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.

That's certainly not normal. I've seen numerous recordings of voice-capable sirens from TN and I've never seen one broadcast any EAS messages. Usually there's pre-recorded messages like "Tornado warning. This is a tornado warning. Residents should immediately take cover." stored on the controller which is used for such cases. For the siren to be doing what you're describing means something is seriously wrong with your sirens. Probably an incompetent EMA manager.

I obviously refuse to tell you what specific part of Tennessee I'm in but I'll try to find someone to email about it.

Definitely get in contact woth with your local EMA. With storms only getting worse and more frequent it's pretty urgent.
