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.

Institution: MIT
Lecturer: Prof. David Hsu
University Course Code: MIT 11.165
Subject: #climate #polisci #politicalscience
Description: This class is about figuring out together what cities and users can do to reduce their energy use and carbon emissions. Many other classes at MIT focus on policies, technologies, and systems, often at the national or international level, but this course focuses on the scale of cities and users. It is designed for any students interested in learning how to intervene in the energy use of cities using policy, technology, economics, and urban planning.
