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.

"What makes a transition just is far from a given [...] For an energy transition to be just, injustice must be eliminated, not merely displaced."

"For instance, a major scaling up of solar panel production with exploited labour or outsized damage to particular communities and ecosystems does not represent a just transition."

"Similarly, decarbonising energy systems in the Global North while the Global South remains underdeveloped is not a just transition. Rather, the project of advancing a just transition is transformational – moving from a world built around extraction to one built around regeneration and care, and a future where people can thrive in a world that is more just overall."
