The noise of shipping vessels traveling through northern Canadian waters is causing Arctic cod to sacrifice much of their foraging and feeding in order to flee the area until ships move away, researchers report.
Global warming and extinction risk
How can fossils predict the consequences of climate change? A German research team from FAU, the Museum of Natural History Berlin and the Alfred Wegener Institute compared data from fossil and marine organisms living today to predict which groups of animals are most at risk from climate change.
Antarctica hits warmest temperature ever recorded
The temperature in northern Antarctica hit nearly 65 degrees (18.3 degrees Celsius), a likely heat record on the continent best known for snow, ice and penguins.
Permafrost collapse is speeding climate change, study warns
Abrupt thawing of permafrost will double previous estimates of potential carbon emissions from permafrost thaw in the Arctic, and is already rapidly changing the landscape and ecology of the circumpolar north, a new CU Boulder-led study finds.
Scientists find record warm water in Antarctica, pointing to cause behind troubling glacier melt
A team of scientists has observed, for the first time, the presence of warm water at a vital point underneath a glacier in Antarctica—an alarming discovery that points to the cause behind the gradual melting of this ice shelf while also raising concerns about sea-level rise around the globe.
The world’s wetlands are a haven for wildlife, but we need to learn to love them
They’re widely perceived as a waste of land, better used for something more productive. As a result, vast areas of the world’s wetlands are being converted to other uses.”They’re the forgotten realm. Wetlands are really valuable … but are suffering the biggest losses of biodiversity of all.” Read more
The Pacific Ocean is now so acidic that it’s dissolving crabs’ shells
Ocean acidification along the Pacific Northwest coast is partially dissolving the shells of Dungeness crabs and damaging the valuable crustaceans’ sensory organs, according to a new study. Read more
Oceans are warming at the same rate as if five Hiroshima bombs were dropped in every second
The world’s oceans are now heating at the same rate as if five Hiroshima atomic bombs were dropped into the water every second, scientists have said. Read more
Humanity’s emissions ‘100-times greater’ than volcanoes
Human activity churns out up to 100 times more planet-warming carbon each year as all the volcanoes on Earth, says a decade-long study released Tuesday.
Oil spills reach more than 100 regions of Brazil’s coast
Brazil’s main environmental agency said Thursday it has detected 105 crude oil spills from an undetermined source polluting the waters of the country’s northeast coast this month.
Fish can feel pain like mammals, scientist says
Fish experience pain on a level comparable to mammals, according to a scientist who has debunked the common misconception that the animals aren’t capable of such sensation.
Microplastics may affect how Arctic sea ice forms and melts
If people assume the Arctic environment is unaffected by what humans discard into the oceans, they are wrong. The pristine waters of the Arctic Ocean are under silent threat by those particles as they drift along with the ocean currents over long distances.
