‘No to wind turbines’ proclaim the stickers on road signs near flooded meadows around Wareham.

Intended as a protest, they become an explanation!

The challenge to science deniers was issued recently and duly answered.

So to address the guesswork might I reassure readers that wind turbines pay back their embedded carbon in three years. One expects a turbine to repay its carbon footprint 20 times.

Carbon dioxide is a concern not as pollution but as a greenhouse gas. If there were no such gases at all the earth would be ice bound to the equator.

The balance is delicate. Increases are very important. The warmed oceans not only melt ice but power winds and increase rainfall.

The false promise of balmy warmer weather conceals a fist of increased storms aggravated by rising sea levels.

The rise in levels is not conjecture or guesswork but a matter of measurement.

In time central Weymouth will become repeatedly vulnerable to flooding.

To suggest ‘business as usual’ is the answer is insanity.

Free markets, selfishness, deregulation and greed have caused the 2008 banking crisis and the impending environmental crisis.

Nicholas Stern, a former World Bank chief economist said: “Climate change is a result of the greatest market failure that the world has seen”.

As Einstein stated “Insanity: doing the same thing over and over again and expecting different results.”

We need to change our economic thinking and embrace a third industrial revolution of green technology – wind, solar, tidal and wave.

To persist in short term narrow profit at the expense of long term survival is the real economic madness.”
