In relation to letters by M Kuipers von Lande and M Houlding (The Sun, November 29), global warming is not a god created by the Greens, it is a reality owned by the world. The prospect of humans affecting global climate first emerged in the 19th Century, long before Green politics appeared.

The possibility of catastrophic global temperature decrease (nuclear winter) was discussed during the 1970s, based on known short-term effects of volcanic eruptions. Predictions about global warming emerged in the 1980s, supported and confirmed by many studies since. The research is based on evidence, not political agendas or belief. I would be delighted if the conclusions prove to be wrong.

The Greens promote sustainable systems for generating energy. It is recognised some technologies are expensive and involve visual pollution, or other environmental effects (such as damming wild rivers).

Best, is direct production of electricity from the sun, because much of the required infrastructure (buildings) already exists.

Income inequality is a serious issue in our society. However, nobody proposes to strip wealth from anybody, or to dismantle capitalism. Redistribution of wealth will involve restructuring the tax system, among other things, and will take time. Examples exist in several Scandinavian countries, where measures of human happiness are among the highest in the world. Eddie Orsulich is not a Green Party spokesperson, although he defends the Green perspective.

The Denniston Plateau is one of our few remaining pristine wildernesses and is deserving of protection for that reason alone.
