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.....»»
Why Earthlings are safe when huge solar storms strike our planet
When solar storms and coronal mass ejections hit Earth and create the Northern Lights, people are physically protected from radiation by Earth's magnetic field and atmosphere. From time to time, the sun discharges billions of tons of solar matt.....»»
Canadian oil city lifts wildfire evacuation orders
Residents forced to flee wildfires threatening a Canadian oil-producing hub were allowed to return home Saturday after evacuation orders were lifted......»»
Hawaii study shows almost 75% of Maui wildfire survey participants have respiratory issues
A University of Hawaii study examining the health effects of last year's deadly wildfires on Maui found that up to 74% of participants may have difficulty breathing and otherwise have poor respiratory health, and almost half showed signs of compromis.....»»
Canadian oil sands city evacuated as wildfire draws near
Thousands of residents of Fort McMurray, a city in Canada's major oil-producing region, fled as an out-of-control wildfire drew near and thick smoke filled the skies......»»
Health systems eliminating a form of anesthesia that hangs in the air for more than a decade after use
Philadelphia-area health systems are phasing out a common anesthesia gas that hangs in the atmosphere for 14 years. Desflurane is the most potent greenhouse gas found in hospitals, which are increasingly engaged in efforts to reduce their carbon foot.....»»
A novel flame-retardant, smoke-suppressing and superhydrophobic transparent bamboo for future glasses
Professors Yiqiang Wu and Caichao Wan, along with their team from Central South University of Forestry and Technology (CSUFT), have pioneered a transparent material derived from natural bamboo. This material features a three-layered flame-retardant b.....»»
NASA’s Quest to Touch the Sun
The outer layers of the sun’s atmosphere are a blistering million degrees hotter than its surface. NASA sent a probe to find out why—by getting closer to the star than ever before......»»
No sign of widespread lead exposure from Maui wildfires, Hawaii health officials say
Lead screening conducted on west Maui residents after last summer's devastating wildfires showed no widespread exposure to the toxic metal, Hawaii health officials said Thursday......»»
Study finds consistent decline in nitrogen oxides emissions from human activities in China since 2020
Nitrogen oxides (NOx) form aerosols and ozone in the atmosphere and are significant contributors to air pollution and climate change. China is the largest emitter, yet accurate and timely information on NOx emissions in China has been lacking since 2.....»»
Unearthing the impacts of hydrological sensitivity on global rainfall
Georgia Tech researcher Jie He set out to predict how rainfall will change as Earth's atmosphere continues to heat up. In the process, he made some unexpected discoveries that might explain how greenhouse gas emissions will impact tropical oceans, af.....»»
James Webb telescope peers at the atmosphere of a rocky hell world
Webb recently investigated the exoplanet 55 Cancri e, finding what could be the first atmosphere of a rocky planet discovered outside the solar system......»»
Webb presents best evidence to date for rocky exoplanet atmosphere
Researchers using NASA/ESA/CSA James Webb Space Telescope may have detected an atmosphere surrounding 55 Cancri e, a rocky exoplanet 41 light-years from Earth. This is the best evidence to date for a rocky planet atmosphere outside our solar system......»»
High hopes for carbon capture, underground storage
Capturing carbon dioxide (CO2) from the atmosphere to store underground "sounds too good to be true", a climate expert told AFP, yet the technology to increase its capacity tenfold is already being tested......»»
Nanoparticle catalysts convert carbon dioxide to carbon monoxide to make useful compounds
As a greenhouse gas, carbon dioxide (CO2) contributes to climate change as it accumulates in the atmosphere. One way to reduce the amount of unwanted CO2 in the atmosphere is to convert the gas into a useful carbon product that can be used to generat.....»»
Radio astronomers bypass disturbing Earth"s atmosphere with new calibration technique
An international team of researchers led by astronomers from Leiden University (Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Eart.....»»
Extreme heat drives Chile wildfires leaving at least 51 dead
Chileans Sunday feared a rise in the death toll from wildfires blazing across the South American country that have already killed at least 51 people, leaving bodies in the street and homes gutted......»»
Researcher: Climate models can run for months on supercomputers—but my new algorithm can make them ten times faster
Climate models are some of the most complex pieces of software ever written, able to simulate a vast number of different parts of the overall system, such as the atmosphere or ocean. Many have been developed by hundreds of scientists over decades and.....»»
Are carbon-capture models effective?
Reforestation efforts to restock depleted forests are important for addressing climate change and for both capturing and restoring carbon from the Earth's atmosphere. These types of solutions to mitigate carbon emissions are critical after 2023 prove.....»»
Contemporary wildfires not more severe than historically in western US dry forests: Study
Wildfires have increased over the last few decades in dry forests, which cover 25.5 million ha (63 million acres) of the western U.S. But are high-severity fires that kill 70% or more of trees already burning at rates that exceed historical (preindus.....»»
Research quantifies "gap" in carbon removal for first time—shows countries need more awareness, ambition and action
New research involving the University of East Anglia (UEA) suggests that countries' current plans to remove CO2 from the atmosphere will not be enough to comply with the 1.5ºC warming limit set out under the Paris Agreement......»»
