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.

Before synthetic gemstones were trendy and they were truly worthless I bought 5 massive sapphires for like 3 dollars each.

They're on my desk, I see them every day. Every time I play with them I muse about how not so long ago people murdered each other for gems so large and so perfect. Now that anyone can have them though, they're toys.

Gems were always about status, nobody aside from nerds every wanted them because they were beautiful, or because their physical properties and fascinating. Showing how much 'better' you are than someone else was worth more than human lives.

I don't think new methods for making diamond will really help anyone, the nutters will just find new ways to flaunt their power.

I think rich people collect art, these days, right? For inflated prices. And, like, limited wines. Maybe I'm thinking of money launderers.

Diamonds actually have real life practical purpose, like being the tip of a drillhead to dig underground.

Sounds cool. Can I have one?

If you give me your address and pay shipping. Although if you want sick gems the coolest thing you can do is buy rejected lab rough (grade inferior for lasers and shit), and then take it to your local lapidary club and facet it yourself.

I faceted this into trillion but it's too dark to have much brilliance.

Where does one purchase these rejects?

[–] dharmacurious@slrpnk.net 1 points 2 weeks ago (1 children)

Seconding the request on where to purchase rejects. I've always wanted to make jewelry for mom, who has super particular taste in style, but would genuinely prefer something like rejected lab made

Seconding? No firsting.

Um just search lab rough or synthetic rough online. It'll depend where you're located what a good deal is. Aliexpress, eBay, gem dealers around you etc.

e.g. if you live in the terrible empire: https://www.gemsngems.com/product/lab-created-blue-sapphire-rough/
