Because of global warming, the ice that makes up parts of Greenland is melting allowing for the true geological forms of the island show through. A new island has been discovered off the coast of Greenland that was originally thought to be a part of the mainland. Ice connected the two parts of land until recently. The coasts of Greenland are changing so rapidly and it is believed that Greenland could be losing 80 cubic meters of ice per year.

Explorers are now traveling on this new terrain trying to map out the ever changing coastline. Airplanes will fly over them and drop supplies they need to survive in the artic climate. Airplanes are powered by electricity. To start the engine a spark ignites the engine and causes the motor to turn. This is a type of electrodynamics because the spark is caused by the charging of the metal that is in the charger. The metal is a conductor that allows charge to travel through it.
