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.

Pollution and home safety aside. I found it nice to pinpoint my desired heat. It works so fast and accurate that I got consistent pancakes like i never used to before.

That's pretty cool. Can they heat a pan as fast as a gas stove? One of the major inconveniences with an electric stove is having to wait for the burner to heat up, before you can wait for your pan to heat up. I've had resistive stoves for decades now, and they're not very good IMO. But I've never had an induction stove. I've really missed the gas stove we had when I was a kid.

Simple answer: yes, induction hobs are fast, maybe even faster than gas.

That's really cool.

Back on gas after having induction (moved).

I also grew up on resistive and was as skeptical as you are. Now, I dream about upgrading to induction again once we are able to reno the kitchen. For example, boiling water on induction is more than twice as fast as gas and the temp adjustment goes so quick that even cooking eggs is a breeze.

Yeah, when I fry eggs the pan heats up to temperature in literally seconds - not a half a minute, but like 5 to 10 seconds.

Resistive stoves are slow because heat has to move from the coils, to the air above the coils, to the glass top, to the pan, to the food.

Gas stoves are fast because heat can move from the flame, to the pan, to the food.

Induction cooktops are the fastest because heat gets to move directly from the pan, to the food.

Induction uses magnetic fields to directly impart energy into the metal of your pan. Magnetic fields move energy at the speed of light. That's faster than gas can move heat. Which means your pan warms up quicker.

You can imagine an induction stove to work similarly to a resistive stove, only with your pan/pot being the resistive element. The slow part of resistive stoves is the heat transfer from the element to the cookware, so you can imagine how quickly an inductive stove heats that thing up!

it's noticeably faster than a gas stove. plus the neat thing is it's not giving you and your family cancer!
