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.

I don't think it's advisable to run both at once. Maybe if your cooling system was set up so the AC was cooling the pre-cooled air from the evap cooler? Perhaps then you could achieve lower temps with a little less energy, but it would likely take a lot of management. Evap coolers don't operate like ACs, which recirculate indoor air over chilled coils. Instead, evap coolers are pushing dry, outdoor air through a wet membrane and into the house. So you actually need to leave a window open so the chilled air can move into the house and replace the warm air. If I was to run them both, I'd first crack some windows and then run the cooler. Once the house was as cold as possible, I'd then close the windows, turn off the cooler, and turn on the AC. You wouldn't really be controlling the humidity because the AC would just remove what water the evap cooler added to the air.
