How much longer will the oxygen-rich atmosphere be sustained on Earth?
(Toho University ) Earth’s modern atmosphere contains copious amounts of molecular oxygen (O2), representing an important remotely detectable sign of life. However, a fundamental question of how much longer the Earth’s oxygen-rich atmosphere will persist into the far future remains uncertain. A new study finds that a highly-oxygenated atmosphere is not a permanent feature even for Earth, which has implications for the search for life beyond the solar system.
Hotter, drier, CRISPR: editing for climate change
(University of Queensland) Just 15 plant crops provide 90 per cent of the world’s food calories. A review of genome editing technologies published in Theoretical and Applied Genetics states gene editing technology could play a vital role to play in climate-proofing future crops to protect global food security. The review recommends integrating CRISPR-Cas9 genome editing into modern breeding programs for crop improvement in cereals.
Whatâs the coldest Earth has ever been?
Our planetâs history includes episodes of cold so extreme that glaciers reached sea level in equatorial regions.
Under climate stress, human innovation set stage for population surge
(Washington University in St. Louis) Aridification in the central plains of China during the early Bronze Age did not cause population collapse, a result that highlights the importance of social resilience to climate change, according to new research from Washington University in St. Louis. Instead of a collapse amid dry conditions, development of agriculture and increasingly complex human social structures set the stage for a dramatic increase in human population around 3,900 to 3,500 years ago.
Pioneering prehistoric landscape reconstruction reveals early dinosaurs lived on tropical islands
(University of Bristol) A new study using leading edge technology has shed surprising light on the ancient habitat where some of the first dinosaurs roamed in the UK around 200 million years ago.
Gulf Stream System at its weakest in over a millennium
(Potsdam Institute for Climate Impact Research (PIK)) Never before in over 1000 years the Atlantic Meridional Overturning Circulation (AMOC), also known as Gulf Stream System, has been as weak as in the last decades. This is the result of a new study by scientists from Ireland, Britain and Germany. The researchers compiled proxy data, reaching back hundreds of years to reconstruct the AMOC flow history. They found consistent evidence that its slowdown in the 20th century is unprecedented in the past millennium.
New model describes wave behavior in straits, predicts killer waves
(Skolkovo Institute of Science and Technology (Skoltech)) A Skoltech researcher has developed a theoretical model of wave formation in straits and channels that accounts for nonlinear effects in the presence of a coastline. This research can improve wave prediction, making maritime travel safer and protecting coastline infrastructure.
