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 authors argue that centuries of imperialism, extractive capitalism, and population growth have pushed Earth's ecosystems beyond their limits, and created a broadening pattern of social inequality. The review summarizes the grave threats facing the planet but rejects a "doom and gloom" philosophy. Instead, the authors argue, the threats should motivate swift and substantial actions.

According to the authors, a global economic model focused on wealth accumulation and profit, rather than true sustainability, is a major impediment to decarbonization, conserving natural resources, and ensuring social equity. Therefore, the authors argue, governments should enforce radical, immediate cuts in fossil fuel use, eliminate environmentally harmful subsidies, and restrict trade that generates pollution or unsustainable consumption.

When people hear the words 'not sustainable', I fear that they are not grasping what that implies. If humanity keeps procrastinating on these issues, we are gonna have a bad time.

The people with the power to enact strong, rapid change will be dead when the worst of it hits. So, why the fuck should they care. They got theirs. It is pretty damn disgusting, the lack of empathy, but there is no short term gain from them acting selflessly.
