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.

Biden vs. Trump: Do young climate voters care? The president who signed the biggest climate law in U.S. history has also angered environmentalists by approving fossil fuel projects. (www.politico.com)

To be clear: there's a night-and-day difference between Biden and Trump, with the former having actually taking significant action, and being likely to take more if reelected. Trump will look to maximize both extraction and consumption of fossil fuels in a way that Biden simply didn't and won't.

He's shifted the emissions trajectory of the US in a meaningful way

That's simply not true. Biden doesn't give a shit. He'll be dead before the climate apocalypse occurs, and everyone he works with is paid by big oil to not go "too far" with environmental regulations. Sure he makes it look like he's making a difference, but the fossil fuel lobby has thus far been succesful in preventing any major countries from taking significant action on climate change.

Don't believe me? Here's how world governments are doing at regulating climate change:

You really think Biden, who is fundamentally the same ideology as all previous Democrat presidents, is going to do anything different? It's worth noting Biden was present at the Paris agreement and pushed for weaker language in the agreement to weasel out of the US needing to take any significant action.

To be clear, I think obviously people should vote for him given the alternative. But only because America is a profoundly broken country and that senile old coot is the best option available. I'm just deeply suspect of anyone who says that Biden is actually doing good on the climate, since it's obvious to me that he really isn't.

That graph is a highly misleading way to evaluate a single national leader because China sharply increased their coal burning at the same time the US and EU started to cut emissions.
