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…

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.

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…
