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...

Scientists Discover Declining Global Ocean Evaporation Amid Rising Temperatures
Recent research has revealed a decline in global ocean evaporation since 2008, challenging traditional climate models. Despite increasing sea surface temperatures, evaporation rates have decreased across two-thirds of the world's oceans. Scientists attribute this unexpected trend to reduced wind speeds, or "wind stilling," and shifts in atmospheric...

Ocean Warming Rate Quadruples Over Four Decades, Accelerating Climate Change
New research highlights a troubling acceleration in ocean warming, with the rate of temperature rise quadrupling since the 1980s. According to a study in Environmental Research Letters, ocean surface temperatures now rise at 0.27°C per decade, up from 0.06°C. This rapid warming, driven by greenhouse gases like CO2 and methane, is worsening Earth'...

New Study Uncovers Vital Ocean Processes for Carbon Storage and Climate Regulation
A new study has identified two crucial processes in preserving organic carbon beneath the ocean floor: sorption and molecular transformation. Conducted by scientists from the University of Manchester and the University of Leeds, the research highlights how these mechanisms keep carbon locked in sediments, preventing its release as carbon dioxide. A...

Humpback Whale’s Unprecedented 8,000-Mile Migration Shatters Records
A humpback whale has been tracked on an unprecedented 8,000-mile migration, breaking records for the longest documented journey between breeding grounds. Scientists suggest the movement might be due to climate change affecting food and mating behaviours. AI-driven photo tracking through HappyWhale.com played a key role in identifying the whale’s ...
