Though some analysis point that there are no benefits to jelly fish. http://aslo.org/lo/toc/vol_53/issue_5/2040.pdf http://aslo.org/lo/toc/vol_53/issue_5/2040.pdf Generally, from what I've heard, the global warming is already straining the metabolisms of the existing sea creatures to a breaking point. Problem is we need to a super sharp CO2 reduction right now, to just keep the climate as it is now (i.e. patterns of extreme weather) and hope to restore balance within 50 years. This is ofc based on simulation so God knows, how accurate it is...
