Arctic Sea Ice

One of the most well publicised effects of climate change is of course global warming. It makes many forms of life unsustainable on land and even supports outbreaks of brush fires. However it is not just the land that is being negatively affected by global warming.

The amount of sea ice in the oceans of the world have began to melt at an alarming rate. Analysis by the NSIDC has shown that in the year 2018 the amount of sea covered with at least 15% ice has decreased from 15 million km to around 10 million km. This shows an alarmingly fast melt trend that is likely to continue.

This is worrying for a number of reasons. There are many sea creatures that need to rely on ice caps in order to survive. These include arctic creatures such as penguins and polar bears. Some of these animals use the ice caps for mating rituals as well as to care for their young. Due to global warming these structures will disappear and this threatens the extinction of a number of species.

These developments have far reaching effects that even stretch to threatening human life as well. There are large populations of people throughout the world that live on the coast. In the coming years this sea ice will continue to melt and sea levels will rise steadily. As this happens more water will spill out onto coastal land and large amounts of it will be reclaimed by the sea.

This will mean that humans living on this land will be threatened by flooding and increased coastal erosion. It will also mean that there will be mass migration crisis as people are forced to move further in land to escape the flooding. For these reasons the melting of the Arctic sea ice has consequences for much of the planet.
