"Scientists found that even before the layers of snow atop sea ice begin to melt away, the snow warms and its optical conditions change, allowing fractionally more light to filter down to the underside of the sea ice -- enough to trigger algal growth."

"Starting in 2014, teams at Protix researched different types of insects. Eventually, they discovered that the black soldier fly has a large amount of protein stored during its larvae stage because the fly doesn’t eat once it is hatched. Salmon, which are notoriously picky, liked the food made from the black soldier flies better than the other alternatives."

"Permafrost, the Arctic’s frozen soil, acts as a massive ice trap that keeps carbon stuck in the ground and out of the atmosphere — where, if released as carbon dioxide, the greenhouse gas would drive global warming. But as humans warm the climate, they risk thawing that permafrost and releasing that carbon, with microbial organisms becoming more active and breaking down the ancient plant life that had previously been preserved in the frozen earth. That would further worsen global warming, further thawing the Arctic — and so on."

"New emergency water restrictions went into effect last week for the city that once was considered to be at the forefront of Africa's green movement. Only a month ago, level six restrictions had placed residents on a daily allowance of 87 liters (about 23 gallons), illustrating the severity of the crisis."

"Bleaching doesn’t necessarily kill coral, though it does turn it an eerie bone white. A type of photosynthetic algae called zooanthellae lives in the tissues, producing nutrients and carbon that the coral uses for energy. The symbiotic algae also give corals their stunning colors. When coral undergoes stress from pollution, loss of light, or increasing water temperatures, the zooanthellae are ejected, causing the coral to lose its color and food supply. If things go back to normal relatively quickly, the algae can often recolonize the coral and the system survives."

"These creatures are filter feeders, meaning they consume large quantities of small prey by straining them out of the ocean water. In the process, they swallow hundreds to thousands of cubic metres of water daily, meaning there is the potential for them to take in substantial amounts of microplastic floating in the water."
