Wave Theory
Introduction
Greenhouse gases, released by human activity into the atmosphere, are causing extreme weather events like killer heat waves, floods and storms by interfering with global air-flow patterns. Giant atmospheric waves blow at high altitude around Earth and keep the climate consistent by bringing warm air north from the tropics and cold air south from the Arctic. During recent extreme weather events these waves almost froze in their tracks for weeks due to the presence of greenhouse gases in the atmosphere. This made the extreme weather event persist and escalate for several days and months.
