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.

A real oil CEO horror story.

Meanwhile, Exxon sues shareholders for wanting more green initiatives https://slrpnk.net/comment/8757029

Imagine owning a big share in an oil company and then being all shocked Pikachu face that they're not in any way sustainable. Just divest already

No, that's the opposite of what I want to happen. If they "divest" that means they're selling their stake in the company to someone else, who likely cares less about climate change. The company stock doesn't just disappear. Shareholders are the only ones in our current system who can have a meaningful impact on companies they own shares in. The people who hold companies to climate expectations are exactly the ones I want holding stock in those companies.

Oh, I agree. I was deliberately talking in investor terms because it's people who invest professionally who are being disingenuous here

I'm not very familiar with how public companies work, but I'm surprised that a shareholder with only 3% of ownership can make such demands and can excel such control. I understand they're the largest shareholder, but I could imagine a large portion of the remaining 97% would pay for now following the Paris accords since it may main less money for all investors on the future.

A recent study (still in peer review phase last I saw but the people who wrote it and good work) showed that the 1C rise in temperatures vs pre-industrial times (which we're already past) lowered GDP by 12% or more globally. The current 3C that many climate scientists are warning we're on track for could lower GDP by 50% or more.

Not following the Paris accords or stricter is actually going to hit stockholders hard if the study is accurate.

I guess it feels surprising they care about long term problem vs ignoring that for short term profit

[–] mynachmadarch@kbin.social 2 points 4 months ago

That's the part that I'm banking on, that 12% has already happened. That's 12% they've lost out on in the short present term. I'm hoping they see that and decide they want that money back. I know they're probably doing a cost benefit analysis of cost to combat climate change versus potential lost GDP. But still, I'll take any arrow in the quiver against them.
