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.

I'm genuinely not sure if you are a troll and trying to be intentionally argumentative or what...

But your argument is that the entire theory of evolution is proven wrong by crabs dying en masse because of climate change, because humans are racist and commit genocides against each other? Or did you just move the goal posts on this discussion about crabs and try to call me racist in the process for shits and giggles? Like you took such a hard turn in the discussion and the only logic is that you are probably gish galloping the discussion and it would be a waste of energy to continue.

the argument is there are winners and losers. these are chosen, evolution isn't simply a competitive, efficient, marketplace of genetics.

this hasn't changed

These are chosen

By what exactly?

[–] lntl@lemmy.ml -2 points 1 year ago

you obviously know the answer already and it's not an efficient marketplace of genetics...

While i don't think Darwin is wrong outright like some Jesus folks would say. A critique i have is that model is simple enough and accurate enough that simple people can understand it and feel like they know something... but it's not quite sophisticated enough to describe all of the forces at play.
