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.

A recent study has found that the richest 10 percent of the world population are responsible for two-thirds of observable climate warming (futurism.com)

btw the top 10% is 800 million people so if you're from the west you're more than likely part of that figure.

doesn't mean it's your fault but if you're not actively doing something to prevent it then you are part of the problem..

Copied from reddit comment

According to https://wid.world/world/#tptinc_p90p100_z/US;FR;DE;CN;ZA;GB;WO/last/us/k/x/yearly/t/false/0/200000/curve/false/country , the global 90th percentile income threshold in 2023 is at about $46,7k USD, market xchg rate.

But of course it's likely that if you are from the US your car use and shopping habbits contribute more even if you are below that income level compared to say a European who drives less and buys less.

I have a feeling even the bottom 10% of Europeans are still contributing more than the bottom 10% of someone in India or Botswana. This Wikipedia page says that the average EU citizen contributes 117% of the global average carbon emissions (for comparison Canada is 307% and USA is 285%).

I like to think of it in terms of fault vs responsibility. It’s not our fault, for the most part. But it is our responsibility to do something about it!

I’m hopeful. Renewables are exploding in growth.

I also like to think of it in terms of necessary and sufficient.

Its not sufficient for you to avoid buying petroleum/plastic and animal products, but it is necessary.

Yes a very good point, the carbon footprint of the average Canadian is 10x that of the average Albanian.

I knew they were up to something 🤔
