You may also already know more about the subject than the phalanx of United Nations and Government of Canada scientists who have lately been frantically warning about greenhouse gases. It doesn't require a genius IQ to figure out it usually gets no hotter than mid-afternoon on a clear summer's day, nor to figure out why. It's the sun. Solar radiation absorbed by plants permits photosynthesis. The energy stored in coal and oil originates in the sun.
Air masses move and rain falls because of solar radiation.
I can't help thinking their motives are political. Government can't control the sun. Most government climate scientists are suspcious of the free market and generally leery of industry. All preserve government's place in the economic driver's seat. Big business is the cause.
