Answer:
They are caused by an increase in global temperatures
Explanation:
Global warming will cause a change in the weather patterns of a region – called climate change. A place could experience extreme weather such as increased dryness or wetness. This is mainly due to takeup of this heat by the oceans hence influencing global currents.
As the oceans become warmer, they are able to absorb more carbon dioxide from the atmosphere. This causes these water to have a higher acidity than normal because of the formation of carbonic acid.
