Climate change is a hot topic today, with many consequences around the world. Climate change is, therefore, an unusual manifestation of the natural climate. One of the recent signs of climate change is the cyclone phenomenon that occurred this month in Mozambique and Zimbabwe. It shows that there is something abnormal in nature.

 

Another manifestation of climate change is the rise of the oceans, the main focus of my report. Indeed, an increase in sea level is accelerating. It is the primary conclusion of the study of a Franco-Swiss team led by Anny Cazenave, Laboratory for Geophysical Studies and Oceanography in Toulouse, and published in the latest edition of the Journal Geophysical Research Letters. This is the first to detect an acceleration in the rate of ocean rise since satellite observations began in 1993. This work suggests that the sea level rose between 2004 and 2015 by 25% to 30% faster than the sea level between 1993 and 2004. They make it possible to reconcile two types of observations: sea level rise measurements on the one hand, and continental glacier loss measurements on the other side. (Stephane Foucart, 2017).  Rising waters have been a known consequence of global warming for many years. It mainly affects island States or the Atoll States. An island state or Atoll State is an island concentrated in the Pacific Ocean or the Indian Ocean. More straightforwardly, it's land in the ocean, with people living there. It is the example of Seychelles, the Marshall Islands.

Solving the problem of rising sea levels, for example, means finding short and medium-term solutions for these islands and long-term solutions for the entire planet. 

In the short term and the medium term, it is a question of finding a solution or solutions for the populations of these reefs (Atoll States) condemned to disappear. These solutions are much more forms of adaptation to rising water. These forms of adaptation are limited to three options. The first option is to protect the habitats of these islands through infrastructure and the environment. It involves the construction of dikes (raised earth, stones, wood, etc. to contain the waters of a river, a stream, a lake, and counter the waves of the sea); also the protective walls and the construction of artificial floating islands adjusting to sea level. A case in point is the city of Venise in Italy that was constructed on water . In addition to the human building, it is possible to use nature or the environment to combat the rise of the sea. Indeed some islands use environmental strategies such as the relocation of mangroves. Here is one of the wonders of nature. Indeed, it is a fact of trees able to live in the warm, salty and shallow waters of the trophies. Thanks to its curved aerial roots anchored in the mud, mangroves can absorb 70 to 90% of the ocean currents thus limiting the effects of waves.

The second option is to raise the habitat, and the third option is to migrate within the state-Atoll or migrate squarely to another state. 

In the long run, all the states of the world will have to agree on reducing greenhouse gas emissions. That is to say, limit as much as possible atmospheric pollution in all its forms (modern form, transport-related form, etc. And on this point, the world has enough effort to provide for our planet to be saved. 

Here are a few, and among others, some solutions that are presented to humanity in the face of the rise of the oceans and giving us solutions for dealing with climate change.
