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.

I feel like maybe we did these in the petrostates to get them out of the way. The next one is in Brazil with (hopefully) Lula. Let's see how it goes.

COP is no longer fit for purpose and should be reformed.

I have a different take, renewable have arguably crossed the threshold for mass adoption so moving away from fossil fuels is inevitable. These seems like the death pangs of a dying tumour trying to claw its way to relevance. Look at Saudi Arabia's desperate attempts to diversify away from petrodollars.

Renewables are now cheaper, better for your citizens & most importantly much safer for national security, compared to fossil fuels. It is a no brainer for all nations to switch away.

Atleast I hope I'm right.

Chef’s kiss 👌🏻

We all hope you're right.

That is why China and the EU invest so much into green tech. China needs to import a lot of its fossil fuels via ships and the US still has the biggest navy and China would have some problem solving something like the Red Sea Crisis right now. For the EU Russia was a massive wake up call. The only big one who does not see this is the US, which has a lot of fossil fuels.

It's even worse, incentive-wise: The US has a lot of "good" oil, which needs less refinement. They sell that stuff, since it's valuable.

They also pretty much have the best refineries for low-quality oil, which they can buy for cheap.

So, they industry, imports and exports rely on oil.

We are prisoners of the wealthy’s greed.
