Hottest Month On Record
Leading on nicely from our last blog where we discussed measures to counteract searing heat in our cities, the United States’ National Oceanic and Atmospheric Administration (NOAA) has confirmed that July 2019 was the hottest month on record. NOAA publishes a monthly global climate report and the July 2019 report can be found here.
The report makes for fascinating reading and shows that the rise in temperatures was widespread and almost completely global, with Australasia showing record temperatures for July as did Europe which endured its 15th consecutive heatwave. Perhaps most concerning was the continuing decrease in sea ice across the Arctic and Antarctic region. In the former, the sea ice measurement was the lowest since satellite records began in 1979, whilst the latter recorded levels that were 4.3% lower than the 1981-2010 average – again, another record breaker.
However, it should be noted that whilst the data leads to an inevitable conclusion that indeed July 2019 was globally the hottest month on record, individual continents varied. For example, Africa as a whole recorded its hottest July on record but South America recorded only its 12th highest, and Asia its 8th. There were also some cooler spots, with Finland and parts of Russia recording temperatures that were 2.7°F below the norm.
But sea temperatures are higher than usual with 2019 records up to July showing a measurement that was 1.37°F higher than the 20th Century average of 61.0°F, with only 2016 proving to be marginally higher.
