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.

Amphibian road mortality drops by over 80% with wildlife underpasses, study shows | ScienceDaily (www.sciencedaily.com)

Frogs, salamanders, and other amphibians around the world face mounting threats from a devastating fungus, climate change, habitat loss -- and road mortality. Among these, roads pose a uniquely immediate danger by cutting through critical migration corridors, allowing vehicles to crush millions of animals each year.

Now, a new, first-of-its-kind study offers powerful evidence that a simple intervention -- wildlife underpass tunnels -- can dramatically reduce these amphibian deaths and help preserve ecosystems.

In research spanning more than a decade, scientists and citizens from the University of Vermont, the Vermont Agency of Natural Resources, and the local community assessed the effectiveness of two wildlife underpasses installed under a road in Monkton, Vermont. The results were striking: an 80.2% reduction in amphibian deaths.
