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:

Istanbul's Caferağa neighborhood has a longstanding reputation for its cultural richness and historic charm. Quaint cafes, restaurants and bars line the sidewalks. A thriving arts scene draws an eclectic crowd. More than 2.3 million visitors daily flock to the district in which Caferağa resides — but it's overwhelming the neighborhood's small community of 22,000 residents.

The overall message here I think is: action is still necessary, but the reality is that we're too caught up in politics and economics and we missed our chance at mitigation. Now we need to look to how to cope with what's coming.
