Reperfusion injury can occur after a crush injury. The myoglobin, creatine, potassium and phosphorus from destroyed muscle cells cause kidney damage. The potassium is really important as it is supposed to stay locked within cells and high levels can cause arrhythmias. For more info look up crush syndrome and reperfusion injury. This is all slightly different from hypothermia but may share some pathways if cells are destroyed.

It’s a bit odd to extrapolate to this level. It’s like thinking, yes, I can set one tree on fire and release energy, but look how crazy it is if all the trees in North America burn at once!!

And currents are also affected by the rotation of the Earth, temp differences, and salinity differences so they might not change dramatically.
