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:

Climate activists disrupted a DNC-adjacent event sponsored by ExxonMobil on Wednesday, the same day that Minnesota Governor Tim Walz formally accepted his nomination as vice-presidential candidate for the Democratic Party. Walz has faced harsh criticism from Indigenous and environmental rights groups in Minnesota for his authorization of the Line 3 oil pipeline through Native treaty lands in the state. We host a roundtable discussion on the climate crisis and the Democratic Party’s response with Ojibwe lawyer and founder of the Giniw Collective Tara Houska; climate organizer Collin Rees, who was part of the ExxonMobil action at the DNC; and climate scientist Michael Mann.
