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.

“I hate wind,” Trump told the executives over a meal of chopped steak at his Mar-a-Lago Club and resort in Florida, according to a person with knowledge of the meeting, who spoke on the condition of anonymity to describe a private conversation.

If you're an American, and you want to stop this, here's what you need to do:

Solar is vastly cheaper -- it costs so little that it becomes hard to model it. Wind works out to ~$32/MWh in the US. Compare that to fossil gas at $5-$30/MWh, depending on the region, and wind is decidedly not out-competing gas. At least not yet. If it continues to get invested in and allowed to deployed, the learning curves on it should be able to bring its price down quite a lot, though.

And yes, those are LCA prices. No one is going to be as simplistic as to just look at one cost center and ignore the other the real costs of energy generation.

Energy is sold at market prices, aside from that which is sold via purchase agreements with utilities that set the prices manually (this happened a lot with coal and ended up being a huge blunder for many utilities who later had to go back and buy out coal plants just to shut them down because they were stupid expensive). Solar being very profitable because fossil energy is pumping up the price is a good thing, not a bad thing -- this creates huge market incentives to scale up solar production, which is exactly what is actually happening all over the country right now. There's no universe in which it is a "travesty" that solar or any renewable has profit potential to deploy right now. We need as much of it deployed as fast as possible. We need it to be profitable enough to get projects off the ground, especially while interest rates are still painfully high and utility interconnection queues are years long and interconnection is often punishingly expensive for no good reason.

This is a discussion about US climate policy. The inflation reduction act is the most important piece of legislation in US history on the subject of climate. Maybe even including the clean air and water acts. I'd encourage you to read up on it.

And I'd encourage you not to use initialisms that are unfamiliar to the vast majority of people on a global forum without explaining them

Americans are the first to complain when it happens the other way around because their worldview is so blinkered!

The IRA is definitely the Irish Republican Army 😂

Being ex British Forces, this always makes me laugh.

I was wondering what it had to do with Individual Retirement Accounts.
