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.

curious how its always us who end up footing this kind of bill, never the big refrigeration centers and such.

They're probably already running at the optimum temperature. Power is their main input cost, and they're strongly motivated to minimize it. Meanwhile the average household freezer is set to... Um... how about "7". That sounds pretty cold to me, yeah?

You wouldn't believe how much research has gone into studying things like the optimum way to store potatoes.

mine is usually set to minimum, believe it or not people have power bills too, and at the end of the day it gets priority over whatever the optimum temperatures are. spoiling food has an indirect hard to quantify impact, but power bills come every month with a big fat number on it.

the difference is most of them wouldn't be making as much money, but most of us might not be making rent.

at the end of the day they don't need to convince me if they really want to sell me shoddier fridges, because they are the ones calling those shots. turns out its a moot point anyway sadly.

IDK maybe something to do with the fact that they are providing a service that only runs because it's popular and used?

For what it's worth there is tons of regulation on this shit. It just doesn't say what you want it to say. Commercial energy use commonly followed a completely different rate structure.
