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.

"If everyone had emitted like the bottom 50% of the global population, the world would have seen minimal additional warming since 1990,"

The study assesses the contribution of the highest emitting groups within societies and finds that the top 1% of the wealthiest individuals globally contributed 26 times the global average to increases in monthly 1-in-100-year heat extremes globally and 17 times more to Amazon droughts.

The research sheds new light on the links between income-based emissions inequality and climate injustice, illustrating how the consumption and investments of wealthy individuals have had disproportionate impacts on extreme weather events

Our study shows that extreme climate impacts are not just the result of abstract global emissions, instead we can directly link them to our lifestyle and investment choices, which in turn are linked to wealth,"

If all the poor people drop dead tomorrow, the emissions will change. And the number of animals will decrease.

You do have an impact. It is no negligible.

It is not sufficient to cut the emissions of rich people to zero. It is necessary and the majority, but all of us need to stop putting GHG into the atmosphere

Right, but I'm not all the poor people. And I can't control them either. Yes, if everyone stopped eating meat, we'd stop farming them and emissions would drop. But that's unrealistic, never gonna happen. So yes, my impact in negligible.

And I'm not saying I won't do anything because my impact is negligible. I still recycle and encourage others to do the same and so on. But realistically speaking, I'm nobody. What I do doesn't change anything. At most I may have influenced 10 other people to be eco friendly. Still didn't change anything in the grand scheme of things. But maybe once a few more million people do the same we'll be ok. We'll see.

That's exactly what the coal company said about the oil company.

I do agree we need to tax meat and subsidize cheap proteins like beans, tvp, and seitan

No, this is what those companies said and did. Let's not pretend they're powerless, lol.

And let's not pretend you're powerless
