What is the climate of ths western region of the us?

In the western part of the US, the air is a lot more warm and nice because the water gives it a more mild climate than in the inland. 

Ansradar; im guessing here; good luck : )

When a lake, river or other aquatic  system  becomes  eutrophic, it can have serious negative effects on other organisms like fish, birds and even people.if an algal bloom is so bad that it causes wide-spread death  in  the  water, the organisms that die will all sink to the bottom and start to decompose.
