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.

Denmark has officially cancelled winter translated article. I don't like this timeline.

Yes, the line is going up. That's good, right? Shareholders keep telling me that the line must go up, and it looks like we're doing it! Good job, everyone.

May our descendants never forgive us.

If there are any.

Hottest year to date, so far.

Big fucked if true.

I looked it up the other day. We crossed 1c in 2015/2016. News stories at the time talked about how 1.5 might happen as early as 2035 if we don’t get our climate act together.
Yikes.

Grim milestone and barely a peep about it in popular discourse. Everyone needs to prepare personally for the consequences.

For one thing I'm not expecting food prices to level off for the rest of my life. Everything's just going to get more scarce and expensive. Is it possible common foods we enjoy now we may never have again at some point?

On a lighter note. I got a new winter jacket in 2019. Between covid and the rapid decline of cold winters I've barely worn it.

I see so many people thinking that this isn't going to be a problem for them because they are thinking of heaters and AC and also that they'll probably die while it's still livable.

But meanwhile they put kids on this world, who will call our generations the worst people to have ever existed.

Despite what capitalism would have you believe, humans are part of nature. With the same effort that has allowed us to destroy nature faster than any other species, we can maintain or restore balance better than any other species. It makes as much sense to argue against the next generation of humans to "restore the ecosystem" as it makes sense to argue against the next generation of bees.

Let them call us, those born in the 20th century, the worst people to have ever existed. It's not far from the truth. But why let that stop us from doing the right thing: giving birth to them so they can fix this mess for future generations or die trying? Why let our shame deny the ecosystem the best chance at recovery?

Because living in a world with extreme weather events where you can't leave your house for weeks because of heat waves and never before seen storms, and possibly damage to your home(this has already happened where I live), where a home garden will die to heat waves, with constant shortages of food and water, is not a life I'd wish on my enemy, much less someone I love.

We are already starting to see more extreme heat waves and weather, we know it's happening, and we're drilling for more oil than ever, so the chances the next generation will suddenly start making big changes when the past two have done worse than nothing while being fully informed seems extremely unlikely to me. I'm pretty optimistic on most everything, but there is not a single sign pointing to this being resolved by humans within the next 100 years, if ever.

We at least didn't have kids, and I'll probably accidentally drink myself to death anyway.

We did it guys 🥳

Sitting here in a beautiful sunny day, people can be forgiven for thinking its not a big deal.

Until you realise how much energy it takes to raise the temperature of the ocean and land by 1.5. And then that all that energy goes into every weather event forever until we reverse it.

55 degrees F in Massachusetts a week before Christmas. I was driving with my windows down. I got nuthin else. What the shit, man.

[–] [email protected] 4 points 5 days ago* (last edited 4 days ago) (1 children)

It’s been twenty degrees F (11C) above average in Arizona this week. Should be frigid with snow on the ground (in the mountains) yet I was riding my bike with a t-shirt this week.

[–] [email protected] 5 points 4 days ago (3 children)

OK, I looked it up. Average from 1979 to 1999 for me on December 17th was 29.1 degrees F.

The shape of that curve scares me. I just hope it's a sigmoid curve, not an exponential.

[–] [email protected] 8 points 5 days ago

Every collapse seems to trigger 12 others, further compounding things at an insane rate

[–] [email protected] 21 points 5 days ago (2 children)

True exponentials are rare in nature. Things can look exponential in the short term but are really logistic.

Look at it this way: if the atmosphere gets hot enough it’ll boil off into space and then the earth will cool back down again due to the loss of greenhouse effect.

I just binged la Palma on Netflix. Here we go.

And with it, another group of mitigation advocates become doomsday acceptors in the scientific community.

[–] [email protected] 27 points 5 days ago

Yeah, sadly not a suprise
