A video shows how sea level has increased since 1993

The elevation of sea level is one of the most visible. Furthermore, worrying consequences of climate change. However. However, faced with the multitude of figures and predictions, it is sometimes difficult to concretely measure the extent of this phenomenon. For example, This is where a recent visualization of NASA comes in. However, which, thanks to satellite data accumulated for almost three decades, offers us a clear and striking perspective on the evolution of our oceans.

Changing sea level from 1993 – Video shows how sea level

We owe this short video to the Scientific Visualization Studio (SVS) of NASA. Therefore, Located at the Goddard Space Flight Center. Meanwhile, in the United States, this specialized unit is based on advanced visualization, modeling and animation techniques so as to make scientific concepts complex more accessible to the general public. Nevertheless, To do this. Moreover, the studio collaborates with NASA researchers to video shows how sea level interpret the data collected by satellites, space probes and other scientific instruments.

This video documents sea level change from 1993. It is indeed since this period that satellites reliably have changed sea level change.

Between the early 90s and the year 2022, the world’s average level of the sea would have increased by 9.85 centimeters. It might seem little, but NASA says this elevation is ” unprecedented in the last 2,500 years and more« .

Origins of sea level elevation

The origin of this elevation is none other than climate change of anthropogenic origin (linked to human activities) which acts in several ways. On the one hand, we know that the glacial caps that lose ice due to the increase in temperatures. This is particularly the case in Antarctica. the largest glacial cap in the world, where most of the cast iron occurs at the level video shows how sea level of its western part. This is also the case in Greenland which houses the second largest ice cap in the world.

On the other hand, the glaciers of mountainous regions around the world, such as the Alps, the Himalayas and the Andes, also lose ice. Again, this melting contributes to the elevation of sea level.

Finally, warming water is expanding more and occupies a larger volume.

Multiple consequences

It goes without saying that an increase in the too large sea level can have many harmful consequences. Coastal regions and low areas are particularly vulnerable to floods that can damage infrastructure and dwellings. Consequently, the populations concerned can be forced to move, which can lead to social and economic disturbances.

Naturally, the loss of coastal habitats such as marshes, mangroves and reefs is also harmful for biodiversity.

The flooding of agricultural land can video shows how sea level also lead to the salinization of soils and therefore the decrease in yields, which has repercussions on food security and the economy.

At sea, the increase in the volume of water in the oceans due to the melting of ice and thermal expansion can also modify the distribution of water masses by modifying the temperature and salinity gradients in the oceans. This can lead to changes in currents and therefore on the redistribution of heat and nutrients through the oceans.

In conclusion. the visualization proposed by NASA highlights the tangible and worrying reality of elevation of sea level, a phenomenon with potentially devastating consequences for our planet. The data collected show a significant increase since the 1990s. mainly due to the effects of climate change induced by human activities. The melting of glacial caps, mountain glaciers and thermal expansion of ocean waters are the main engines of this elevation.

Faced video shows how sea level with this threat, it is imperative to become aware of the risks and to implement adaptation and mitigation measures. The protection of coastal regions. Additionally, the preservation of natural habitats, and the reduction of greenhouse gas emissions are all challenges that we must face collectively. Awareness efforts. such as those made by the NASA Studio Visualization Scientific Studio, play a crucial role in making these complex issues more accessible and encouraging action. We now have the information. tools necessary to act; It only remains for us to use them in a judicious way to protect our future and that of future generations.
