Researchers say that seas are ascending and they are speeding up too. This is a sort of double whammy situation that has cropped up.
With global warming at an all-time high, seas are rising like never before. As ice melts and makes its way into the world’s waterways, this is a situation that is being faced by the coastal communities.

Yet now we know that there is more in store than just this. The oceanic waters are swelling as well since water expands under conditions of warmth. This much is obvious if data from NASA is to serve us well.
Seas are rising by 3.5 mm annually. That is 1.4 inches per ten years. However, if predictions are anything to go by, the full impact of these radical changes is the worst catastrophe that is thinkable by man.
Seas will not only ascend but speed up in the form of their currents and waves. That is because the great ice sheets in Greenland and Antarctica would lose their mass.
The only problem is that the scientists have not seen an acceleration of sea levels in their data records. This is a strange anomaly that needs rectification.
Observation of these phenomena began in 1992 via a satellite. This satellite has been overtaken by several other satellites since than. The scientists were left puzzled by the lack of such data in the satellite record.
However, a new article published in the open-access Nature journal Scientific Reports, shows how the experts have resolved this. Sea levels were artificially masked by various phenomena that took place.
A major factor was the cooling of the earth a year before the satellite started recording information. The cause of this was the 1991 eruption of Mount Pinatubo in the Philippines.
This filled the atmosphere with aerosol-like compounds that reflected the sunlight back towards the sun. The sea levels fell due to this thus lending validity to a naturally-skewed observational record.
Sea level speed is a very real phenomenon. It is a process that is still extant. Over 40 climate change models were examined in order to come up with this information.
The effects of Mount Pinatubo’s eruption have leveled off since than. So now we know better. The scientists may not have everything figured out just yet but they are getting there.
In fact, they are very close to a 24/7 monitoring of the indices of climate change. The speeding up of the seas spells trouble. Something must be done and fast. Otherwise we will have to face unpredictable circumstances in the future.
