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.

Good riddance. I could always tell how inefficient those bulbs were, simply from trying to touch them to change the bulb. All that heat is wasted energy.

Plus there's a lot of neat things we can do with the new LED bulbs, including adding Wi-Fi circuits to make them smart bulbs. And the price of those LED bulbs is dropped so much, I don't even really worry about the price difference anymore.

That's how you can get your very own botnet, courtesy of some guy in China. Most of these shitty IoT crap never get any updates, and will probably serve most of their life as easy access points into your LAN.

I quarantine my IoT stuff in their own VLAN. They should be treated as untrusted devices, because they are, same as any BYOD network. Hack away!
