World temperatures are on course to rise 6C by the end of the century because of global warming, a major British study has forecast.
What they\’ve actually said is that it might.
Professor Le Quere said the situation could get worse as the world loses the ability to absorb greenhouse gases in natural \”carbon sinks\” like oceans and forests.
The report, published in the journal Nature Geoscience, found that over the past half century the average \”airborne fraction\” of carbon remaining in the atmosphere had probably increased from 40 to 45 per cent because the oceans were less able to absorb the greenhouse gas.
Which brings us back to our old favourite. We really don\’t (this is as in, *we do not know*) what the balance of feedback processes is. Everyone is guessing in a more or less informed manner.
Which rather means that this isn\’t a new report: it\’s just a rehash of one of the more extreme scenarios from the IPCC process.
