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.

It’s way more than cars. Plastics, chemicals, energy, shipping, fertilizers, pesticides, even food additives can trace their ingredients to oil and gas. We’ve structured our whole society around oil since World War I, and getting out of it isn’t going to be easy.

A lot of it, is due to having waste products from refining crude oil, which could be turned into something usefull. So when you transition away from combustion engine cars, you increase the costs of other oil based products.

We're still using fossil fuels, and not phasing out as fast as possible.

Doing it as fast as possible would crash the world economy because everything is setup up for oil. So it seems obvious what needs to happen, it’s a different story when you personally are now homeless and you just want a roof and food. We can do a lot better than we are though

The alternative, parts of the world will be uninhabitable. Always gotta think about the economy... no matter how many people this is going to kill, or how much biodiversity we lose along the way.

Is there any point of loss where we will say the economy isn't important anymore, or do we have to be experiencing the loss already?

The problem is crashing the economy will kill a lot of people right now, no need to wait or come up with a better solution
