Fortunately it has. Finally, be suspicious of the doomsayers . Fear and conflict are terribly useful for raising funds, gaining members, mobilising action. They are so useful they are over-resorted to. It is nice to line up people into good altruists and the evil greedies, but life is much more complicated than that.

With global warming, for example, as the Chairman noted, the global temperature was higher a 1000 years ago, the official UN predictions of temperature change are well within the range of past climatic changes in Earth's history, even within human experience. The official predictions of temperature increase are also dropping and are likely to drop further. Given that human action is responsible for a small percentage of total global carbon dioxide emissions, the lack of confirmation is not surprising. So, yes there are environmental pressures and yes these will increase, but if we make the right choices, we will be able to handle these environmental pressures. Endnotes 1 .
