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.

Researchers have discovered that waste from the global apparel industry is leaking millions of tons of plastic into the environment each year and may be getting worse over time.

I switched to cotton t-shirts 5-10 years ago, thinking the same thing. However my first set of cotton t-shirts has worn out and needed to be replaced, whereas I still have polyester t-shirts from before that that look much nicer.

Polyester has advantages in durability, stain resistance, wrinkle resistance, and can be much thinner and lighter. I’m not entirely sure cotton is really better

Some studies estimate about a third of microplastic pollution comes from synthetic textiles. Cotton may require more water and land but at least it doesn’t produce more microplastics.

Polyester might look nicer longer but it feels all gross and like… almost slimy on the skin. Plus it stinks.
