NASA-supported Study Confirms Importance of Southern Ocean in Absorbing Carbon Dioxide

By Sofie Bates

Observations from research aircraft show that the Southern Ocean absorbs much more carbon from the atmosphere than it releases, confirming it is a very strong carbon sink and an important buffer for some of the effects of human-caused greenhouse gas emissions, according to a new NASA-supported study.


Wildlife officials move to feed Florida’s starving manatees

A record manatee die-off in Florida this year has become so dire that federal officials are taking a once unthinkable step — feeding the wild marine mammals to help them survive the winter…


Photos show vast coral spawning event in Great Barrier Reef, giving divers hope for climate change recovery

By Ellen Francis Photo: Gabriel Guzman

Divers and scientists recorded the birth of billions of coral babies in Australia’s Great Barrier Reef on Tuesday night in a colorful show of life that they hope is a signal that the world’s biggest coral reef ecosystem can recover from climate change…


Albatrosses, known for monogamy, may be pushed to ‘divorce’ because of climate change, study finds

“It is a truth universally acknowledged,” Jane Austen wrote in the opening lines of “Pride and Prejudice,” “that a single man in possession of a good fortune, must be in want of a wife.” Social mores may have shifted since the early 19th century, but the maxim seems still to hold true for albatrosses, very large seabirds that live mostly in the Southern Hemisphere and are known as some of the world’s most reliably monogamous creatures.


Ready to Kelp: How the ‘Kelp Bill’ Unlocked a Potential Game Changer in the Climate Fight

By Scarlett Buckley

Kelp, a species of seaweed sometimes called “the rainforest of the sea,” could be a powerful weapon in the fight against climate change. Despite this, the commercial cultivation of kelp in Long Island, New York has long been illegal, until now.


Climate change killed 14% of the world’s coral reefs in a decade, study finds

Climate change is wiping out coral reefs and will kill more if oceans keep getting warmer, researchers warned on Tuesday in a new study that spanned much of the globe. The world already lost 14 percent of its coral between 2009 and 2018 — or what amounts to more than all the coral now living in Australia’s reefs — scientists with the Global Coral Reef Monitoring Network found.


Coral microbiome is key to surviving climate change, new study finds

The microbiomes of corals — which comprise bacteria, fungi and viruses — play an important role in the ability of corals to tolerate rising ocean temperatures, according to new research led by Penn State. The team also identified several genes within certain corals and the symbiotic photosynthetic algae that live inside their tissues that may play a role in their response to heat stress.


Earth is dimming due to climate change

Warming ocean waters have caused a drop in the brightness of the Earth, according to a new study. Researchers used decades of measurements of earthshine — the light reflected from Earth that illuminates the surface of the Moon — as well as satellite measurements to find that there has been a significant drop in Earth’s reflectance, or albedo, over the past two decades. The Earth is now reflecting about half a watt less light per square meter than it was 20 years ago, with most of the drop occurring in the last three years of earthshine data, according to the new study in the AGU journal Geophysical Research Letters, which publishes high-impact, short-format reports with immediate implications spanning all Earth and space sciences.


The Private Sector Takes a Stand for Oceans During Climate Week

By Roya Sabri

Climate Week in New York City started out with a clear message: The time for talking has passed; put your words into action. Climate action comes in many forms — policy change, investments in ecosystem restoration, clean technology innovation and much more. Oceans, increasingly under threat from melting glaciers and coral bleaching, are another big blue opportunity for action sitting right under our noses.


A Climate Solution Lies Deep Under the Ocean—But Accessing It Could Have Huge Environmental Costs

By Aryn Baker Photo: Spencer Lowell , Time

Scattered three miles deep along the floor of the central Pacific are trillions of black, misshapen nuggets that may just be the solution to an impending energy crisis. Similar in size and appearance to partially burned charcoal briquettes, the nuggets are called polymetallic nodules, and are an amalgamation of nickel, cobalt, manganese and other rare earth metals, formed through a complex biochemical process in which shark teeth and fish bones are encased by minerals accreted out of ocean waters over millions of years.
