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.

That is a wonderful visualisation. Thank you for sharing it.

[–] thejevans@lemmy.ml 15 points 4 days ago

Yeah, this is honestly god tier

[–] nick@midwest.social 14 points 3 days ago

Someone download this before they memoryhole it

Seems like it really is spiralling out of control

[–] Etterra@discuss.online 3 points 2 days ago

Death spirals go out now. Neat. At least we'll go extinct with some cool graphics.

What happened in the 80s? Seems the temps were all sorta within a pretty standard deviation until then.

Who left their heater running?

That's hilarious. I use the phrase "I blame Reagan" all the time. Sorta like how people used to blame everything on Obama as a joke?

Reagan really fucked everything up for this country and planet for a loooong time didn't he.

Fucking Reagan.

[–] hOrni@lemmy.world 12 points 3 days ago (1 children)

That's why I feel for Trump. Dude just wants to be remembered. He knows he won't be the greatest president. So he tries a different angle. He wants to be forever remembered as The Worst President In The History Of The US. Alas, there's Reagan.

[–] Majorllama@lemmy.world 4 points 3 days ago

Time will tell which one has longer lasting worse effects. There is definitely some recently bias with Trump but I feel like Reagan damage has been long and slow.

Iirc, if you're 60 today, around 75% of human CO2e emissions were created during your life time. The number may be a little off, but the point is: since emissions have steadily increased, it's very likely that the majority of emissions were emitted during your life time. Which also explains why shit is getting crazier very right now, as emissions are on a level never seen before and still rising.

[–] EddoWagt@feddit.nl 6 points 3 days ago

But the rising is slowing down! Yes we're still emitting more and more everyday, we're atleast emitting less more

That's when dad's started yelling a little bit less at kids leaving the doors open in the winter. It's really gotten out of control since then. Between this and light switches being left on with a thorough shouting, modern Dads are pretty much to blame and not spanking children probably has something to do with it too.

Global temperature seems to be (put on sunglasses) spiraling out of control.

„Climate has always been changing”

[–] Corgana@startrek.website 22 points 3 days ago (1 children)

This is still the best at capturing it, imo: https://xkcd.com/1732/

[–] riodoro1@lemmy.world 4 points 3 days ago

I love it too

[–] OR3X@lemm.ee 8 points 4 days ago

See, I used to remember being able to go outside and play during the summer when I was a kid. Now days it seems like of you dare go outside in the summer you'll be a puddle of sweat within 30mins.

[–] phoenixz@lemmy.ca 6 points 3 days ago (1 children)

I don't want to watch this

Not anymore

I've carefully watched this for decades

I've urged everyone to take action

I've carefully separated my garbage

For decades

And nobody cared, nobody cares

Then comes in trump who just waltzes over everything and aims course straight for hell

Let the world burn, I don't want to one about it anymore, I'm done, I'm burned out, nobody who can make a difference gives a shit.

Unless tomorrow all the rich and powerful in the entire world disappear, nothing will change, so I'm just going to sit here, enjoy the sunset while we still have fresh water and food and I fully expect most or all of humanity to be gone within 50 years

[–] stickly@lemmy.world 4 points 3 days ago* (last edited 3 days ago)

Why not go out doing something exciting at least?

It's easy to make statements like that before desperation sets in. Starving is an awful way to die, death after nuclear fallout is excruciating and slow, you won't enjoy any sunsets when the smoke from burning cities fills up the sky.

50 years from now when you're freezing in a cold muddy ditch, you'll be wishing you died a martyr taking the 1/1e10000 chance to fix it.

Edit: I'm legally required to clarify that martyrdom can result from non-violent acts 🙂

[–] WhatSay@slrpnk.net 5 points 4 days ago

We already hit the +1.5 the last couple years, and it's growing from there

[–] Chronographs@lemmy.zip 2 points 4 days ago (1 children)

I wonder how long until this gets taken down

[–] Blackmist@feddit.uk 3 points 3 days ago

You mean until NASA gets shut down by a man with a vested interest in the space sector?
