From sediment cores to speleothems, environmental archives are helping us to understand the history of wildfires.
GPS Observations Sense Groundwater Change in Australia
By exploiting the fact that changes in groundwater cause deformations of the Earth’s surface, GPS receivers are used to detect groundwater changes related to extreme events and to seasonal oscillations.
Wildfire Smoke Destroys Ozone
Smoke aerosols from large wildfires are the perfect reaction surface for chlorine chemicals, speeding their transformation from ozone-friendly forms to reactive ones.
Making Sense of the Great Barrier Reef’s Mysterious Green Donuts
Researchers set sail to the Great Barrier Reef to study how ring-shaped algae deposits formed and evolved, what feeds them, and the diversity of creatures that call them home.
Last Tree Standing
Refugia repopulate forests after fires, but climate change is making these woodlands increasingly unpredictable.
A Day in the Life Used to Be 17 Hours
The Moon was a lot closer to Earth 2.46 billion years ago, and the shorter distance contributed to shorter days.
A Mysterious Dome Reveals Clues to Australia’s Miocene History
The Nullarbor Plain has been relatively untouched by geological forces, leaving traces of the continent’s deep past.
Surprise Hydrological Shifts Imperil Water Resources
Mounting evidence suggests the need for improved water planning strategies and revamped hydrological models.
A Spike in Wildfires Contributed to the End-Permian Extinction
An upward trend in fossilized charcoal indicates that wildfires may have contributed to extinctions during the Great Dying.
Tree Mortality Risk Surges in Australian Rain Forests
Researchers link vulnerability to “atmospheric drought” associated with climate change.
