Multiple evidence have been deciphered by now which, signify that climate change has transformed topography of the entire Arctic Ocean. The warming temperatures are leading the Arctic region to mutate as it is going through many transformations including more intense wildfires, melting ice, dissolving permafrost and changing ocean circulation.
Recent reports have stated that all these changes will become more prevalent and prominent in the near future as the impact of global warming will amplify in the near future. Adhering the same, before we put detailed emphasis on the changing environment of the Arctic Ocean, let us know some basic facts on global warming. With the amount of industrial pollution and other anthropogenic activities soaring up high, the atmospheric concentration of greenhouse gases is also increasing. Thus, the capacity of the Earth’s surface has increased drastically to trap the sun’s heat because of which, the average temperature across the globe is rising.
Now, after drawing an overview on definition of global warming and what it is all about, here’s what you need to know about the evolving signs of topographical and environmental changes of the Arctic Ocean.
Sea ice is dissipating fast and could be completely ‘a gone thing’ by the 2030s as expected. Evidence shows that the ice is disappearing in all the seasons with rapid shrinkage mostly during the summer months. Old ice, that has particularly laid the formation of ice bedrock for decades has also been declining precipitously.
The total permafrost cover is becoming narrower. Arctic soil holds around 50% of the total amount of carbon present in soil of the world. Due to the rising temperature, permafrost has been melting fast, as a result of which, a huge amount of carbon is being released into the atmosphere. Melting permafrost has also posed an issue for the various communities prevailing in the Arctic, which was being built previously on solid ground.
Land ice is vanishing fast, sea levels are raising and altering ocean circulation. The most significant impact of climate change is melting of land ice from the massive ice sheets of Greenland. It is known to be the biggest driver of sea level rise which, has been melting down fast since 2011.
These striking changes are the omen of what the future has in store for our planet, which, is certainly thought-provoking. Some of these have become irrevocable by now. Though, with the need to prevent the temperatures to rise up, many sincere, result-driven initiatives have come into the picture, but, how far we will be able to derive fruitful results from it is a serious question to think about.
