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.

Xi is pushing climate, study shows

Enabling climate acceleration are economic sectors such as land use, China coal, Saudi Aramco, Coal India, Gazprom (Russia), National Iranian Oil — in that order.
Since 2021, China coal sends more carbon in the air than NATO equities and Arab states combined. The China coal sector is increasing capacity and is delivering 12.7 GtCOe in 2024.

Why should how wealthy you are factor into how much you pollute? Per capita is the only sensible measurement here.

The idea is GDP is a measure of activity. So using per GDP allows you to see the efficiency which you are producing "value". That's not a terrible idea in general but it accepts a very narrow definition of value.

GDP is a really flawed measure of how well a society is performing. I wonder what it would look like if we used Gross National Happiness or Total Quality Life Years. Could also think about ecosystem health or biodiversity as a valuable output of a country but that's highly linked to CO2 emissions so wouldnt be meaningful.

Also worth saying whilst per capita is absolutely important as a measure for us to understand the performance of human economic systems the earth systems only respond to gross total emissions.

Creation of value means nothing in the context of climate change. The atmosphere doesn’t say “you’re less at fault because you made so much value for the shareholders”.

The only measure that means anything is absolute emissions, full stop.

I acknowledged this in my last paragraph. We should care about value though and we need to fight for that value to be something positive and meaningful (human and non-human health and wellbeing is a good start imo) not just shareholders.

Ultimately, there is a lot flawed in carbon accounting systems but we do need measures that allow us to assess if individuals, organisations and nations are doing enough and importantly articulate what pathways to zero emissions look like and that does mean trying to work out which processes are producing something we want with low or no emissions or not.
