Studies: Year 2014 was the hottest in Earth’s recorded history

By  | 

Year 2014 is the hottest so far in Earth’s recorded history, two separate studies conducted by scientists over at NASA and National Oceanic and Atmospheric Administration (NOAA) have concluded.

The research notes that since 1880, Earth’s average surface temperature has been warming up by about 1.4 degrees Fahrenheit (0.8 degrees Celsius). This trend is a direct result of increase in carbon dioxide and gaseous emissions because of human activities. The research also notes that most of the warming up of our planet has happened over the course of last three decades.

“This is the latest in a series of warm years, in a series of warm decades. While the ranking of individual years can be affected by chaotic weather patterns, the long-term trends are attributable to drivers of climate change that right now are dominated by human emissions of greenhouse gases,” said NASA’s Goddard Institute of Space Studies (GISS) Director Gavin Schmidt.

The research also found that the 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000.

Schmidt added that the data gathered during the study shows that the greenhouse gases are responsible for the majority of the Earth warming trends and with emissions continuing to increase, we will see further increase in temperatures over the course of next few years.

NASA’s GISS analysis incorporates data including surface temperature measurements from 6,300 weather stations, ship- and buoy-based observations of sea surface temperatures, and temperature measurements from Antarctic research stations.

The data is analysed by employing an algorithm that takes into account the varied spacing of temperature stations around the globe and urban heating effects that could skew the calculation. The result is an estimate of the global average temperature difference from a baseline period of 1951 to 1980 reveals NASA.

Studies carried out by UN have also shown similar trends and with increased temperature and rainfall, there will be disruptions in food and water supply globally. The study also found that sea levels are increasing to an extent that will threaten lives of millions of people living near coasts.
