Climate change may be culprit in Antarctic fish disease outbreak

Climate change might be behind an unusual disease outbreak among Antarctic fish. For about a decade, University of Oregon biologists John Postlethwait and Thomas Desvignes have been visiting the West Antarctic Peninsula. They study a unique group of fish that has adapted to the harsh polar environment. But on a 2018 field excursion, they noticed something especially strange: a large number of those fish were afflicted with grotesque skin tumors.

This study models the future losses in the fight to drive down respiratory-damaging, ground-level ozone if the regulations go away.
