Hello!
The answer is: C)Warmer temperatures would cause more evaporation and more precipitation.
Why?
Warmer temperatures around bodies of water like oceans and most lakes will alterate the temperature of the water. A temperature increment will be traduced in more evaporated water, which can be translated into more precipitations.
It's a negative aspect, especially when we there are coastal communities, this climate alteration will translate in extreme flooding, affecting in a really bad and dangerous way the coastal communities, but flooding is not the only affectation, in fact, this will make the climate out of control, while some can experiment extreme flooding, others will experiment extreme droughts.
Have a nice day!
