Unraveling the mysteries of consecutive atmospheric river events
In California's 2022-2023 winter season, the state faced nine atmospheric rivers (ARs) that led to extreme flooding, landslides, and power outages—the longest duration of continuous AR conditions in the past 70 years. Scientists at Lawrence Berkele.....»»
New study reveals why the mighty Darling River is drying up—and it"s not just because we"re taking too much water
Water flows in mainland Australia's most important river system, the Murray-Darling Basin, have been declining for the past 50 years. The trend has largely been blamed on water extraction, but our new research shows another factor is also at play......»»
How climate change affects deer—experts draw findings from 20 years of research
Temperature, rainfall, snow and extreme weather events are all factors linked to climate change that directly affect wildlife. Understanding the impact of these factors on the physiology, population dynamics and distribution of different deer species.....»»
High-energy-density cubic gauche nitrogen successfully synthesized at atmospheric pressure
A research group led by Prof. Wang Xianlong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has successfully synthesized high-energy-density materials cubic gauche nitrogen (cg-N) at atmospheric pressure by treating.....»»
New approach reveals details about aerosol properties from hard-to-sample areas in the atmosphere
The spatial distribution of ambient aerosol particles plays a huge role in aerosol–radiation–cloud interactions; however, not enough sampling has been done from the atmospheric boundary layer and lower free troposphere. This leaves large gaps in.....»»
Enhancing hurricane forecasts: Simulations reveal reducing estimates of atmospheric friction improves storm predictions
Hurricanes and other extreme weather events are expensive in lives and money. From 1980 to 2023, weather and climate disasters caused about $2.6 trillion in damages in the U.S., according to NOAA estimates. In 2022 alone, the U.S. experienced 18 disa.....»»
Drought reduces Amazon River in Colombia by as much as 90%: report
The Amazon River has seen its levels in Colombia reduced by as much as 90 percent, a government agency said Thursday, as South America faces a severe and widespread drought......»»
Some people insist the Tijuana River is poisoning them: Officials disagree
The Tijuana River should not be flowing this time of year. But throughout the dry season, it has—delivering millions of gallons a day of an unnatural mix of water, neon green sewage and industrial waste from Tijuana through the city of Imperial Bea.....»»
Future climate change predicted to shift flood-generating mechanisms and intensify extreme flooding events
The Delaware River Basin, a coastal watershed in the Mid-Atlantic region, has a long history of severe flooding with significant socioeconomic impacts. Recent research uses a process-based modeling approach to analyze hydrometeorological (like rainfa.....»»
Satellite data fusion enhances the early detection of convective clouds
As global warming continues, convective weather events are becoming more frequent. The early stage of these storms, known as convective initiation (CI), can be monitored using geostationary satellites. However, detecting CI accurately remains a chall.....»»
Scientists uncover a critical component that helps killifish regenerate their fins
Spontaneous injuries like the loss of a limb or damage to the spinal cord are impossible for humans to repair. Yet, some animals have an extraordinary capacity to regenerate after injury, a response that requires a precise sequence of cellular events.....»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
Climatologists develop more accurate El Niño Southern Oscillation forecasts
Australian climatologists closely monitor atmospheric and oceanic conditions to assess the risk of El Niño Southern Oscillation (ENSO) events occurring, which can lead to devastating natural disasters, however these predictions have become somewhat.....»»
Evaluating the flow of information for high-impact weather events
Sixteen years to the day that Hurricane Katrina devastated Louisiana, Ida slammed into the Gulf Coast state's seaport town of Port Fourchon as a Category 4 cyclone on Aug. 29, 2021, leaving a widespread path of destruction......»»
Atmospheric methane increase during pandemic due primarily to wetland flooding, satellite data analysis finds
A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight decrease in atmospheric hydroxide (OH). The resul.....»»
Feeding coral reefs can aid their recovery from bleaching events
Coral reefs will continue to experience severe heat stress as rising temperatures cause the oceans to become unbearably hot—but a new study shows that altering their feeding habits could allow local populations to avoid total extinction......»»
In the gateway to the Arctic, fat, ice and polar bears are crucial. All three are in trouble.
Searching for polar bears where the Churchill River dumps into Canada's massive Hudson Bay, biologist Geoff York scans a region that's on a low fat, low ice diet because of climate change......»»
Arlo Secure gets powerful new AI features, including person and vehicle detection
Arlo Secure can now send you personalized alerts when people or vehicles enter your property. You can even create custom alerts for specific motion events......»»
Study raises questions about validity of standard model of solar flares
Solar flares are extremely intense events that occur in the sun's atmosphere, lasting anywhere from a few minutes to several hours. According to the standard flare model, the energy that triggers these explosions is transported by accelerated electro.....»»
Advanced civilizations will overheat their planets within 1,000 years, researchers suggest
Earth's average global temperatures have been steadily increasing since the Industrial Revolution. According to the National Oceanic and Atmospheric Agency (NOAA), Earth has been heating up at a rate of 0.06°C (0.11°F) per decade since 1850—or ab.....»»
High-resolution images of the sun show how flares impact the solar atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from ex.....»»
