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.

Call me cynical, but it says "the fines could total millions of dollars for the companies" and oil companies are expected to self-report on how much excessive methane they produce.

Not sure if it made it into the final version, but the draft version of the regulations let 3rd parties report emissions. And there are instruments in orbit which can spot methane now, in addition to people who show up with IR cameras and spot them from the ground.

No excessive methane found here. Just the normal operating amount.

There are specific quantities written into the Inflation Reduction Act

Gotta love s self report

Good. Oil companies don't listen to much except for when their money is on the line.

Sure, for some companies it may just be a "fee to keep doing what we're doing", there's a lot more we can do and we direly need to reduce our dependence on oil & gas across the board, but this is a start.

The fines will be so small the oil companies will consider it a good deal to pay it and keep polluting.

Here comes repube outrage. “But muh constitutional right to warm the globe!!!!!”

[–] TWeaK@lemm.ee 5 points 9 months ago

I mean it is pretty shitty that they're just venting something that could be used, let alone the fact that methane is an immediate greenhouse gas.

There should be at least two zeroes added to those numbers.

Many people believe that methane leaks are badly undercounted, and that a proper accounting would show that these methane leaks make so-called "natural gas" as damaging as coal, on the basis on grams of CO2 per kWh of electricity generated. (Coal is obscenely dirty which introduces other problems, but that's an issue deserving of its own conversation.) So this is an important first step.
