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.

Oil industry executives and analysts say the current number of 448 oil-producing leases is unlikely to grow significantly, even if Trump makes good on promises to expand leasing opportunities and expedite drilling permits.

The market is saturated with oil, making companies reluctant to spend more money drilling because the added product will likely push prices down, cutting into profits.

“It’s not the regulations that are getting in the way, it’s the economics,” said Hugh Daigle, a professor of petroleum engineering at the University of Texas in Austin. “It’s true that there are a bunch of undeveloped leases in the Gulf, and it’ll stay that way if we continue to see low or stagnant oil prices.”

Most of Russias oil exports go through ports in the European part of Russia. Those are currently being attacked by Ukraine. For example Ukraine managed to hit an oil pumping station shutting down the oil port of Ust-Luga, which handles 20% of Russian oil exports.
