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.

Regenerative agriculture is also super popular in CR (no doubt tied to the general support for environmental well-being among the population that the article points out). I suspect these help ease the impact of territory fragmentation by essentially providing hospitable corridors for wildlife.

And using ecologist E.O. Wilson's principle that saving 50% of all the ecosystems will save about 80% of the species found in them, you can see what a big deal Costa Rica's achievement is.

Further reading on the 50/80

It was inspiration to many countries, including Canada, to make more National Parks.

The article links to recordings of Costa Rica's' forets. Those are 30 minutes recording of ambient noise, wind and flora, each tied to a specific location on a map.

Those make for great ambient sound for reading, or for falling asleep (set a timer!).
