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.

  • Communities in Indonesia’s Dairi district continue to protest a zinc and lead mine being developed by a Chinese-backed company.
  • They warn the PT Dairi Prima Mineral (DPM) mine poses unacceptable risks to human life and the environment, given the potential for its waste dam to collapse in the earthquake-prone region.
  • There are 11 villages located around or downstream of the proposed tailings dam, making the prospect of its collapse potentially disastrous. Some homes and houses of worship lie less than a kilometer (0.6 miles) from the dam, while an entire village of 2,010 people, called Pandiangan, is just 1.8 km (1.1 mi) from the dam.
  • This would make the project illegal if it was built in China, since that country’s regulations prohibit the construction of a tailings dam within a kilometer of a populated area, according to Emerman.
  • These concerns are borne out in a series of independent analyses of the project’s environmental impact assessment, which experts say fails to live up to the standards the developers claim to follow.
  • Despite the questions over the assessment, the Indonesian government has issued environmental approval for the project, which local communities are now challenging at the Supreme Court.
