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.

It goes further back than the 70s.

Climate change was even mentioned in a mainstream movie in 1958. Specifically, “Indiscreet,” a charming romantic comedy starring two of Hollywood’s biggest stars of the time, Cary Grant and Ingrid Bergman.

In this innocuous scene, the two lead characters (Philip and Anna) have recently met and are out on their first date. To break the tense, awkward silence during a painfully long elevator ride, Anna attempts to make casual small talk with Philip.

INT. ELEVATOR:

ANNA: It’s unusual for the weather to be so muggy this time of year.

PHILIP: Yes, I read an article the other day that claimed the world’s weather was changing.

ANNA: Really? That’s interesting.

PHILIP: Yes, isn’t it?

———— Yes, Philip, it IS interesting. And you should’ve shared that article with Anna’s brother-in-law, the diplomat! Then we might not all BE in this situation…Philip! 😡
