~sIdE EffEcTs Of GloBaL WaRmInG~

Scientists have long stated that the main effect of global warming is the melting of the polar ice caps,resulting in a rise in sea levels. However ,as we observe the theory become a reality ,it is becoming apparent that this phenomenon also has multifarious secondary effects.

Fresh water from melting  ice caps flows into the sea reducing the concentration of salt in the water and thus the sea's density. Saline -dense water would normally sink to the sea bed and then travel to warmer equatorial regions. Concurrently,the warmer less densely saline water in warmer parts of the world would travel along the sea surface to the poles,where its salinity would increase and the water would consequently sink. However as the salinity of polar water decreases ,this ocean process slows down. This cycle is vital, however as it has an oxygenating effect on the water and also carries nutrient  from deeper water to the surface. Therefore any slowing down of the cycle may have dramatic consequences of sea life .



A second alarming discovery is that the sea itself has traditionally played a role in reducing global warming. Oceans hold within them a certain amount of carbon dioxide . As the temperature of the sea  rises ,so its capacity to hold carbon dioxide ,falls , thus the problem of global warming is further exacerbated . However ,there is a piece of good news to counter this,melting ice caps and lower saline levels enable the sea to hold more carbon dioxide ,so the problem could be offset to some extent.
