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.

New preliminary research suggests that a combination of higher atmospheric CO2 and hotter temperatures contribute to a reduction in nutritional quality in food crops, with serious implications for human health and wellbeing.

It's not just climate, it's the crop breeding specialists. The sector demands quantity over quality, like in many other scenarios, and the people who develop new cultivars tend to focus on that quantity. When we have regulations for nutrient density or the consumers demand it, we'll see that change. Climate is adding to this problem, yes.

Note that it affects all biomass, including the second-hand sources of amino acids, lipids, sugars and other nutrients: animals.

I would much prefer smaller, better-tasting, more nutritionally beneficial crops. My bf and I want to start growing our own at some point.

Of course. I'm sure that you understand that less quantity also means that you eat less... or you plant more.
