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.

Utter tragedy. The worst part about this "discovery" is that we knew it was coming; I've been reading scientists' warnings about how changing ocean temperatures would cause food chain collapses for decades. More to come...

Subplot of "Soylent Green". I used to think it was the main plot, but then learned the problem wasn't Soylent Green or its makeup, but the indifference of the people throughout the movie when they learned things were not as they appeared. Old movie, still applicable.

As a world, we over fish as well. Even if things were not warming we are still screwed because we destroy the oceans.

We really need to stop destroying where we live.

That's everywhere on earth, people carry on about demographic replacement but we should be encouraging smaller populations. Human beings are just so egocentric that the thought of not reproducing is too crazy to entertain.

Not particularly. People who see that their kids are likely to live to adulthood and that they don't need a large family to live well tend to have only 1-2 kids. You see that in Japan, the US and western Europe

in many countries, sub-replacement birth rates have accidentally happened

Gonna be a lot of discoveries like this in the coming years. What a fucking tragedy we’ve made of everything.

It’s not “we.” I don’t control food chain issues, I don’t control pollution and production regulations or war, I don’t get huge dividends from investments whenever a company decides to do the economic thing instead of the ecologically responsible thing. They do it to US. Don’t forget that.

Hey, you buy stuff and didn't recycle every single thing you ever bought (even though most recycling ends up in a landfill anyway) so it's your fault.

I’m literally Satan

[–] livus@kbin.social 5 points 1 year ago

@Jimbabwe yeah, I'm not really enjoying my ringside seat to the destruction and death of a planet. It's going to get much worse.

By "love to eat" we mean need to eat. This is so sad.
