The report makes clear that to protect the ocean, we must first reduce our dependence on fossil fuels. But we must also reduce ocean stress, caused by overfishing and pollution, so the ocean is healthy enough to weather the changes already underway.
“The bottom line is that we need the ocean. And right now, the ocean needs us,” said Julie Packard, executive director of the Aquarium. “It’s not too late to take courageous climate action and safeguard the ocean from further damage.”
In a study published Wednesday in the journal PLOS ONE, a group of scientists from various state and federal agencies, universities and bird rescue organizations documented the die-off and concluded from the data that it was caused by a record-breaking ocean heat wave in 2014 through 2016 that triggered systemic changes throughout the ocean ecosystem.
This loss of oxygen in the ocean is significant enough to affect the planetary cycling of elements such as nitrogen and phosphorous which are, “essential for life on Earth,” Dr. Laffoley said.
As the amount of atmospheric carbon dioxide continues to rise, our oceans are playing an increasingly important role in absorbing some of this excess. In fact, it was reported recently that the global ocean annually draws down about a third… Read More ›

Although Arctic-wide warming during the 20th century is well documented, little is known about the response of sea-ice to abrupt warming and it is unclear when the sea-ice decline started. Data coverage in this region is highly restricted, with observation-based satellite data only available since the 1970s, too short to accurately calibrate climate models.
“We were alarmed to find that diatoms were so negatively affected, with some species likely to have diminished silica production before the end of this century,” says Dr Petrou.
