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.

Currently about 4.7 tonnes per year is the global average, for americans I found a figure of about 16 tonnes per year. But the second number is probably a few years old.

The average billionaire was estimated at about 8,194 tonnes per year. Or 512 americans. It sucks, but remember that there are way more than 512 americans per billionaire. We all need to change, it's just more extreme of a change the more money you have.

Same with companies. Instead of both sides shifting blame to each other, companies and consumers have to change.

While I agree with your general point I'd like to say that the relation of company emissions with consumer emissions is a bit different, ultimately what we consider consumer emissions are the company emissions of what the consumers buy.

But that still means we need to change both consumer behaviour and laws restricting companies, reducing consumption is important but so is reducing the pollution involved in producing what we do consume.
