Most people living in the US remember the bitter winter and chilly winds that were endured during 2014. Therefore, it is almost impossible to believe that it could have been the hottest year to date. However, this conclusion come from data provided by the Japan Meteorological Association, which is one of the biggest organization to analyze global temperature, apart from NASA and the NOAA in the U.S., and the U.K.’s Hadley Center.
This data is calculated starting from the year 1891, and to put it in more specific numbers, the year 2014 exceeded the time period between 1981 and 2010 by .50 degrees Fahrenheit. In fact, the data also shows that four out of the five hottest years recorded have happened in the last 10 years. The year 1998 is recorded as the second hottest year, while 2010 and 2013 are third, and 2005 is the fifth. So what does this mean for long run averages? These numbers reveal the planet has been actually warming up at an average rate of 1.26 degrees Fahrenheit per century. At least, since the data has begun being collected.
As for this data, confirmation from NOAA and NASA, our U.S. government agencies, is still pending.
