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.

Offsetting global fossil fuel stores by planting trees is impossible (www.newscientist.com)

Archived link of the article

It would be nearly impossible to plant enough trees to compensate for the climate impact of burning through the world’s fossil fuel reserves. Offsetting the estimated 182 billion tonnes of carbon held in the reserves of the world’s largest fossil fuel companies would require covering more land with trees than the entirety of North and Central America.

“There simply isn’t enough land available for the level of afforestation that would be needed to offset fossil fuel-related emissions,”

The study: Carbon offsetting of fossil fuel emissions through afforestation is limited by financial viability and spatial requirements

Me too. And as I get older and older the more I like to see my leafy friends growing to the point I get to sit in the shade of one of them in a hot summer day as I listen to the birds chirping up there. There is no feeling like knowing I had some part in creating that moment. That makes me feel not that I created that moment, because I didn't, that was was the sun and the rain, and all the worms and microbes and bacteria all the way. I just played a tiny part in it and that makes me feel one with everything in that moment.
