Europol-led sting cripples transatlantic cocaine routes

Europol-led sting cripples transatlantic cocaine routes

A two‑week international operation coordinated by Europol disrupted a major cocaine trafficking network moving drugs from Latin America to Europe. Authorities seized over 12 tons of cocaine and about 9.5 tons of hashish, intercepted eight vessels, and arrested 54 people. The effort highlights evolving, offshore multi‑stage transfers in the Atlantic to evade major ports, with focus on the area between the Canary Islands and the Azores, termed the so‑called cocaine highway.

Spain Seizes What May Be Record Cocaine Haul From Atlantic Shipment

Spain's Civil Guard intercepted a ship in international waters near the Canary Islands, unveiling an estimated 35–40 tons of cocaine—potentially the largest haul in Spain's history—with about 20 arrests as the investigation proceeds; authorities suspect the cargo was meant for offloading to smaller vessels for distribution in Europe, underscoring international trafficking networks.

Ancient volcanic bursts reveal AMOC’s vulnerability to climate disturbance

Ancient volcanic bursts reveal AMOC’s vulnerability to climate disturbance

New research links the Younger Dryas cooling (12,900–11,700 years ago) to a cluster of volcanic eruptions that disrupted the Atlantic Meridional Overturning Circulation, showing the AMOC’s sensitivity to disturbances; today, scientists warn that the AMOC could weaken or collapse due to human-caused CO2, but volcanic activity is not the immediate threat, highlighting how rapid climate shifts could arise if this ocean conveyor belt slows.

Atlantic circulation on the brink: new study suggests AMOC weakening near tipping point

Atlantic circulation on the brink: new study suggests AMOC weakening near tipping point

A Science Advances study estimates the Atlantic Meridional Overturning Circulation (AMOC) could slow about 50% by 2100—a weakening stronger than some models predicted—potentially cooling northern Europe and altering rainfall in various regions. The researchers argue that including sea surface temperature and salinity improves forecasts, but experts caution there is substantial uncertainty in the magnitude and timing of the slowdown. While a catastrophic “collapse” is unlikely in the near term, the paper underscores a real risk of crossing a tipping point, prompting calls for nations to prepare for significant climate effects.

Atlantic Conveyor Under Strain: New Studies Warn AMOC Could Collapse Soon

Atlantic Conveyor Under Strain: New Studies Warn AMOC Could Collapse Soon

Two new studies warn that the Atlantic Meridional Overturning Circulation (AMOC), a core ocean-current system that transports heat around the globe, is weakening and could be approaching collapse sooner than many models predict. A Science Advances study suggests a slowdown of more than 50% by century’s end, greater than the average model projection, raising the possibility of a tipping point; separate real-world data from moorings on the western North Atlantic show AMOC weakening at four latitudes since 2004. If AMOC collapses, Europe could face harsher winters, the U.S. East Coast could see higher sea levels, and droughts could intensify across parts of Africa, with Greenland meltwater potentially accelerating the trend. The findings underscore the urgency of improving climate models and understanding oceanic responses to warming.

Atlantic Conveyor Could Slow by Half by 2100, New Study Finds

A new Science Advances study using observational constraints projects the Atlantic Meridional Overturning Circulation could weaken about 50% by 2100 (with 90% probability), a pace and magnitude stronger than many climate models, raising concerns it could approach a tipping point with widespread climatic consequences such as sea-level rise along coastlines and shifts in storms and rainfall.

Mantle Plume and Transient Boundary Carved the Atlantic's King's Trough

Mantle Plume and Transient Boundary Carved the Atlantic's King's Trough

New mapping and rock analyses show the 500‑km King’s Trough off Portugal formed 37–24 million years ago where a temporary plate boundary intersected a mantle plume, causing intense fracturing and basin formation but stopping short of a full seafloor‑spreading ridge; the plume likely connects to the Azores system, offering a living example of how such underwater canyons develop under tectonic and thermal forces.

Crossing the Atlantic in a Three-Foot Microyacht: A Solar-Powered Ocean Stunt

Adventurer Andrew Bedwell aims to sail 1,900 miles from Newfoundland to Ireland in a 3-foot-long boat called Big C V2, marketed as the world’s smallest boat. The microyacht has no luxury amenities, just a domed cover and a footwell, but can carry about 550 kg and uses solar panels to power navigation electronics with two Victron batteries, plus a handheld chartplotter and phone-based navigation. He is documenting the build and journey on Instagram, attempting a dramatic ultra-small-ocean crossing.

Overnight Rescue Saves Rower after Capsize in 3,000-Mile Atlantic Race

The U.S. Coast Guard and the tanker Horten rescued Benoit Bourguet, a 47-year-old Belgian rower, after his single-man boat City of Liverpool capsized from rogue waves during the World's Toughest Row Race about 1,275 miles east of Puerto Rico; he had been in distress for roughly 24 hours and was dehydrated but in good health, and will be transferred from the tanker later.

North Atlantic Ocean Currents Show Signs of Critical Instability, Threatening Climate Stability

Scientists studying ancient clam shells have found evidence suggesting the Atlantic Ocean is nearing a critical tipping point in its current systems, which could lead to significant climate disruptions globally. The study highlights two destabilization episodes in the past 150 years, with current signs indicating increased instability, emphasizing the importance of reducing greenhouse gas emissions to prevent severe climate impacts.
