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.

A global average is just that: a global average. Some places are hotter, some colder. Not every place sees the same things at the same time.

Oh yeah i’m not saying it’s not hot elsewhere, I just don’t understand why it suddenly seemed to switch. Could just be a fluke I suppose.

It's the wavier jet stream that's causing the sudden switches. You either get really hot or cool and (often) wet depending on which piece of the wave you're on

Ahh that makes more sense, thank you!

it’s not

unstable weather patterns will be more common
