World emissions added heat \u201cequivalent to 1.7 billion atomic bombs to the ocean,\u201d a stark reminder of what\u2019s at stake, according to a new briefing amid the ongoing UN Ocean Conference (UNOC) in Nice centered around conservation and sustainable use of oceans and marine resources.<\/p>\n\n\n\n

Scientists say the \u201cworld added the energy equivalent of nearly two billion atom bombs such as \u201cLittle Boy\u201d to the ocean since the Paris Agreement was signed in 2015. The ocean heat content in 2025 (to a depth of 2000m) was about 104 zettajoules more than in 2015, equivalent to about 1.7 billion atom bombs (about five bombs per second)\u201d<\/p>\n\n\n\n

Collated by research consultancy Climate Trends, the data-backed snapshot of dramatic changes happening beneath the surface \u2014record sea temperatures, shrinking sea ice, and mass coral bleaching\u2014from publicly available data, has been reviewed by scientists. <\/p>\n\n\n\n

\u201cGlobal warming over the last 10 years equates to about 1.7 billion atomic bomb explosions, or if we divide this by the number of seconds in 10 years, it’s equivalent to about 5 atomic explosions worth of energy every single second,\u201d according to Dr Alex Sen Gupta from University of New South Wales, Sydney<\/p>\n\n\n\n

Climate change impacts on the ocean since 2015 include global sea ice hitting an all-time low this year, sea surface temperatures in 2024 smashing previous records, 84% of coral reef areas bleached in the biggest coral bleaching event ever.<\/p>\n\n\n\n

Gupta says \u201can extra 104 zettajoules entering and warming the climate system\u2014that\u2019s 104 thousand, million, million, million Joules of energy\u201d have been measured over the past decade<\/p>\n\n\n\n

\u201cClearly this is having an effect on the ocean \u2013it\u2019s causing sea level to rise, our ice systems to melt, and our atmosphere and oceans to warm. The last of these means increasing numbers of marine heatwaves, with the devastation that they bring. All this energy comes from humans putting more and more greenhouse gases into the atmosphere. Clearly this needs to stop,\u201d he adds<\/p>\n\n\n\n

It has been 10 years since the Paris Agreement. World leaders are currently in France along with NGOs, leaders of island states and scientists to dwell upon ocean action.<\/p>\n","protected":false},"excerpt":{"rendered":"
