No, I’m not Norm, but my husband, the Environmental Scientist in our family says emphatically, “yes”.
I have a very close friend who is an Environmental Scientist. I tell him he's "full of it" when he says that global warming and climate change are man made. Green-house gases are only part of the equation. And man-made is a very very small part of those gases. Man contributes to the greenhouse gases but if our planet had NEVER been populated by humans we would still have cycles of warming and cooling.
PS: Not sure if your husband is a "Climatologist". Only a small percentage of scientists in the EPA are.
It's your opportunity to beat him. Ask your husband if he ever heard of Milankovitch Cycles
Kids in Europe know about it. You can not imagine how anyone speaking about CO2 related warming looks stupid or crooked in their eyes.
Gore made over $100 on this scam so far.
