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.

So, the study theyre citing is pretty flawed. It starts with an assumption that emissions strictly correlate with income, it doesnt actually break down or analyze emissions sources. It just takes the total emissions of a country and divides that up by income. Its economic analysis. But that's not how emissions work. A million dollar car isnt gonna emit 100 times more than a 10k car. The cows for their wagyu steaks arent producing more methane than cows ending up at Mcdonalds.

The wealthy absolutely emit more through flights and boats. Someone with a private jet is likely emitting hundreds of times more emissions than a regular person. But theres not that many private jets. Ban all private jets, but it wont even register on global emissions totals.

There's a ton of academic research showing the correlation between income and emissions.

There are also a ton of actions which are necessary to get to zero emissions but not sufficient. Banning private jets is one.

Mostly it is bigger houses, driving bigger cars, flying more to vacations and well buying more in general. We are talking about thte top 10% globally here. They are not crazy billionaires and most do not own private jets or boats.
