In March, Australia’s Great Barrier Reef suffered its most widespread bleaching event to date. Sixty percent of the reef underwent moderate to severe bleaching, and some corals may never recover.…
1. Climate change and oceans Climate change impacts on land made almost daily headlines this year: fires, floods, more extreme storms. Equally intense effects are being realized in our seas.…
As humans continue to emit record levels of carbon dioxide, we are putting marine habitats at risk. One consequence of these emissions, ocean acidification, is a serious threat to many…
PALAWAN, Philippines — Twenty years ago, people in this fishing village in the municipality of Quezon, on the Philippine island of Palawan, would just walk to the shore, throw a…
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…
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…
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.…
Some types of coral reef islands could potentially grow as a result of climate change-driven sea level rise, according to a recent study, which suggests that all of these islands…
Prior to the back-to-back bleaching events that hit the Great Barrier Reef in 2016 and 2017, the UNESCO World Heritage Site had suffered two other bouts of extensive bleaching in…
As oceans become more acidic, fish struggle to smell their food and predators, a new study has found. Much of the carbon dioxide in the atmosphere is absorbed by oceans.…
A more acidic ocean under climate change threatens to reconfigure entire ecosystems by advantaging some fish species to the detriment of others, a new study has found. The research is…
Even if all the world’s nations fully cooperated to reduce carbon emissions and limit climate change, elevated carbon dioxide levels will continue to harm our oceans in the coming decades.…
Marine fisheries have been estimated to support the livelihoods of 10 to 12 percent of the world’s population and generate an average of $100 billion in revenue every year. But…
n Wednesday of last week, Ecuador began pumping its first crude oil from the Ishpingo-Tambococha-Tiputini (ITT) block in Yasuní National Park, believed to be one, if not the most, biodiverse…
Global warming is changing Earth’s oceans and those impacts will last for decades even if we rein in greenhouse gas emissions from human activities, according to new research. A report…
cientists have long argued that restoring forests on land could mitigate global climate change, but what about restoring forests in the sea? Not forests made up of trees, of course,…
New research shows how soil carbon could be the key to protecting endangered species and reining in global emissions of greenhouse gases at the same time. Worldwide, we’re spending less…
Douglas McCauley began his career as a fisherman but later transitioned to marine science. He now serves as an Assistant Professor at the University of California, Santa Barbara and a Sloan…
New research suggests methane deposits that have been frozen in the seabed off the coasts of Oregon and Washington for thousands of years might have begun to melt and bubble…
Ocean acidification is troubling for most marine creatures. But some corals may have built-in protection mechanisms that could help them cope with changing ocean chemistry, a new study published this…
Scientists collected water samples to measure ocean acidification in the Bering, Chukchi, and Beaufort seas on two research cruises aboard the US Coast Guard cutter Healy. Photo credit: Jeremy Mathis…
As atmospheric CO2 levels rise, so too do those in the sea, leading to ocean acidification that outpaces that of any other time in tens of millions of years. Some…

If nothing done, extinction levels in the ocean could soon resemble those on land Bluefin tuna. Although most bluefin tuna species have been decimated by overfishing, they are still caught.…
The concentration of carbon dioxide in the atmosphere made the biggest jump last year since 1984, according to the World Meteorological Organization's (WMO) Greenhouse Gas Bulletin, raising alarm bells about…
The U.S. Midwest and Northeast experienced one of the coldest, snowiest winters on record this past season. This might seem contrary to warming trends forecast by climate scientists, but a…
It could be the plot of a horror movie: humans wake up one day to discover that chemical changes in the atmosphere are dissolving away parts of their bodies. But…
It's not just melting glaciers and bizarrely-early Springs anymore; climate change is impacting every facet of human civilization from our ability to grow enough crops to our ability to get…
Palau's Rock Islands. Courtesy of Google Earth. Scientists have discovered a small island bay in the Pacific which could serve as a peephole into the future of the ocean. Palau's…
An assessment of ocean acidification, presented at the UN Climate Change Conference in Warsaw in November 2013, starkly concluded that acidity is on track to rise 170 percent by the…
