2050 is so far into the future its meaningless. If they were serious, it would be early to mid 2030s. What's worse is that renewable energy is very viable and there are tons of tax credits to offset the investment, so it also seems like poor corporate strategy to not invest.

Exactly! In the report, the companies that do have meaningful goals of at least 80% emissions reductions by 2030 do WAY better than the rest of the companies! But a 2050 goal is meaningless, and “net” zero by 2050 is even more meaningless because they can claim to fill it with carbon capture or carbon credits.

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.
