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.

There are no viable solutions under our current economic model unless the problem is solved incidentally to that model, such as renewables becoming outrageously cheaper than any alternative. Otherwise, it’s very difficult to motivate decisions beyond the current quarter let alone the next year or two, let alone decades!

current economic model

This gets tossed around a lot. There are other economic models in use around the world. Are there any studies as to their climate pact?

Edit: In relation to your question, I'm pretty sure that you could find such texts, if you look into Scandinavian relevant studies.

Some other readings would be in relation to Social Ecology


I will not directly reply to your question, but use it as an input to share a couple of thoughts..

The current economic model has infinite growth embedded in it and the planet is finite. In a way, it is expanding in a colonialist manner. Also, it is the predominant one all over the world. This is why we have a triple planetary crises: climate change, biodiversity loss, as well as pollution/waste.

Personally, I don't think we need an economic model to organise societies. We need a societal organisational model, or many actually, that are based on horizontal decision-making processes, as well as sustainability. How to get from here to there, I suppose it's whole another topic.

This is a great question. I do not know the answer, but I would be very interested in seeing such a study.

Countries with proportional representation do better on climate. Two-party systems won’t allow the economic model to shift away from capitalism, that’s why we need to support the smaller parties and independents to actually get things done with electoral reform.
