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.

Yeah, it's just one study but it's part of a bigger picture.

Once humanity discovered fire and basic techniques for preservation it became viable for groups of people to work together and produce a surpluse of highly nutritious food and the ability to store it for later. And the majority of very early human history is centred around either hunting or fishing communities. That's how most humans lived before we eventually came up with agriculture, which was just around 10.000 years ago. We were hunter-gatheres for like 200.000, maybe much longer. That's a timespan that allows for minor gentic adaptations like that, especially if there is a strong evolutionary pressure. Some extreme example would be early civisations in the arctic regions, which sometimes entirly depened on one food source (very often seals).

So I'm pretty confident in saying that taste not just "learned behavior". Of course there are genetic factors involved, it would be aburd if there weren't. We are just animals afterall.
