Are you familiar with photosynthesis?

Yes but photosynthesis doesn’t generate energy but the opposite: it takes in energy from the sun in order to reverse the reaction

It does generate energy, stored in the form of carbohydrates.

That's a good point, the solar energy is not created. My point is that CO2 can be removed while creating useful energy (in this case, converting a transient source to a durable one). I thought parent was being overly dramatic, even simplistic, in making CO2 sound like some unusable waste product ("burnt carbon. It's burnt. Burnt stuff ain't fuel; it's burnt.").

Global warming is the single scariest existential threat our species has ever faced, and we aren't doing nearly enough to tackle it. Our future descendants will heap scorn and curses on our generation, and we deserve every bit of it. Every politician that refuses to do what is necessary or finds it convenient to play stupid language games about 'settled science' is doing incalculable harm. As citizens, I encourage ev…

> voting exclusively on how credible a politician is on tackling global warming This is really the only important thing that we can do. Except maybe not flying in an airplane, there is little the average person can do in their daily life to inhibit climate change. Whether due to preventive policies or due to resource shortages our lives will change in the near future. Expecting individuals to shame themselves when th…

I agree. Your individual actions won't have much impact, except the aggregate effect on politics.

Politics is so short sighted that unless there's huge pressure from the masses nothing will be done, or just too little too late.

Even if the Science backing up Climate Change wasn't solid, which I think it is, what's the alternative? Take a gamble?

The Roman Civilization probably collapsed because, among other things, the climate optimum they experienced at their peak changed drastically and crops became less efficient. A joke compared to what we might be expecting in a few decades with such an overpopulated and hyper-efficient world, which is really fragile to climatic disruption.

Yeah we will adapt, but not fast enough.

We will. We always do. There is no reason to assume we won't. The wealthy westerners will not notice because of air conditioning and endless bottled water. The less wealthy ones will suffer the heat a bit more. The poor ones will be taken care of. Third world nations will suffer. Some might die. Maybe many. But humanity will adapt. We might lose a few hundred million in the next few decades until their folks find new…

We'll be "fine" if you consider endless resource-based regional conflicts, along with the political upheaval, mass starvation, boosted extremism, and the large scale conflicts that will arise as a result, "fine". We'll be "fine" in the sense that "some human DNA will still be operating in 1000 years". That is a very low bar for human achievement to aim for, and for my children's sake, I hope we do better than that.

This is perhaps the worst, most hubris-filled comment I've ever read on this site. That's not hyperbole, I mean that literally. It is this certainty that fills me with despair for the future. Forgive me if I'm not willing to get into a lengthy debate on the merits of your comment, if that's your starting point then it's hard to believe it's worth the effort.

[Deleting because I don't want to perpetuate apparently debunked climate change myths, sorry, I honestly hadn't seen it debunked.] Dang, my most downvoted comment was asking an honest question about climate change.

If you aren’t a denier then why are you repeating a classic, thoroughly debunked denier talking point? https://skepticalscience.com/global-warming-on-mars.htm

Maybe they honestly didn't know? Hell, I didn't even know about global warming on Mars until OPs comment..

we were doomed and fucked by the 80s

been reading into deep adaptation lately, kinda cool kinda pointless

Maybe we should then consider how to prevent hundreds of millions of deaths in the meantime? Like, the holocaust didn't lead to the extinction of humans as a whole, but there's a good amount of literature around what should've been done differently to prevent it in the first place, and that's an order of magnitude fewer deaths than what you're forecasting.

> The vista had dissolved into an undulating sea of hummocks - waist-high depressions and ponds known as thermokarst. Vegetation, once sparse, had begun to flourish in the shelter provided from the constant wind. I understand the threat. I'm curious why the change described above though isn't somewhat welcome. It would seem that--at least temporarily--areas that are habitable now will become inhospitable, while areas…

here's one reason: when you move north, the amount of sun you get during different times of the year changes a lot. Some crops won't naturally be able to move north.

The oft-quoted opening of David Wallace-Wells's "The Uninhabitable Earth" comes to mind. Reviews have generally only included his first sentence: "It is worse, much worse, than you think." Here is his entire opening paragraph: > It is worse, much worse, than you think. The slowness of climate change is a fairy tale, perhaps as pernicious as the one that says it isn't happening at all, and comes to us bundled with sev…

Curious about what he means by "that wealth can be a shield against the ravages of warming". That is--I can see a case for the wealth of a nation not being a shield for every citizen, but I wonder whether the very rich could weather climate change for a long time. But I suppose that's not the same thing as being totally unaffected.
