What’s behind this rapid increase isn’t totally clear yet. “These temperatures just rocketed up, people haven’t had a chance to puzzle it all out,” Johnson said. Some scientists are concerned the scale of these new records could mark the start of an alarming trend. Others say record-breaking temperatures like these are always concerning but to be expected given the human-caused climate crisis. All agree the consequences are likely to be significant. Warmer oceans bleach coral, kill marine life, increase sea level rise and make the ocean less efficient at absorbing planet-warming pollution – the warmer oceans get, the more the planet will heat.
Arctic Ocean acidifying up to four times faster than any other sea on Earth
What may be the broadest and longest study to date has found Canada's Arctic Ocean is growing more acidic up to four times faster than any other sea on the planet. The acidification, linked to the loss of sea ice, will have unknown repercussions for the life in those waters, said Wei-Jun Cai, an oceanographer at the University of Delaware and co-author of the study in the journal Science.
