On Tuesday they said it made heavy rainfall in the region up to 50 times more likely.
That's according to scientists with the World Weather Attribution - an international research collaboration that studies climate change.
The powerful storm - that hit the country on September 10 - caused two dams to break, inundating Libya's eastern city of Derna and killing thousands of people.
Friederike Otto is a Senior Lecturer at the Grantham Institute for Climate Change:
"I think what we consistently find no matter how we looked at the event, which data we used, or also which exact region we used, that we find an increase in the intensity... so while there is limitations on the data in terms of what the exact return time of the event and the exact magnitude, it doesn't affect very much the climate change signal."
The study added that building in flood plains, poor dam condition, long-lasting armed conflict and other local factors also played a role in the disaster.
It also warned that as climate change pushes weather to new extremes, it would remain risky to build homes on flood plains or to use substandard materials.
Meanwhile, climate change also caused up to a 40% increase in the amount of rain that fell in early September across the Mediterranean, causing floods that killed dozens in Greece, Bulgaria and Turkey.
