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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Positive feedback loops, how do they work?
We've known about this for decades. An example: heating causes permafrost to melt releasing CO2 and methane, which cause more heat to be trapped, which melts more permafrost, which releases more green house gasses, etc.
Positive feedback loops tend to be very unstable, and can lead to runaway situations.
Can't wait for all those ice caps to go away and stop reflecting all the heat that they do reflect being white. It'll just add to it.
And when the last ice is gone we will finally have revenge for the Titanic
Hey I found time to laugh in between my doomsday crying.
Thanks. :)
Not if blackhat has anything to say about it: https://xkcd.com/2829/
Looks like it might be a good idea to paint sections of buildings black and white, colour coded for heating lol
We actually paint the top of some helicopters to make the ride cooler for everyone inside.
Worse, when that influx of arctic water shuts down the North Atlantic current and others that cycle heat and cold throughout the world. That will be very bad for quite a lot of us.
Can't wait until we turn the planet into Venus 2.0
Ive read somewhere that living in the clouds is in theory still possible. :)
I'd like to live on the ground with the grass and the trees, thanks
"go touch grass" will be the new "kill yourself" in a century 😂
Sorry, best I can do is underground bunker
The article goes out of its way to claim this isn't the case. Theres a line that says something like there is no extra heat in the pipeline.
I followed the links in that quote:
Neither addresses tipping points. They seem to talk about something else entirely, like wether a model assumes constant atmospheric concentration, or constant emissions, that kind of difference.
Ah, i see what you are saying now, sorry
There's so much wrong with comments starting with "So you ...".
Yes, I'm not a climate scientist. I don't have the time and energy to read all the relevant papers, nor do I need to do so to participate in the discussion on Lemmy. Sometimes I do, but I'm not obliged to, and you're not in a position to judge.
It's great though that you read the paper. Can you support your claim with quotes from it? After all, I don't trust random dudes.
Nah, that's you. Oh, ok. I did not understand you wanted to point out that. This is confusing. Maybe you misunderstood my initial comment.
I'm not agreeing with the quote from the article, but speaking against it.
People are really bad at conceptualizing exponential change from feedback. Our brains expect incremental change. I think that's one of the reasons people can't know accept what is happening.
"I know things are changing, but it's only a bit each day, and it can go like that for years and it won't be that bad."
