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.

2027 has a good chance of being the catalyst that takes us to the after times.

El Nino just ramping up and it's already pretty much the hottest it's ever been globally in modern times.

I'm looking at the weak arctic ice this year, a "super" el nino hitting for fall and winter, weak ice regrowth and a record breaking 2027 summer. I think we will see shockingly low sea ice in the arctic for the next few years and by no later than the next el nino, the disappearance of summer ice completely.

People know things are changing, I wonder when they're going to understand that they will not just stop changing. It's only speeding up. The years will go by, your kids will grow up, and it will not stop getting worse. In fact it'll get worse faster and faster.

But I don't give a shit anymore honestly. Spent 19 years fighting with people about this issue. I'm just focused on my family now, if you want to drive an F-350 and have steak 7 days a week, go right ahead. Enjoy the ride.

Tonnes of CO2e, averages:

 1.60 a roundtrip transatlantic flight
 2.40 one year of car use
58.60 one year, per child you have (dwarfing everything combined in the 3rd graphic in the sidebar)

Shown in the most important chart in human history, because human overpopulation is the biggest and root cause for not just catastrophic anthropogenic climate change, but also the biggest and root cause of factory farming, industrial fishing, unsustainable pollution, biosphere degradation, mass extinction, ...

Fuck you for being alive too I guess. You realize the logical conclusion of your line of thinking is, assuming you believe this to be the correct take, right?
