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.

A growing body of scientific evidence now suggests that, due to rapidly increasing greenhouse gas emission levels in the atmosphere, the world is on track to overshoot the Paris Agreement’s 1.5C target within the next three years, pushing the planet beyond a critical threshold faster than previously feared.

The dire warning comes from the most up-to-date assessment of the state of global warming, led by a group of international researchers and published in Earth System Science Data earlier this month. The report was signed by over 60 scientists across 17 countries.

IMO the imminent climate tipping point was when the ice caps started releasing massive amounts of methane into the atmosphere and the oceans began acidifying. Every since that' it's just been damage control, minimizing the casualties of hundreds of millions if not billions of effected people as the catastrophes are assured to get worse.

Your comment reminded me of a recent article from Carbon Brief:

Experts: Which climate tipping point is the most concerning?

People won't care until they are directly impacted. It won't be enough if their nan dies of a heatstroke. They have to have a heatstroke, have an inundated house, lose their belongings in a forest fire, or switch careers because there aren't any more bees in their area. And even then, once they solve their own problem (if they can), they will forget about everybody else.

At this point there could be car tires melting in the heat and storm floods burying whole cities. People would still be bleating about "leftist ecoterrorists" and "gubermint takes away muh freedumbs"

Every day I feel my anxiety building as we get closer to ocean current collapse. People have no clue how close we are to ‘irreparably fucked.’

My solution has been to spend time getting my gear in order, learning practical skills, and perhaps developing a spiritual practice such as meditation.

You should include building community. Regardless of the narrative driven by the cult of individualism, no man is an island.

I've tried and tried and tried, turns out the vast majority of people, including ones who theoretically would be into this, are beat down & atomized to the point where their primary goal in life is to not have to adjust their personal trajectory in any way, shape, or form, until they absolutely fucking have to on pain of death. 🤷

and then the ones who are actually into realistic prepping and want to work with others are batshit fucking crazy, but I think that might have something to do with my sample size of n=1 after trying to collaborate on shit like this for over a decade.

edit: it also doesn't help that I'm autistic with a literal night watchman / jumpy cat phenotype, and have been unable to access sufficient solitude to function for nearly a decade, so I myself am sufficiently beat down & atomized that developing community comes lower in my priority queue than getting access to any precious scrap of solitude I can, in a constant losing battle to meet my basic sensory needs 🤷

Trump this, capitalism that, he said, she said, birthrates, coverups. None of it matters, we'll all be starving to death in 20-30 years.

I thought we passed 1.5C last year?

[–] Doc_Crankenstein@slrpnk.net 5 points 2 days ago

At this point it is just shifting goalposts.

No one wants to admit that humanity is fucked because then all efforts (what little efforts those may be) to calm the incoming storm will come to a halt.

Plus the powers that be are intentionally trying to prevent mass panic by sanitizing the message as still being hopeful so that people continue to engage with their respective economies. Most people only go to work because they think they are working towards some type of future. Tell them there is none and they no longer will go into their jobs to generate revenue for the oligarchy to profit from. The oligarchy doesn't want that.

IIRC, it has to be passed for 3 years in succession.

Hell yeah, I was right to invest in Swedish summer resorts!

The AMOC slowdown is likely to make it rather nippy over there. Models predicting collapse of the AMOC seem to converge on 2050 as a likely start, with lower-bound estimates converging on 2025

Yes, my source is a youtube video. They include a good list of references in their description.

Damnit. Thank you for bringing this to my attention.
