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

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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
Yes, that would be better for people who weren't already doing what I'm doing.
Oddly enough, I've actually also got a RTLSDR dongle lying around. The only thing I don't have is an outdoor temperature sensor, but instead of getting one I'll stick with my current plan and save a weather station and/or permanent/continuous freezer monitoring for a future project.
Yup, I was suggesting it as an additional option where you can leave your heatermeter permanently installed on your smoker, and also monitor your freezer with minimal effort. Running rtl_433 is like a 5 minute project, and even an original Pi can run it with cycles to spare.
FWIW I found the best way to improve freezer energy performance is to drop your ambient temperature. This improves the COP and cuts cycle time more dramatically than changing the cold side setpoint (assuming you don't have the freezer really cranked to near the limits of the compressor).
My freezer is in the coldest part of my house, mostly by coincidence as that's the part nobody really lives in, with the laundry and such. It's zoned off to mostly just be kept above freezing by passive heat.
