2016 is now the hottest year on record with the temperature 0.07 degrees Celsius higher than 2015, according to NASA, NOAA, and WMO.
Besides the thinning of the ozone layer and deprived green environment, scientists believe that human emission of carbon dioxide also played the major role in global warming. The first six months of 2016 broke the record for having the highest temperature since satellite data recording began in 1979, NASA scientists revealed.
According to the National Oceanic Atmospheric Organization's (NOAA) global annual analysis in 2016 based on anomaly rates covering the years 1880 until 2016, the top seven warmest years are; 2016 with 1.69°F (0.94°C), 2015 with 1.62°F (0.90°C), 2014 with 1.33°F (0.74°C), 2010 with 1.26°F (0.70°C), 2013 with 1.21°F (0.67°C), 2005 with 1.19°F (0.66°C) and 2009 with 1.15°F (0.64°C).
The 10th warmest years in rank got a tie. Years 2003, 2006, and 2007 had the temperature of 1.10°F or 0.61°C.
Climate change results in unpredictable weather conditions and constant changes of global surface temperature levels. El Niño and La Niña phenomenon also contributed to the changing temperature of the Pacific Ocean and the Central Pacific regions.
The National Aeronautics Space Administration (NASA), National Oceanic Atmospheric Administration (NOAA), and the World Meteorological Organization (WMO) recorded 2016 as the hottest year, considering the global surface temperature.
According to India Meteorological Department (IMD), 2016 had the highest temperature level among the top five hottest years since 1901.
NASA recorded a temperature of 1.8°F in 2016, a little different from NOAA.The different data given by different weather and climate monitoring organizations is like singing the same song but with different notes in some parts, according to Deke Arndt, chief of the monitoring branch of the National Centers for Environmental Information.
2017 is expected to have a cooler temperature compared to 2016. El Niño is likely to disappear while La Niña weakens in the coming months.
