"We have not had a clear understanding of what is driving this melting because the atmospheric forcing - the temperature at the surface - is not warm enough to cause such a melting," he added.

“我们对什么在推动这一冰融尚无明确的认识，因为大气促成的-表面温度-还没有热到足以导致如此的冰融，”他补充说。

Coastal fisherman know that when a flock of seagulls is circling and diving into the sea a school of bluefish is often driving bait fish towards the surface and the anglers hasten to cast their lines into the frothy water beneath the screeching birds.

While they may seem attractive theories on the surface, on closer inspection the research team found they could not be the driving force in the evolution of the lion's social lifestyle.
