In scientific circles, CO2 is referred to as a ‘trace gas’ that, for hundreds of thousands of years, has remained at or below five ten-thousandths of the atmosphere by volume. Even among the so-called ‘greenhouse gases’ (GHG), CO2 accounts for less that 4%, with water vapour being by far the most significant GHG. CO2 is clearly a minuscule component of the massive mechanisms that create climate and cause climate change. . .(via Conservative Grapevine)
At 385 parts per million (ppm) by volume, CO2 levels are now, in a geologic sense, at their lowest in 600 million years. For example, during the exceptionally cold Ordovician glaciation, about 440 million years ago, CO2 levels were more than ten times higher than today. At other times, warm temperatures occurred when CO2 levels were high. During this period, there was no consistent correlation between temperature and CO2 levels. When, in more recent millennia, a correlation appears evident, temperature changes before CO2. Aside from forecasts of still primitive computer models, modern climatological research consistently shows that there is no scientific justification for the CO2/climate hysteria that has so gripped mass media and politicians.
Attempts to maintain the focus against CO2, a colourless, odourless benign gas essential for plant photosynthesis, have become truly ludicrous. Incredibly, CO2 is branded by many as a ‘pollutant’ – the continual references of Al Gore and Senator Barbara Boxer to “global warming pollution” are prime examples. . .
Nigel Calder, former Editor of New Scientist magazine, refers to much of today’s global warming, anti-CO2 movement as “Medieval environmentalism”. Such alarmists, Calder explains in the film The Great Global Warming Swindle, embrace climate change dogma, saying to themselves, “Let’s get back to the way things were in Medieval times and get rid of all these dreadful cars and machines.” Calder says that for extremists, CO2 is “an emblem of industrialization”, something they oppose with a passion.
