Climate change is the average change in conditions of temperature, rainfall over a long period of time. Rise in sea levels, melting of glaciers are some of its causes.

The ocean has absorbed much of this increased heat, with the top 100 meters of ocean showing warming of 0.33 degrees Celsius since 1969. Earth stores 90% of the extra energy in the ocean.
