These clowns pushing "The Green Scheme" have their heads where the sun does not shine. The push to reduce emissions is to be admired, provided the result is attainable. Carbon or CO2 is not the evil in the room causing global warming or climate change. Earth has been slowly warming just a few degrees since the end of the iceage. The progression is like a slow motion spring in the northern states. Right now the daytime temperatures are slowly climbing. Snow in forests is barely starting to melt. It is melting away from tree trunks which the sun can warm. Snow and ice reflect the sun's rays back into space. Once ground is visible, the heating accelerates.
