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 took this picture this morning. Mid December in Belgium and it is definitely not normal. The following scenario rolled out in my head: what if all plants bloom in December, don't get pollinated, then when bees wake up there's no food, they are decimated. Wouldn't that be a huge biological collapse?

I'm no expert in anything, just wanted to share this picture and thoughts

So how does that work, does this tree just wait in full bloom for insects to wake up? (Not doubting what you're saying, genuinely curious)

They can sometimes have flowers as late as april, but usually they just don't get pollinated at all and don't produce any fruit. They're ornamental hybrids that don't exist in the wild, so they don't really need a viable way of reproduction.

Interesting, thank you for teaching me a thing!
