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.

Idk what's going on but I can't reply to the people who replied to my comment so I'll do it here.

According to this data, approx 50 billion tCO2 per year are emitted worldwide by human action.

https://ourworldindata.org/emissions-by-sector

2t/CO2 per year per person X 6b people= ~12 billion tCO2/year.

Or about 25% is done by BILLIONS of people every year.

Regulations are the only way because corporations have a death grip on society. Even if we reduced individual emissions by 50% as people are saying that's only a 12% difference in emissions, versus 35% if corporations halved their emissions. Creating laws to reduce individual emissions would go over like a lead balloon, and a lot of the cause of individual emissions, if I had to guess, is due to the circumstances around their lives. Availability of public transportation, cost of goods and how their goods are produced, etc. However, corporations have a direct choice in doing these actions.

If you regulate corporations you have a much larger overall affect that if you were to make laws limiting consumption. It's simply more practical in many many ways to force corporations to hit emissions goals than it is to force people. What are you going to do if people emit too much? Fine them? Good luck they're already broke. Jail them? I think we can both agree how that would go. There are many multitudes fewer corporations than there are actual people, so managing and controlling their output is easier from a governmental standpoint.

It's companies making vehicles that emit high amounts of CO2, it's companies making ecological disasters on a global scale, it's companies who are being given tax cuts that could instead go towards fighting this issue. Planning for people to individually emit less isn't as feasible as controlling the source of emissions itself.
