I think it's worth noting that you would never forage/collect seaweed that's been washed up on the shore, since
1. you don't know how far along it is in terms of decomposing
2. The water quality of where it grew
So I am not sure this is a valid argument unless you were trying to imply that clearly seaweed is still growing. But one point in time says nothing about a possible trend
While the oceans are warming, well, you're right and wrong. The amount of seaweed has been increasing, but it has nothing to do with warming oceans.[1]
