Terror attacks on shipping in the Red Sea have led to changes in cloud patterns thousands of miles away, reveals new research.

The "ripple effects" of a shift in global trade routes on clouds were uncovered by American scientists.

When attacks disrupted shipping lanes in the Red Sea, few imagined the knock-on effects would reach the clouds over the South Atlantic.

But for Florida State University atmospheric scientist Dr. Michael Diamond , the rerouting of cargo ships offered a rare opportunity to clarify how much cleaner fuels change how clouds form.

He and his colleagues showed that new fuel regulations that cut sulfur by around 80% also lowered cloud droplet formation by about 67% compared with earlier, dirtier fuels.

Dr. Diamond said: “The unexpected rerouti
