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 l's just because no one did a paper on molotov cocktails thrown at oil barons and politicians and their impact on climate

You're seriously underestimating the kinds of things that academia generates

Edit: and yes, the whole thing is meant as a joke. If you're actually using sabotage to reduce greenhouse gas emissions, turning around and selling social permission to pollute is just plain silly.

I love science

This presumes that a vote has an impact.

In the US, right now, who holds power is still decided by who gets the most votes in elections. Even non-swing-states have congressional races, races for state legislature, and elections for local government.

If you're in a spot where you think your local vote won't be close, you can volunteer to turn others out to vote

But a vote doesn't have an impact.

It can certainly happen when things are close, as they are now. Even if all you do is change it from "close" to "not close" the impact is to keep it out of the courts.

It can certainly happen

What can?
