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:

The Netherlands is more water stressed than...anywhere?! Freshwater management is insane here because we have so much of it.

I was going to comment the opposite.

The Netherlands is actually facing a fresh water crisis because unregulated farmers are pumping large amounts of water up from aquifers, causing them to pull in salt water from the sea which will poison the soil and make the aquifers undrinkable in the long term.

The rivers are too polluted to be safe for agriculture without expensive processing, but the process of fresh water filtering down through ground layers into aquifers makes it potable (long-term salinification notwithstanding).

I suspect the, er, "visual capitalist" disregarded those long-term externalities, or includes a theoretical capacity to clean (or even collect?) fresh water while not including the ability to desalinate salt water.

I also wonder how the graph accounts for water entering a country from another country. Most Dutch water management concerns the sea, which is not included in the graph, and rivers, which mostly come from other nations. If Germany consumed/redirected the Rhine, would that make the Netherlands appear more red on the map?

Also, Bangladesh and Nauru are both more "water stressed" than the Netherlands by your definition. Bangladesh regularly floods because it is a river delta in a monsoon region, and Nauru is an island nation that will be abandoned because sea levels are rising.
