It’s the sort of anniversary you don’t want to celebrate.

Early reports indicate that April was another record hot month – by some margin – making it 12 months in a row that have set new high marks for heat.

Eric Holthaus, a US-based meteorologist took to Twitter with an estimate that sea and land-surface temperatures would again top 1 degree compared with the average for 1951-80 period used by NASA.

The previous biggest anomaly for April was recorded in 2010 at 0.83 degrees, implying that last month was easily the warmest ever registered for the month.

If confirmed by major meteorological agencies within coming weeks, the April figures would continue the remarkably warm start to 2016, with each month among a handful over the most abnormally hot months in more than 130 years of global figures.

Australia is also exceptionally warm. During the first four months of 2016, average mean temperatures were 1.28 degrees above the 1961-90 period used by the Bureau of Meteorology for its benchmark.

The previous record to this point of the year was 1.16 degrees in 2005, Blair Trewin, senior bureau climatologist, told Fairfax Media……….http://www.smh.com.au/environment/climate-change/april-joins-parade-of-record-global-temperatures-making-it-12-months-in-a-row-20160502-gokkg2.html
