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.

I know I’m preaching to the choir but we need to do more and yesterday.

[–] Deceptichum@sh.itjust.works 30 points 3 months ago (1 children)

Elect me and I’ll set a goal by 2040 that we will consider a policy to begin looking at doing more.

That's crazy talk! Just mentioning that made my shares in FuckThisPlanetOilForLife drop by 0.0000001 percent! You'll ruin the economy! Think of the share holders and the rich!

[–] henfredemars@infosec.pub 2 points 3 months ago

We are so fucked. I focus on enjoying the time we have.

I'm just listening to assholes vroom-vrooming up and down the nearby thoroughfare day and night. Each and every one is accelerating the problems for everyone, and they can't give a fuck.

I see nascar and f1 and think: what fucking planet is this being broadcast from?

India, pakistan and mexico are literally cooking. this week we're predicting heat waves all over the US and Canada even.

How many dead people from heat will it take before someone says "Hey, you know, we could cut out a lot of emissions just by stopping the 'for funs' bullshit"?

I can offer you worse. Rolling coal is legal here. It’s considered cool to put out lots of black exhaust.

[–] mojofrododojo@lemmy.world 4 points 3 months ago (1 children)

Rolling coal is legal here.

I live in the states, it doesn't seem to be illegal here. Do we suffer from the same assholes?

[–] henfredemars@infosec.pub 3 points 3 months ago* (last edited 3 months ago) (1 children)

To be clear, it’s legal and common especially because we don’t have any emissions standards enforcement. In my state, there is no test whatsoever, and even if you’re blatantly belching clouds of smoke it is 100% tolerated. It’s a bizarre badge of honor among some hyper conservative residents to pollute as much as possible.

I think operating a motor vehicle should entail a certain degree of responsibility including environmental responsibility.

yup. and consequences for those who won't. world's literally cooking guys, every bit will help, and every vroom vroom revving their fucking engines is hurting. time to be adults and put the toxic toys away.

roomba f1.

we're fixing this shit!

Why does this seem like the part of an exponential growth curve where it starts to go asymptotic? Like maybe I'm crazy, but this seems real real bad.

[–] coaxil@lemm.ee 27 points 3 months ago

Not crazy, it is real real bad.

[–] tlf@feddit.de 22 points 3 months ago (1 children)

This representation looks pretty

[–] AnonStoleMyPants@sopuli.xyz 6 points 3 months ago

First thing I noticed too! Gorgeous graph.

[–] Five@slrpnk.net 5 points 3 months ago

Thanks, added to the post-text.

[–] sep@lemmy.world 5 points 3 months ago

February looks like it is gunning for someone... what a worryingly consistent increase.

[–] match@pawb.social 4 points 3 months ago

This is a great image but every month looks like Saddam Hussein hiding underground

[–] otto_von@lemmy.world 4 points 3 months ago (1 children)

We had a tool for these blobs, it was called histogram. Looks pretty though.

[–] DrBob@lemmy.ca 7 points 3 months ago (1 children)

You are missing the subtleties of this presentation that goes well beyond a histogram. This is a very nice layout that shows variability by month and decade.

[–] otto_von@lemmy.world 1 points 3 months ago

Okay right, the colour code is extra.
