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.
"We" as in multimillion dollar companies with 30 acre refrigeration centeres right? Since corps produce like what 70% of all emissions?
No. It’s like when toilets started getting smaller flushes. It doesn’t help on an individual basis, but as a whole it has an impact, even if it’s not a huge one.
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.
I'd this why it takes multiple flushes to do the job these days, when my toilet at home handles it in one? Oof
How often do you want to get food poisoning? That’s the trade off. Each degree increased is shifting the statistical curve on which the tail end is food poisoning occurrences.
If Google didn’t just lie to me 17MT of CO2 is the equivalent of taking 19 private jets out of service for one year. You’ll excuse me if I choose to lower my chance for food poisoning by making some rich dude fly commercial.
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.
The international standard for freezing food is -18C, about 0F, they are talking about increasing that by three degrees to about 3F or -15c, which would have no impact on likeliness of food poisoning. People should use private jets less as well but this seems like a change that could be made across an industry more easily. This isn't about people turning up their freezers at home but rather commercial food operations which accounts for a much larger portion of energy used.
This is the internet so take this with a grain of salt. I work in a life safety field and the last 50 years of research has been to shift the evaluation of safety from an arbitrary value for safety to a statistical basis - all in the name of efficiency (cost, material, environmental - pick you’re cause, they all have a voice). There is generally no perfectly safe condition, only a poly at which the number of standard deviations from the norm makes failure so unlikely as to be nearly impossible. We have classes of prevention and imposed conditions and there are under the intersection of (failure in prevention)x(exceptional imposed danger) are dead people, or at least loss of property.
Shifting the freezer set point is moving the prevention curve. The number may be small, but it’s still finite. The question the actuaries will ask is if the economic value of 19MT is worth an increase in probability for the sickness or death of X people. I’m merely arguing that the value, to me personally, is not sufficient.
TlDr: They think that it would be advisable to move the freezing storage temperature from the typical -18° to -15°.
My freezers are set by default at -20° though. I should probably change that.
As an indigenous Canadian that grew up poor, in about December, dad would transfer a large stock of our frozen food to the large capacity refrigerator next to wood pile outside our house. It wasn't powered by anything, the cold winter weather was enough to keep everything frozen for months.
I live in northern Ontario and when I think about that, I find it so strange that I live in a house that is kept warm to protect me from freezing temperatures outside while at the same time I spend a good amount of energy to have an appliance inside my warm house to keep my food frozen. You'd think in Canada someone would have figured out a way to harness that cold from outside for part of the year.

Look into the "cool cupboard" associated with David Holmgren, who talks about it in his book Retrosuburbia. IIRC it uses simple geothermal and natural convection to keep certain foods cool.
I live in a cold place and lately I've been taking water jugs outside to freeze, then bring them in once I go out in the morning. With them, the fridge hardly runs any more. I'd prefer something automatic like a cool cupboard for certain things and a well insulated fridge running straight on DC solar.
a change that would avoid 17 metric tons of greenhouse gasses
Uh, that's so obviously massively wrong. The headline seems correct though, it's about 17 MILLION metric tons.
Doesn't Mt mean magatons?
1 million tons are 1 megaton
