The temperatures detected worldwide in the first four months of 2015 place the year as the warmest since temperatures are recorded, 1880.
This has been made public in the latest report by the United States meteorological agency (NOAA), that the global average temperature has risen 0.80 ° C above the 20th century average. Thus, the document explains that during the January-April period, the global temperature of the earth's surface exceeded the average by 1.48 ° C, while that of the sea surface did so by 0.55 ° C .
As for the month of April, experts indicate that the global average temperature over land and ocean surfaces was the fourth highest in history. Specifically, in April the world average temperature grew 0.74ºC above the average of the 20th century.
Thus, the temperature of the land surface exceeded the average by 1.11 ° C, while the sea surface increased 1.08 ° C.
In the latter case, it is the highest temperature recorded since 1880, above the record set in 1998. NOAA points out that in the case of Spain, an increase of 1.7ºC has been observed above the 1981-2010 average, being the fourth warmest April since records began in 1961, down from 1997, 2011 and 2014.
On the other hand, the average Arctic sea ice degree for April was 310,000 square miles, 5.5 percent below the 1981-2010 average.
This is the second smallest measurement of an April since the records of this data began in 1979.
As for the Antarctic sea ice during April, it was 640,000 square miles, 22.4 percent above the 1981-2010 average, being the maximum extent of sea ice in the history of these records, exceeding the same month of 2014 .
