Previously, scientists at NOAA, NASA, and Japan’s weather agency have said that 2014 was the hottest year on record, with a global temperature of 14.57 degrees Celsius (58.23 degrees Fahrenheit).

Climate change made 2011-2015 the warmest five-year period on record, according to the World Meteorological Organisation’s (WMO) state of the global climate report.
Global average surface temperatures in 2015 were likely to reach what the agency called the symbolic and significant milestone of 1C above the pre-industrial era. “It is probable that the 1 degree Celsius threshold will be crossed”, Mr Jarraud said.
This year’s record is down to a combination of rising greenhouse gases and a boost from the strong El Niño underway in the Pacific, says the WMO.
The WMO said the waters have been absorbing more than 90% of the energy that has accumulated in the climate system from human emissions of greenhouse gases.
“Out of the 17 pages, we can exact three main key messages from the report. We have a choice”, said Jarraud.
The news 2015 the warmest year till now: WMO report is important in Current Affairs in Environment and Ecology Affairs.
The data may put an end to the notion touted by sceptics of man-made climate change that warming has been on hold since 1998, another year in which the El Nino phenomenon boosted temperatures.
The WMO said earlier this month that concentrations of the three main greenhouse gases, carbon dioxide, methane and nitrous oxide, all rose to records in the atmosphere in 2014.
The analysis is based on data collected from the month of January 2015 to October 2015 during which an anomaly of 0.73c was observed against the average temperature of 14c for the period 1961-1990. Delegates from almost 200 countries are supposed to finalize the details of a universal climate agreement with the aim of keeping future global temperature increase to below 2 degrees Celsius of the pre-industrial average.
This year is destined for the history books with 2015 likely to be the warmest on record. “This is all bad news for the planet”, he added in a statement. A WMO source said that among the 10 warmest years registered since 1998, 8 among them have been after 2005. Previous year also marked Earth’s hottest on record. Africa and Europe are having their second hottest. It is still starting and it will pick up next year so what we can expect roughly is that next year maybe will be warmer than this year because of the effect of El Nino.
He adds how extreme weather events will now become more prevalent like heatwaves.

And it says that the period 2011-2015 has also broken records, with many extreme weather events, including heatwaves, influenced by global warming.
