Guest essay by Eric Worrall

“Settled” Climate Science apparently needs a lot more hands on deck to help explain to us how doomed we are if we don’t spend taxpayer’s money on climate stuff.

More climate scientists urgently needed for Australia, academy says Peter Hannam Australia’s climate research is in “urgent” need of dozens more scientists to help prepare farmers, businesses and governments for the expected worsening effects of global warming, the Australian Academy of Science said. The academy’s assessment, prompted by last year’s decision by CSIRO to axe as many as 100 of 140 climate scientists, identified 77 extra research positions that should be created in the next four years. … “Climate change is affecting and will affect every business and every bit of the environment in Australia,” said Trevor McDougall, an academy fellow and professor at the University of NSW, who led the review. Professor McDougall cited uncertainty over how a warming climate will alter rainfall and evaporation in the Murray Darling Basin, the country’s biggest food bowl. Only Australians would prioritise such a topic, he said: “That’s an issue models in the northern hemisphere won’t even look at.” …

Interesting that “Northern” models aren’t expected to bother with climate change in the Southern hemisphere.

The earth’s climate is subject to hard thermodynamic constraints. Energy which powers extreme weather in one part of the world has to be deducted from the energy budget of other parts of the world, to make the sums balance. Global warming does not increase the power available to drive the heat engine which is the Earth’s climate – the power available to drive the Earth’s climate is pretty much fixed by the rate of energy delivered by incoming sunlight.

Ignoring an entire hemisphere would likely make it difficult to determine whether your apocalyptic regional model projections were violating global climatic thermodynamic constraints.
