Universe 30 Times More Run Down Than Thought Jan 27, 2010
"The universe started out in a low entropy state and, in accordance with the second law of thermodynamics, the entropy has been increasing ever since," Mr Egan said. "This is important because the amount of energy available to life in the universe, including terrestrial life, depends on the entropy of the universe. We'd like to know how much energy will be available to life forms anywhere in the universe, and where this energy is. The first step in this procedure is to determine the entropy of...

What Keeps Time Moving Forward? Blame It on the Big Bang Jan 10, 2010
Entropy, which in rough terms is the measure of a system's disorder, creeps up over time, as dictated by the second law of thermodynamics. To illustrate entropy's inexorable growth, Carroll takes us to the breakfast table you can't unscramble an egg, he points out, and you can't unstir the milk out of your coffee. (Scientific American)
Science: No hiding place? Jan 10, 2010
Nevertheless, while there is a lot of scepticism in, around and about climate science, none of it is aimed at the first law of thermodynamics, which says that energy cannot be created or destroyed. The energy that the sun delivers to the Earth must therefore be equal to the energy that is reflected back into space, plus that re-emitted as infra-red radiation, plus that stored in some part of the atmosphere, the oceans or the land.
