I will not buy an induction stove unless I know why it’s pulse width modulation is.

PWM is vital; I can melt chocolate on my stove today but “low” often is 100% power at 90% off 10% on and burns food. Also making sure the boards and chips are hefty enough. I don’t trust Samsung and LG to lay enough of a trace on the board or use a sufficiently large heatsink on the switching circuitry that it’s not going to melt through when I boil water daily. I don’t recall details but last time I was looking into it, even some higher end brands had failure rates after 5-10 years (or sooner if the “power boost” or whatever was used because they cheaped out. My gas stove will survive the apocalypse, but whether it survives the Operation Epic Fail is another thing.

Damn, I didn’t even think that these are also made as cheaply as possible and in a way that makes them unrepairable. It’s a lot like electric cars: I get that they’re better but I don’t trust any company to make one that doesn’t do something shitty.

It’s a lot like electric cars: I get that they’re better but I don’t trust any company to make one that doesn’t do something shitty. This is irrational past a certain point however, there is no reason non-electric cars won’t be programmed to do shitty things to? This is Xenophobia wrapped up in our emotions around cars, there is little evidence that Electric Vehicles are more vulnerable to being hacked than other kinds of cars, the reason everyone is nervous about this is that “western” car makers are being left in the dust because of their own stupid choices and everyone feels anxious about it. This is how it manifests, a general mistrust in electric vehicles we intuitively seem to have that is a mirage obscuring feelings of insecurity about our own societies.

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.
