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.

Huh, TIL you can put it back in the ground. I was under the impression it had to be burned off.

Yep! There are two types of oil wells, producers and injectors. Producers produce raw production fluids and gas. Those production fluids/gases need to go through a 3-phase separate vessel to separate the oil, water, and gas. The water and gas is sent back into the ground with the injection wells. The reason for this is to maintain the pressure of the reservoir underground, and to dispose of the fluids/gases.

Some amount of gas is flared (burned) off from the separation facility, and also from refineries. The purpose of the flare is for process safety. If there's an overpressure event, or an equipment shutdown, all the gas production from the field needs to go somewhere while the production wells are shutdown. For that time period, any gas is burned off to prevent a catastrophic failure in the facility.

The amount of gas being flared is monitored and regulated, and any flare event is recorded and reported to the appropriate agencies, generally the EPA, and Relevant state agencies.
