As we know, climate change is affecting our planet a lot and every day more, but one of the most serious impacts it is causing is the melting of the poles.
Both the Arctic and the Antarctic contain 80% of the planet’s fresh water as well as 90% of the ice on the earth’s surface. For centuries, melting has been a natural process since it was determined by the season of the year, and although it has had periods of glaciation and melting, it has always been in constant balance.
Since then until now, there have been many changes and in particular in the last decades, the melting process has been increased due to the great amount of carbon dioxide that human actions release causing an increase in temperatures and the corresponding acceleration of the process. Specifically in the North Pole, the surface of polar ice has been reduced by 40% in a period of 40 years according to the U.S. climate agency. As far as Antarctica is concerned, the data obtained thanks to NASA are devastating, cataloguing the melting situation as irreversible.
This is the reality and we do not realize it. But the consequences go beyond that, affecting the marine currents. The contribution of the large amount of melt water to the ocean mass will thus raise the sea level and cause an ecosystem imbalance that is very difficult to repair… and although I have used future verbs, it is a reality that is already happening today.
The most threatened species.
The most harmed in this process are the species that live in these habitats because they depend on the ice to survive, most of them being in danger of extinction. Some of these species are:
The polar bear, whose scientific name is ‘Ursus Maritimus’ that lives in the North Pole and is in a vulnerable state in the Red List of species in danger of extinction.
The penguin, in particular the Emperor and Humboldt Penguins that live in Antarctica, and the Galapagos Penguin that live in the Galapagos Islands, among others.
The Arctic fox, whose scientific name is ‘Alopex Lagopus’ that lives in the North Pole and although they are not in the official lists of endangered species, they are part of the list of threatened species offered by the Center for Biological Diversity.
The Pacific walrus that inhabits exclusively the Arctic seas and is endangered by oil and gas exploration that pollute the oceans in its habitat.
Simulation on the meltdown.
According to a simulation carried out by researchers from the University of Victoria in Wellington, they have shown that the fastest rise in sea level will occur between 2065 and 2075 creating a complex feedback loop causing climate chaos.
Although we are talking about a specific simulation or model (of the different ones analyzed), what is indisputable in all of them is that the effects of climate change are impacting on the polar areas, with serious consequences for the entire planet.
