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's still more than 10 years from now!

Let's cross that bridge when we get there, what do you say? We have bigger fish to fry than worry about something more than a decade away.

So what's going to take us out first? Water wars, insect collapse, ocean warming, climate change, forever chemicals, micro plastics....

[–] original_reader@lemm.ee 7 points 3 months ago

...pandemics, nuclear war, biodiversity loss, resource depletion, cyber warfare, antibiotic resistance, political instability...

Spoiled for choice here.

It's also possible that we start working together to prevent those kinds of outcomes.

Maybe the rise of fascism or demographic collapse

What exactly would the collapse cause? Article mention polar ice creeping up to northern England, and temperatures dropping. Would it mean that you'd basically get ice age in half of Europe? How I understand it, you'd gat extreme cold in the north, and extreme (not survivable) hot around the equinox. So, mass migration from both into the central eruope, where the weather would be extreme hot but survivable in summer, and super cold in winter? More storms, typhoons, and in general a really bad time, due to drought and crops gerting fucked?

I am ready to toast the end.
