A very hot Arctic spring has caused sea ice volume to fall rapidly to a new record, putting 2019 in position to challenge 2012 for lowest ice volume and extent this September.
Though the trend can still change, Arctic sea ice extent could be on track for a record melt year, impacting the jet stream and bringing more extreme weather to the U.S. and world.
Life on this planet, in all its wide diversity, is disappearing more quickly now than it has at any time in human history, and some 1 million species of plants…
In our last Reefscape story, we explored the northern Marshall Islands in search of answers about the long-term effects of nuclear fallout on coral reefs. We visited Rongelap and Ailinginae…
An analysis of 33 years’ worth of data finds that ocean winds and wave heights are becoming more extreme worldwide, with the Southern Ocean seeing the largest increases. In order…
Sea ice melt is nearly two weeks ahead of past records for early April, while a new study finds that the Arctic system is trending away from its 20th century state into an unprecedented state.
Scientists have mapped out an enormous network of potential protected areas, covering more than one-third of the world's oceans, to conserve marine biodiversity threatened by overfishing, emerging deep-sea mining, plastic…
Research over the past few years has shown that ocean acidification impacts Atlantic cod at the earliest stages of their lives, while they are still eggs and larvae. Scientists hoped…
Coral reefs in protected areas that regulate fishing and pollution have declined to the same extent as reef systems in unprotected areas, according to recent research. The study, published in…
Though sea ice extent was up across much of the Arctic at winter maximum, the Bering Sea lost an ice area the size of Montana, and Greenland has been receiving winter rains.
A new marine protected area (MPA) has been founded in the Philippines within what are considered some of the most biologically diverse waters on Earth. The new MPA, which has…
Tallying up the toll of our individual roles in fueling climate change is a daunting task. To make decisions simpler, we rely on the sorts of trade-off behaviors and cognitive…
Blue whales in the northern Pacific Ocean use their memories to guide them to the best feeding spots, instead of seeking out the locations of shorter-term surges in prey, a…
According to independent analyses of the latest global temperature data by the U.S. National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration (NASA), 2018 was the fourth…
A mystery disease outbreak that has devastated more than 20 species of starfish along the western coast of North America since 2013 has claimed yet another victim: the sunflower sea…
Baby krill living around Antarctica are struggling to cope with rising sea temperatures, new research suggests. The study, published online Jan. 21 in the journal Nature Climate Change, shows that…
Global climate change is impacting Earth’s oceans in a number of ways, from higher water temperatures and rising sea levels to acidification and oxygen depletion. Now, scientists have reported another…
2017 currently holds the record for hottest ocean temperatures, but, according to a new study, 2018 is likely to take the top spot as hottest year on record for Earth’s…
New research by scientists at the United States’ University of Washington and Stanford University suggests that the most destructive mass extinction event in Earth’s ancient history was caused by global…
The devastation wrought by hurricanes and cyclones, persistent and growing threats in today’s changing climate, can ripple through communities dependent on harvesting food from the sea, a new study has…
Throughout the spring and summer of 2017, a “flash drought” developed quickly in the Northern Great Plains region of the United States, which encompasses the states of Montana and North…
After months of fasting as she traveled hundreds of kilometers across the ocean, a female loggerhead sea turtle hauls herself up onto the sand: the shoreline she has returned to…
1. The race is on to map the seafloor Is it true that we have explored the moon and Mars more thoroughly than the bottom of the ocean? Embarrassingly, yes.…
On a midsummer evening earlier this year, Tracy Pham was on a walk along Huntington Beach, California, an outing she usually made to photograph birds. This time, along the way,…
The Trump Administration announced today that it will issue five Incidental Harassment Authorizations (IHAs) for airgun blasting off the Atlantic coast. The US National Oceanic and Atmospheric Administration (NOAA) stated:…
When a vibrant coral reef teeming with life transforms into a barren skeleton in the tropical shallows — as a result of bleaching linked to climate change, for example —…
New research suggests that coral bleaching triggers rapid behavioral shifts in reef fish. Higher ocean temperatures caused by global warming are the leading cause of the mass bleaching events that…
NUSA DUA, Indonesia — Global participants in the fifth Our Ocean Conference have pledged the highest amount of funding yet for new initiatives and commitments on the protection of a…
New research finds that the mass bleaching event that led to the death of 30 percent of shallow-water corals on the Great Barrier Reef in 2016 also had a substantial…
On the morning of March 1, 1954, the United States tested its largest thermonuclear bomb over Bikini Atoll in the Marshall Islands. Code-named “Castle Bravo”, the explosion was more than…
