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.

  • Torrential rains drench large swathes of China
  • Displacing thousands and exposing China's ageing flood defences
  • A high-pressure system is also baking other parts of the country
  • Extreme weather is increasingly challenging Chinese officials

[...]

The world's No.2 economy faces growing threats from extreme weather, which meteorologists link to climate change. Each year, the impact threatens to wipe out tens of billions of dollars worth of commercial activity, alongside loss of life, as ageing flood defences are overwhelmed and infrastructure gaps - such as limited access to air conditioning - are exposed.

And the US in it's infinite wisdom just put their climate scientists on indefinite unpaid leave
