Climate - truthful information about climate, related activism and politics.

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.

We have vegetable oil for example and algaes can produce oil as well. So we do not need to dig for fossil fuel, there are alternatives for lubriaction and similar problems, were oil is very much needed.

Im not certain how well plant based alternatives work for the specific formulations needed for most lubricants, but honestly given the scale involved it doesn’t really matter if we use ground reserves. Most machines use gallons a year or decade, not per five minutes like cars.

Yeah, it's the mechanical properties of non-crude lubricants that's the issue. Maybe scientists could find a way to turn vegetable oil into industrial grease, but I have no idea if that's even possible.

But like you say, lubricants aren't the main problem; it has always been fossil fuels.
