A record June for global heat
June a global scorcher as records melt, The Age July 22, 2014 Peter Hannam Environment Editor, The Sydney Morning Herald Last month was a scorcher for global temperatures with warmth over land and sea breaking records for June while sea-surface temperatures posted their largest departure from long-term averages for any month.
Combined average temperatures over land and sea were 0.72 degrees above the 20th century average of 15.5 degrees, making it the hottest June and adding to the record May and equal record April, according to the US National Oceanic and Atmospheric Administration (NOAA).
More striking for climatologists, though, were the sea-surface temperatures. These came in 0.64 degrees above the 20th century average of 16.4 degrees – the first time any month had exceeded the long-run norm by more than 0.6 degrees.
Parts of all major ocean basins notched their warmest June, with almost all the Indian Ocean and regions off south-eastern Australia the hottest on record.
An El Nino event remains about a 70 per cent chance of forming during the northern summer, which could see more records tumble. The weather pattern sees the central and eastern equatorial Pacific Ocean becoming relatively warm compared with western regions, and typically brings hotter, drier than usual conditions to south-east Asia and Australia.
Australia posted its hottest 12 months on record in the year to June, while 2013 was the hottest calendar year in more than a century of records, according to the Bureau of Meteorology.
While June was another month of above-average temperatures, Western Australia and the Northern Territory were cooler than normal – breaking a sequence begun in February in which every state or territory had above-average warmth, NOAA noted.
June was the 352nd month when global temperatures were above the 20th century average – with the last below-average month in February 1985……….
