"Here's my problem with the argument. It's been pointed out with charts etc, that illegal immigration is at a low point right now, relative to the past, so it's not really a problem and nothing to worry about apparently. Yet climate charts show that CO2 levels are low right now, relative to the past, and yet it's an immediate danger that's going to destroy the planet. Umm, ok?"

Have we always known what the climate used to be? Did we always know how far back humans go? Do we still know for sure? If we really are the latest and greatest type of monkey, ape, whatever, then how far back do they go and what was the climate then? What were they before they became monkeys? Could humans have lived in those conditions back then?

Well one way or another the kinks have to get worked out. You can't honestly believe when science makes a prediction that the large majority of the time when put into practice it works perfectly as intended. That's how the tests are done though and have been in the past. If you can't verify it in different set ups then it can't be fully proven. This sometimes is a major headache and a major undertaking but needs to be done to legitimately prove the method. Analysts and experts aren't always scientists and don't always use hard science to come up with their results either.

I'm not the one who brought science into this. I also said the planet not humans. We're working on Mars so is Earth necessary in the future if we can live elsewhere? Since we're talking about the future and what could happen and all.

I'm at the verge where I'm not certain I can take you seriously any more. Either you throwing things out in jest or you simply don't know.  If the former, we're done, if the latter, I can educate you if you're willing to listen.

Do we know historical climates?  Yes. Climates leave their marks all over the place.  Ice cores, geological strata, fossils, etc...  There are many ways to detect and correlate various data to determine historical trends in climate.

Do we know how far back humans go?  Yes.  Various species of humans in fact.  As for our ancestry with apes, we shared a common ancestor.  We did not evolve directly from apes (monkeys are different from apes....you can tell which is which because monkeys have tails). Could modern humans have lived in those conditions? No.  Neither would our food (meat, fish and crops). That's why things evolved....adapted to fit in with the changes. The problem now is that the climate is now changing at the pace it used to.  It's not slow enough for adaptations to keep up.  We're also a much more populated planet today than even just 200 years ago (1 billion vs 7.5 billion today).

Do we intent to colonize Mars?  Yes.  Will Mars be a suitable habitat for 12 billion people in the next 100 years (current population projection)?  No, not even remotely close.  Nor will we have to means to transport that many people.

Same here since I'm wondering when we're going to get back to the original topic of paying for the wall but it seems you want to stay away from that.

I didn't question the climate historical data.

We only know based on what we've found, and to assume we've found everything is one bold assumption. How do you know for sure that we couldn't have lived in those conditions? There's been plenty of change already and we're still here. If it's tech that's aloud us to survive, then why can't it continue to based on it's ever rapid innovation and evolution?

How do you definitely know there will be 12 billion people in 100 years? Why will it be around 100 years before we can live on Mars if at all? I thought we only had 12 years? The expert scientists told us all so already.
