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.

The man doesn't know the price of groceries. He's completely detached from society and real life.

The climate catastrophe is a whole fuckload of problems caused by humans changing the climate. It's not just "it gets a little warmer" it's death of habitat for various species, it's ocean acidification, it's weather changes, it's crop failures.

It'll lead to things like mass migrations of people from places that are no longer habitable due to a loss of access to water or food, or because their homes get flooded or destroyed by severe weather. We might see camps as massive populations migrate, there'll be infrastructure problems. We'll see starvation, and disease, perhaps another pandemic.

As people migrate to other places there'll be border disputes, xenophobia, increased nationalism. We might even see people get shot as they're trying to enter other countries, it's not like we don't see that already.

The problem isn't "it gets a little warmer" is everything else that follows.
