Baleen whales have changed their distribution in the Western North Atlantic

Researchers using passive acoustic recordings of whale calls to track their movements have found that four of the six baleen whale species found in the western North Atlantic Ocean — humpback, sei, fin and blue whales — have changed their distribution patterns in the past decade. The recordings were made over 10 years by devices moored to the seafloor at nearly 300 locations from the Caribbean Sea to western Greenland.

When calling loudly, echolocation is costly for small bats

Calling in the ultrasonic range enables small bats to orient themselves in the dark and track down insects. Louder calls travel farther, improving a bat’s ability to detect their prey. It was long assumed that echolocation does not contribute much to energy expenditure in flight because individuals couple their calls with the beat of their wings. Scientists have now shown that high intensity echolocation calls substantially contribute to energy expenditure.

Scientists urge caution, further assessment of ecological impacts above deep sea mining

A new study argues that deep-sea mining poses significant risks, not only to the area immediately surrounding mining operations but also to the water hundreds to thousands of feet above the seafloor, threatening vast midwater ecosystems. Further, the scientists suggest how these risks could be evaluated more comprehensively to enable society and managers to decide if and how deep-sea mining should proceed.

Even if we start to fix climate change, the proof may not show up for 30 years – The Washington Post

In short, because of the massive amount of fossil fuels burned since the Industrial Revolution, and the complexity of the Earth’s climate, there’s no quick payoff from changing our fossil fuel habits, researchers found. The results lend added perspective to…

Covid-19 and climate change: Why we need to remember what we’ve lost – Vox.com

For as long as I’ve followed global warming, advocates and activists have shared a certain faith: When the impacts get really bad, people will act. Maybe it will be an especially destructive hurricane, heat wave, or flood. Maybe it will…
