Growing numbers of jellyfish linked to global warming Answered
The growing number of jellyfish in the oceans has scientists worried, as they say it is an indication of how badly the ocean is being treated. They are showing up in places where they have never been seen before, and this is being attributed to a number of causes, including global warming and overfishing of the jellie's natural predators.
I can personally attest to this one. I went to the beach and got stung by these little nasties. There must have been thousands and thousands of them swimming around. When they sting you, it HURTS. I had whip marks on my arms and legs for hours. Stupid jellyfish...
