    yeah if you don’t have heating (wood, pellets, gas, fossil, electric, whatever) you can’t live in that climate. its, like, a thing.

    but its way easier to heat a thing and keep it warm than cool a thing.

        huh. I was just looking at air conditioners being really inefficient and it being really hard to keep a thing cool passively because all the stuff we do/have makes heat nowadays.

          It’s easy to passively cool things, as long as you’re okay getting them wet :)

            me? yes. my living space? less.

          On the other hand, ACs are heat pumps, which are generally efficient for transferring heat energy (both to warm and cool)

            heat pumps are extremely cool.

      The laws of thermodynamics disagree

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.
