The United Nations World Meteorological Organization (WMO) said 2015 was the hottest year since 2000 and it’s all because of greenhouse gases as well the man-made activities.
Last year, the temperatures were 0.76 degrees Celsius above the 1961-1990 average that serves as an internationally agreed base period for evaluating the long-term changes in the climate.
The global temperature through the baseline period was 14 degrees Celsius. The observed runs of record temperatures are extremely questionable to be followed in the absence of human-caused global warming.
The report says, about fifteen of the 16 hottest years on record were all this century. And the exceptionally strong El Nino and the greenhouse gases must have worked together for the effect on the climate system in 2015. The effect of human-induced climate change will be there with the people for several decades, even as the influence of El Nino will fade in the upcoming time.
The researchers are trying to account for the factors, including the heat from one warm year into another, the temperatures are some identical in many years, turning it hard to rank their heat with confidence. The change in the climate will progressively have damaging impacts, including the risk of the disasters, for at least upcoming five decades. This calls for emphasis on the need to invest in adaptation alongside with mitigation.
The U.N.’s WMO report has confirmed the data collected by U.S. and British that also has the statement showing that 2015 was by far the hottest year on record. Last month the nations gathered in Paris in order to plan the measures in order to protect the Earth in the upcoming time.
