Nothing ever changes, does it.
This post is an evergreen — if it weren’t for the original date  when I wrote a first draft, it would slip right by as a 2020 post. It has been revised to cover events and changes that have occurred in the past two years — most not much different, only growing in scope and potential damage.
Human movement toward change — including positive change — is as slow as an iceberg moving toward the equator, mere inches over a long time. But see, when that iceberg gets fundamentally changed as they have been in the last 150 years (and most particularly in the last 50 years), you realize that iceberg is a massive change agent waiting in hibernation until the conditions are ripe for it to melt faster than before, even since the 1800s, the earliest start point for our warming trend.
Whether human beings are willing or able to do something extensive enough to slow the trend down, it is likely there will nonetheless be movement toward increased temperatures, though more slowly if some action is taken. With changes in energy use, flora and fauna will have more time to evolve into beings still capable of maintaining a manageable life without an immediate disaster hitting.
That also goes for human beings. Humans, of course, don’t necessarily need to physically evolve to survive. They can figure out ways to make the insufferable sufferable again. Sometimes, tho, given what we have learned of how all of our machinations toward surviving in a changing world, it may be BETTER to go backward, to devolve, so to speak. A bit anyway. There are so many things that humans don’t need that they buy at exorbitant prices just to compete with their neighbors, showing off their superiority because they not only have plenty of things, they have far MORE than they will ever need in a lifetime.
Look at the head honchos who run massive conglomerates and take in more money in 10 minutes than they could possibly need in 10 lifetimes. A few could toss a billion [or more] dollars into an easy-to-access container, and tell people, “have at it!” They would still have a few billion more.
