Climate change

Direct impacts

 - relates to temperature

 - can lead to extreme weather such as storms or floods 

 - as temperatures rise glaciers melt which increases the amount of fresh water in the oceans

 - makes water less salty and less dense

 - can affect ocean currents that distribute heat

 - temperatures increase in some areas and decrease in others

 - damages food webs, some organisms cant survive with and increase or a decrease in temp.

Warmer waters - direct

 - plankton that feed on fish become less productive in warmer waters

 - warmer surface water mixes with nutrient rich colder water from below

 - fewer nutrients mean less plankton which means less
