2016 may be the hottest year in history

Many meteorological agencies around the world warn that 2016 will continue to break the record and become the hottest year in history.

According to Scientific American, the US Aeronautics and Space Administration (NASA) and the US National Oceanic and Atmospheric Administration (NOAA) rated last April the hottest April in history, and the 12th month. successively set a record for the highest monthly temperature, due to the resonance of climate change with the El Nino phenomenon.

Global temperatures are about 1.5 ° C higher than the pre-industrial average. Specifically, April 2016 average temperature is 1.1 ° C higher than April average temperature in the 20th century (13.7 ° C) and 0.3 ° C higher than the annual record. 2010.

The nonprofit Climate Central, USA, re-analyzed NASA and NOAA's average temperature data for the first months of this year, and compared them to the average of 1881-1910. The average temperature from January to April is 1.45 ° C higher than the period 1881 - 1910.

In 2015, at the COP21 Global Conference on Climate Change held in Paris, France, national governments pledged to keep the temperature of the Earth from rising by more than 2 ° C by the end of the century, compared to the period Industrial money. The current global average temperature is about 15 ° C.

"The average monthly temperature is surpassing the record thresholds for previous temperatures , and this will happen more often," said Michael Mann, climate expert at the University of Pennsylvania, USA.

Countries are trying to cut carbon dioxide (CO ₂ ) emissions and many other greenhouse gases to accomplish that goal. According to NOAA, the global average CO ₂ concentration reached a record level, exceeding 400 million parts (ppm) in March 2015. The average growth rate of atmospheric CO ₂ concentration in the period of 2012 - 2014 is 2.25 ppm / year.

"This is a milestone that shows that people burn fossil fuels, causing global CO2 concentrations to rise to 120ppm from pre-industrial times," Earth Sky quoted Pieter Tans, a greenhouse gas expert at NOAA.

The El Nino phenomenon is showing signs of weakening, causing the average monthly temperature to gradually decrease, but the temperature is still significantly higher than in 2015.

According to Gavin Schmidt, head of NASA's Goddard Space Research Institute, with temperatures in the first months of 2016, there is 99% of the possibility that this year's average temperature will be higher than last year and become the hottest year in the calendar. history.
