Species that live in symbiosis with others, which often occur in the most delicately balanced and threatened marine ecosystems such as coral reefs, are the slowest to recover their diversity if damag…
A long-standing debate in the field of cultural evolution has revolved around the question of how and why human societies become more hierarchical. Some theorize that material changes to a society…
In the summer of 2010-2011 Western Australia experienced an unprecedented marine heat wave that elevated water temperatures 2-4°C above average for more than 2 months. The heat wave resulted in defol…
Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked, according to new research on Australia's Great Barrier Ree…
A team led by scientists from Scripps Institution of Oceanography at the University of California San Diego and the J. Craig Venter Institute (JCVI) has demonstrated that the excess carbon dioxide ad…
The temperature and salinity of seawater are key drivers for the global ocean circulation system. Warm and saline water transported poleward cools at the surface when it reaches high latitudes and be…
A new NASA study has, for the first time, cut a clear path through a nettlesome problem: accurately measuring a powerful effect on global sea level that lingers from the last ice age. Glacial isostat…
A major study into an ancient climate change event that affected a significant percentage of Earth's oceans has brought into sharp focus a lesser-known villain in global warming: oxygen depletion…
A team led by geochemist Dr. Katharina Pahnke from Oldenburg has discovered important evidence that the rise in atmospheric carbon dioxide levels at the end of the last ice age was triggered by chang…
When simulating future environmental conditions researchers face a problem: laboratory experiments are easy to control and to reproduce, but are insufficient to mimic the complexity of natural ecosys…
Global sea level rise is not cruising along at a steady 3 mm per year, it's accelerating a little every year, like a driver merging onto a highway, according to a powerful new assessment led by C…
Hundreds of methane flares observed offshore Western Svalbard in the Arctic are caused by a process that started at the end of the last ice age, according to the study. The methane release happens be…
On a far flung peninsula halfway up the coast of Western Australia are strange piles of cubic boulders that look like rusty refrigerators and boxes. Decorating their flat faces are more than one mill…
The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study identifies the details of how ocean acidification affects coral skeletons, …
