It was an extreme and unusual event. Climate change is not defined by a "one off" rare extreme events.
Time for serious consideration is if several different events in differnt parts of the globe appear as though they EACH have transgressed from rarity to just a little, just a little more regular.
Many many years ago we had a duststorm in Melbourne CITY. It got dark in the afternoon. It may not have been as big as this but never before seen in Melbourne city.
So what. It came and it went. It was not a precursor or identifier of global climate catastrophy.
