Seven months of new highs in global temperatures have been reported by NASA. April was 1.11C warmer than the 1951-1980 average. Before October 2015 the difference between the average and a single month had never exceeded 1 degree Celsius.
Since 1985 there has been a string of 369 consecutive months at or warmer than the average. And the last three the record has been broken by the largest margin ever.
But according to the National Oceanic and Atmospheric Administration (NOAA) and, Japanese Meteorological Agency (JMA) datasets, this has the 12th consecutive warmest month. Their data varies only 0.1C form NASA's. They say all continents recorded at least a top 9 warmest April, and for Africa, Asia and South America, it was the warmest on record.
Only some places had cooler than the average conditions, like northeastern Canada which was 5C below average. Cool spots were also recorded in parts of northern Pacific and Atlantic Oceans and southern South America.
Christiana Figueres, former UN Climate talks chief said this "is partly human and man-made, at the moment we have a current record combination of El Niño which is a completely natural phenomenon and the overlay of climate change which is man made."
2016 is expected to be the hottest year on record and, if the trend continues, by the largest margin. Scientists say what's interesting is the scale at which records are being broken, "clearly all heading in the wrong direction."
