I think people are missing the point, it's not about who survives, it's about who dies and suffers.

If I told you (made up numbers) that in the next 50 years, 100 million people will die an average of 20 years early because of climate change. Sure, 100 million is just about 1.3% of humans, but it's still 100 million people, who will die at 50 instaed of 70, or at 25 instead of 45, these are people who will probably die from heat, from natrual disasters, from famine, from poor health as economies collapse.

We won't be fine, someone will be, but WE, as a group, won't be fine.

In fact, we are already not fine but it's mostly felt in poor contries.

Not to kill the mood but the harsh truth is that the generations before us doomed a lot of us, and the current generations are just starting to get it, and future generations will truly feel the ignorance of our past and the indifference of our present.

As long as climate change doesn't happen "too fast" (values of "too fast" may vary), we will engineer our way around it.

While this is true, we must also take into account who exactly will benefit from that engineering and survive. Not everyone will be able to take advantage of non-global engineering solutions, and just like with every technological advancement, the differential will be used by those "with" to subjugate those "without."

Are you actually a scientist?

Air Conditioning to mitigate climate change? That's like dowsing a fire with lighter fluid.

And you think we'll be able to out engineer the sun? In 250million years we will not be here guaranteed, and if somehow we make it it won't be in any form we know as human.

The thing about humans are: we are frighteningly clever

Let me introduce you to Facebook.

Dude, shut up, I'm trying to doom scroll over here .

I do agree that we are very inventive, capable and imaginative when it comes to solving great problems.

Unfortunately we are also capable of becoming very destructive, ignorant, selfish and absolutely brutal to one another especially under a lot of stress and anxiety.

My greatest fear in the coming decades is mass migration and entire populations of people moving to places where they won't be welcome, and people in places where everyone is relocating to worried that it will engage endanger their survival. The biggest problems we'll face won't be environmental... they will be political and social.

2/3 of humans dying is also unlikely.

So much of our modern economy is rooted in assumptions about where and how to mass produce food stocks. Climate change threatens all of that.

Obliterating breadbasket regions in Egypt, Jordan, Iraq, and Iran would devastate the regional populations.

Then you've got the wars in places like Ukraine, Lebanon and Sudan, further strangling access to fresh food stocks.

People joke about the looming "water wars", but consider how much Israel and the Saudis have invested in desalination and what dehydration is doing to the million plus Gaza residents who have lost access to reliable drinking water.

What happens during a substantial crop failure in the South Pacific? It isn't as though India and China haven't experienced massive famines in living memory.

You can argue the finer details, but it is easy to see a scenario in which a billion or more people are wiped out over the course of a generation, because of substantive shifts in access to basic living needs.

Antarctica mostly

Antarctica. If you know you know.

You say that but the ozone layer hole actually started to grow again in the past few years.

Tell that to someone living in rural India or China in the 90s
