A study shows that the lower incidence of disease in the Ethiopian highlands at the turn of the century has a close connection with a temporary slowdown in global warming
NASA's Perseverance Rover recently made a successful landing on Mars, embarking on a two-year mission to seek signs of ancient life and collect samples. Because Mars is extremely cold -- nighttime temperatures can drop below -112 F -- heaters are required to keep the rover's battery system from freezing. Now, researchers reporting in ACS' Nano Letters have 3D printed porous carbon aerogels for electrodes in ultralow-temperature supercapacitors, reducing heating needs for future space and polar missions.
From ice skating, it has been known for a long time that a thin liquid film forms on ice surfaces. This, along with other causes, is responsible for ice slipperiness. Scientists at the Max Planck Institute for Polymer Research have now investigated a related effect at interfaces between ice and porous clay minerals. Such interfaces are found in nature for example in permafrost. The results may help to better understand changes in frozen soils as temperatures rise.
Results from Malaysian Borneo demonstrate that small, fragmented patches of regenerating logged forests left on hilltops will be slow to recover due to lower water availability, even more in the future as hotter and drier weather will be more common than now as a result of climate change.
For the first time, two researchers--one from the University of Copenhagen and the other from Columbia University--have accurately dated the arrival of the first herbivorous dinosaurs in East Greenland. Their results demonstrate that it took the dinosaurs 15 million years to migrate from the southern hemisphere, as a consequence of being slowed down by extreme climatic conditions. Their long walk was only possible because as CO2 levels dropped suddenly, the Earth's climate became less extreme.
A global observation of an ongoing atmospheric drying -- known by scientists as a rise in vapor pressure deficit -- has been observed worldwide since the early 2000s. In recent years, this concerning phenomenon has been on the rise, and is predicted to amplify even more in the coming decades as climate change intensifies.
More Antarctic meltwater is surfacing than was previously known, modifying the climate, preventing sea ice from forming and boosting marine productivity- according to new research from the University of East Anglia (UEA). For the first time, researchers have been able to obtain full-depth glacial meltwater observations in winter, using instruments attached to the heads of seals living near the Pine Island Glacier, in the remote Amundsen Sea in the west of Antarctica.
Nuisance flooding has increased on U.S. coasts in recent decades due to sea level rise, and new research co-authored by the University of Central Florida uncovered an additional reason for its added frequency -- higher local tide ranges. The results are in a study appearing today in the journal Science Advances.
Western butterfly populations are declining at an estimated rate of 1.6% per year, according to a new report to be published this week in Science. The report looks at more than 450 butterfly species, including the western monarch, whose latest population count revealed a 99.9% decline since the 1980s.
Volcanic eruptions, not natural variability, were the cause of an apparent "Atlantic Multidecadal Oscillation," a purported cycle of warming thought to have occurred on a timescale of 40 to 60 years during the pre-industrial era, according to a team of climate scientists who looked at a large array of climate modeling experiments.
