...As a geology student and historian, I can absolutely tell you that yes, yes it does exist, and has been practiced on a large scale before. I give several examples in this post which you apparently read in a little over a minute. Perhaps you're thinking of terraforming on a planetary scale, which we haven't done yet?

I'm a fast reader...1K words a minute.
don't care what the text said...geo-engineering isn't possible.
I'm a retired trucker...we're never wrong.

I can't tell if you're being serious or not. If so, would you care to offer some sort of argument about why it doesn't exist, rather than a blanket denial? And the text of this post, by the way, is me writing- if you're going to say you don't care what I have to say, please do so outright, not in such a roundabout fashion.

energy.
consider a boy pissing into a hurricane..
how's that working out? Affect it much?
same thing with humans effect on the environment.
...
am I serious or not?
who knows...I certainly don't.
I do care what you have to say...
but since you post it...it's fair game.

Now we're getting into the complex systems, one of my favorite topics!

Yeah, the amount of energy we exert on the system is relatively small compared to the total energy in the system- but what matters is how and where it is applied. Complex systems like nature are pretty resilient to major shocks to the system- but gradual applications of energy in the long term can have huge consequences. The Fertile Crescent, for example, is largely a desert wasteland today, where it used to be a veritable garden. This massive change was the result of the ancient Mesopotamians over-irrigating their land, resulting in the deposition of large amounts of salt into the soil, shifting much of it into inhospitable desert. And all it took was the relatively small amount of energy that it took to dig and maintain some irrigation ditches.

It's basically like rolling a snowball down the mountain. You only put in a tiny bit of work, but the snowball ends up as a massive destructive wrecking ball. Or like how putting weight on a really long lever can move huge objects. It doesn't take that much energy to cause these changes.

It should also be noted that said changes are really, really hard to stop once they start. Hurricanes are changes in the system that have begun snowballing- that's why they're so powerful and hard to change.

That might or might NOT be the case...I've heard alternate explanations as to why north africa is a desert. I've also heard that the Amazon Basin is was an artifact (1491) during that same time frame...

You're not going to start talking about butterfly sneezes are you?

The Amazon Basin was heavily affected by human activity, yes- (I'm assuming you're talking about the manmade terra preta soil) but the Amazon rainforest itself long predates human activity in the Americas.

the Amazon rainforest itself long predates human activity in the Americas.

how could that be? how could the rainforest even EXIST without the nurturing dust from the Sahara desert?
