And once we establish the natural effects of solar variability, we’ll realize humans have zero effect on the climate. It’s all about the sun.
But! Scientists gathered at a consortium in Sweden this last summer determined that the sun has no impact on global warming. Scientists came to a consensus, so it must be so!
This is an insane dogma. I know Rush repeats it, but why not? why not? It's presented without justification, and anybody who cares to calculate can see that the rate of combustion of coal and oil is significant on the planetary scale.
One might dispute the nature and extent of the effects, but to dismiss the possibility that humans are capable of producing any such effects, A PRIORI, is manifestly irrational.
Solar activity is EASY to measure, and easy to correlate with “climate change”.
Sunspots are observable, and their frequency is a direct measure of the sun’s output.
Copernicus (I think) recorded sunspot activity from observation, and then later, someone else saw that the reduced sunspot activity he observed correlated with the little ice age of the middle ages.
“And once we establish the natural effects of solar variability, we’ll realize humans have zero effect on the climate. “
I disagree.
I think we will realize that humans have a very small effect on the overall weather, but a larger effect on smaller areas and smaller components of the atmosphere. (what did he say?)
Cities are warmer than surrounding rural areas, but that doesn’t mean that the area above the cities is any warmer or colder than the area above the farms.
We can fractionally alter the formula of the atmosphere by our actions, but it is only temporary, and has no effect on the general adjustment made by a very complex/self-adjusting system of radiation and absorption.
But you are right. It’s all about the Sun.
It is life. Because of it everything on Earth lives and breathes. It’s done pretty good keeping life going for the last kabilllllion years, so maybe it knows what it’s doing.
