BRUNY ISLAND, TASMANIA (WASHINGTON POST) - Even before the ocean caught fever and reached temperatures no one had ever seen, Australia's ancient giant kelp was cooked.. Read more at straitstimes.com.
Alaska’s Arctic landscape is under assault from a warming climate, and it’s happening a lot faster than anticipated.
Hunters say grizzly bears are showing up in growing numbers on islands of the Beaufort Sea.
Temperatures across the Arctic have been warmer than usual this fall, with one community in the Northwest Territories recording above-average temperatures for 72 days in a row.
Open water has become the November norm in the Chukchi Sea northwest of Alaska. Instead of thick, years-old ice, researchers are studying waves and how they may pummel the northern Alaska coastline.
NOAA Fisheries' summer trawl survey shows Norton Sound red king crab are moving, Arctic cod numbers have dropped significantly, and Pacific cod are continuing to increase as the Northern Bering Sea ecosystem undergoes drastic change.
The fast-warming Sea of Okhotsk, wedged between Russia and Japan, is a cautionary tale of the far-reaching consequences when climate dominoes begin to fall.
For half a century, Taku had been the one known Alaskan glacier to withstand the effects of climate change – until now.
Regulations have lowered mercury emissions globally, but the risks to ocean ecosystems and human health may be getting worse.
As we rolled into November, scientists discovered last month was the warmest October on record globally.
The islands were first noticed by a student engineer who had observed the unidentified land masses in satellite images
Around the world, rising temperatures pose a threat to the species.
Toxic algal blooms which can be fatal to humans, are increasing across the world as temperatures rise, according to the first global survey of dozens of freshwater lakes based on 30 years of NASA data.
Waters off the coast of Maine are warming faster than 99 percent of the world's oceans. That's forcing whales northward in pursuit of prey, threatening some of their already dwindling populations.
Under extreme heat stress, corals expel their symbiotic algae and colour (that is, ‘bleaching’), which often leads to widespread mortality. Predicting the large-scale environmental conditions that reinforce or mitigate coral bleaching remains unresolved and limits strategic conservation actions1,2. Here we assessed coral bleaching at 226 sites and 26 environmental variables that represent different mechanisms of stress responses from East Africa to Fiji through a coordinated effort to evaluate the coral response to the 2014–2016 El Niño/Southern Oscillation thermal anomaly. We applied common time-series methods to study the temporal patterning of acute thermal stress and evaluated the effectiveness of conventional and new sea surface temperature metrics and mechanisms in predicting bleaching severity. The best models indicated the importance of peak hot temperatures, the duration of cool temperatures and temperature bimodality, which explained ~50% of the variance, compared to the common degree-heating week temperature index that explained only 9%. Our findings suggest that the threshold concept as a mechanism to explain bleaching alone was not as powerful as the multidimensional interactions of stresses, which include the duration and temporal patterning of hot and cold temperature extremes relative to average local conditions.
It already has caused coral bleaching in Hawaii and may be tied to strandings of marine mammals along the California coast.
Short-tailed shearwaters breed in the areas off Australia. They come to Alaska to gorge on krill, tiny copepods, fish and a variety of other marine food. Shearwaters that were not dead were found to be extremely weakened, some of them trying to eat scraps from Bering Sea fishermen’s nets.
Following Hurricane Dorian, large parts of the Bahamas have been left in a state of ruin, made unlivable to the hundreds of thousands of people who have called the islands their home.
South winds and warm water are hitting sea ice on Arctic waters with a double whammy.
