Australia: Heatwave 'connected to climate change' Climate Ark:

"There's a 'high chance' a heatwave sweeping Australia's southern and eastern states is related to climate change, a scientist at the Bureau of Meteorology says. [...] This (the heatwave) is a truly extreme event,' Dr Stern says. 'Many places have established all-time records for the first half of November.' The Meteorologist says the heatwave is caused by the absense of southerly wind flows. 'There is considerable variability in the climate and we do have in the background [that] the globe has warmed up by nearly a degree celcius over the last 50 years, so temperatures are higher now than they were then."
