CO2 IS A BENEFIT, SO LET US GIVE THANKS

The Scotsman, 16 March 2016

DON’T believe computer prophets of doom, writes Dr Keith P Dawson, vice President at the Scottish Society of Crop Research

Last month’s major scientific breakthrough was rightly lauded; Einstein’s century-old gravitational wave theories proved correct. How will we view current theoretical climate science in 2100? Will there be global headlines confirming validity or a consigning to history’s dustbin?

So far prospects are worrying, with climate computer predictions, on which costly taxpayer-funded policies are based, well wide of measured reality. In terms of temperature increase, ocean acidification, sea levels and polar ice, predictions have massively exaggerated what is happening. Polar ice and bear populations are now larger than when Al Gore made doomsday predictions ten years ago. This is the year Arctic ice vanishes completely, remember?

The “burning” question is the real extent to which CO2 influences global temperature. There was cynical “rebranding” of global warming as “new improved” climate change; when it became clear measured data showed no significant global warming since 1998 and still doesn’t. This despite models predicting large increases and CO2 increasing over the period, so why trust future predictions; up or down? The sensitivity of models to CO2 is now challenged, they may “run hot” by up to 300 per cent, models ignore clouds, key climate factors.

There’s a big difference between climate and weather – despite perceptions global extreme weather damage is actually decreasing, as are climate-related deaths, according to the UN. El Nino was by far the most important 2015 factor, as in the warmer 1999 and 2011. Media sadly ignore the positive narrative.

So CO2: Hero or Villain? A pollutant according to the US EPA or celebrated as Patrick Moore, GreenPeace founder, suggests? Without CO2 Life on Earth dies. Without CO2, no green plants, no grazing animals, food chain or humans, no wonderful nature documentaries!

Parents with sick children rely on thermometers rather than computer models falsely running Hot. Despite the claims of data-manipulating activist-researchers and politicians, the science is not “settled”. By its very nature, science is never “settled” – the only people who claim that are non-scientists or charlatans or both.
Scottish Government policies based on these models cost Scottish households significant and increasing sums. They drive the poor into food and fuel poverty and divert funds from healthcare, education and research, damaging industry through uncompetitive energy costs.

Since colleagues and I published pioneering research on greenhouse emissions in the early Eighties, the search for scientific truth has too often been hijacked by quests for funding and profile on the multi-trillion dollar climate gravy train. Let’s be clear: there is no such animal as a “Climate Change Denier” – who could deny impacts of climate change over millennia? Vikings cultivated Greenland, Romans tended Yorkshire grapes, even our glens testify to change – the only constant. Only flat-earthers deny change. The “denier” myth is a cynical activist construct to marginalise genuine questioning of the science, which should be welcomed. […]

Recent film The Big Short tells the true story of cynical herd behaviour by banks in the sub-prime market, causing the 2008 global economic collapse. Current climate science and politics has many of the hallmarks of the sub prime disaster. Once again, the gamble is taken with our money and hits the poorest hardest. Public faith in science will, tragically, be part of the collateral damage when the Emperor’s state of undress finally becomes evident. In a democracy people are entitled to their own opinions – but not to their own facts.
