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.

I'll note that 2.5°C of warming by 2100 is a significant improvement over the trajectory we were on a decade ago, even if still far from where we need to be

“I expect a semi-dystopian future with substantial pain and suffering for the people of the global south,” said a South African scientist, who chose not to be named. “The world’s response to date is reprehensible – we live in an age of fools.”

jesus christ :-(

In Córdoba Argentina weather has been getting crazy these last few years. We've been constantly getting 40°C+ temperatures in summer, an even in winter we've hit the 40°C mark (in the middle of July, mind you). Last year we only had like two days in the whole year where we managed to get minus 0°C temperatures

Almost 9 fucking months of summer here in Perth, with about 3 of those months being 30C and clear every single day. Forests and bushland are dying as a result, and water is scarce. I've never seen anything like it.

That's 104° F for anyone wondering

I don't mean to downplay the situation at all but doesn't that description pretty much match the world as it exists today? If anything I would expect their predictions to be more dire than that. The global south seems to have more than it's fair share of pain and suffering already.

Oh sweet summer child...just wait. It hasn't even begun to get bad.

Oh I know. I'm just saying I don't think this particular quote really communicates that fact. It could just as easily be describing any point in the last 200 years as a future impacted by climate change.
