Climate - truthful information about climate, related activism and politics.

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'll note that several oil majors have made big bets in the past few weeks to the effect that oil and gas consumption will continue to rise for decades to come. If we succeed in maintaining a civilization-supporting planet, people who have not divested from fossil fuels industry will lose a lot of money.

There are a good number of possible transitions of fossil fuel assets, but they need to be done right. Refining is just chemistry and a lot of the products can also be refined from plant based oils and biogas. So manufacturing plastics, lubricants, biofuels and so forth. The intressting term is biorefinery. Also refineries are good places for hydrogen based chemical process. They have a wonderfull grid connection already and quite a lot of great equipment for that kind of work. Then drilling is actually a usefull skill for geothermal energy, which is a wonderfull renewable energy form especially for heating. A lot of offshore wind technology comes from offshore oil rigs as well, so that is a usefull skill. Petrol stations are mostly stores anyway and can easily be converted to be charging stations with a store. A good bit of gas infrastructure can be used for hydrogen, if it becomes availbale in a green form at scale.

So they absolutly could turn around, but there is more money in fossil fuels right now, so they do that instead.

Thanks for all the info! Sounds like they need the right incentive. If only governments had ways to nudge businesses to do or not do things...
