In fact, almost all of the top 20 fossil fuel-producing countries plan to produce more oil, gas and coal in 2030 than they do today. If those projections hold, the world would overshoot the amount of fossil fuels consistent with limiting warming to 2 degrees Celsius — the level scientists say would result in vastly more life-threatening heat waves, drought and coastal flooding.

“Governments are literally doubling down on fossil fuel production; that spells double trouble for people and planet,” António Guterres, the United Nations secretary general, said in a statement accompanying the report. “We cannot address climate catastrophe without tackling its root cause: fossil fuel dependence.”

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.
