Climate - truthful information about climate, related activism and politics.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

More hopium. We're in that funny period in public sentiment between "climate change is a hoax" and "it's too late to do anything about it". Both are completely incompatible with the amount of societal reconfiguration required to minimize the impacts of climate change. We will not even consider drastic measures until more than half of us are dead. Call it doomerism if you like but that's where we are and anyone taking an honest look at the situation knows it.

The sooner we act, the less drastic the measures needed are. That's the reality of it, and something I'll keep on pushing for.

At this point we need to essentially end human habitatation of +/-10° from the equator, while eliminating coal, oil, and LNG energy use cases, while eliminating migration laws, while eliminating meat production, while investing tens of trillions into moving our farm capacity indoors and rewilding all previous agriculture sites, while inventing and utilizing an anti ocean acidification technology that doesn't itself cause toxicity among marine life.

And we need to some how conince 8 billion people of that during a time when 7.9...9 billion of them aren't financially capable of changing anything in their life without becoming homeless or dying of starvation.

That's not untrue but the problem with phrasing it that way is that people will interpret it to mean we can implement relatively unnoticed measures to mitigate climate change. That may have been true 50 years ago but it's not anymore. Meaningful change will be very painful at this point and that's exactly why it's not going to happen until it's literally impossible to ignore the problem. You would think we're there already but humans are very good at maintaining delusional thinking.

Hardly; it's largely a matter of how quickly we phase out fossil fuels. Wait longer, and you get to scrap equipment before the ends of its normal useful life instead of getting full use out of what you pay for.

[–] krashmo@lemmy.world 1 points 3 days ago (1 children)

We've already waited way too long. That's the point. Talking about it like you are makes it sound like we haven't missed our window for slow and methodical transitions but that part of the conversation happened in the 80s and we decided that path was for pussies. Now here we are in the "October hurricanes are flooding Tennessee" timeline. If that sounds like the right time to be discussing getting the most out of our remaining diesel engines then you're not paying attention.

[–] silence7 1 points 3 days ago

Yes, we've wanted too long for zero impact.

We haven't waited too long to still end up with a habitable planet. Failing to act now puts that at risk.

"We tried nothing and are all out of ideas."

I gave up at this point to have any sort of delusions that we are going to handle this. I do my part, but that's just for my own conscience.

[–] krashmo@lemmy.world 4 points 4 days ago

Same. I do pretty close to everything I can to help but I don't have any illusions that it's going to fix the problem

[–] TheBat@lemmy.world 2 points 3 days ago

I'm doing the best thing I can, which is not having kids.

It's not like women are banging on my door to fuck but my point still stands.

I like the doomer deep adaptation approach. It's too late to stop climate change but it's urgent and effective to reduce it and to find adaptations for it. Infinite hope for what is possible. Mourning what is not possible and burying it and moving on with optimism wherever possible

[–] krashmo@lemmy.world 2 points 3 days ago

I'm with you on that. I'm not giving up I'm just not the kind of person that can ignore the scope of the problem. In fact, I think it's impossible to address the problem without a solid understanding of where we stand, no matter how uncomfortable that may be to acknowledge.

Humanity got a huge bill to be paid, and Mother Nature will still charge us. It'd be an awesome thing if humanity zeroed every single emission and pollution right today (better late than too late). But optimism is not compatible with the size of the climate bill accumulated over decades till today. A alcoholic can stop drinking today, but it won't exempt them from the consequences of having been alcoholic. Sorry if I sound pessimistic, but our past as consumerist humans will still be haunting ourselves.
