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.

“The project is crucial for helping the state meet a deluge of new electricity demand, as Virginia is at the center of the nationwide boom in data-center construction.”

So it will do absolutely nothing to reduce fossil fuel usage?

It'll reduce fossil fuel use that otherwise would've been used to power that place, but sounds like it won't be a net reduction in emissions. Better than an increase, and if the AI bubble pops, perhaps it will be able to reduce emissions after all, if the datacenters are shut down.

I understand that. Unfortunately, we are at a point in time, where a net reduction is extremely necessary. But yes, the problem is not the wind farm. The problem is the ai bubble.
