Hottest Ocean Temperature Recorded in 2018, This is Bad News


  • 2018 is the hottest year when it comes to rising ocean temperatures as compared to a baseline temperature from 1981-2010.
  • Warmer oceans have had devastating effects on life on earth, making sea levels rise, storms stronger and causing the loss of human life and property, death of the ocean’s coral reefs, and a decrease of the population of sea life.
  • Though the science and evidence of global warming are clear, not enough is being done to combat it.

Ocean temperatures have been steadily on the rise since the late 1950s. Last year, the hottest ever ocean temperature was recorded. The measurements are published in an article in the journal Advances in Atmospheric Sciences. The article’s head author Lijing Cheng worked with his colleagues from the Institute for Atmospheric Physics, China, as well as other researchers from around the world.

The rise in ocean temperatures is a direct result of the greenhouse gas emissions that come from human activities. More than 90% of the heat that comes from the greenhouse gasses are absorbed by oceans, so if you want an accurate picture of climate change, measure the warming of the oceans.

Though air temperatures are usually used in media to be used as evidence of global warming, these measurements can be very unpredictable.

The oceans have a temperature that has been the hottest on record for the past five years. Comparing ocean heat to a baseline taken from 1981-2010 figures shows a difference of 196,700,000,000,000,000,000,000 joules.

The current rate of the ocean’s increase in temperatures is comparable to five Hiroshima-size atomic bombs going off every second.

Ocean warming is undoubtedly proof of global warming that has had catastrophic effects. Since warmer water expands, sea levels have risen. Scientists estimate that the rise in sea level will reach around one meter by the end of the century. This would be enough to sink enough land worldwide to displace around 150 million people.

Storms have also become more powerful due to warmer waters. Hurricanes, downpours of rainfall, and flooding are becoming worse around the world.

Aside from affecting human life, ocean warming has also resulted in the bleaching of coral reefs. Continued warming will mean the loss of more of these reefs and a plunge in sea life population.

We cannot deny the evidence that global warming is real and has had damning effects on all life on earth. It’s an issue that many people are not taking seriously enough. Though some steps have been taken to fight global warming, it is not enough.
