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.

Yes by emitting less co2 and by protecting vulnerable sea life

But did you ever think of corporate profits? Those poor shareholders!!! 😭😭😭

Okay, now what if we "try" anything but that?

Seems we'll do anything to avoid riding bicycles and not flying.

The first edition of "Waves and Beaches" (https://www.goodreads.com/book/show/1571715.Waves_and_Beaches) by eminent oceanographer Willard Bascom in 1963 advocated throwing human-made garbage into the ocean instead of landfill. His argument was that the ocean was so much bigger, the bad stuff would get diluted, and eventually sink to the ocean floor out of harm's way.

The most recent posthumous edition in 2021 (https://www.patagonia.com/product/waves-and-beaches-the-powerful-dynamics-of-sea-and-coast-book/BK855.html) updated by a co-author and with gorgeous graphics, by the way, tries to handwave away all that by explaining 'Eh, that was then, we know so much more now.' I have both.

Point is, scientists can be myopically stupid as well. Laws of unintended consequence, mongoose and snake story, yada yada.

Please don't throw chemicals into the ocean.

As corporate interest in ocean carbon removal grows, researchers from Woods Hole Oceanographic Institution are testing the safety and effectiveness of one such technique in the Gulf of Maine.

Yes anything but slow growth need arrow to go up. Can we just kill these fuckers already. Where are all the people saying Luigi started something haven't seen any other billionaires die.

[–] dickalan@lemmy.world 2 points 1 month ago

You are stuck in a algorithm Hole, at least five CEOs have died in America since Luigi

It seems that someone noticed that absorbing CO2 leads to ocean acidity rising (the carbonate ion, CO3, is a negatively charged ion with a nominal charge of -2).

Neutralizing CO3 by providing it something permanent to bind with - for example by forming NaHCO3 - will likely have the desired effect (nobody goes testing with a ship without first testing in a lab)...

...but the scale of the task makes me doubt if this is a feasible / reasonable approach. All that sodium to make soda would have to be produced somehow, without emitting almost any CO2. This, I have doubts about feasibility.

As the world struggles to stay below the 1.5-degree Celsius global warming threshold

Oh, honey. We accelerated past that just last year. We’re solidly on the path to +4℃, and likely a lot more than that.

They keep coming up with all these excuses to avoid stopping pollution at its source.
