The Carboniferous Period, about 360-290 million years ago, saw early wood-producing plants grow, multiply, spread and die, taking carbon dioxide from the atmosphere in great quantities. That plant material did not decompose, and over millions of years dead and unrotted plants stored so much carbon the atmospheric carbon dioxide levels reduced and the planet entered a cooking period, into the Ice Age of the Permian Period. This is historic fact! Easy to verify, simple to check.
How does one check the ‘modern scientific studies' theory of ‘carbon capture' and ‘global warming' based on academic theory, with no practical measurements? And, contrary to history?

The Glasgow conference on Climate Change was held earlier this year during the coldest weather since 2007 – so 15 years of no change? Were the Thames to freeze, as in Samuel Pepys day, would that prove or disprove the theory? In whose opinion?
