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.

The colors here are confusing because the color scale grades the temp gain, but that isn't the information that is claimed to be shown, which is whether or not they are meeting their goals.

I disagree because it portrays whether they are meeting their goals and a lot more information.

Compare the two columns and if they are the same color, they are meeting their goals.

Compare two countries to see which sets stricter goals compared to each other, or is achieving better results compared to each other.

You're right. However, I feel like the left and right columns could've been linked with a gradient to more clearly show their relationship.

I always struggle with colors because I'm colorblind, and grokking this chart at a glance is hard.

Even if we ignore the fact it is talking about emission goals, but the metrics are in celcius. A good graphic would include an indication that they're meeting their goals. Either having two groupings or an additional column to provide a quick way to see that information.
