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.

But we’re out of ideas!

Fine. I'll finally give up plastic straws.

Breaking news, global warming stopped.

Plastic straws are not the problem. If we use petroleum to make plastic that carbon is effectively captured in that straw. It can create pollution for sure but it's not adding greenhouse gases to the atmosphere.

Nothing individually is “the” problem. We have a wide variety of problems to choose from.

That's not how anything works!?!?! It was 100% captured in the petroleum, even if the process of petroleum->plastic straw is 99% efficient you're adding greenhouse gasses to the atmosphere.

And it's nowhere near that efficient! Cracking alone is 65-86% efficient with probably a minimum of 2 other processing steps of similar efficiency (SWAG of 27-64% final efficiency). The waste isn't all greenhouse gasses, but a good amount is...

The production process for paper straws also produces greenhouse gases. Making paper also used up a tree somewhere. So this notion that switching from plastic straws solves the problem is false. Its impact is negligible.

It's virtue signalling by fast food companies who should be focusing on switching to using green energy and using electric transport rather than making us all suffer with soggy straws.

I'm just replying to the original comment sarcastically joking that giving up plastic straws is the solution when we all know it isn't.

Also the complete irony of the plastic (coated) containers still often used for beverages, but serving with a paper straw... I always hate it if I am too slow to just refuse the straw. Keep that damn thing. I'd rather just drink from the cup.
