So unless you are disputing that a large worldwide increase in greenhouse gas concentration in the atmosphere affects climate, your position that humans can't affect global climate is untenable.
Global warming is like having cancer. You go to the doctor( or scientist), you check if you have cancer (or global warming), he tells you yes you indeed have cancer and only 5 years of life left (a few decades with global warming) and if you get treated right away they might even prevent the cancer from spreading and you will have a good chance of growing old and dying in your 80s. Except you are stingy and don't want to pay the (very cheap) bill. 3 years later you are bedridden and the bill has quadrupled.
Also if you think climate change wasn't accelerated by humans then please take a look at this nice chart. https://xkcd.com/1732/

True, all of these things are out of our control and also not currently happening. Climate change is and we can also do something about it.

Ehh sure, this and the above paragraph are prime examples of what-aboutism. This is generally not useful for solving problems.
> I am yet to be convinced human beings are responsible for a changing global climate. Global Climate Change is a thing, yes, and that climate has been changing since the formation of planet Earth 4.54 ± 0.05 billion years ago.
Yes the climate has been changing. It generally did not change at the rate we're seeing now. It might not be manmade but that would make timing (right after the industrial revolution, coal power plants, plastic, etc that all happened at a __very__ large scale recently) a huge coincidence.
I don't think humans can possibly affect this planet in terms of /global/ Climate Change in any measurable magnitude. There are forces which affect and cause /global/ Climate Change which are vastly more powerful than us mere humans.
Maybe it helps to think about it like that; Humans aren't changing the climate - you're right. But corporations are doing it to satisfy human demand. While corporations are run by us they exhibit vastly different behavior as well as operating at a completely different scale than us.
> Humans can affect their local climate for sure - a city has a different local climate compared to an equivalent area of wildland. All that tarmac and concrete does have an effect locally. But to suggest that the human race - which inhabits a small percentage of the landcover of a planet of which two thirds of its surface is water - is the main cause of Climate Change, reeks of hubris and agenda.
We use most of that land cover for agriculture and changing it by deforestation etc. The water parts of earth are.. Well I don't really see your point there. 1/3 is a looot of area to affect, surely enough to change the climate by a tiny bit (2 deg) which then causes runaway effects. It throws the system off balance.
> The best thing we humans can do is to put things into perspective, deal with a dynamic, ever-changing global climate which is out of our control, try our best to keep the place tidy - we do need more effort on that front - do what we humans are great at doing which is coming up with great and new technologies (I'm looking at you, fusion power to be a workable thing within my lifetime!), and make the most of our individual limited time on this Earth by following your aspirations and fulfilling your potential.
I think you're right here. In the end it doesn't after what causes climate change anyway - it is happening and it is killing us so we need to do something about it. Thing is, if we don't know the cause for these extreme rates this will be hard. Humans seem like a very likely cause here and the specific sources (e.g. coal, flying) are conveniently in our control. So even if you're still not sure, acting as if we're the cause is a good action plan, don't you think?
While the "it is happening" part has good amount of supporting data and is almost certainly true, the killing us part is much more questionable, most predictions agree that if we do nothing it will cause <10% gdp loss in 2100 compared to the scenario where it did not happen. So we need to make sure that whatever we do to prevent climate change doesn't cause more economic loss than climate change itself, and mostly invest in developing new technology and helping poor countries to become richer.
Maybe we keep SA and the northern bits like Tunisia etc.
Global GDP probably declines less than 10%, right?
You can't reduce everything to money in these terms.
- An asteroid could wipe out all life on Earth. - The supervolcano known as Yellowstone might erupt.

And this is 100% going to happen: our own life-giving star, Sol, WILL destroy the planet in a few billion years time.
Also 100% going to happen; you will die at some point between now and the next 70 or less years, depending on your age, genetics, health, propensity for dangerous sports or activites, whether you look out for fast moving vehicles whilst crossing the road, whether or not an aircraft falls on you.
And so on.
Of course, we humans should try and keep Spaceship Earth in good running condition. Finding ways of reducing waste and keeping our environment clean and healthy is of utmost importance.
As for Global Warming?
This is where I trigger potential downvotes - please don't do this just because I might disagree with you, it's just not cricket old bean.
I am yet to be convinced that human beings are the main cause of Global Warming. This has, despite any protestations to the contrary, not been proven. Global Warming theory is still just a theory, and just to head this one off at the pass, no, pointing out that "gravity is also just a theory" is a fallacious argument.
