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.

Climate change is commonly treated as a single, global problem that needs to be "solved." This mindset may have been appropriate in the past, but at 1.5°C above the preindustrial average, it's clear that we are not going to solve climate change. Everyone is going to live in a changed and changing climate for centuries to come. In this powerful keynote session, Spencer Glendon, founder of Probable Futures, will show how essential it is to make adaptation a priority and how doing so can lead to stronger institutions, healthier communities, better food, and even more effective decarbonization. Whether you are interested in housing, transportation, water, insurance, community organizing, fruit, or any other aspect of society, this session will give you frameworks, tools, and examples to help you see the world around you more clearly and make better decisions.
