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.

Climate scientist 'could lose job' for refusing to fly (phys.org)

A climate scientist on Wednesday said he was being threatened with the sack for refusing to fly back to Germany from a research trip in Papua New Guinea.

Gianluca Grimalda, a senior researcher at the Kiel Institute for the World Economy (IfW Kiel), has spent six months investigating the social effects of climate change in the Pacific island country.

Grimalda made most of the outward trip to Papua New Guinea by land and sea, taking 35 days to travel around 16,000 kilometers.

He wished to return entirely by cargo ships, ferries, trains and buses, he said in a statement shared by the campaign group Scientist Rebellion.

But the IfW Kiel is allegedly insisting approval for his trip ran out on September 10 and he must return immediately by plane.

I think it's mainly two reasons: Consciousness, and trying to make the world a better place.

People similarly refuse to participate in other things which are done anyways. Think about veggies, Nestle, refusing to work in certain industries or for certain employers, reddit blackout, fair trade products.

People abstain from what they deem wrong to have no part in it. And to use the power they have to not support what they deem wrong, maybe even shed light on it and inspire others.

When enough people do the same, it absolutely can have real world consequences. Change has to start somewhere.

I also refuse to fly, but my commute isn't 16000km either.

Very good points and well written.
