The melting of polar ice due to global warming is causing a rise in the level of seas and oceans around the world. A rise that can be observed, mainly, from the 80s and 90s. NASA has shared an animation that shows, in the most graphic way possible, how the level of our oceans has grown over the last 30 years.
As can be seen in the video, the sea level has risen about 10 centimeters in the last 30 years. The animation shared by NASA exposes the impact of this increase in the eyes of someone traveling on a ship. More specifically through the perspective of a porthole on the wall of a boat.
Previous information published by NASA details the two main causes of sea level rise. On the one hand, the water added by the melting of ice caps and glaciers. On the other hand, the expansion of seawater as it warms. Both factors would be related to global warming.
Other significant data highlights that the rate of increase in ocean temperatures has doubled in the last 50 years and continues to grow to levels never seen before. This is due to the fact that the seas and oceans around the world are the ones that have absorbed up to 90% of the heat that humans have caused through carbon dioxide emissions.
Studies published in the journal Geosciences concluded that the sea level increased on the Spanish coasts at a rate of 1.6 millimeters per year from 1948 to 2019. As of 2019, the rate at which the sea level increases is 2 .8 millimeters, almost double.
