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,"

No. It's not 2/3 of climate change caused by wealthy bastards, it's 100%.

Non-wealthy people don't own factories spewing heat and trash into the air. Non-wealthy people might own cars, but they don't design and build those cars to constantly spew dangerous & deadly emissions โ€” wealthy people are responsible for that, and for the lack of a healthier, greener choice for transportation. It's wealthy bastards who've fought against regulations reducing pollution, wealthy bastards who oppose public transit, and wealthy bastards who profit from the climate change that'll eventually kill the rest of us.

Fuck if I'm causing 1/3 of climate change. Fuck, no.

Wealthy bastards make sure environmental protection is a punchline, and wrap everything in plastic like Laura Palmer. The rich are at the heart of every vile thing that's being done to the planet. Virtually all of man-made climate change is caused by rich bastards.
