Because of the following statement from the American Physical Society:
“The evidence is incontrovertible: Global warming is occurring.
If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.”
I resigned from the society in 2011. First: nothing in science is incontrovertible. Second: the “measured” average temperature increase in 100 years or so, is 0.8 Kelvin. Third: since the Physical Society claim it has become warmer, why is everything better than before? Forth: the maximum average temperature ever measured was in 1998, 17 years ago. When will we stop wasting money on alternative energy?
