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.

My old school didn't understand why none of us wanted to use the shiny new dark green playground equipment on the large flat freshly sealed blacktop.

Never mind the fact that it's too hot on the pavement, the tar sealant smells horrible, and the color choice of the equipment guarantees 2nd degree burns...

We wanted the grass and wooden equipment back. But the school though wood was too much maintenance, And grass grows too much.

I'm not gonna go check to see if kids are even using it anymore, but satellite imagery shows the playground is still just as gross.

My kids school has done some of this. Next to his kindergarten class is a little patio where they eat snacks and spend a lot of the day. It used to be concrete, but now it's all wood chips and little logs for stools. The shade is lacking, but it has trees, they're just a bit young. When they fill out, it'll be amazing.

I remember having a playground and a big field during recess. At least half the time, most of us played in the big field.

Kids are great at making fun from nothing, so this is a great move.
