… the long-term threat to life on Earth is the exponentially increasing output of heat from the Sun. This is simply the logic of any planet illuminated by a main sequence star. The consequences of solar overheating are already upon us and, but for the regulatory capacity of Gaia, our planet would be moving unstoppably to a state like that of Venus now. What saves us is the continuous and sufficient pump-down of carbon dioxide from the atmosphere by land and ocean vegetation.
