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.

A showdown over deep sea mining is taking place in the Pacific (phys.org)

Activists from Greenpeace International have boarded a ship that is conducting deep sea mining research in the Pacific Ocean, vowing to occupy the vessel until it abandons the expedition.

It's the latest collision between a nascent industry intent on mining the seabed for minerals potentially worth trillions of dollars, and environmentalists and scientists who warn that doing so would irreparably harm biodiverse deep sea ecosystems.

The confrontation unfolding on the high seas comes as the expedition's backer, The Metals Company (TMC), prepares to apply to become the first venture licensed to conduct deep sea mining in international waters. TMC has said it will submit its application after a July 2024 meeting of the International Seabed Authority (ISA), the United Nations-affiliated organization that regulates deep sea mining.

They have done enough damage mining on land. Good on greenpeace for not letting them go through with this Ecocide.

You know, there's a discordian game that seems pretty appropriate right now.
