The ocean is warming at the rate of 5 Hiroshima shoots a second

The amount of heat pumped into the ocean by climate change is equivalent to five Hiroshima explosions per second.

According to scientists, that warns that Earth’s oceans reached record temperatures last year when global warming tightened its control over our planet.

An international team of climate enthusiasts analyzed sea temperature data from the 1950s to 2019.

They showed that last year, our oceans were 0.075C hotter than the 1981-2010 average.

It may not seem like much, but when considering the enormous scale of the Earth’s oceans, an amazing amount of heat equivalent to 228 sextillions (that is, 238 followed by 21 zeros) in value of Joules is required.

A scientist tried to quantify this by comparing it to the energy released by the nuclear bomb launched in Hiroshima, Japan, in 1945.

“The Hiroshima atomic bomb exploded with an energy of approximately 63 billion joules,” said Dr. Lijing Cheng of the Chinese Academy of Sciences in a press release.

“The amount of heat we have put into the world’s oceans in the last 25 years equals 3.6 billion Hiroshima atomic bomb explosions.”

In 2019, ocean warming was equivalent to “approximately five Hiroshima heat pumps, every second, day and night, 365 days a year,” study author Prof. John Abraham of the University of St. Thomas in Minnesota.

The team’s shock readings were taken from a network of more than 3,800 buoys spread across the planet.

Our oceans absorb 90 percent of the heat that humans add to the atmosphere, which makes them a good barometer for man-made climate change.

The researchers blamed global warming for the rise in sea temperature, which threatens to cause a catastrophic rise in sea level over the next century.

Ice melting in polar regions could lead to increases of up to 11 feet by 2100 if the oceans heat up to 4 ° C, according to some estimates.

This would displace hundreds of millions of their homes and create an emergency of “climate refugees.”

The clarification and management of such a catastrophe would put pressure on the US army so much. UU. Running the risk of collapse, a recent Pentagon report is heated.

And if that wasn’t enough, the rise in ocean temperature could even trigger massive storms across the planet.

“It makes hurricanes and typhoons more powerful and makes the rain more intense,” said Professor Abraham. “It puts our weather on steroids.”

He added that the energy we add to the ocean every second is equivalent to each person on Earth constantly pointing 100 hair dryers to the sea.

“The less technical term is: it is a ton of energy,” said Professor Abraham.

He added that although many damages were inevitable, there is still time to limit the effects of the climate crisis.

“This is really impacting us and it will be devastating,” said Professor Abraham.

“But the other part is that it is not too late to do something about it. The longer we delay, the more difficult and expensive it will be, but we can still take steps to make it less bad.”

The research was published in the journal Advances in Atmospheric Sciences.
