The current hiatus in terms of global climate change has been linked to a greater phenomenon of a change in climate than seen in previous historical trends. The globe was rising in temperature throughout the beginning of the 21st century, but has entered into a hiatus, a period where the CO2 levels continue to rise but the global temperature is remaining constant. It is predicted that temperatures will continue to rise once this hiatus passes. The main cause of this hiatus, known as planetary heat sink, is the concept that the ocean is absorbing more heat to offset the increasing amount of carbon dioxide in the atmosphere (see figure 1), and this explains why atmospheric temperatures are not changing (see figure 2).
