Posting this from Australia, being +50 and having lived through one of the hottest summers I can remember.

Strangely enough today we officially went into Autumn yet that too feels like Summer across most of Australia.

This leads me to believe that in fact the world has seriously under estimated climate change.

For what little it is worth, my last 10+ years of lived experience here in Australia has seen things getting hotter and hotter.

My take on the situation is the IPC have actually got it wrong and there are way more, unidentified positive feedback loops in play, meaning the global climate system is actually showing signs of accelerated warning.

Here in Australia we are now in Autumn and the temperature is +10 above average, making it feel like the middle of Summer.

Time will tell, if in the next few year's we once again manage to break this current Autumn heatwave record. I suspect it will.
