Hold onto your chardonnay! A new study finds climate change is threatening the world's wine supply.

The international team of researchers say it boils down to grapes being sensitive to temperature change.

According to the researchers, if global temperatures rise by 3.6 percent in the next 80 years, wine regions could shrink.

Places like Italy, Australia, and Spain could be hardest hit.

Such a change would likely create a global wine shortage, which would drive prices up.
