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.

You can still order cheap panels and batteries online in the USA. DIY = freedom

I didn't read the article, but to back up what the headline says I have seen the price of batteries dramatically decrease over the last few years. For example, about 3 years ago I got some 200Ah lead gel-type batteries for my solar setup that cost over $400 each, and one of them is already failing. Last year and this year I bought LiFePO4 batteries that are higher capacity for less than the lead ones cost. The first batch was near $400 each for 300Ah LiFePO4 batteries, and this year I got more of the same for about $250 each. Lead is dead for solar. LiFePO4 is very cheap relatively now. The next step is probably Sodium-ion batteries - should be cheaper and more reliable than LiFePO4 batteries.

As someone who has access to about 3kw of solar panels, and wants to cut down on my electricity bill, where did you manage to get batteries so cheap? I've been burned on 18650s from supposedly reliable retailers before...

The usual junk markets like Amazon, eBay, AlliExpress. There are probably better places to shop but I just found deals and bought some without much planning involved.
