The Soot Experiment
Global warming alarmists want us to believe that CO2 concentrations are rising, the rising CO2 is causing the atmosphere to warm and the warming atmosphere is causing glaciers and ice caps to melt.
However there is another mechanism that can melt snow, ice, glaciers and ice caps- soot. Get the reflective stuff dirty and that dirt traps the heat from the sun's rays.
There was a show on the Discovery Channel about global warming- a pro AGW show. One scientist was in the Arctic demonstrating the albedo effect. Below freezing temps and nice white snow. He then laid down two 2'x2' pieces of cardboard- one was white and the other was black. The white one stayed the same as the ambient and the black one rose to over 90 degrees within a couple minutes.
He wanted to demonstrate that having no Arctic ice cap to reflect the sun's rays then that will add to the over all global temperature.
What he demonstrted was that dirty snow gets warm and warm snow melts.
So this is what I did. I took the ash from my pellett stoves and spread it over my unshoveled back walkway- over two feet deep. I did it half way down, leaving the other half pristine white. That was a few weeks ago.
Now the sooted half is melted down to the walkway and there is almost 2 feet of snow left on the other half.
Exposed to the same temperatures, exposed to the same amount of sunlight, the sooted half melted so much faster it is easy to conclude the cause and effect relationship.
The point being it isn't the CO2 and by focusing on CO2 we are missing the root cause.
Take a close look at glaciers. Find one that is pristine white and melting. Good luck finding one that white.
