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.

Instead, Cerezo-Mota expects the world to heat by a catastrophic 3C this century, soaring past the internationally agreed 1.5C target and delivering enormous suffering to billions of people. This is her optimistic view, she says.

Which mentality?

That human life is worth living, but circumstances may not always be, so we reserve the right to choose our own exit from it, or that choosing to live is saying life is better than death?

You're teaching your children to take their own lives when times are rough. I'm not besmirching your freedom to "exit" or anyone's choice but who are you, me, your kids, to make a decision of that final exit based off of criteria that is subjective and impossible to understand. Not even the very wise can see the end, apocalyptic world or not.

Tell me where I said I'd teach a child suicide should be front of mind. All I mean is they should get to choose if they live - in response to someone pleading that we all stop having children.

I want to have a child. Why should I not, because the world could be in rough shape due to climate catastrophe? I'll let them make that call and I hope they don't have to.
