World oceans heating as if 5 Hiroshima bombs are dropped every second: Scientists
A new study reveals that the world's oceans are now heating at the same rate as if five Hiroshima atomic bombs were dropped into the water every second.

A new study reveals that world's oceans are w heating at same rate as if five Hiroshima atomic bombs were dropped into water every second. According to scientists, 2019 was yet ar year of record-setting ocean warming as ocean temperatures reportedly reached highest ever recorded. An international team of 14 scientists reportedly examined data going back to 1950s and looked at temperatures from ocean surface to 2,000 meters deep.
According to study, oceans are warming at an increasing speed and while past dece has been warmest on record for global ocean temperatures, hottest five years ever recorded all came in last five. study furr also reveals that warming has accelerated rapidly.

Kevin Trenberth, a distinguished senior scientist in Climate Analysis Section at National Center for Atmospheric Research reportedly said that urd trend is relentless and most of warming is man-me climate change.

Lijing Cheng, study's le author furr said that ocean temperature was 0.075 degrees Celsius above 1981-2010 aver in 2019 and re are reasonable alternatives aside from human emissions of heat-trapping gases to explain such rapid heating. He later ded that amount of heat that people have put in world's oceans in past 25-years equals to 3.6 billion Hiroshima atom-bomb explosions.
Cheng also ded that oceans serve as a good indicator of real impact of climate change, but speed at which warming is taking place, it's equivalent to dropping roughly four Hiroshima bombs into oceans every second over past quarter of a century.

Trapped greenhouse gases
Scientists have also found hidden time bombs in form of large reservoirs of carbon dioxide and methane that are scattered all across ocean, under sea-floor. Frozen carbon dioxide and methane deposits that are present under sea are slowly dissolving as global temperature continues to rise due to climate change. With growing temperature of oceans, hydrate caps that contain CO2 and methane deposits melting oceans can turn into big carbon emitters inste.

According to Lowell Stott, a paleoceagrapher at University of Sourn California, if hydrate caps melt n an ermous volume of CO2 and methane will be released in atmosphere. This discovery of melting hydrate caps come right after scientists said that world is surpassing a number of climate tipping points, ocean temperature is reaching record highs.
