It all seems so futile.
Since 1750 All of Mankind's CO2 inputs have increased the CO2 in the atmosphere by barely a 1/10,000th part! What on earth are these silly Green people trying to do?
ref. "Currently CO2 occupies only 1/10,000th more of the atmosphere than in 1750, Keeling & Whorf, et al. 2004"
Aircraft contribute such a small amount in reality but politically it seems they are choking the planet!
Why change anything for politicians whims?
