Recent geological, biological, and astronomical discoveries are bringing us closer to understanding whether we might be alone in the Universe. The current consensus is that Earth- like planets have reasonably stable climates and that the forces of natural selection are sufficiently powerful to allow life to adapt to any fluctuations. This book questions that conventional wisdom and suggests, instead, that the Earth may have had 'four billion years of good weather' purely by chance.
If Earth-like worlds don't have natural stabilising mechanisms, then intelligent observers such as ourselves will only ever look out onto those rare planets where, like the Earth, all the bad things that could have happened to the climate have fortunately cancelled each other out.
So before you prepare to meet the aliens, consider that we are probably alone .
