To be honest, I’ve been knocked a bit askew by the David Spratt’s question At 4°C of warming, would a billion people survive? The answer according to some respected scientists is, in brief, probably not, something less than a billion, and 4°C seems to be where we are heading.
Where I ended up after a series of happenings as described below, is concluding that we need a paradigm shift in our climate change aspirations. Instead of trying to limit warming to a point where we can avoid dangerous climate change, we need to recognize that we’ve already gone too far, that the climate is already dangerous, so we should aim to ratchet down GHG concentrations in the atmosphere to attain a safe climate.

I pinched that cartoon from the Townsville Bulletin from Facebook, where it was doing the rounds. I think it’s tragic rather than funny, but may go some way to explain why Labor, in Queensland and federally, is over-reacting to the ‘message’ that was sent on Adani, and the prospect of jobs flowing from the resources industry as against climate change and saving the planet. Both Queensland and federal Labor appear to be caving in to coal interests, and both appear to be clueless about the urgency of the climate emergency.

Commonly 2°C has been seen as the threshold for dangerous climate change, although last year the IPCC report on 1.5°C revealed that at that lower level we enter a zone where tipping points may take us to 4°C and beyond.
In 1999 NASA lost its $125-million Mars Climate Orbiter because spacecraft engineers failed to convert from Imperial to metric measurements when exchanging vital data before the craft was launched. Numbers are important!
