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.

We’re over-freezing our food. Turning up the temperature slightly could avoid 17 Mt of CO2 (www.anthropocenemagazine.org)

“This temperature corresponds to 0 degrees Fahrenheit, so it was “probably a round, easy number to remember”

That’s what Allouche and team will be working on next, as they build their research summary into a full report, to be published in September 2024. “These findings give good reasons for ‘3 degrees of change’ to be further explored,” Allouche says.

Yep this is why I place a thermometer in the warmest part of the fridge (upper door, near the butter tray) and make sure that part never goes above 36-37°F. The back of the fridge hangs out in the low 30s – enough to freeze – but my food lasts a lot longer before going moldy. And there's the added bonus that it helps keep the kitchen warmer in the winter, too.
