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.

Would that not be 4 hours of not consuming non-renewables? Like not burning so much coal is a good thing no?

Are we arguing about the measure of progress in the United States? Cuz buddy I'll take any progress at this point.

Are we arguing? I thought we were talking ๐Ÿคท . Yes, but that also means that the rest of the time the energy has to come from somewhere. Like a coal power plant or similar. So this photovoltaic power plant is not a complete replacement for old power plant, but more like a partial one while still relying of fossil fuel, especially during winter and cloudy days.

We typically use more power during the day (industry, mostly), so the solar helps us reduce carbon based infrastructure need even without batteries. And it's just a baby step in the progression to renewables. Yes, we have a long way to go.

As all the world has. If we really want to prevent CO~2~ (and other bad) emissions, we need energy storage and a lot of it. Or nuclear. That said, these are steps (without proper energy storage) in right direction, but only as long as they replace energy from fossil fuel power plants.

Sorry, I might have gotten a little defensive there.

My point is if it supplements their energy consumption with cleaner energy it's a good thing.

Even if its for a couple minutes or a couple hours its a positive improvement.

No worries. It is, if it replaces fossil fuels. But it soon gets tricky if it is supposed to be a stable source of energy. For that we'd need awful lot of energy storage, probably in some form of batteries (sodium perhaps). Today it's relatively easy to slap solar panels everywhere, but it's not that easy to provide energy outside of daylight.

Yes we need to go further but, sometimes it feels like we make perfect the enemy of progress.

I'd love to see a large public works project that aims to increase the energy storage capacity/development across the world.

I don't feel like we get there by focusing on it not being a complete solution.
