What’s grosser than gross? Two words: Sea mucus. National Geographic has the scoop on marine mucilages, “jello-like sheets of disease-carrying mucus” that are spreading across the Mediterranean Sea.

A recent study found that sea-snot outbreaks increase when water temperatures rise, making this perhaps the most revolting evidence yet of the unexpected effects of climate change. It has some competition from the Arctic blob, a “fibrous, hairy” black goo that mysteriously appeared off Alaska this summer. It turned out to be an algae bloom, and one scientist suggested it had something to do with climate change. Global blob takeover—do you really need any more reason to get serious about global warming?
