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.

...one thousand trucks poured into the national park, offloading over 12,000 metric tons of sticky, mealy, orange compost onto the worn-out plot. The site was left untouched and largely unexamined for over a decade. A sign was placed to ensure future researchers could locate and study it.

16 years later, Janzen dispatched graduate student Timothy Treuer to look for the site where the food waste was dumped.

Treuer initially set out to locate the large placard that marked the plot — and failed.

But there is a lot of growth. Which makes me wonder why people say to not compost citrus peels.

That was my reaction too! I read the headline and immediately thought "oh god they killed it didn't they". I was shocked to find out it was a resounding success, at least in comparison to the alternative of doing nothing.

It's probably got something to do with local soil ecology or rainfall amounts, so there may still be some merit to not composting your orange peels, but this definitely makes me want to learn more about why this guidance is so heavily repeated.

I compost all my food scraps and leftovers from anything that I eat.

My personal experience is that normal food waste will not cause problems with your compost. Everything composts eventually.

why this guidance is so heavily repeated.

Not only repeated, but blindly repeated.
