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.

The analysis makes sense, more energy for cooling in sumer - less energy for heating in winter = more energy usage overall in Texas. It would be interesting to see it repeated in colder locations like Northern Europe or Canada to see what the result is.

I dont think you could find a European country, especially a northern European country, that has A/C equivalent to Texas for a comparison

Where I live in the UK you normally only see a few days where it pushes around 30°c or so. AC doesn't really seem worth bothering with due to the cost of it but some kind of improvised cooling would be nice. I was thinking of making an arse cooler with a hose pipe, pump and bucket of water with ice in it.

Well no, that was what I meant, I would like to see whether rising temperatures lead to increased energy demands in other climates. Or if it would actually lead to reduced demands due to milder winters and less AC usage.

Its definitely a trend I see a lot in renewable energy circles, study how things are in southern California or Texas and then draw conclusions and policy prescriptions from that without considering other climates.

In Texas, poor management of the grid and privatization of energy utilities is causing rate inflation more than climate change.

Don’t forget Bitcoin mining (and especially that they pay them some absurd amount to not mine when at peak load.) That presumably all gets passed on to consumers.

I'm going to be honest, I only skimmed part of the article. The graph with 1989s data vs 2023 data made me wonder... Did they take population into consideration? I'd imagine yes, but again, I did not read. The concept makes sense in theory and seems to be correct in practice.

Texas lol. Like anyone cares

[–] [email protected] 6 points 22 hours ago (1 children)

Considering the sweeping loss of maga in Texas, I'm thinking some Texans are starting to care, which is good to see.

Yeah, but it’s like too little too late for me. I really wish they would just split off and do their own embarrassing thing. In fact, please take the rest of the confederate states.

[–] [email protected] 2 points 13 hours ago

Oh its definitely the bed they made.

I'll take whatever positives I can get though
