Yet more climate nonsense to spoil my day. It won’t be sufficient to halt dangerous climate change “merely” to reduce CO2 emissions to zero, according to a report on ABC’s AM programme this morning. We need to go further (beyond zero, if you will excuse the pun), and start sucking CO2 out of the atmosphere (no, really):
MIKE RAUPACH: There is very little wiggle room left, perhaps none at this stage and the issue of course is that a large fraction of the CO2 that goes into the atmosphere stays there for a very long time and that means that what we do now has a long-term future shadow.
SIMON LAUDER: Dr Raupach is part of an international team which used mathematical models to see what will happen to the climate in the long term under various scenarios. He says if emissions aren’t rapidly reduced to zero, future efforts will have to go further and remove CO2 from the atmosphere to prevent warming of more than two degrees.
MIKE RAUPACH: If we do reduce emissions rapidly then zero emissions will do but even a small leakage in the long term like over a hundred years from now, of about 10 per cent of current emissions, is enough to keep temperatures slowly rising. (source)
“Zero emissions will do”!! Phew, that’s OK then. For as we all know, reducing emissions to zero is the easy bit. You only have to look at global energy consumption to see that we’re really, really close to a fully renewable energy budget (the renewables component of the chart is that wafer thin segment on the right, just in case you can’t quite see it):
So once we’ve done that, and we’re all living in the cold and the dark, with no cars, buses, planes and electricity, we can then use whatever energy is left over (which won’t be much) to power synthetic trees (like those pictured above) to remove the CO2 out of the atmosphere. It will be an environmentalist’s dream – a landscape littered with useless windmills and fake trees, with no humanity and no prosperity. Just what Bob Brown wants for Australia. And the climate will continue to do exactly what the hell it wants, because that’s what the climate does.
And Lauder gets full marks for conducting, to the letter, the standard ABC interview of a climate alarmist, where the alarmist is allowed to talk as much nonsense as he/she likes completely unchallenged, and without having to account for any of the ridiculous assertions he/she makes. At no point does Lauder challenge the scientific basis of the UN’s 2 degree target, or the reliability of the “mathematical models” of which he is obviously so in awe, or whether adaptation strategies might provide better value for money than mitigation, or whether the release of this story is simply clever timing a few days before yet another pointless climate gab-fest in Durban.
But that would be asking too much of the “groupthink-infested” ABC, wouldn’t it?
