Something can said to change from a certain standard even if it wasn't perfectly constant to begin with. For example, if I always kept my house at 65-75 degrees for the past year, and now it's 85 degrees inside, I could certainly say that the temperature in my house recently changed and gotten warmer. That might lead me to check whether my AC's working, rather than say "well I guess the temperature has never really been constant, and 85 is within the range of possible non-constant temperatures, so everything's perfectly normal and nothing has changed."
The problem is not that the earth is warming, it is that it is warming at an artificially increased rate.
We (humanity) have gotten comfortable with the way things are, and a change in that is going to mean that things are going to change for us, and we don't like change. Most of our biggest cities are all close to the coast and will be subject to massive flooding in the next 100 years (if not sooner). Much of those same large population centers are also fairly close to being too hot for general survival (without aggressive AC). Our agriculture is all setup for the temperatures we have now, and the rain patterns we are used to. So we are going to have to change both where we live, and how we grow our food (location and probably strains as well).
Global warming is (almost) definitely not going to destroy all life on earth, but many of the forecasts are in extinction-level for most of the large animals. So life in general will continue, and probably humanity (since we are so good at making environment for ourselves), but the (eventual) changes are going to make the world very different, in ways that we are not going to like.
Oh, hogwash. It's not the change as such; rather, lack of control of the change, that causes the blowback.
Thus, the overarching question is: "Who drives the bus?"
Many different groups of large animals have lived and died off over the ages. It will happen again many times after humans are gone.
I personally welcome nuclear war and anything else which will help wipe out the human race. In a few million years the earth will move on to its next rulers and we will be a distant memory.
If you hate humanity, you hate yourself, and that is a miserable way to live. Reprogram your brain, by repetition, it works, and you can find joy.
Not everything has to be doom and gloom. Your life and the planet is what you make of it.
If I pick up your house and drop it two streets over, that could be accurately described as a "location change" of your house. This is still true despite the fact that your house naturally moves some centimeters per year due to tectonic plates shifting around.
Similarly, when global average temperatures saw long term trends of a fraction of a degree of change per millennium, then suddenly started changing at multiple degrees per century, it's pretty reasonable to call that "climate change" despite the fact that it was not completely constant before.
No the pushback is because of money. The words don't matter when so much money is at stake.
Aliens visiting and walking amongst us, building the pyramids etc? I guess the reason is just money /s
And in any case, I assume that conspiracy theory was lucrative for whoever wrote the book or made the film about it.
