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.

From the desert of Phoenix in the United States to the humid streets of Quezon City in the Philippines, mayors are facing the same new reality: Heat is here to stay, and it is impacting every element of city life. That’s why we — along with more than 30 other mayors from C40 Cities, a global network of nearly 100 of the world’s biggest cities tackling the climate emergency — are joining forces to protect our people today and prepare our communities for a hotter tomorrow. Through the new C40 Cool Cities Accelerator, we’ll work together to speed up bold and inclusive climate action that meets the urgency of this growing threat.
