Bleaching, It’s Not Just for Corals – Hakai Magazine
Giant clams suffer similar struggles with warming water, though the consequences don’t seem quite as dire.
Bleaching occurs when a stressed marine creature, most commonly a coral, expels its symbiotic algae and turns a ghostly white, often in response to a warming sea. But bleaching affects more than just corals. Giant clams—massive mollusks that can grow more than 1.2 meters in diameter and weigh as much as 225 kilograms—can bleach, too. And in recent research, scientists have learned more about how bleaching disrupts these sessile giants, affecting everything from their nutrition to their reproduction…
Long Story Shorts: What is a Coastal Geohazard? – Hakai Institute
Life can be pretty hazardous if you live on the coast—on top of wild weather events like hurricanes and tropical storms, you might find yourself in the middle of geological hazards like earthquakes, tsunamis, and landslides. But did you know that one geohazard can domino into another, creating a cascade of chaos?…
Cities Are Rapidly Reclaiming Land at Risk of Extreme Sea Level Rise – Hakai
As the sea rises and the population booms, builders around the world are in a race to transform coastal bays and shallow seas into new land. Yet don’t mistake this rush of land reclamation as a response to the challenges we face. “It’s built for rich people,” explains Dhritiraj Sengupta, a physical geographer at England’s University of Southampton. Sengupta’s latest research shows there’s been a huge increase in the use of reclaimed land for luxury hotels, shopping areas, and high-end living spaces—developments designed to boost a city’s global reputation…

Cruise Ship Invasion Interactive Feature – Hakai
Elizabeth Burton, a Seattle-based activist with the organization Seattle Cruise Control, calculated that the total climate impact of a typical Alaska cruising season, beginning and ending in Seattle (including flights), is equivalent to one-third of the city’s entire annual carbon emissions…After a one-year pandemic pause and a limited season in 2021, cruises to Alaska resumed and surged in popularity in 2022…an estimated 700,000 passengers will depart Seattle, Washington, on hundreds of different cruises. These travelers voyage on increasingly massive ships—some about three sport fields in length—that can house, feed, and process the waste of upward of 4,000 human beings…
How Will Creatures That Can Barely Move Handle Climate Change? – Hakai Magazine
As the world warms, animals living near the coast are being battered by stronger storms, rising seas, and extreme temperatures. While fish, birds, and other species might be able to escape—often toward the poles—many marine creatures can barely move, let alone speed out of the way.
Scientists have long known that on hot days more mobile shoreline creatures like crabs take steps to control their body temperature by scuttling into cool crevices…
Long Story Shorts: What is Symbiosis? – Hakai Magazine
You might think symbiosis is when two different species live in perfect harmony— but that’s just one kind of interaction. See what happens when symbiosis takes a dark turn…
Paleotsunami Detectives Hunt for Ancient Disasters – Hakai Magazine
Gigantic tsunamis have been decimating coastlines since time immemorial. We ignore these prehistoric warnings at our own peril.
A boulder weighing more than 40 tonnes sits on the sand high above the ocean. Dwarfing every other rock in view, it is conspicuously out of place. The answer to how this massive outlier got here lies not in the vast expanse of the Atacama Desert behind it but in the Pacific Ocean below…
