Do you know the percentage of people who work at night in USA? Work does not sleep in USA!<quoted text>If anything is less tested than the effect of man made greenhouse gases on climate, feedbacks takes the award. Climate always changes.
<quoted text>The effect of man made greenhouse gasses on the climate is most apparent at night, when people sleep, or at the poles, where nobody lives.
<quoted text>^^^Two thirds of the Northern Hemisphere will experience large stimulation in ecosystem productivity thanks to our carbon emissions. More spring flowers and better crop production over most of our Hemisphere; what's not to love about global warming?
<quoted text>The study is a review of past climate, not an experiment showing the effects of a controlled and known greenhouse gas emission or sequestration on climate. We'll never solve that key problem in carbon cycle research unless we use the scientific method.
You speculate without basis. Spring flowers? WOW! More allergies, haven't you heard?
