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:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

A pub in California is pulling carbon dioxide from the air to carbonate pints. If the business model works, it could give the broader carbon-capture industry a boost.

The dissolved oxygen has to leave the beer somehow to get the yeast to produce alcohol. You could use some energy-intensive process to remove the oxygen, but otherwise it naturally gets turned into the CO2 beer drinkers expect. And I doubt that energy-intensive process would be worth it in the end.

Though maybe the naturally present oxygen isn't enough to make it as carbonated as consumers expect, and more air or CO2 is pumped in to make it more carbonated. In that case using captured CO2 instead of letting the yeast turn some more of the wheat into CO2 would make a difference.
