There is a blinding glimpse of the principal obvious causes for climate change:
Not one Global Warmer has bothered to inform the public where, exactly, Mother Gaia is in these cycles, which operate over 100s of thousands of years.
There are three cyclical factors:
Milankovitch combined what we know of glaciation history with the Earth's position relative to the Sun. The theory has long since been substantiated. For example, as European glaciers retreat, archaeologists discover many pre-historic lost settlements from a warmer era. Oetzi the Iceman was running through an alpine forest, not a glacier valley!
In fact, relative to our position in the Milankovitch Cycle(s), glaciers probably ought to be melting at a FASTER rate than they actually are.
In addition, we are in a period of very moderate Solar Activity.
What it all means is that Earth is in a period during which seasonal differences in the hemisphere ought to lessen, mainly observable in warmer winters. The opposite would be true in the other hemisphere.
To ignore the Milankovitch Cycles and Solar Activity in any discussion of Climate Change makes that discussion specious. To allocate public money to "correct" them, insane.
Ought we to be aware of the changes in Climate and study them? O sure. But while we can react to them, we can't change them or stop them.
In the 1970's and 1960s, many of these same politically correct "scientists" or their teachers were seemingly worried about "Global Cooling." It made it to the cover of Time! The left has succeeded in conflating "Pollution" with "Dangerous Climate Change." "Pollution" is bad. Unfortunately for their case, it would seem that it has nothing to do with global climate changes, which are most likely caused by cosmic events and movements beyond our control. Man-made Pollution an be controlled and we are doing that. Unfortunately, a volcano is also a major uncontrollable "polluter" on a scale that dwarfs human activity. Like a volcano and other geological phenomena, the cyclical progression of Earth's orbits through our solar system cannot be controlled.
The broad outlines of Milankovitch's Glaciation Cycles ought to be at least presented. I will vote ...twice ... for the first Republican who has the nerve to say, "Anthropogenic Global Warming is nonsense."
Amen to that! I refuse to be politically manipulated by politicized "science" that ignores existing knowledge. I've never doubted that some natural warming may be taking place given we're in an interglacial period. But trying to "solve" the "problem" by destroying the American economy and instituting world socialism isn't my idea of scientific rigor.
