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.

Thanks to the relentless burning of fossil fuels, we are — right now, in real time — departing the Holocene epoch, the Goldilocks zone of relative climate stability that enabled us to build the world as we know it over the past 12,000 years. We must recognize this moment for what it is: the beginning of a new era of civilizational retreat, contraction and consolidation. Call it the post-Holocene.

For context, wildfire has been quite rare in the northeast US for the past few hundred years.

One of the Fermi paradoxes/the great filter. Species tend to destroy themselves.
