A hypothesis has been put forward (no, not that CO2 has a warming effect: that&#x27;s physical fact. It&#x27;s the extent of that that is in question): no mathematical function has been found to fit the observed data. Fact! Conclusion: the situation is much more complex than we currently understand and does not support the horribly destructive policies which are very much in the interests of a clique of politicians and folk with dependent jobs.<p>You again use the word &#x27;deny&#x27;. Bruno Giordano and Galileo would understand that word entirely. Giordano paid the price for that by being burnt alive and Galileo saw discretion as the better part of valour. We can see that the use of the word reveals this is a religious debate.
