Southwest Pacific Hit By Unprecedented Marine Heat Waves In 2024: United Nations
Unprecedented heat waves in the Southwest Pacific affected more than 10% of the global ocean surface in 2024, damaging coral reefs and putting the region's last remaining tropical glacier at risk of extinction, the UN's weather body said on Thursday.

In Canada Lake, Robot Learns To Mine Without Disrupting Marine Life
Three robotic arms extended under the water in a Canadian lake, delicately selecting pebbles from the bed, before storing them back inside the machine. The robot was made by Impossible Metals, a company founded in California in 2020.

NASA’s SWOT Satellite Reveals Big Impact of Small Ocean Currents and Waves in n Marine Ecosystems
NASA’s SWOT satellite, in collaboration with CNES, reveals how submesoscale ocean features just a mile wide drive vital vertical circulation. These small currents transport heat, carbon, and nutrients, profoundly influencing marine ecosystems and climate systems. The mission’s high-resolution data is reshaping how scientists model ocean-atmosph...

NASA Reports 'Higher Than Expected' Sea Level Rise In 2024
NASA reports a higher-than-expected sea level rise in 2024, primarily due to thermal expansion of seawater, highlighting the urgent need to reduce greenhouse gas emissions to mitigate the devastating impacts of climate change.

Earth’s Oceans Were Once Green, And Scientists Say They Could Shift Color Again
Ancient green oceans may return due to climate change.

Record High Temperatures In 2024 Caused Ice Loss, Rise In Sea Levels: UN
The report said other factors could also have driven global temperature rises last year, including changes in the solar cycle, a massive volcanic eruption and a decrease in cooling aerosols.

Antarctic Ice Melt Weakens Strongest Ocean Current, Disrupting Global Circulation
The Antarctic Circumpolar Current, the planet’s most powerful ocean circulation system, could slow by 20 percent by 2050 due to melting Antarctic ice. Researchers suggest that the influx of fresh, cold water is disrupting convection, altering global ocean density. A weaker current may allow warm water to reach Antarctica, accelerating ice loss an...

Trump Job Cuts Threaten Climate Research, Public Safety, Warn Scientists
Climate scientist Tom Di Liberto had dreamed of working at the National Oceanic and Atmospheric Administration (NOAA) since college. After more than a decade as a contractor, he finally secured a full-time position nearly two years ago.

World’s Largest Iceberg A23a Grounds Near South Georgia, Raising Wildlife and Environmental Concerns
The world’s largest iceberg, A23a, has run aground near South Georgia, a key wildlife haven. Scientists are monitoring its impact on marine life, particularly on penguins and seals, as it could disrupt feeding routes. Some experts suggest the iceberg may also enhance ocean productivity by releasing nutrients. If it fragments, it may pose risks to...

Scientists Warn of Alarming Rise in Marine Heat Waves and Its Impact on Oceans
Reports indicate a sharp rise in marine heat waves, with 2023–2024 experiencing a 240% increase compared to past years. Scientists warn of devastating effects on marine life, including mass die-offs, coral reef degradation, and increased storm intensity. Coastal communities are at risk as extreme weather events linked to warming oceans become mor...

Earth's Strongest Ocean Current Is Slowing Down And It Could Have Devastating Consequences
The ocean current might slow down by around 20 per cent by 2050 in the "high carbon emissions scenario".

Seafloor Spreading Slowdown May Have Caused 26–32m Sea Level Drop Over Millions of Years
Between 15 million and 6 million years ago, ocean crust production declined by 35 percent, leading to deeper ocean basins. This geological shift is believed to have caused a sea level drop of 26–32 meters. Research suggests that heat transfer from the mantle to the ocean decreased by 8 percent, potentially altering ocean chemistry. Some studies i...

Earth's Orbit and Tilt Linked to Ice Age Cycles, Next One Delayed by Climate Change
Scientists have discovered a strong link between Earth's tilt and past ice ages, predicting the next glacial period would have started in 11,000 years. However, rising greenhouse gas emissions are disrupting these natural cycles. The research, based on ocean sediment data, supports the theory that Earth's obliquity governs ice expansion while prece...

New Study Reveals How Earth's Orbit Controls Ice Ages
A research team examined a million-year record of climate change, focusing on land-based ice sheets across the Northern Hemisphere and deep ocean temperatures.

Greenland's Ice Sheet Approaches Dangerous Tipping Point Amid Rapid Melting
Greenland’s massive ice sheet is losing ice at an accelerating rate, with scientists warning that a global temperature rise of just 2°C could trigger irreversible collapse. The loss of 230 gigatons of ice per year is the estimated threshold for this tipping point. If melting continues at current rates, sea levels could rise by approximately 7 me...
