John Cigliano, a professor of biology at Cedar Crest College, explained the impacts of climate change and ocean acidification to a crowd gathered Saturday at Payrow Plaza in Bethlehem.
Oceans absorb carbon dioxide in the atmosphere and their pH has dropped, affecting ocean organisms such as mollusks and corals, Cigliano said. That’s bad news for seafood lovers, represents a substantial loss to the fishing industry and means the world’s coral reefs will be gone by mid-century, he said.
But, Cigliano said, the tide is not completely out. He encouraged the crowd — who gathered as part of the nationwide March for Science — to decrease emissions, vote for politicians who understand those issues or run for office themselves.
