Explanation:

All of the above are the characteristics of climate change.

The average temperatures of earth are rising as has been acknowledged by IPCC and other organisations as to be an outcome of Climate Change.

Due to rise in global temperatures the icecaps in high mountains as well as those at poles are melting as can be seen from receding Himalayan and Antarctica glaciers

Due to differential heating patterns precipitation patterns are changing as can be seen from rising events of floods draughts etc.

Finally Ocean warming is a surest sign of climate change
