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.

Guys it's simple. Just ~~don't look up~~ stop measuring the temperature.

That's how we've beaten climate change in Russia πŸ’ͺπŸ’ͺπŸ’ͺπŸ’ͺ

And in ~~little Russia~~ Florida

Alarms, sure. Confounds?

Confounds? defined - verb - cause surprise or confusion in (someone), especially by acting against their expectations. "the inflation figure confounded economic analysts"

IS THERE ANY FUCKING DOUBT AT THIS POINT?

[–] ChairmanMeow@programming.dev 17 points 7 months ago (2 children)

It's confounding because Earth is heating up significantly faster than is currently explained by our climate models.

[–] mojofrododojo@lemmy.world 17 points 7 months ago (1 children)

1.5c was in the rear view window when we decided 1.5c should be the ceiling. we've passed a tipping point. I think the vast majority of climatologists aren't confounded by the results, simply determined not to be accused of doomerism.

watch, when the shit really hits the fan, conservatives will find a way to blame them for not warning enough.

Everybody laughs until the seasons are no longer reliable enough to grow wheat, corn, or rice, and then suddenly 7.5 billion people starve to death over a two year period.

I'm worried this summer we'll see massive crop failures and significant deaths from heat. It was 38c in Delhi today - we're nowhere near the hottest part of the year. It's going to be brutal.

Almost like the climate models are sponsored by big oil to make them seem less dire and the original models are more accurate with their warming predictions

[–] ChairmanMeow@programming.dev 2 points 7 months ago

We're warming faster than every climate model, that's the point. It's going faster than the most pessimistic model right now, which is confounding. We can explain most of the warming, but there's a bit that we can't attribute to any known cause/.mechanism just yet.

Among scientists there wasn't any significant doubt twenty years ago. It was just spin doctors trying to pretend otherwise.

[–] whoisearth@lemmy.ca 7 points 7 months ago* (last edited 7 months ago)

More nefarious than that IMHO. The science community works on consensus.

So when we say temperature will rise by 2.5 degrees and we are fucked That's the number they all agreed on.

99% of scientists may agree that a 1 degree rise means we are fucked. The 1% says 3 degrees. So if big business or shit government gets to that 1% they can control the narrative around what is socialized.

I'm a child of the 70's. Scientists have been ringing the warning bell for decades. Look at how ocean acidification is swept under the rug in all climate discussions. Scientists know it's a huge problem and has been since at least the 80's but do ALL scientists agree we are fucked?

If I was a scientist I'd be so damn jaded at the state of the world.

At least we can all be happy we are helping people get rich. Thats what is important after all.

[–] lemat_87@slrpnk.net 2 points 7 months ago

Among scientists and on slrpnk - no surprise. But the society is sadly not concerned enough. I feel no one does a fuck.

[–] itsonlygeorge@reddthat.com 18 points 7 months ago (2 children)

It’s not like we didn’t know this for over 50 years. Why act surprised now? The oil companies had studies for decades on global warming, climate change, etc. Scientist have been talking about it for just as long and no one listened.

[–] lemat_87@slrpnk.net 1 points 7 months ago

That's very true. I think that such articles are important anyway to remind wider audience about the problem.

I don't see the issue. Climate isn't an engine or whatever. It's a complex system that we don't know how it fully works. Human introduced and introduces changes in this system. We barely understand all the effects these changes have as we don't know how it fully works.

Of course, we can only assume the consequences.

[–] towerful@programming.dev 8 points 7 months ago (1 children)

While i agree, unfortunately these models (hopefully) drive politics.
Politicians will do the minimum they can get away with. Thats both human nature and capitalism.
If the models undershoot (climate change accelerates faster than scientists predict), the world is fucked.
If the models overshoot (panic etc, and it ends up being a nothingburger), people will stop trusting models.
If the models are spot on, action is taken, and everything is fine... Everyone doubts the models and the hype - despite the fact the threat was understood, acted on and fixed, and a catastrophy averted (think y2k)

I think we are pretty fucked, tbh.

I think that human ingenuity still has a chance. We need to stop letting psychopaths lead, though.
