That most disturbing thing about your prognosis is that it makes a kind of mundane sense. Man ignores impending disaster because he's busy focussing on self-interest things.

Coming to realise that future events are mostly predictable in a probability wave kind of way - the information is already under our noses - it's just a matter of recognising and weighting it

Your scenario whereby remedial action turns out to be too little too late, which then leads to desperate measures such as climate manipulation technology is a very plausible reading of the tea leaves - presumably countries would be working on this already do you think? Would make a good movie plot even if they're not!

One possible trigger could be a food shortage - there are increasing swathes of agricultural land in Australia that are becoming unsustainable - if that was multiplied across the globe - but then again it may just trigger hoarding and conflict rather than any action.

Meanwhile, the heatwave is set to reload this week. Large parts of inland Victoria and NSW are looking at another run of 4 x 40+ days starting from tomorrow - Friday is shaping up as the dangerous one so far as bushfires go - up to 45C in many places and 40kph winds.
