"The Western Mediterranean Sea is heating up and getting saltier, a recent study finds." Every year the temperature of the deep layer of the Western Mediterranean increases by .oo36 degrees Fahrenheit. Also its salt levels increase a tiny bit and researchers are monitoring the sea. They claim the changes have to do with the effects of global warming. An increase in ocean salt suggests that there is an increase in the net evaporation of the water "the difference between evaporation and precipitation. "When evaporated water leaving the ocean is greater than water entering the ocean as precipitation that means overall less water staying in the sea with the same amount of salt. So the sea gets saltier." A higher evaporation rate can be because of a warmer ocean, but other main factors take a role too, like humidity and temperature of the atmosphere. "The top layer of the entire ocean has warmed significantly over the past 16 years, according to another study detailed in the May 20 issue of the journal Nature. From 1993 to 2008, the top 2,300 feet (700 meters) of the world's oceans warmed 0.64 watts per square meter."
This article pertains to Chapter 2 because in part of it, it talks about evaporation. In Chapter 2, we talked about many things including evaporation, condensation, and sublimation. Also, we talked about salt a little bit (especially during one of the labs). Finally, we also talked about saltwater and the Mediterranean is a salt sea.
