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.

Since it launched a notification system in 2022, IMEO has told companies and governments about more than 1,100 giant methane clouds escaping from oil and gas facilities. Yet the number of releases that it's verified have been halted "can be counted on two hands, maybe one," Caltagirone said.

The 12 members of the Oil and Gas Climate Initiative, which includes Saudi Arabia's Aramco, Exxon Mobil Corp. and China National Petroleum Corp., say they've halved emissions of the gas since 2017.

Yet methane emissions from the fossil fuel industry, including coal mining, remain close to a record level set in 2019 as supply continues to expand, according to International Energy Agency data.

Methane emissions from 13 of the world's major fossil fuel producing regions have risen 7% from 2020 to 2023, according to Kayrros SA, a satellite-data analysis company.
