Scientist from NASA and the National Oceanic and Atmospheric Administration (NOAA) officially announced on Friday that 2014 is the hottest year ever recorded since 2010.

According to the report released, last year’s global temperatures had been the warmest since 1880. During 2014, the average temperature across global lands and ocean surfaces was 1.24 degrees Fahrenheit (0.69 degrees Celsius) above the 20th century averages.

It is believed that the rising temperatures are a long-term trend factored by the burning of coal, oil and gas, and the changing in the climate. The majority of the increase in temperature has occurred in the past three decades.

2014 may have been the hottest year on record, but the United States didn’t hit record temperatures last year. Some states in the East Coast and Midwest recorded unusually cool temperatures according to the NOAA.
