The World Meteorological Organization (WMO) has revealed that 2015 may turn out to be the warmest year in recorded history, and the five-year period between 2011 to 2015 being the hottest 5-year period. The WHO blamed the rising global heat and its attendant results on gathering El Nino and human activities – a position that might influence the scheduled climate change conference taking place in Paris this week.

"The state of the global climate in 2015 will make history as for a number of reasons," said WMO Secretary-General Michel Jarraud. "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.

“2015 is likely to be the hottest year on record, with ocean surface temperatures at the highest level since measurements began. It is probable that the 1°C Celsius threshold will be crossed. This is all bad news for the planet," he said.

Jarraud believes that behavioral change and economic turnarounds, greenhouse gas emissions can be controlled and reduced to the barest minimum provided humans and nations have the required knowledge and tools needed to act. Unless decisive action is taken, he added that El Nino continues to gather strength, and even though it made October very warm, this consequence might continue into next year.

The rate of warmth across the world might make this year the hottest on record, and considering the rising temperature in global waters and on land, climatologists are convinced 2015 might win the award for warmest year on land. To this end, South America, Oceania, Asia, Africa and Europe are getting warmer in varying degrees.

In compiling their five-year analytical report as to the rising global temperatures, WMO blamed certain factors for the worldwide phenomenon. These among others include El Nino; rising water levels across seas coupled with carbon-dioxide being absorbed from the atmosphere into the ocean to generate ocean heat; regional temperatures in places such as Eurasia, South America, Africa, western North America, Australia, and China among others; unusual heatwaves across north Africa, Middle East and Europe; drought and rainfall; tropical cyclones; environmental influences from the Arctic and the Antarctic; and climate change attribution among others.
