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.

Where do you store all that endless salt though? Or are you going to salinate the oceans further?

[–] [email protected] 1 points 1 day ago

Water Cycle 101: The oceans are salty because rain water has been flushing salt downstream for billions of years. Salt also collects in endorheic basins such as the Great Salt Lake and Mono Lake, for the same reason. Rain clouds form primarily from evaporation of ocean water, which leaves behind slightly increased salinity, although its effect is widely geographically distributed.

There’s a difference between that distributed evaporation and the concentrated salinity increase of effluent from a reverse osmosis desalination plant or a hypothetical hydrogen plant, but the basic answer is yes, leave the salt in the ocean. It will be fine.
