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.

While I don't agree they're better, a key feature over conventional electric (and one of the main benefits of gas) is that the stove surface doesn't inherently retain heat. They get hot, but only because the pan is hot. When you turn down the heat, it's immediate, like a gas stove.
I don't know about how fast they can heat; gas can output a ridiculous amount of BTUs, but at 240v I wouldn't be surprised.
Have to keep efficiency in mind as well. Practically all of the heat produced by induction goes directly into the pan bottom. With gas, quite a bit of the heat doesn't end up in the pan.
In my experience, induction on high settings heats much faster than gas. Sometimes faster than is desirable actually. A pot of water will boil at the bottom when the top is only somewhat warm.
I don't know about the US, but in Germany it's common that the individual or two plates of the induction stoves have their own 380V cable and breaker.
North America has one 240v plug for the whole appliance, 120v is what's used for regular electric items.
The US often has some appliances wired for 240V; I assume stovetops are, but IDK. Large appliances have their own breakers. I was told that if we wanted to install a built-in microwave, it'd require a new, dedicated wire and breaker.
A lot of places have code requirements that the microwave have its own breaker even though they're almost all 120v; it's because they use almost all the amps on the 120v circuit so you tend to trip the breaker if you have anything else big going on, like an electric kettle or a vacuum cleaner.
Yeah, in the US for an electric range you're looking at a single 240 volt split phase 30 amp circuit.
