Have we accidentally made climate change worse by cutting pollution from big, ocean-going ships? A new paper from a team of NASA scientists has pushed one of the most controversial topics in climate science into high gear., a major reduction in emissions of sulphur dioxide in 2020, following the introduction of new, international shipping fuel regulations, led to a"termination shock" that they say could add 0.

Writing on social media, study author Tianle Yuan, a research scientist at the Joint Center for Earth Systems Technology, said the effect was akin to an"inadvertent geoengineering event." Speaking to media of his team's findings, he suggested:"If our calculation is right, that would suggest this decade will be really warm."

Geoengineering efforts to cool the Earth, meanwhile, have been publicly objected to by hundreds of prominent climate scientists. Since 2021, thehas been coordinating researchers to push back against the development of what it calls"a risky and poorly understood set of technologies that seek to intentionally manage incoming sunlight at planetary scale."
