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.

But the good news is that it'll be the coolest year for the foreseeable future 🙂

Not how it works actually.

Okay, within the bounds of your lifetime.

I found the optimist!

Probably the same chance for 2024 with el nino

2025 isn't looking that great either.

The history of temperature rise has not been monotonic. So I'd expect a period of a few years where we don't set a new record.

Yes but that doesn't mean we've reached the current peak yet.

When I see this headline, I always have to try to resist the urge to be like "no shit it's the hottest year on record, it'a going to keep being the hottest year on record cause the planet is getting hotter on average, and we know exactly why that is"

Later: Well technically the average temperature of 2023 was actually pretty moderate, but that's only because the entire world was wrapped in a brutal ice age beginning in December.

Meanwhile in the UK, still waiting for the summer. :(

didn't it hit 32 for like a week straight in September

We do live on an island directly on the middle of two weather fronts.

It’s either cold air from up north or warm air from the med that wins. Usually the cold wins unfortunately.
