The planet seems to be warming faster. Some attribute it to massive amounts of water blown into the stratosphere by a 2022 vulcanic eruption. Others see it simply as a result of the rapidly increasing methane concentration in the atmosphere. Meanwhile its impossible to stop airtraffic because all the governments are too corrupt to limit it (although it is discouraged indirectly because its hard to find people that want to work in an airport due to the health hazard).
People that work on solar radiation management have often suggested injecting sulfur dioxide in the atmosphere, a lot like vulcanos do, which would reflect sunlight back into space and keep Earth cooler. The recent laws that required removal of it from shipping fuels is said to have caused an increase in global temperatures.
As airlines are not stopping any time soon, maybe we should add sulfurdioxide to kerosine so that the reflective particles can be spread while the planes are flying. They already cause cooling because of the condensation trails they leave in their wake. Another advantage could be to provide nucleation points for rain. In some cases that may be a good thing, to avoid accumulation of to much moiture in the atmosphere.
It is important to cool the atmosphere simply because life can’t stand too much heat. As long as we can grow crops and eat we can work on solutions (at least the tiny nr of people that manage to escape bank domination). Heat that is absorbed by Earth’s oceans my stay ther for quite some time. There needs to be at least attempts to prevent rapid warming because we will not recover from it. We have once chance, one opportunity and we can’t keep circling around because someone sees a risk forever.
