The last three decades had been a quite challenging phase for our planet. As our globe is getting hotter it is having a significant impact on the marine world resulting in the rising sea levels, melting of polar ice sheets and abrupt climatic conditions.
Oceans are considered as an essential component for maintaining the earth’s ecological balance and sustainable development. As the global temperature is constantly on the rise due to huge emission of greenhouse gases and other human induced activity,it is having a detrimental impact on our seas and oceans. The effects of global warming is having a far reaching impact on the oceanic ecosystem that is leading to growing acidification risking the future of marine lives and coastal communities. The mighty oceans plays a pivotal role in moderating our planet’s climate by absorbing excess heat energy of the planet and transmit it evenly across the globe through oceanic currents.
Our oceans are vulnerable to serious consequences resulting from water pollution and greenhouse gases. As mentioned earlier, the oceans act as a huge heat sponge that is making its surface level warmer due to the excess absorption of greenhouse gases. This in turn is melting the polar ice caps and mountain glaciers leading to an alarming rise in the sea level. This phenomenon has already engulfed many small islands and coastal regions across the globe. Not only this, the warmer surface temperature of the earth is also hampering the lives of marine organisms and species, when they find it difficult to survive and adapt according to major temperature shift. The effects of global warming has lead to the increase in marine acidification endangering the coral reefs through deadly bleaching process making them vulnerable to gradual disease, damage and extinction. The Great Barrier Reefs of Australia is experiencing the adverse consequences of ocean acidification due to global warming and is directly responsible for damaging a vast portion of oceanic ecosystem.
The excess influx of toxic substances like industrial waste and accumulation of plastics in the oceans is endangering the lives of marine creature including the microorganisms and sea planktons. These sea planktons are the major food source of fishes and other sea creature that thrives well in the cold water currents. As the oceanic surface is getting warmer due to the effects of global warming, the phenomenon is disrupting the growth of phytoplankton threatening the marine lifecycle. In this potential climatic condition, the oceans that is the only source of daily livelihood for most people is facing huge dearth of marine resource.
The adversities of global warming and climate change is having a destructive impact on the oceanic ecosystem and the communities depend on them. The melting polar ice is not only elevating the sea levels but is also having a detrimental effect on the polar bears, sea lions and seals. If the harmful effect of global warming reaches an uncontrollable level, it will definitely cause the sea level to rise at an alarming rate leading to deluge, infrastructural damage and other severe natural calamities.
The one and only solution to save our oceans is to put a check on the emission of greenhouse gases and other harmful human induced activities. There is an urgent need of immediate action at national and international levels.
