Weevils, long-nosed beetles, are unsung heroes of pollination
Some of nature's most diverse pollinators often go unnoticed, even by scientists: long-snouted beetles called weevils. A new study provides a deep dive into...
Iron-rich rocks unlock new insights into Earth’s planetary history
A new study suggests iron-rich ancient sediments may have helped cause some of the largest volcanic events in the planet's history.
Deep sea surveys detect over five thousand new species in future mining hotspot
There is a massive, mineral-rich region in the Pacific Ocean -- about twice the size of India -- called the Clarion-Clipperton Zone (CCZ), which...
Most effective ways of foraging can attract predators
Animals using the most of efficient methods of searching for resources may well pay with their lives, scientists have discovered.
Recent reduced abyssal overturning and ventilation in the Australian Antarctic Basin
AbstractDense water formed near Antarctica, known as Antarctic bottom water (AABW), drives deep ocean circulation and supplies oxygen to the abyssal ocean. Observations show...
Very short-lived halogens amplify ozone depletion trends in the tropical lower stratosphere
AbstractIn contrast to the general stratospheric ozone recovery following international agreements, recent observations show an ongoing net ozone depletion in the tropical lower stratosphere...
Philosophers reinforce economists’ support for climate change mitigation
The value of climate change mitigation largely depends on the social discount rate, which has almost exclusively been influenced by economists. A survey of...
Slowing of the ocean’s deep breath
The deepest reaches of the ocean are ventilated by sinking of cold and relatively saline seawater around Antarctica. Observations from the Australian sector of...
Stratospheric ozone loss by very short-lived substances
The ozone layer is slowly recovering due to the Montreal Protocol. The only exception is the ozone in the tropical lower stratosphere, which keeps...
Philosophers and economists agree on climate policy paths but for different reasons
AbstractThe estimated value to society from climate change mitigation is highly sensitive to the long-term social discount rate. Governmental discounting guidance has almost exclusively...
