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.

Without that interconnect there is a danger to people working to repair the grid in the event of need for service. I'm not a fan of spyware meters that can map out when you use individual appliances in your home but there is a safety reason for those interconnects.

True, but I've had two grid-tie inverters, and both have had anti islanding protection and would not function when there is no utility power. Pretty much all grie-tie inverters have that protection.

I'm specifically referring to the interconnect agreement, though, which is where you have to jump through a bunch of hoops, fill out a bunch of forms, pay a fee, wait for the power company to come and inspect it, and get the utility provider's blessing before you can hook in a grie-tie inverter and export even a fraction of a watt.

And you have to go through that process every time there's a change to your system. e.g. If I start out with a 400 watt balcony solar kit, get that approved, and want to add another 400w kit, I would have to file new paperwork, pay another fee, wait for inspection, etc.

I'm all for reasonable safety measures, but the power company in my area is clearly doing all it can to pay lip service to "yes, we support balcony solar" while also making it as painful as possible for homeowners to actually implement it.

That's misinformation. These panels disconnect automatically at the very moment there is no power in their grid connection.
