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.

Writing for the majority, Chief Justice Mike McGrath rejected a spate of arguments against the plaintiffs — including that they lacked standing to bring the suit and that Montana’s contribution to climate change is negligible in a global context.

It's not just in sparsely populated Montana, I've seen this ridiculous argument that excuses lax environmental codes because they are a small contribution to a global problem, in Vancouver BC of all places!

Mayor Ken Sim said he would vote against allowing natural gas “if banning it would have an impact.”

“Whether we like it or not, even if we shut down the city of Vancouver it won’t make a difference in decreasing the rate of change of worldwide temperatures,”

Ah the “drop in the ocean” fallacy. “We’re only a small part of the problem so we shouldn’t have to stop being part of the problem”. I see people on lemmy use this all the time when they want to justify doing things that are environmentally reckless.

I remember getting this concept from this (now ancient) reddit post
