According to recent research in the journal Proceedings of the National Academy of Sciences, the world’s oceans are absorbing 90% of the excess energy caused by greenhouse gas emissions emitted by human activities. This means that global warming is making the world’s oceans warmer, causing sea levels to rise worldwide.

The Guardian’s science team concluded that global warming has heated the oceans by the equivalent of one atomic bomb explosion per second, for the past 150 years. The study took the combined measurements of ocean temperatures since 1871 across the globe and ran the data through the latest computer models of ocean circulation patters to find out where all that heat has gone. The technique, developed by researcher Samar Khatiwala, uses blunt force mathematics to analyse global ocean warming down to the seabed. This shows that melting ice caps are not the only cause of rising sea levels.
