We have been brainwashed about carbon dioxide
Some scientists were handsomely paid for decades to vilify this useful gas. Many others, directly or indirectly dependent from governments, supported the official line so as not to harm their careers.
This way, over-endebted governments would be able to launch a (crippling) new tax, the “carbon tax”, while crony-capitalists, which contribute in a big way to election campaign funds left and right, could stuff their bank accounts with huge subsidies for installing thousands of essentially useless wind turbines.
But finally, the truth has come out, confirming what the Carbon Sense Coalition had been saying all along:
Carbon Dioxide Enhances Food Production
Indeed, a new study reveals with scientific precision what climate skeptics knew all along: CO2 is a good guy, not Public Enemy nº1
Here is the new study by Craig D. Idso, Ph.D., Center for the Study of Carbon Dioxide and Global Change – 18 October 2013
The Positive Externalities of Carbon Dioxide:
Estimating the Monetary Benefits of Rising Atmospheric CO2 Concentrations on Global Food Production
“Advancements in technology and scientific expertise that accompanied the Industrial Revolution initiated a great transformation within the global enterprise of agriculture. More efficient machinery and improved plant cultivars, for example, paved the way toward higher crop yields and increased global food production. And with the ever-burgeoning population of the planet, the increase in food production was a welcomed societal benefit. But what remained largely unknown to society at that time, was the birth of an ancillary aid to agriculture that would confer great benefits upon future inhabitants of the globe in the decades and centuries to come. The source of that aid: atmospheric carbon dioxide (CO2).
“Several analyses have been conducted to estimate potential monetary damages of the rising atmospheric CO2 concentration. Few, however, have attempted to investigate its monetary benefits. Chief among such positive externalities is the economic value added to global crop production by several growth-enhancing properties of atmospheric CO2 enrichment.
“As literally thousands of laboratory and field studies have demonstrated, elevated levels of atmospheric CO2 have been conclusively shown to stimulate plant productivity and growth, as well as to foster certain water-conserving and stress-alleviating benefits. For a 300-ppm increase in the air’s CO2 content, for example, herbaceous plant biomass is typically enhanced by 25 to 55%, representing an important positive externality that is absent from today’s state-of-the-art social cost of carbon (SCC) calculations.
“The present study addresses this deficiency by providing a quantitative estimate of the direct monetary benefits conferred by atmospheric CO2 enrichment on both historic and future global crop production. The results indicate that the annual total monetary value of this benefit grew from about $20 billion in 1961 to over $160 billion by 2011, amounting to a total sum of $3.5 trillion over the 50-year period 1961-2011. Projecting the monetary value of this positive externality forward in time reveals it will likely bestow an additional $11.6 trillion on crop production between now and 2050.
“The incorporation of these findings into future SCC studies will help to ensure a more realistic assessment of the total net economic impact of rising atmospheric CO2 concentrations due to both negative and positive externalities. Furthermore, the observationally-deduced benefits of atmospheric CO2 enrichment on crop production should be given premier weighting over the speculative negative externalities that are projected to occur as a result of computer model computations of CO2-induced global warming. Until this is done, little if any weight should be placed on current SCC calculations.”

Then there is this great article by Matt Ridley just published in The Spectator:
Why climate change is good for the world
Here are some excerpts:
”There are many likely effects of climate change: positive and negative, economic and ecological, humanitarian and financial. And if you aggregate them all, the overall effect is positive today — and likely to stay positive until around 2080. That was the conclusion of Professor Richard Tol of Sussex University after he reviewed 14 different studies of the effects of future climate trends.”
”The chief benefits of global warming include: fewer winter deaths; lower energy costs; better agricultural yields; probably fewer droughts; maybe richer biodiversity. It is a little-known fact that winter deaths exceed summer deaths — not just in countries like Britain but also those with very warm summers, including Greece. Both Britain and Greece see mortality rates rise by 18 per cent each winter. Especially cold winters cause a rise in heart failures far greater than the rise in deaths during heatwaves.”
”The increase in average carbon dioxide levels over the past century, from 0.03 per cent to 0.04 per cent of the air, has had a measurable impact on plant growth rates. It is responsible for a startling change in the amount of greenery on the planet. As Dr Ranga Myneni of Boston University has documented, using three decades of satellite data, 31 per cent of the global vegetated area of the planet has become greener and just 3 per cent has become less green. This translates into a 14 per cent increase in productivity of ecosystems and has been observed in all vegetation types.
”Dr Randall Donohue and colleagues of the CSIRO Land and Water department in Australia also analysed satellite data and found greening to be clearly attributable in part to the carbon dioxide fertilisation effect. Greening is especially pronounced in dry areas like the Sahel region of Africa, where satellites show a big increase in green vegetation since the 1970s.
”It is often argued that global warming will hurt the world’s poorest hardest. What is seldom heard is that the decline of famines in the Sahel in recent years is partly due to more rainfall caused by moderate warming and partly due to more carbon dioxide itself: more greenery for goats to eat means more greenery left over for gazelles, so entire ecosystems have benefited.
”Even polar bears are thriving so far, though this is mainly because of the cessation of hunting. None the less, it’s worth noting that the three years with the lowest polar bear cub survival in the western Hudson Bay (1974, 1984 and 1992) were the years when the sea ice was too thick for ringed seals to appear in good numbers in spring. Bears need broken ice.”
”Building wind turbines, growing biofuels and substituting wood for coal in power stations — all policies designed explicitly to fight climate change — have had negligible effects on carbon dioxide emissions. But they have driven people into fuel poverty, made industries uncompetitive, driven up food prices, accelerated the destruction of forests, killed rare birds of prey, and divided communities.
“To name just some of the effects. Mr Goklany estimates that globally nearly 200,000 people are dying every year, because we are turning 5 per cent of the world’s grain crop into motor fuel instead of food: that pushes people into malnutrition and death. In this country [The UK, ed], 65 people a day are dying because they cannot afford to heat their homes properly, according to Christine Liddell of the University of Ulster, yet the government is planning to double the cost of electricity to consumers by 2030.
”As Bjorn Lomborg has pointed out, the European Union will pay £165 billion for its current climate policies each and every year for the next 87 years. Britain’s climate policies — subsidising windmills, wood-burners, anaerobic digesters, electric vehicles and all the rest — is due to cost us £1.8 trillion over the course of this century. In exchange for that Brobdingnagian sum, we hope to lower the air temperature by about 0.005˚C — which will be undetectable by normal thermometers.”
