r/climatechange discusses mitigation tech and more doomerism

/r/climatechange continues to attract r-slurs from /r/collapse which is sad because I don't think there's any serious sub to discuss climate change and it's effects on a rational way. The problem is not that climate change is not problem, a 2.5-3C (the scenario we're currently heading) rise above pre industrial levels until 2100 will be dreadful as impacts in agriculture will cause food insecurity in many countries.

The problem is collapsecels taking the most over the top non-scientific claims and presenting them as truth

I think quality of life is going to crash over the next 100 years and long term survival of the human race is 50/50.

>Uhm, end of the century is only 76 years away. What populations do you think will be less in that time? Reducing the population of Gaza by genocide has produced worldwide political effects which will take probably 76 years to play out. You will need the equivalent of Gaza happening world wide for 6 months to reduce world population by 5%. I don't think you will have a single entity recognisable as society that will survive that carnage. Certainly no worldwide cooperation between genocidal warlords will be towards carbon mitigation.

Some say that the warming in the pipeline is enough to send humanity off the proverbial cliff even if we stop all emissions tomorrow. And I'm talking full blown extinction. Frankly, seeing as how it's much easier to stick a wrench in a motor and blow it all apart than it is to build the motor, I think that's absolutely the case. We've stuck a wrench in the carbon cycle and there's no unsticking except MAYBE with miracle level tech like a room temp superconductor. Really want to be proven wrong.

>In terms of raw energy usage growth, if we continue as we have (human or AI & Bots, or both), by 2190s Antarctic ice fields will have all melted. 1000 years from now we will be 18 degrees Celsius warmer. 2000 years from now Earth will become Venus 2.0

Now this guy is talking about runaway greenhouse effect https://en.wikipedia.org/wiki/Runaway_greenhouse_effect

Which no respectable climate scientist claims will happen even in worst case scenarios.

I would not be shocked if by 2030 we're looking into the abyss, so to speak. Climate wise, the 20s may be the last “good” decade for our species.

I'm more concerned with rising ocean temperatures and the effect that would have on the primary source of oxygen. Phytoplankton, what impact will that have because if they go thats it, everything goes. We can exist without sea life, people will miss seafood food but it wouldn't be the end. Lack of oxygen, definitely the end.

Again with the “Phytoplankton is going extinct! We'll suffocate!”, something doubtful even taking ocean acidification in account. https://www.newscientist.com/article/dn28391-oceans-hidden-green-plankton-revealed-by-fixing-glitch-in-model/

Even if that marine doomsday scenario happened plants would still produce oxygen, and even if all photosynthesis magically stoped it would take millions of years for oxygen to vanish from our atmosphere, that's the type of ridiculous scenario they take as truth along with the “we'll turn into Venus”.
