Sea Level Rise

WHAT IS SEA LEVEL RISE?

Global warming causes an increase in the level of the Earth's oceans, which is known as sea-level rise. This happens due to the burning of fossil fuels which releases heat-trapping gases in the atmosphere. Now knowing that heat is trapped in, it is obvious to know that the Earth’s oceans absorb the heat causing it to be warmer and expand. As a result, global ocean levels are rising.

WHAT’S THE EFFECT OF THIS?

It is affecting coastal areas all over the world, even a small increase. 

What are they?

  • It can cause destructive erosion

  • Wetland flooding

  • Aquifer

  • Agricultural soil contamination with salt

  • Birds, fish, and plants will lose their habitat

  • Threatens historical sites

There are many effects of this case. Local governments are spending a lot to defend against these effects of the rising sea level.

WHAT ARE THE IMPACT EXAMPLES?

We have to know some examples of the rising sea level impact. 

  1. Eustatic sea-level rise

Eustatic sea-level changes are global sea-level changes. It is related to changes in the water volume in the sea or ocean. The melting of glaciers and the thermal expansion of the water are examples of eustatic sea rise.

  1. Relative sea level rise

Relative sea level changes are global sea level changes too. But it is related to changes of the height of the ocean (rises or falls) and related to the subsidence of land. The example from these impacts is expansion of the ocean water volume due to decrease of water density with increasing temperature.

HOW TO PREVENT SEA-LEVEL RISE?

It is also incredibly important that we prevent sea-level rise from occurring. These are three basic things we can do to keep the ocean levels from rising:

  1. Plant more plants and save trees

Planting plants can contribute to the purification of the air and the absorption of rainwater, as well as the preservation of trees. Reducing the number of tissues and paper you use is a smart method to save trees from being cut down.

  1. Reducing energy use

Reducing energy use can start from turning off electricity-generated appliances at your house, such as lights & air conditioners when they are not in use. 

  1. Leave the car at home

One of the leading causes of carbon dioxide emissions is vehicles such as cars and motors. This is why we should lessen our reliance on them. Instead, we can walk, ride bikes, or take public transportation instead of driving.
