Magnetic disturbances caused by phenomena like the northern lights can be tracked by a 'social network' of ground-based instruments, according to a new study.
Researchers bring diurnal and seasonal variations into the lab to test the performance of perovskite solar cells under realistic conditions.
Beekeepers across the United States lost 40.7 percent of their honey bee colonies from April 2018 to April 2019, according to preliminary results of the latest annual nationwide survey conducted by the University of Maryland-led nonprofit Bee Informed Partnership. The survey results indicate winter losses of 37.7 percent, which is the highest winter loss reported since the survey began 13 years ago and 8.9 percentage points higher than the survey average.
Evidence from an Arctic ecosystem experiencing rapid climate change reveals surprisingly tight coupling of environmental responses to climate shifts. Links between abrupt climate change and environmental response have long been considered delayed or dampened by internal ecosystem dynamics, or only strong when climate shifts are large in magnitude. The research team presents evidence that climate shifts of even moderate magnitude can rapidly force strong, pervasive environmental changes across a high-latitude system.
Researchers found that the yields from grains such as millet, sorghum, and maize are more resilient to extreme weather in India; their yields vary significantly less due to year-to-year changes in climate and generally experience smaller declines during droughts. But yields from rice, India's main crop, experience larger declines during extreme weather conditions.
A protective layer of epoxy resin helps prevent the leakage of pollutants from perovskite solar cells (PSCs), report scientists. Adding a 'self-healing' polymer to the top of a PSC can radically reduce how much lead it discharges into the environment. This gives a strong boost to prospects for commercializing the technology.
A new study clarifies what influence major currents in the North Atlantic have on sea level along the northeastern United States.
Warming waters in the western tropical Pacific Ocean have significantly increased thunderstorms and rainfall, which may affect the stability of the West Antarctic Ice Sheet and global sea-level rise, according to a new tudy.
Giant petrels will be 'temporary' winners from the effects of climate change in the Antarctic region -- but males and females will benefit in very different ways, a new study shows.
The prime predators of the Baltic Sea at the top of the food web are losing weight, according to a new study that links the deteriorating health of gray seals and cod with changes in bottom-living crustaceans, isopods and amphipods.
Why did a giant hole appear in the sea ice off Antarctica in 2016 and 2017, after decades of more typical sea ice cover? Years of Southern Ocean data have explained the phenomenon, helping oceanographers to better predict these features and study their role in global ocean cycles.
An international survey finds that the number of honey bee colonies fell by 16 percent in the winter of 2017-18 across 38 countries.
A new study finds that how our community or neighborhood fares in an extreme storm or flood may have a stronger, more lasting effect on climate beliefs than individual losses do.
Atmospheric researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have now developed a climate model that can accurately depict the frequently observed winding course of the jet stream, a major air current over the Northern Hemisphere.
Researchers have developed a set of diode-based lidar instruments that could help fill important gaps in meteorological observations and fuel a leap in understanding, modeling and predicting weather and climate.
An aggressive new strain of sudden oak death, a disease that's killed millions of trees, has turned up in Oregon, posing a threat to timber production. Scientists are using a 3D model called Tangible Landscape to help stakeholders work together to find ways to contain the disease's spread.
In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that a quarter of its glacier ice is now affected, according to a new study.
An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the eruption triggered an unusually cold winter, according to a new study. The study will help improve predictions of how the climate will respond to future high-latitude volcanic eruptions.
Coral experts around the world said it was impossible to extract a multi-century record of El Niño events. But now a persistent effort has produced the world's first 400-year long record of El Niño events. And the changes researchers have found to El Niños in recent decades are startling.
Climate change has raised the risk of a fungal disease that ravages banana crops, new research shows.
