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:

The California Energy Commission, the state agency that oversees energy policy, approved a $1.4 billion plan Wednesday that regulators said would result in nearly 17,000 new chargers for passenger vehicles statewide, adding to the more than 152,000 public and private chargers available today. The money will be spent over the next four years. In a news release, state regulators said least 50 percent of the funds would go to parts of the state that bear a disproportionate share of pollution, such as communities near major highways, oil refineries and landfills.
