Climatologists talk about a process of ‘forcing’ when quantifying the influence of atmospheric carbon on global warming The Earth is naturally warmed by radiation from the sun If you were to try to gather this solar heat over... 12 5 12 5 13 0 13 8 14 4 Glossary 14 7 References and Notes Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 15 1 15 1 15 3 15 6 15 8 16 3 Index 16 5 Chapter 1 The Context and Corollaries A billion could live off the Earth; 6 billion living as we do is far too many, and you run out of planet in no time James... a table-spoon full of water What this means is that a small fraction of radiation from the planet, which would normally propagate back out into space, is not permitted to do so by the enhanced CO2 ‘blanket’, and adds 0.7% to atmospheric and surface warming This undoubtedly seems to be rather insignificant in relative terms, and consequently it is difficult not to ask: ‘What is the problem?’ The answer... Earth’s orbit around the sun changes periodically from circular to elliptical in shape on about a 10 0,000 year cycle At present the orbit is almost circular (eccentricity = 1) but it can have a value in the range 1. 25 1. 3 In this case the Earth can be carried much closer to the sun and it is additionally warmed during these excursions The ice records of CO2 and temperature faithfully echo these planetary .
