Sydney’s warm week raised its Mean Daily Temperature running average – only by 0.3ºC but nonetheless confounding the 9-month trendline.
Northern England turned chilly, though not as much as Koltsovo, Shanghai and Buenos Aires. Without Sydney’s contribution of warmth, the southern hemisphere would have equalled the north’s cooling. The globe, as represented by the Ten Stations, saw its running average drop 0.3ºC in Week 40. If Sydney returns to its cooling trend and falls to a yearly average of 1.19º above (my) Pre-Industrial baseline at the end of November, that will still represent a 0.34ºC rise above the Ten Year (2009 to 2018) average.
The monster hurricane caused terrible devastation in the Bahamas and, if Puerto Rico’s experience is anything to go by, the people in the worst affected islands will wait a long time for the assistance they need to rebuild communities.
Questions are being asked about the odd behaviour of the storm. Georgia and the Carolinas received a battering – but it could have been worse. And maybe it need not have been as bad as it was for Bahamians.
Dorian is over the Gulf of St Lawrence as I write, and the west coast of Ireland and the Scottish Isles may feel his breath on Tuesday when computer models are showing the storm centre tracking over Iceland.
