Correct.
Per excerpts from the linked article in the OP;

For decades, anthropologists, historians and scientists have thought the Eastern Settlement’s demise was due to the onset of the Little Ice Age, a period of exceptionally cold weather, particularly in the North Atlantic, that made agricultural life in Greenland untenable.
New research, led by the University of Massachusetts Amherst and published recently in
Science Advances, upends that old theory. It wasn’t dropping temperatures that helped drive the Norse from Greenland, but drought.

They discovered that while the temperature barely changed over that period what happened was the area became drier in Southern Greenland.
Norse farmers had to overwinter their livestock on stored fodder, and even in a good year the animals were often so weak that they had to be carried to the fields once the snow finally melted in the spring. Under conditions like that, the consequences of drought would have been severe. An extended drought, on top of other economic and social pressures, may have tipped the balance just enough to make the Eastern Settlement unsustainable.

The research team spent 3 years gathering sediment samples from a lake called Lake 578. There were Norse settlements close to this lake.
