Revkin's Dot Earth Blog: Scientist: Warming Could Cut Population to 1 Billion - Comments from Richard Courtney | Climate Realists

OK. So, Schellnhuber is said to have asserted that if emissions of greenhouse gases - notably carbon dioxide (CO2) - were to rise by 7 deg.F then 5 billion people could die.

But constraining carbon dioxide emissions at their present level would deliberately kill at least 2 billion people - mostly children – before the middle of this century. And reducing the emissions would kill more millions – possibly billions – of people. This would be a genocide of a magnitude not previously possible in all human history.

The reason for this is simple. All human activity is enabled by energy supply and limited by material science, and the human population is growing.

The energy supply enables the growing of crops, the manufacture of tools, and the use of those tools for construction and the provision of goods and services. Material science limits what can be done with the available energy; e,g. an iron plough share is better than a wooden one, ability to etch silicon enables adequately reliable computers, etc.

ECO-BLOAT: EXTRA MELTING OF GREENLAND'S ICE

An email from Dave English [prospector@znet.com] pointing out that the Warmists have not done the math behind their scare

David Adam writes from Copenhagen: "Scientists at the Copenhagen conference said that modest IPCC estimates of likely sea level rise this century need to be increased. Extra melting in Greenland could drive sea levels to more than a metre higher than today by 2100"

This is typical eco-bloat. Taking into account that the Earth's surface is 70% ocean and that it takes 1.1 cubic mile of ice to make a cubic mile of water, to raise the oceans one inch would take 2400 (2398+) cubic miles of ice. To raise the oceans one meter would take 94,488 cubic miles of ice melting. Greenland is melting at 55 cubic miles a year, their dream is to make us believe that the melting would become not two or four times faster than today but 18.67 times faster, from 55 cubic miles a year to 1027 cubic miles a year for 92 years.
