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 article doesn't really do a great job of answering the titular question. So ... Is the answer "mostly because of policy failure"? Because that is what opening two coal plants in 2024 sounds like to me.

I'm also a little confused how they managed to jump from "renewables are making power cheaper in Japan" in one paragraph to "this is hampered by G7 liking fossil gas" in the next paragraph. (I do share their worry about G7 nations investing in fossil gas too much. My home country Germany has just introduced a gas peaker plant strategy and appears to be over-investing in LNG terminals.)
