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.

Wow, it’s been a while since I’ve heard someone spout this much hopium and half-truths.

2.1C by 2100?? That’s just delusional. We’ll hit that by 2035 at the latest.

Please find a better source for global warming information. Perhaps start with Hansen.

I love how the graphs overlap up to our current time but it optimistically looks for it to diverge starting basically just now but we won't really be able to tell till like 2050 once we have enough of a significant deviation to maybe see we are on a better track. We have done stuff but I would not call it a lot. I would call it rather minimal.

Simon Clark is great, really well produced and entertaining videos. I think he goes a little overboard with the relentless optimism in this one but it's worth watching anyway.
