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.

According to several other data sets, 2023 reached 1.5C too. Dramatic record low Arctic sea ice volume throughout the year, and current, including at north pole is ominous for north pole being ice free in next 2 summers.

I feel like we're in a movie where we are all bickering for petty reasons (namely wars and political polarisation), while in the background-- away from our sight and out of mind-- an abstract, cosmic horror is progressively happening. Preparing to kill us all.

You should watch Don't Look Up

I watched Don't Look Up long ago. But in our real life case, I imagine somehow a far more sinister yet indescribable horrific dark entity conspiring to kill humanity.

I haven't even read any of Lovecraft's work, and yet here I am imagining an indescribable horror lol.

I think now that the real horror is humanity committing a slow collective suicide. We're all trapped by our own ego that we neglect the greater problem.

Congrats, everyone! We finally did it! And way ahead of schedule! Take that, scientists! They said we couldn’t do it before 2050. They warned us! They scolded us! But look at us now! Eat it, nerds!

sigh

This is fucking ridiculous.

I'm just sad I'll never have another snow filled winter living here

[–] [email protected] 7 points 4 days ago (1 children)

Don't despair! If we keep at it for long enough, we might destroy the AMOC (Atlantic Current), which might mean much lower temperature in Europe and North America, and much higher temperatures in the equator.

So you might not see snow in winter, but you'll probably get ice sheets in New York and Paris

[–] [email protected] 2 points 4 days ago

Haven't Paris and new york have it hard enough?

So about when can we expect the next ice age?

[–] [email protected] 6 points 4 days ago

We're in the ice age, it's supposed to be cold right now. So... Around 100,000 years after humanity either dies out or becomes subterranean.

Don't worry, cheaper solar panels, electric cars and entrepreneurs will save humanity. And by humanity I mean a specific share of the world's developed nations. Discourse on this frustrates me to an unhealthy degree.

If you promote techno-fetishism laden, borderline tech-bro driven or shitass bill gates financed media, please reply so I may wish upon your remaining bloodline an everlasting mildly inconvenient curse.

And if you like Kurzgesagt tech videos, please reply so I may respectfully call you a fucking donkey.

[–] [email protected] 2 points 4 days ago (1 children)

I'm frustrated by the discourse too but I'm not sure it's for the same reasons as you.

What frustrates me is we never seem to discuss goals and why we have those goals.

Is the goal to keep the average temperature of earth as low as possible for as long as possible?

Is it to minimize the impact and costs for humans?

What exactly are we aiming for, and why?

What is your frustration with the discourse?

[–] [email protected] 2 points 4 days ago

Is the goal to keep the average temperature of earth as low as possible for as long as possible?

Human sustainability requires having those goals. Protecting oligarch wealth is within oligarch corruption power, and human prosperity is a sacrifice they are willing to make. Genocide of the uppity disenfranchised as a final solution seems natural today., as the path forward.

What's that about kurzgesagt?

I often found good citations/ research evidence linked to their claims (on climate change)

[–] [email protected] 2 points 4 days ago

They list their sources! Their content tends to be pretty well done, even if not perfect.

[–] [email protected] 2 points 4 days ago (1 children)

They repeat whatever their donors claim without any checking on their part. Sometimes this lines up with science, sometimes it's just propaganda.

[–] [email protected] 8 points 4 days ago

Any example videos that are propoganda?

I'd like to scrutinize one so I can fact check better in the future. I mainly check the citations in the links.

[–] [email protected] 6 points 4 days ago

Line go up so line can go up

Bingo!!!

I had this on my 2024 bingo card.

God I hope I'm wrong about 2025 BOE.

[–] [email protected] 20 points 5 days ago (1 children)

And so far, what have we done?

Pretty much nothing. We've done a lot of pretending with "let's recycle plastics", which them just get dumped anyway because fuck you, that's why.

We're slowly slowly moving to electrical cars instead of pushing hard for bicycles and public transportation. Profits over anything else!

We've implemented.next day deliveries, because THAT is important. Fuck your winter

The US just choose a climate change denier who put a guy in charge of the EPA that can't stop talk about pushing businesses and economy and oil.

The world is lead by narcissistic psychopaths and everyone just lets them.

I wanted to see that compared with global energy demand

[–] [email protected] 4 points 4 days ago

Yeah, this graph shows it all. The previous looks impressive, this one looks depressing
