With the intensification of the greenhouse effect in recent years, the global temperature has been a breakthrough in the record since the limit, this year is no exception.
(NASA) and the United States National Oceanic and Atmospheric Administration (NOAA) climate experts held a media conference call to publish the 2016 global temperature data, as well as the discussion of 2016 The most important climate change trends.
According to an independent analysis by NASA and NOAA scientists, 2016 is the hottest year since records were recorded and the global mean surface temperature was record-breaking for three consecutive years.
NASA scientists at the Goddard Institute for Space Studies (GISS) analyzed measurements from 6300 locations and found that since the late 19th century, Earth's average surface temperature has increased by about 2.0 degrees Fahrenheit (1.1 degrees Celsius) The degree is due to human activities, emissions of carbon dioxide and other greenhouse gases in the atmosphere.
Most of the warming occurred in the past 35 years, with 17 of the hottest recorded, 16 of which occurred after 2001. 2016 is not only the hottest year since the record, 12 months in 8 months, is the highest temperature over the same month, occurred in January to September, with the exception of June. 2016 October, November and December, the three months of the same period is the second hot month, the temperature below 2015.
The temperature anomalies from 1880 to the present are plotted against the annual average temperature of 1880 to 2015. The warm year is recorded on the right. (Errata: cartographic editing will be the upper left corner of the 1880 written in 1980)
The researchers estimate that the direct impact of El Niño on the tropical Pacific increased the global temperature anomaly by 0.2 degrees Fahrenheit (0.12 degrees Celsius) in 2016.
Weather dynamics usually affect the temperature of the area, so in the past 2016, not every region of the planet has experienced a record average temperature. NASA and NOAA also found that the average annual temperature in the 48 states of the United States is the second highest recorded since the Arctic Circle experienced the hottest year, with most of the year Time to find the low sea ice coverage area consistent.
