Human activities to blame for unprecedented climate changes and global warming

Geneva: A report by United Nation's World Meteorological Organization (WMO) says that 2015 was the hottest year since 2000 and the researchers are blaming the greenhouse gases and the man-made activities for the fuelling heat waves and downpours.

About fifteen of the 16 hottest years on record belonged to this century, the exceptionally strong El Nino and the greenhouse gases together had the effect on the climate system in 2015. The influence of El Nino will weaken in the upcoming time, but the effect of human-induced climate change will be there with the people for several decades.

The researchers are trying to explain the factors, including the heat from one warm year into another and the temperatures are identical in many years making it difficult to rank the temperatures. The change in the climate will have more and more damaging impacts for at least upcoming five decades that is highlighting the need to invest in adaptation along with mitigation.

The U.N.'s WMO report has confirmed the data gathered by U.S. and British that also has the statement showing that 2015 was by far the warmest year on record. Last month the nations collectively agreed in Paris to plan the measures in order to protect the Earth in the future.
