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.

So there's plastic accumulating in testicles and lead contamination in the tampons. The future is insane.

In all seriousness though, when I was having the water tested at my house a few years ago, I was told there's no safe amount of lead to have in drinking water, and everything I looked up agreed with that.

So now I'm confused. Either there's safe levels or not. Or do they mean any amount that sets off this standardized test strip is unsafe?

I'm sure these researchers are using more sensitive tests, but corporations at least deserve the side eye and an investigation for the 'no lead' rule not applying to their products. Especially products like tampons...something that's in contact with mucus membranes for hours at a time.

Hey, so I am by no means an expert but have experience in environmental public health. We talk a lot about risk mitigation. A lot of people smarter than me measure what chemicals are appropriate levels in certain products. Because while yes, it is true that no amount of lead is good for you, there are so many factors that come into play that you have to contend with the fact that there will be a number of chemicals that will be occurring within our environment that can’t always be controlled, so they end up in our products. It’s a really fascinating field, I have a textbook recommendation that’s really good if anyone is interested - it isn’t open-source, though. :/
