In the same time period the number of people has increased in the world from 1.5 billions to over 7 billions. Is it possible that all the paved roads and cut down forests have had an effect on the climate?
The American Physical Society think differently, however, as its public position is:
Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate. Greenhouse gases include carbon dioxide as well as methane, nitrous oxide and other gases. They are emitted from fossil fuel combustion and a range of industrial and agricultural processes.
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 believe that nothing in science is “incontrovertible” thus, in my view, APS has become a political (or religious?) society. Consequently, I resigned from APS in the fall of 2011.
In this talk I will explain why I became concerned about the climate, and terrified by the one sided propaganda in the media, In particular I am worried about all the money wasted on alternate energies, when so many children in the world go hungry to bed.
If you still believe that global warming is occurring and that the main cause is CO2 when I have finished this talk, I urge you to argue for two things to save the world:
1. Introduction of nuclear power
2. Limit the population increase by allowing only one child/woman
