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.

Then you get into herbicides and pesticides, both of which are majority oil. Even organic products use propane to control weeds.

I don't think they use these two particular things, but different countries have different Standards. If you want to go that route, they also use tractors or other machinery using oil in some capacity.

Which two particular things? Organic farms use propane because they have to burn the weeds, they can’t do it any other way.

[–] Sheldan@lemmy.world 4 points 3 weeks ago (1 children)

There are other ways, in general.

[–] tyler@programming.dev 1 points 3 weeks ago

What other ways?

Propane isn't the problem, at least here in germany. I used burning weeds only for some irrelevant cosmetic weed control.

But preparing the soil was done with a small 2cycles mortiser.
