Climate - truthful information about climate, related activism and politics.

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 seem to go into much detail but what are the risks of introducing salt water into the areas below the clouds when it condenses into rain?

If this is done on a global scale, there are multiple problems:

  • the temperature would get lower artificially, until it isn't maintained. Should we continue business as usual with fossile fuels?
  • can it be done everywhere at the same time?
  • what is the impact on the water pattern on a global scale?

Changing "business as usual" with fossil fuels is a separate issue that will happen or not happen regardless of the global temperature. It's something that will have to be done as a task in its own right. Lowering the temperature would prevent millions of deaths by starvation in the meantime, whether we change "business as usual" or not.

  • can it be done everywhere at the same time?
  • what is the impact on the water pattern on a global scale?

Maybe we should do some tests?
