Algal Bloom Turns Sea Lions Behind Surge in Aggressive Attacks on California Coast

Algal Bloom Turns Sea Lions Behind Surge in Aggressive Attacks on California Coast

Breaking News, Climate Actions
A mysterious and disturbing shift is unfolding along California’s scenic coastline, where usually playful sea lions are turning violent lunging at beachgoers, biting surfers, and displaying what experts are calling "demonic" behaviour. The cause? A toxic algal bloom that’s wreaking havoc on marine ecosystems and warping the minds of sea lions. Weighing up to 300 kilograms, adult male sea lions are powerful marine mammals. Their sudden shift from friendly companions to unpredictable attackers has alarmed wildlife authorities, marine biologists, and locals alike. Though no fatalities have occurred, dozens of people have been bitten in recent weeks, and the danger continues to grow. But the aggression isn’t rooted in natural hostility. It’s heartbreakingly unnatural driven by a neurotox...

Threatening Millions Addis Ababa Climate Change Fuels Global Water Crisis Global Threat

Breaking News, Climate Actions, Environment
In Addis Ababa, Ethiopia, a young girl waits in a long line for water, clutching an empty container. The queue stretches down the dusty road as families gather under the scorching sun hoping to fill their buckets before supplies run out. This scene has become increasingly common in cities and rural areas around the world, where climate change is disrupting water systems and leaving millions without access to safe drinking water. From East Africa to North America, extreme weather events wildfires, floods, droughts, and heatwaves are pushing water infrastructure to its limits. Rivers are drying up, reservoirs are shrinking, and contamination is on the rise. Scientists and policymakers warn that without immediate action, the situation will only get worse, putting lives at risk and deepenin...
Climate Change Threatens Thames with Increased Algal Blooms Despite Phosphorus Reduction 80%

Climate Change Threatens Thames with Increased Algal Blooms Despite Phosphorus Reduction 80%

Breaking News, Climate Actions, Disasters, Environment
A new study has warned that climate change could fuel a rise in algal blooms in the River Thames, even though phosphorus levels an essential nutrient for algae have significantly decreased over the past four decades. Led by Helen Jarvie, a professor at the University of Waterloo, the research found that phosphorus loads in the Thames have dropped by 80% due to improved wastewater treatment and agricultural practices. Despite this progress, rising river temperatures driven by climate change are increasing the risk of both spring diatom blooms and summer cyanobacterial blooms. These algal blooms can harm aquatic ecosystems by suffocating marine life, depleting oxygen levels, and releasing potentially toxic cyanobacteria. Water Quality Management at Risk Jarvie emphasized that while ...

AI to Forecast Toxic “Blue-Green Tides”: A Breakthrough in Battling Harmful Algal Blooms

Breaking News, Climate Actions, Environment
A team of scientists at Los Alamos National Laboratory is leveraging artificial intelligence to forecast toxic algal blooms, known as harmful algal blooms (HABs), which have become increasingly common due to climate change and rising water temperatures. These blooms, which have now been reported in all 50 U.S. states, pose a significant threat to water bodies by closing beaches and lakes, killing aquatic life, and causing billions in economic damage. "Harmful algal blooms are appearing in areas where, historically, they were never present," said Babetta Marrone, the project's lead scientist. The complexity of the ecosystems causing these blooms, combined with dispersed data across various databases, presents a unique opportunity for AI to aid in understanding and predicting these events...
