Steve stopped to chat with friends wherever he turned, we bought provisions, and I bought a few gifts for my family. I was intrigued by the number of people wearing yellow t-shirts with the logo you see at …

Critics of nuclear energy are just as effective, referring to issues such as the large costs of instalation, collateral security risks and problems of disposal of spent uranium.

So it is with fracking, a process that extracts natural gas from reserves that cannot be exploited by conventional drilling methods.

Environmentalists in favour of fracking, such as Lovelock, refer to the world’s continuing need for fossil fuels to generate electricity.  GHG emissions from natural gas are well below emissions from coal and conventional oil.  So fracking, which has greatly increased the supply of natural gas, enables the US to reduce its GHG emissions by phasing out use of coal in the production of electricity.
