Phys.org / Acidifying oceans will cause a diversity and survival crisis for microscopic marine organisms, finds research
Oceanic responses to climate and human interactions have been studied for decades. In recent years the effects of increasing ocean acidity have been featured, with stark images of coral reefs being decimated by bleaching.
Phys.org / The rise and fall of the Roman empire preserved in pollen
Sediments at the bottom of the ocean can offer a window into the past, indicating environmental conditions not just from the sea but washed in from terrestrial runoff, as well as preserving the flora and fauna of the time. ...
Phys.org / Wind is a major driver of Antarctic deep water formation and the planet's ocean circulation, shows study
Earth's oceans are a complex system, and their interconnected nature has global implications. Around Antarctica, cold and dense waters form in the depths of the Southern Ocean. This is known as Antarctic Bottom Water (AABW). ...
Phys.org / 56 million-year-old Eocene global warming may indicate a wetter future
Modeling of Earth's response to global warming has suggested dry regions will become more arid and wet regions will experience more precipitation, with an uneven distribution of moisture in the atmosphere. With enhanced seasonality, ...
Phys.org / Remote lake emissions from the Tibetan Plateau challenge global climate modeling
Earth's complex systems interact between atmospheric, terrestrial, hydrological, cryological (ice and snow) and biological processes in feedback loops. Understanding their relationships is important for modeling their future ...
Phys.org / Coastal erosion could be reduced by dune restoration projects
Although sand dunes often conjure images of great deserts, they also occur along coastlines worldwide and can be an important buffer for communities threatened by sea level rise, storms and coastal erosion.
Phys.org / Climate modeling suggests monsoon origination up to 40 million years ago
Monsoons are seasonal climate conditions resulting from changes in wind that bring extreme drought or rain, depending upon the time of year. Those occurring in south Asia and east Asia are affected by a combination of atmospheric ...
Phys.org / China's Yanliao Biota offers a new window into mammal evolution since the Triassic
China's Yanliao Biota, an assembly of fossils preserved in northeastern China dating from the Middle to Late Jurassic (174 to 145 million years ago), offers an important window into the evolution of vertebrates. With exceptional ...
Phys.org / Seismic monitoring lasers may be the future for protecting global communications cables
The depths of the oceans are home to a complex ecosystem of marine organisms, but also a vast network of cables spanning the globe that aid communications. Earthquakes and tsunamis can potentially damage these important cables. ...
Phys.org / Trees as old as time: Using tree resin to reconstruct million-year old ecosystems
Fossil tree resins open a window into the deep past as their organic compounds, termed biomarkers, can be used to identify the botanical provenance of these ancient trees, as well as the paleoenvironmental conditions in which ...
