Climate - truthful information about climate, related activism and politics.

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.

If induction cooktops would tell you their pulse width modulation I’d be so happy.

What does that determine when shopping?

Short frequent pulses mean cooking is smooth at the lowest power settings when using a light pot

[–] Semi_Hemi_Demigod@lemmy.world 8 points 2 days ago (2 children)

Yep. And long slow pulses will burn my marinara.

is this a sex thing

[–] Semi_Hemi_Demigod@lemmy.world 5 points 2 days ago

Only if you braise some beef short ribs in it with some red wine. Then you’re gonna get some sex.

Or at least that’s how it worked for me last time.

I've had great success using fairly thick heavy pots for sauces.. Though maybe I have a stove with a shorter pulse interval than yours

[–] Semi_Hemi_Demigod@lemmy.world 3 points 2 days ago (1 children)

I’ve just got an induction hot plate which has a 1 Hz pulse width modulation. (Yes, you read that right.)

I love it for large pots of stock or getting a pan superheated for searing but anything low and slow is going to get ruined.

So while I’m not opposed to induction - though I’d need to rewire my house for it - I’m not going to buy one without a test drive.

(Though I wonder if I could mitigate this with a thick slab of steel as a thermal regulator.)

"Can I have the technical specifications for my, uh, stove?" Not a legitimate question i was expecting...

[–] Eshrekshion@piefed.social 2 points 2 days ago

Oh yes. The flour test or water bubbles. Just ordered a GE one we’ll see how it does
