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.

A mining magnate and climate campaigner at the same time?

It's possible; while shifting off fossil fuels cuts the overall need for mining sharply, it does still involve the use of rare earths, lithium, copper, and other metals

Plus, people still need everything from kitchenware to trains in a net zero society, which means more metal. While it can be recycled, we need a lot more to get to a point where everyone has the same standerd of living, even before mentioning stone, gravel, clay, etc. Outside of coal and oil producing ingredients like cobalt, i’d imagine that overall mining demand would be rather steady even if a lot of carbon neutral technologies didn’t require more metal inputs.

No, because coal, oil, and gas extraction are also mining activities. And those get used only once, whereas metals an such get used again and again and again. So there's a huge cut in total mining.

Coal yes, but typically oil and gas are the drilling in “drilling and mining sector”.

Also seems to be owning lots of animal farms, but somehow he doesnt care how that might impact the climate
