In Egypt"s Red Sea, corals fade as oceans warm
Standing on a boat bobbing gently in the Red Sea, Egyptian diving instructor Mohamed Abdelaziz looks on as tourists snorkel amid the brilliantly coloured corals, a natural wonder now under threat from climate change......»»

Emergency atmospheric geoengineering wouldn"t save the oceans
Climate change is heating the oceans, altering currents and circulation patterns responsible for regulating climate on a global scale. If temperatures dropped, some of that damage could theoretically be undone......»»
Building bionic jellyfish for ocean exploration
Jellyfish can't do much besides swim, sting, eat, and breed. They don't even have brains. Yet, these simple creatures can easily journey to the depths of the oceans in a way that humans, despite all our sophistication, cannot......»»
The importance of critical minerals should not condone their extraction at all costs, says researcher
Global warming is real and climate change is worsening day-by-day with raging forest fires, unseasonably warm winters and flooding disasters taking place across Canada. Meanwhile, the carbon-zero transition required to move away from such a dire futu.....»»
Where does lightning strike? New maps pinpoint 36.8 million yearly ground strike points in unprecedented detail
It's been a warm day, maybe even a little humid, and the tall clouds in the distance remind you of cauliflower. You hear a sharp crack, like the sound of a batter hitting a home run, or a low rumble reminiscent of a truck driving down the highway. A.....»»
"Janitors" of the sea: Overharvested sea cucumbers play crucial role in protecting coral
Corals are foundational for ocean life. Known as the rainforests of the sea, they create habitats for 25% of all marine organisms, despite only covering less than 1% of the ocean's area......»»
Global dataset shows protecting fish doesn"t have to mean neglecting people
With fish stocks declining globally, more than 190 countries recently made a commitment to protect about a third of the world's oceans within "Marine Protected Areas," or MPAs by the year 2030. But these designated areas of the ocean where fishing is.....»»
A new theoretical development clarifies water"s electronic structure
There is no doubt that water is significant. Without it, life would never have begun, let alone continue today—not to mention its role in the environment itself, with oceans covering over 70% of Earth......»»
A Discarded Plan to Build Underwater Cities Will Give Coral Reefs New Life
A 1970s plan to grow underwater limestone objects has been repurposed as a way of regenerating the seabed, reestablishing corals, and stopping coastal erosion......»»
Earth"s early evolution: Fresh insights from rocks formed 3.5 billion years ago
Our Earth is around 4.5 billion years old. Way back in its earliest years, vast oceans dominated. There were frequent volcanic eruptions and, because there was no free oxygen in the atmosphere, there was no ozone layer. It was a dynamic and evolving.....»»
First reports of severe coral bleaching this summer as the Great Barrier Reef warms up
As ocean temperatures continue to warm over the Great Barrier Reef this summer, James Cook University scientists have reported areas of moderate to severe coral bleaching around the Keppel Islands offshore from Rockhampton......»»
Researchers find destruction of oceans" worth of water per month in Orion Nebula
An international team, including Western astrophysicists Els Peeters and Jan Cami, has found the destruction and re-formation of a large quantity of water in a planet-forming disk located at the heart of the Orion Nebula......»»
Satellites increasingly critical for monitoring ocean health
Playing a huge role in moderating the climate, oceans are fundamental to the functioning of our planet. Understanding more about how seawater temperatures are rising and how oceans are absorbing excess atmospheric carbon dioxide, as well as knock-on.....»»
Research shows how air pollution has offset expected increases in rainfall
We know that greenhouse gas emissions like carbon dioxide should increase rainfall. The emissions heat the atmosphere, causing a one-two punch: Warmer oceans make it easier for water to evaporate, and warmer air can hold more water vapor, meaning mor.....»»
A new tool can help protect California and Nevada communities from floods while preserving their water supply
At the dawn of the new year in 1997, the Truckee River transformed. The winter season had thus far been great for snow, but when a subtropical storm from near the Hawaiian Islands rolled in, it carried with it unseasonably warm rain. The warm rainfal.....»»
Why are fish getting smaller as waters warm? It"s not their gills, finds study
A collaborative team of scientists led by the University of Massachusetts Amherst recently found that there is no physiological evidence supporting a leading theory—which involves the surface area of fish gills—as to why many fish species are "sh.....»»
Nature"s checkup: Surveying biodiversity with environmental DNA sequencing
A thousand kilometers south of Tokyo, far into the largest ocean on Earth, lies a chain of small, volcanic islands—the Ogasawara Islands. Nature has been able to develop on its own terms here, far from both humans and the warm Kuroshio current, whi.....»»
Artificial reefs help preserve coral reefs by shifting divers away from the natural ones, says study
Divers are essentially tourists who love coral reefs and invest a lot of time and effort in watching them. Unfortunately, divers also cause damage to corals, often unintentionally, by disturbing and resuspending sand, touching them, hitting them with.....»»
Examining viruses that can help "dial up" carbon capture in the sea
Armed with a catalog of hundreds of thousands of DNA and RNA virus species in the world's oceans, scientists are now zeroing in on the viruses most likely to combat climate change by helping trap carbon dioxide in seawater or, using similar technique.....»»
Skyrocketing ocean temperatures have scientists scratching their heads
Shattered temperature records have grim implications for hurricane season. Enlarge (credit: jay_zynism via Getty) For nearly a year now, a bizarre heating event has been unfolding across the world’s oceans. In March 20.....»»
