The temperature of the Earth increases, making the marine ecosystem strong

The oceans of the world will have to undergo dramatic changes in biodiversity, even though the United Nations has achieved the goal of limiting global temperature rise below 2 degrees Celsius.

The marine biology has strongly changed due to the rise of the Earth's temperature

The study was carried out by scientists at the French National Center for Scientific Research (CNRS) mainly by analyzing the effects on organisms living at depths of 200m above sea level. The most valuable in the ecosystem of mankind.

According to the study, if it is not prevented urgently, climate change will lead to a major fluctuation in marine biodiversity on a global scale.

When the Earth heats up, marine species, mainly fish, need cooler water environments to migrate or become extinct, and instead are adaptive organisms warmer seas.

In the most optimistic scenario, if the average temperature increases by 1 degree C, there will only be minor changes in biodiversity by 2100.

However, if the current trend continues, the Earth's temperature will increase by 4.8 degrees Celsius only in this 21st century, biodiversity will have the biggest change in the past 3 million years.

According to scientists, it is more worrisome that even though the UN member states have reached the goal of limiting global warming at 2 degrees Celsius, the degree of biodiversity change happening in 2100 is still three times higher than the change in the past half century.

Scientists warn that the higher the temperature of the Earth, the greater the variation in biodiversity, especially for marine biodiversity.

Research by scientists at CNRS is the first study of biodiversity changes in the three epochs of Earth's formation and development.

First, the warm period took place in the mid- century Plioxen 3 million years ago. Subsequently, the Earth experienced a colder period, culminating in the Ice Age 26,500-20,000 years ago.

The third phase is in the period from 1960-2013, that is when the situation of the Earth heating up due to human impact becomes more serious./.
