"When all is said and done, more will be said than done".
We are regularly admonished about the "Setted Science" of Climate Change. "Settled Science" is an oxymoron, because it is an inductive process of hypothesis, experiment, result, theory ... test, test. .Not even physics is "settled" by any means. The test case of monitoring the global climate over hundreds, thousands, tens of thousands and beyond is beyond our technical capacity.
Induction is true until it isn't. The Thanksgiving turkey theorizes that humans are benevolent creatures that care for turkeys. Each day, this theory is validated for around 16 weeks. Then it is invalidated, and we have a nice meal with our family.
The rebranding of Global Warming to Climate Change is a superb example of the power of branding. Global Warming is a hypothesis/theory that can be invalidated by data. It is science, just not "settled". Unless our climate would become absolutely static (in which case we would all be dead), Climate Change is unfalsifiable, therefore if you follow the link, you will see it is more similar to a conspiracy theory than science.
We can look at history though, and while history is certainly supportive of Climate CHANGE it is not supportive of warming caused by man. (other than stasis, everything in climate supports change).
History would indicate that we are likely to return to the climate that results in glaciers a mile thick covering much of the populated Northern Hemisphere.
Let's just go with the theory that any warming is being caused by humans though, and this time is different, the warming will be so extreme that human life will be wiped out.
If we believed that, what might we do? A tiny bit of study will show where our current energy comes from.
- Through a combination of some events (eg Three Mile Island, Chernobyl), media nuclear horror movies (The China Syndrome), and the fact that "nuclear" just sounds dangerous, public opinion is swayed.
- As Rahm Emanuel declared "Never let a crisis go to waste". In a crisis, all normal rules are suspended ... see Covid. For government agencies, "crisis" is a good thing. Especially if it isn't real, but most everyone believes it anyway.
- Since Climate change is a conspiracy theory, you can write papers, books, have expensive conferences, get PHDs, awards, be seen as "a really good person", get a ton of investments in technologies that may not be viable at all or extremely dangerous and damaging to the environment (Lithium). etc, etc Hey, no rules man!
