I am trying to engage you. But you have no answers. So you turn to condescension.
So I win. Man is not the cause of climate change on Earth or Mars. The Sun is.
Is your premise that the Sun is providing more intense radiation than it was several decades ago and that is the cause of global warming on Earth, and Mars, and Pluto? If that is the case it should be relatively easy to measure the change in energy being released by the Sun, and if it is changing the temperatures on Pluto it is going to be pretty obvious in the Earth to Mars orbits. The surface temperature on Pluto is near minus 215 degrees C. Absolute zero is minus 273.something. How much has Pluto warmed in the last few centuries?
Also you conveniently revert to the black and white, humans are doing it or nature is doing it argument. No one realistically believes humans are doing it alone. But, we can control the human contributions, and we cannot control the unknown natural cycles that our influence is superimposed on. Yet, anyway.
So, the objective is to start. While many of you would like to believe scientists understand a lot more than they do, and that there should be some acceptance criteria for accuracy of the scientific predictions that you can hold people to, I would venture that scientists on the whole are much more meticulous and rigorous in their prognostications than say, lawyers are. Or businessmen are. Because lawyers and businessmen get to work in an environment where all the rules are essentially man made. When the rules are man made, your objective is to bend or break the rules to your advantage. Science has no such zone to operate in - either you are within the rules of Mother Nature and your "theory" works, or you aren't and your theory fails. In most cases the links between knowledge of the sicence and practical application of technology are almost vapor. Yet, by applying the scientific method, and by using sound engineering principles, things like the bearings in your engine actually work reliably enough that we find them "practical." If held to the standard of being understood well enough to satisfy your willingness to latch on to global warming before they were used, fluid film bearings would be in the laboratory today.
Get a grip on reality. We don't know jack shit about how the Universe works. We know what we need to know to survive. Somehow, when it becomes necessary to know something for human survival, the secret is revealed to humans to the point where the new knowledge can be exploited to improve the statistics for survival for one person or a clan, or a nation. Once the advantage has been realized, the search for knowledge is typically abandoned. Jim
