Research showing steeper increases in ocean heat is not exactly new. So what's up with all those headlines?

Credit: Getty ImagesMath can be scary, but if you’re in the market for some really terrifying mathematics, a major new study puts hard numbers to the rate at which oceans are heating up due to global warming. Hold on to your exponential functions.According to research published this week in the journal Proceedings of the National Academy of Sciences, the world’s oceans are absorbing around 90 percent of the excess energy caused by greenhouse gas emissions. That’s to say that the bulk of global warming is sinking into the world’s oceans, increasing temperatures and triggering sea level rise worldwide. The compiled estimates suggest that global warming of the oceans from 1871 to the present adds up to about 436 x 1021 Joules. Unless you speak math, that might not mean much, so researchers have provided some context. The excess heat absorbed by the oceans in that time frame is around 1,000 times the annual energy use of the entire population of Earth. For a more vivid analogy, the science team

A century and half of reconstructed ocean warming offers clues for the future

Over the past century, increased greenhouse gas emissions have given rise to an excess of energy in the Earth system. More than 90% of this excess energy has been absorbed by the ocean, leading ...
