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.

Funny thing about an adrenaline rush, is sometimes it increases your co-ordination, strength, and decision-making skills. Not everyone panics and does their best to impede anyone trying to actually triage and fix the situation.

Mean-while, these people are scientists, trying to execute a, frankly, small-scale expiriment to confirm what we already know from an accidental, world-spanning expiriment that was already done over decades. They are trying to do so in a way that, at worst, will do no harm.

... but no, you're right, nimby-ism will save us all.

Save us all? Now who is delusional.

Way to miss the sarcasm. I'll take just about anything between the billionaire's goal of killing not-quite-everyone(which we keep telling them will result in their deaths too, because they are idiots, demonstrating their idiocy by wanting this), and saving everyone.

OBVIOUSLY, I don't expect saving everyone to be an option, but trying is better than the doomer option of saving no-one. Mind you, we're long past the point where many endangered plants and animals could be saved without our help, just in case you wanna play the "but we deserve to die" card.

Agreeing we deserve to die doesn't mean we are allowed to just give up and take down even more entire eco-systems with us.
