There are 26 climate feedback loops that are ignored by most models.

Also feedback loops can interact with each other, in every possible combination. For example thawing permafrost releases methane which heats the climate, causing more wildfires which reduces rainfall, which heats the climate, soot from the fires falls on a glacier, etc etc

It's a lot.

Except that "there are 26 climate feedback loops that are ignored by most models" is a clear misrepresentation of what the article you linked to actually says, which is that this scientific team has identified 26 amplifying feedback loops, including some that the researchers say may not be fully accounted for in climate models.

"Some may not be fully accounted for" is a far cry from "ignored by most models". Spreading this type of false narrative on climate science only helps the people who use the "we don't know enough about the climate to take any action" excuse, please don't contribute to it!

So basically what you're saying is we're all majorly fucked and not in a good way. Might as we just get the money out of my retirement fund to have some fun with it while it lasts.

I am, but I also have a predilection for doomsday scenarios and zero climate science training. 🀑

And in the last year since this was published we've done fuckall.

I'm no scientist, but the cynic in me thinks that conventional models are made so moderate and safe as to support our current paradigm. Now that the climate has changed so far beyond our predictions, we're, oh, so surprised.

[-] WhatAmLemmy@lemmy.world 22 points 1 week ago

Nah. It's just extremely difficult to accurately model systems of such complexity and uncertainty. That's why weather reports can only do up to 2 weeks max. There definitely is fuckery from politicians and the status quo oligarchy in terms of what is passed and reported on, especially by orgs like the IPCC, but this type of acceleration falls within the wide variability of existing models; just not around the mean.

That's one of the main reasons why I think we're fucked. Scientists and their models don't know what they don't know, so some significant variables could be missed (e.g. feedback loops) β€” variables that ultimately make our modelling unrealistically, naively, optimistic.

We don't have perfect knowledge of the system we're modelling, of course the model falls short of reality.

I see it as the manifestation of Terence McKenna's idea of model theism. We create a model of the world and then worship it as a god.

Sounds like the climate change denial equivalent of the "atheism is a religion" nonsense that the stupidest Christian apologists keep spewing..

Yes, because the world is extremely complex. The sadder thing, is that even if we solved climate change tomorrow, we'd still have a few other ways for our planet to end, including destruction of soil habitat, loss of biodiversity, and literally dozens of pollutants like BPA and glyphosate, dyes for clothes, microplastics, heavy metals (including from tractor tires&exhaust right onto the fields we grow our food in)... And we have an outdated representative democracy that doesn't utilize our country's education or expertise. Frustrating. It's not the time of horses any more, we can fucking use technology now ya'll. We should be able to vote and discuss policy en masse from our homes/cell phones. We don't need representatives if we are literally our own representative in a true democracy.

Can we just shit out a lot of sulphur dioxide (anti greenhouse gas) into the atmosphere for 50 years whilst co2 emissions are halted?

[-] SlopppyEngineer@lemmy.world 2 points 1 week ago

Technically possible, but it'd be a few centuries before the excess CO2 is gone and you have to shit out sulphur. Unless you do massive CO2 cartridge too to reduce that time. And that will depends on cutting CO2 emissions to near zero what doesn't seem to happen anytime soon. Plus you'd have everyone screaming how much it costs the entire way.

When you catch a virus, your immune system induces a fever to kill the virus. In this case, we are the virus.

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.
