Twin omega blocks to cause severe weather in Australia
A unique weather pattern involving two omega blocks, a tropical cyclone and a heatwave will cause a dynamic mix of severe weather in Australia from this weekend into next week.
"The shocking visual is prompting many to ask whether this recent surge [in #ocean heat] is evidence that human-caused heating has propelled the #climate past a #TippingPoint.
Climate scientists say the answer is likely no. Instead, it is much more probable to be ... a coincidence of natural factors piled on top of the steady trend of human-caused global heating. "
"At the same time, in the high latitudes of Canada and the far North Atlantic, a very blocked #JetStream pattern has persisted for weeks. These persistent weather patterns have a significant impact on the underlying sea surface temperatures."
This #OmegaBlock has a hand in the wildfires in Canada, warmed up the northeast Atlantic, and has resulted in "record-shattering heat" in the tropical Atlantic.
