- The average temperature was 14.6 degrees Celsius, more than 0.8 in 1880
- The 12 years of this century are among the 14 warmest of the entire record
The average global temperature in 2012 was the ninth highest since records began in 1880 the data, continuing the upward trend of recent years , said today NASA .
NASA said that with the exception of 1998, nine years with the highest temperatures in this archive file have occurred since 2000, with 2005 and 2010 as the warmest .
The average temperature stood at 14.6 degrees Celsius, 0.8 degrees higher than in 1880, according to new analysis released by the Goddard Institute for Space Studies (GISS), which monitors the temperature of the earth’s surface permanently.
The National Oceanic and Atmospheric Administration (NOAA) also submitted the data analysis that puts 2012 as the tenth warmest year, a disparity that is due to the different methodology used by each agency.
Scientists predict that each decade is warmer than the previous
However, the two agencies agree that the temperature of the planet increases progressively and is expected to even increase in the future due to continued rising levels of greenhouse gases in the Earth’s atmosphere.
“Each successive year will not necessarily be warmer than the previous year, but with the increase in greenhouse gases, scientists expect each successive decade will be warmer than the previous decade, “said NASA.
According to NOAA, the past year also marks the 36th consecutive year with above average temperatures recorded in the twentieth century. Including last year, the 12 years of this century are among the 14 warmest entire recorded period.
The FDA notes that most of the world record higher temperatures average and NASA noted that temperature was a year of “extreme” with a summer with rates above average for that station.
However, the global temperature was offset by relatively cool temperatures in Alaska, Canada and parts of Asia and the phenomenon of “La Niña”, a phenomenon that leads to the cooling of the sea.
Moreover, the Arctic experienced a record melt season while extending the Antarctic sea ice was above average for most of 2012.
