HERE we go again, another rant from one of those ‘green merchants of doom,’ "Fracking is lunacy” June 22.

K Hayes claims that the consumption of fossil fuels is directly causing climate change. I don’t think so, as there is no empirical, scientific evidence to prove that the tiny amount of C02 humans release into the atmosphere is causing the climate to change, fact.

No amount of carbon taxes, ‘green levies,’ carbon trading scams, windmills or solar farms will prevent the climate from doing what it has always been doing — changing.

Milutin Milankovitch a Serbian astrophysicist and geophysicist explained the long term changes in the earth's climate caused by the position of the earth in relation to the sun now known as the Milankovitch cycles. This explained the ice ages in the geological past as well as climate changes on the earth which can be expected in the future

Scientists are now beginning to understand the sun’s influence on our climate with regards to its effect on the amount of cosmic rays that enter the atmosphere which in turn may have an effect on the formation of clouds and therefore will have a direct impact on the climate.

Records show that the climate was much different in the recent historical past with warm and cold periods stretching hundreds of years — the medieval warm period, from about 850AD to around 1350AD where temperatures were somewhat warmer than today. We know because during this time the Vikings colonised and farmed on Greenland and the polar bears did not drown. And then the “little ice age” 1400 to 1850 where temperatures were considerably cooler than they are now.

After the invention of the telescope in around 1608 observations made of the sun correlated to a particular cold spell which lasted from about 1645 continuing to approximately 1715 which corresponded with an observed period of hardly any sunspot activity whatsoever, the so called Maunder Minima. During this time ice fairs were regularly held on the River Thames.

I have yet to see any empirical, peer reviewed scientific evidence to unambiguously prove that human activities are causing climate change. All I see and hear are hysterical outbursts from the green movement and sinister, untruthful reports brought to us by a biased media of so called scientific evidence of global warming caused by humans, which is promulgated by those with vested interests to protect, be it financial, political or ideological
