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.

That means that all the memes and jokes and films that we love to share with friends and family – from “All your base are belong to us”, through Ryan Gosling saying “Hey Girl”, to Tim Walz with a piglet – are out there somewhere, sitting in a datacentre, using up energy..."

Why the fuck are they posting this bullshit? The cost of an email include the cost of the device you use to send or read the email, which is 70% of the cost. Then it's 15% (energy wise) to transport the email. The cost of storing the email is 0.5%.

With that in mind, think about how much it costs to watch 1h on YouTube or Netflix...

Some explanations in French (sry):
