the global average surface temperature this year is likely to be the warmest on record.

It says the past five years have been the hottest half decade in recorded history.

The World Meteorological Organisation says the planet's likely to reach the symbolic and significant milestone of 1°C above the pre-industrial era.

This is due to a combination of a strong El Niño and human-induced global warming.

The years 2011-2015 have been the warmest five-year period on record.

Many extreme weather events, especially heatwaves, have been influenced by climate change.

World Meteorological Organisation Secretary-General Michel Jarraud says levels of greenhouse gases in the atmosphere reached new highs and in the Northern hemisphere spring 2015 the three-month global average concentration of CO2 crossed the 400 parts per million barrier for the first time.
