Svante Arrhenius (1859-1927) was a Swedish scientist who first claimed that the burning of hydro-carbons like coal, oil, gas, peat and wood may cause global warming. In 1895 he calculated (incorrectly) that a doubling of the atmospheric CO2 concentration would lead to a 4-5o C rise in global temperature. However, Arrhenius suggested that this increase could be beneficial, making the various climates on Earth “more equable" and stimulating plant growth and food production. Then a showman/politician, Al Gore, gave life to the theory that extra carbon dioxide due to human activities will cause dangerous global warming. But temperatures refused to obey the alarmist computer model forecasts. So they switched to the universal bogey-man - climate-change, where every bit of bad weather was blamed on western industry. But this did not scare enough people so it morphed into climate emergency, which allows coal, oil, gas, cars and cattle to be blamed for everything bad - floods and droughts, snowstorms and heatwaves, bushfires, coral bleaching, species extinction and pollution anywhere. But the carbon dioxide scare is proving false - it’s time for some climate sense.
Human activity can never control atmospheric CO2 or global temperature. Much bigger forces are at work – solar system cycles, earth orbital changes, volcanic activity (especially on the sea floor), El Nino episodes, declining magnetic field and magnetic pole reversals, variable cosmic rays and cloud cover, and absorption/expulsion of CO2 by the mighty oceans. Geological records show that today’s CO2 levels are very low - so low that plants grow slower and need more water. Moreover, the ice core records from Antarctica and Greenland show clearly that atmospheric temperature always rises before CO2 levels rise. So rising CO2 is the effect of rising temperature not the cause. Warming oceans are like warming beer – they both expel bubbles of CO2 into the atmosphere. When oceans cool, they take it back. The dense plant and animal populations in equatorial regions shows that humans need not fear global warming – in fact the Russian President has welcomed the possibility of warming for his cold land. We live in a natural warm interlude but we are past the warming peak. There will still be fluctuations and extreme weather events but the next big move will be global cooling – the 11th freeze-up in about a million years. All it needs are oceans heated by submarine volcanoes, and skies made cold by volcanic ash that blocks incoming solar energy.
