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.

Taking Big Oil to court for 'climate homicide' isn't as far-fetched as it sounds (grist.org)

If you agree they've been lied to for decades since the 70s, how could they could they also know for 50 years?
That seems contradictory.

Climate change has been in the public discourse since at least the 80's, so legislators did know. It just hasn't been in their interests to acknowledge it.

The Venn diagram of public discourse and legislator knowledge isn't a circle.
And the public discourse was filled with FUD from Big Oil, no place more so than the halls of congress.

I understand your point but let's not ignore that fossil fuel corporations have made campaign donations and contributions to legislators for as long as those corporations existed. Whether or not legislators totally bought into the FUD (and I'm not sure all did, the same way not everyone in the wider public discourse bought into it) it was literally not in their interests to legislate against fossil fuel.

So, yes, we should hold them responsible.
