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.

Are people just not aware that most natural gas appliances can be run with propane and not just the natural gas that utilities might provide? Usually just requires adjustment of the flow-rates on the appliance and fuel supply line. I forget which is which, but natural gas and propane run at two slightly different pressures, so if you don't adjust for that during the changeover, it won't burn as efficiently.

I mention this more as a "what would I do if I was told I had to sign up for the natural gas utility". Of course, this doesn't take into account that if you have natural gas coming to the house, you probably use that as your primary heatsource as well. So that's a consideration. In terms of kitchen appliances though, the info might be useful to someone.

It's usually more expensive to burn propane than natural gas.

Higher price per unit, but propane burns 2-2.5x more efficiently. So what might be more beneficial to one person or another most likely depends on other factors, such as region and availability.

Almost nobody ends up using propane when they've got piped gas available. Which says that it's not a great choice.

[–] TalesOfTrees@sh.itjust.works 1 points 7 months ago (1 children)

Or it just confirms developers being in cahoots, and consumers being unaware that they have choices, even when it doesn't seem like it. Hopefully you're not interpreting this as me trying to argue with you, as my intention is more of a "hey, by the way here's something" rather than an attempt to convince anyone of anything.

in the case of apartments the consumers don't have a choice, which is why new gas line bans are so important

Or just live somewhere else and don’t ruin shit for the rest of us?

My city has natural gas piping and there are still propane tanks all around.

[–] silence7@slrpnk.net 2 points 7 months ago (1 children)

Very unusual if that's the case.

[–] NoIWontPickAName@kbin.earth 0 points 7 months ago (1 children)

I never really thought about it until this discussion. I’m used to propane tanks for people who live in the country

[–] silence7@slrpnk.net 2 points 7 months ago (1 children)

Exactly. There are propane tanks in areas where there aren't fixed pipes to deliver natural gas. Once those are installed, people switch to the cheaper option.

This is a big deal because right now heat pumps are almost always cheaper than propane, but not cheaper than natural gas.

[–] NoIWontPickAName@kbin.earth 0 points 7 months ago (1 children)

No I meant there are still houses here that use propane, I was looking at one on Monday, smack dab in the middle of town

[–] silence7@slrpnk.net 1 points 7 months ago

All I can say is that this is very uncommon. Either that location never got a natural gas hookup, or something unusual is happening.
