Trenberth described the Earth as an interconnected system trying to equalize the imbalance caused by excess human heating.
"We expect more activity as the system: the atmosphere and ocean, try to get rid of the extra heat," said Trenberth. "Hurricanes play a major role in this: a role of such storms is to pump heat out of the oceans, into the atmosphere, and disperse it to where it can radiate to space."

"That's because one big storm can play the role of 4 or more smaller storms in moving heat" and striving for energy balance, said Trenberth.
