Yesterday NOAA released its monthly global planet report and we are not surprised to find August was the 16th month in a row of record warmth for the globe, the longest such streak in 137 years. If this trend carries on Northern Europe will soon be having Christmas dinner in on the beach. Joking apart NOAA claim August 2016 was 1.66 degrees F above the 20th-century average, breaking last years’ record for the warmest August on record by 0.09 degrees F, The June–August seasonal temperature was 1.6 degrees F above average, surpassing the heat record for this period set in 2015 by 0.07 degrees.  For the year to date, the average global temperature was 1.82 degrees F above average, also breaking the heat record set in 2015 by 0.29 degrees.
These figures may seem miniscule but it is a worrying trend as every month raises the bar a little higher.

More notable findings around the world include from NOAA’s report include:
The globally averaged sea surface temperature was second warmest on record for August and warmest on record for both the season (June–August) and the year to date (January–August).
The globally averaged land surface temperature was record high for August, the season (June–August) and the year to date (January–August).
Record-warm continents: Africa and Asia had their warmest August; South America had its second; North America its sixth; Europe its 10th; and Oceania its 19th.
The average Arctic sea ice extent for August was 23.1 percent below the 1981–2010 average. This was the fourth smallest August extent since records began in 1979.
The average Antarctic sea ice extent for August was 0.2 percent above the 1981–2010 average, the 19th largest on record for the month.
