January and February were also unusually warm, according to scientists
March 2016 was the warmest March on record since at least 1891, making it the 11th consecutive month to set a global temperature.
This statistic is based on data ascertained by meteorological agencies in Japan. NASA, the National Oceanic and Atmospheric Administration (NOAA) and the UK Met Office, will make their calculations soon but their findings may differ slightly from the ones in Japan.
Scientists believe that the record warmth may be caused by the combined efforts of the El Niño event in the tropical Pacific Ocean and the increasingly apparent effects of long-term human-caused global warming.
It is believed, that the El Niño has apparently pushed up the already elevated temperatures to dangerously high levels.
The effects of global warming are already starting to manifest in the form of global coral bleaching, which is harming - and in some cases, killing - reefs from the Great Barrier Reef to the Flordia Keys.
A freak heatwave swept across Greenland this week as part of its melt season, which has commenced one month earlier than expected. Temperatures are soaring into the low 60's Fahrenheit in the south of the country.
The record warmth last month follows on from the usually warm weather which occurred in January and February.
But although the record set in March of this year is noteworthy, scientists say they are more concerned with long-term trends rather than an arbitrarily defined calendar period.
