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.

Most Americans want to electrify their homes — if they can keep their gas stoves (grist.org)

How many tons of co2/methane are emitted annually from residential ovens and ranges?

I feel like this number is small and am curious if anyone has chased this rabbit.

Electrifying everything but the gas stove means keeping the entire gas distribution system, which leaks like a sieve.

Well why are they building them out of sieves?

Propane tanks too? Or so you mean the methane pipes?

The article I linked is about methane but, as someone who is on propane, I can pretty much guarantee it's not much better. I don't know if you've ever been around a propane fill-up, but the connection/disconnect process breaks of the odorant - it definitely has a loss on every transfer.

The only good news is the emissions factor for propane is much lower than methane

I have a propane tank for my range. I've only had it for 3 years and haven't needed to fill it yet.

I cut our gas line 2 years ago from our house! Feels good. Also didn't want to have to invest in a seismic shut off gas valve.

And the heat pump gives us air conditioning, which is a win-win.
