And.... fossil fuels are 'wrong' because.....
Oh, yes, apparently CO2 controls the climate. But not just normal CO2. No. It's the evil man-made CO2 that's really causing the damage.
Problem is, CO2 doesn't control the climate. If it did, well known scientifically established periods such as the Medieval Warm Period, the Roman Warm Period, the Minoan Warm Period, etc., where atmospheric CO2 concentrations were considerably lower than they are today, simply could not have happened. But they did...
To take an example, during the Roman Warm Period, global temperatures where around 3 to 5 degrees Celsius warmer than they are today. And yet the amount of CO2 in the atmosphere was under 300 parts per million [ppm]. Today it's about 420ppm. So if it was warmer in the past when atmospheric CO2 levels were less than today, how does CO2 control the Earth's temperature?
You may be unaware, but CO2 accounts for 0.04% of the atmosphere. Of that 0.04%, the burning of fossil fuels accounts for around 3%. Therefore, 97% of all atmospheric CO2 is natural – it is the out-gassing of oceans, volcanic activity and the decomposition of plants, etc. The relatively tiny amounts of CO2 emitted by the totality of humans through the burning of fossil fuels has an almost insignificant effect on the planet.
