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.

So far i have never replaced any LED bulbs, and the oldest ones i have are 15+ years old.

LED strips though, where a single dead led can bring down the whole strip, are absolutely a non sensical idea.

IME, LED whining gets me to replace them before they actually die. For old people who can't hear it, they should last longer.

Well I've replaced over 10 in like 3 years. They can get much hotter than incandescent, which can damage the internal circuitry. Perhaps personal experience isn't the best gauge of reliability
