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.

  • China's proposed coal mine developments risk creating an oversupply and derailing climate goals, according to Global Energy Monitor.
  • The scale of China's coal ambitions threatens to overwhelm its own, and global, climate goals, with the country accounting for 60% of all proposed mine capacity worldwide.
  • Without drastically scaling back plans for new mine capacity, the world could see a massive rise in potent methane emissions that would make it all but impossible to reach the goals of the Paris Agreement, said Dorothy Mei, project manager of the Global Coal Mine Tracker at GEM.

More than 450 sites are in development across China, with nearly 40% under construction or in test operation, according to the California-based researcher, which promotes clean energy use. If they are all built, their combined capacity of 1.35 billion tons a year would surpass that operating in Indonesia and Australia, the biggest exporters of the fuel for power generation and steelmaking.

The scale of China’s coal ambitions threatens to overwhelm its own, and global, climate goals. The country accounts for 60% of all proposed mine capacity worldwide, and its buildout alone would generate 80% of the methane emissions tied to planned projects, GEM said. Methane is more than 80 times more potent than carbon dioxide over a 20-year period.

“Without drastically scaling back plans for new mine capacity, the world could see a massive rise in potent methane emissions that would make it all but impossible to reach the goals of the Paris Agreement,” said Dorothy Mei, project manager of the Global Coal Mine Tracker at GEM.

This strikes me as unlikely to be used on anything more than a few smal locations
