Climate - truthful information about climate, related activism and politics.

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.

It remains to come up with an environmentally friendly analog for lithium-ion batteries in electric cars, but this is probably for the distant future

There's sodium batteries that are picking up right now

They look pretty damn promising from a safety and environmently friendly standpoint

It will be a while for sodium batteries to solve this problem. They have low energy density, both by weight and volume. I expect it to change enough to be a better choice relatively soon. In the meantime, lithium recycling is picking up, which will reduce the burden of the increased demand for lithium.

They're pretty comparable currently to LiFePO4 batteries currently in terms of energy density. And they're seeing use in electric vehicles in China. I'd say they're popping off for sure.

And just last month the first sodium battery manufacturing plant opened in the US.

Natron Energy, the American sodium battery manufacturer, is only talking about making EV fast chargers, not actual EV batteries. I'm guessing the big reason is energy density. I'm not sure what the range of the Chinese EVs are, but I suspect it won't be enough to attract North American consumers at this time, although I expect that will change. Also, in other locations where the population density is higher, lower range probably isn't as big of a factor.
