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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Imagine if a company said it was working towards achieving NET zero murders by 2050. That's not promising much is it, even without the problems of carbon offsets.
Yet the commercial described in the article sounds like it could do real harm. People might take MORE flights based on it. Perhaps the privledge of advertising is better limitted to companies that are not demonstrably harming the public. We can't trust them to get into the public's heads when their products do so much damage.
I don't understand. If these technologies are important why persue them via pressure on these airline companies? Simply tax them more and fund public research. Why let the research be private where its pace will be unknown and its discoveries hoarded for private profit and competitive edge?
It's a bit hard to restrict advertising like that in the US. In most case, about all you can do is to ask that they not make fraudulent claims, which is what Delta was doing.
The "sustainable aviation fuels" are things we know how to make, but they're either very limited in supply (biofuels, where we're burning a large chunk of the maize and soy crops already) or incredibly expensive (synthetic fuels from captured carbon marketed as 'e-fuels') The corporate research around these isn't really designed to turn them into something which will get used at scale, but seems more like the PR exercises we've seen the fossil fuels industry repeatedly conduct in the past.
The batteries are coming, at least for short-haul flights. The factory to make the first ones with a high enough energy density to support commercial flights is being built as we type.
