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.

"All of humanity could share a prosperous, equitable future but the space for development is rapidly shrinking under pressure from a wealthy minority of ultra-consumers, a groundbreaking study has shown.

Growing environmental degradation and climate instability have pushed the Earth beyond a series of safe planetary boundaries, say the authors from the Earth Commission, but it still remains possible to carve out a “safe and just space” that would enable everyone to thrive.

That utopian outcome would depend on a radical transformation of global politics, economics and society to ensure a fairer distribution of resources, a rapid phase-out of fossil fuels and the widespread adoption of low-carbon, sustainable technologies and lifestyles, it said.

This would probably mean that limits have to be placed on excess consumption and that taxes have to be used to address inequality and raise revenue for investment in technology and infrastructure.

The scale of the required change will alarm many governments, acknowledged one of the lead authors. “It won’t be immediately welcomed. To some extent, it is frightening, but it shows that there is still a space for people and other species,” said Joyeeta Gupta, a former co-chair of the Earth Commission and a professor of environment and development in the global south at the University of Amsterdam..."

I just know these "ultra-consumers" won't give up their power willingly to enable this degrowth and construction of these "safe and just" places. We need radical worldwide reforms yesterday, but our planet and government is completely captured by selfish captalistic interests.

You can't threaten something that never existed
