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.

They also made a web app where you can input any city and it will show you its 2080 analog: https://fitzlab.shinyapps.io/cityapp/

Cool idea, but outdated and pretty inaccurate for a lot of areas unfortunately. I’ve seen a few better versions out there.

Do you have some links?
Maybe also something that's not just US only? :⁠-⁠\

I’ll see if I can find what I was looking at. I haven’t seen a really perfect one though. If you want to answer a specific question about your future climate, it’s often best to just look at local predictions.

Thanks for the effort already! :⁠-⁠)

I think this was the best one I had found: https://climate.copernicus.eu/climate-analogues-finding-tomorrows-climate-today

Unfortunately it appears to be broken at the moment. Hopefully that is temporary.

That’s pretty nifty and easy to interpret

And they use OpenStreetMap, pretty cool
