Smoke from wildfires ages in the atmosphere
Emissions, like smoke from wildfires and exhaust from vehicles, go through chemical changes when they enter the atmosphere. New research from the University of Georgia shows, for the first time, that these changes may affect what kind of treatment pa.....»»
Smoke from megafires puts orchard trees at risk: Effects last months, reducing nut yields
Long-term smoke exposure from massive wildfires lowers the energy reserves of orchard trees and can cut their nut production by half, researchers at the University of California, Davis, found. The smoke can affect trees for months after a megafire, d.....»»
Brazilians choke as fire smoke blankets 80% of country
With as much as 80 percent of Brazil under a blanket of smoke from historic wild fires, face masks last used during the coronavirus pandemic are coming out again......»»
Increased sea surface cooling from hurricanes observed along the Southeast Coast of the United States in recent decades
Utilizing satellite observations and ocean reanalysis datasets, researchers have analyzed the change in sea surface cooling induced by hurricanes and the corresponding ocean-atmosphere environment along the Gulf and Southeast coastal regions of the U.....»»
New mission to create total solar eclipses in space
A UK team of researchers including UCL's Professor Lucie Green are working on the launch of a spacecraft mission that will allow us to view the sun's atmosphere in more detail than ever before......»»
Why South America is burning
A record wave of wildfires, fueled by severe drought linked to climate change and deforestation, is causing havoc across South America......»»
Another building block of life can handle Venus" sulfuric acid
Venus is often described as a hellscape. The surface temperature breaches the melting point of lead, and though its atmosphere is dominated by carbon dioxide, it contains enough sulfuric acid to satisfy the comparison with Hades......»»
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.....»»
Quito fires coming under control after choking capital
Firefighters in Ecuador's capital were battling the remnants of major forest fires on Thursday that had sent massive plumes of smoke above Quito earlier this week, amid a record drought......»»
Ecuador capital "under attack" from five wildfires
Firefighters battled five blazes on the outskirts of Ecuador's capital Quito on Wednesday, as wildfires continue to rip through South American nations turned into tinderboxes by droughts linked to climate change......»»
Study shows Mars" early thick atmosphere could be locked up in the planet"s clay surface
Mars wasn't always the cold desert we see today. There's increasing evidence that water once flowed on the red planet's surface, billions of years ago. And if there was water, there must also have been a thick atmosphere to keep that water from freez.....»»
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.....»»
Amazon forest loses area the size of Germany and France, fueling fires
The Amazon rainforest has lost an area about the size of Germany and France combined to deforestation in four decades, fueling drought and record wildfires across South America, experts said Monday......»»
Astronomers catch a glimpse of a uniquely inflated and asymmetric exoplanet
An international group of researchers including University of Arizona astronomers, using NASA's James Webb Space Telescope, has observed the atmosphere of a hot and uniquely inflated exoplanet. The exoplanet, which is the size of Jupiter but only a t.....»»
Potential indicators of life on other planets can be created in a lab
One way to understand the potential for life on far-off planets—those in other solar systems that orbit different stars—is to study a planet's atmosphere. Telescopic images often capture traces of gases that may indicate life and habitable planet.....»»
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.....»»
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.....»»
Algorithm used on Mars rover helps scientists on Earth see data in a new way
A new algorithm tested on NASA's Perseverance Rover on Mars may lead to better forecasting of hurricanes, wildfires, and other extreme weather events that impact millions globally......»»
Life might thrive on the surface of Earth for an extra billion years
The sun is midway through its life of fusion. It's about 5 billion years old, and though its life is far from over, it will undergo some pronounced changes as it ages. Over the next billion years, the sun will continue to brighten......»»
Location, location, location: Snowpack storage and runoff timing in burn scars depend on site and terrain
Increasingly severe wildfires at high elevations are impacting snowpack—an important reservoir for the U.S. West. The altered landscape makes it more challenging to predict when snow will melt and how much water will be available for use......»»
Sea surface micro layer: Researchers study boundary between the ocean and the air
The boundary between the ocean and the atmosphere, where the air and sea interact, is known as the sea surface microlayer. Understanding how nutrients, pollutants and organic matter are exchanged between the air and the sea is also vital for better u.....»»
