Arctic warming and diminishing sea ice are influencing the atmosphere
The researchers of the Institute for Atmospheric and Earth system research at the University of Helsinki have investigated how atmospheric particles are formed in the Arctic. Until recent studies, the molecular processes of particle formation in the.....»»
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.....»»
Arctic sea ice near historic low; Antarctic ice continues decline
Arctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on Sept.11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC). The decline.....»»
"Invisible forest" of phytoplankton thrives as ocean warms, study shows
An "invisible forest" of phytoplankton is thriving in part of our warming ocean, new research shows......»»
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......»»
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.....»»
Data from robots show steady increase in deep-ocean warming
New research published Sept. 19 in Geophysical Research Letters shows that using data collected by deep ocean robots, called Deep Argo floats, combined with historical data from research vessels has increased confidence that parts of the global deep.....»»
Study reveals large ocean heat storage efficiency during the last deglaciation
As one of the largest heat reservoirs in the climate system, the global ocean absorbs more than 90% of the excess energy from ongoing anthropogenic warming. In the last century, the greatest warming in the ocean has occurred in the upper 500 m, with.....»»
The Multiple Ways Climate Change Threatens to Make Migraines Worse
Migraine sufferers are often triggered by the weather, and research suggests warming temperatures and more extreme weather events worsen attacks......»»
Arctic weather satellite"s first images capture Storm Boris
Just a month after its launch, ESA's Arctic Weather Satellite has already delivered its first images, notably capturing Storm Boris, which has been wreaking havoc across central Europe......»»
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.....»»
Arctic warming may fuel ice formation in clouds, observations suggest
The Arctic frequently experiences temperatures that support the formation of mixed-phase clouds that contain supercooled liquid droplets and ice crystals. The composition of such clouds plays a crucial role in the region's energy balance and climate.....»»
Antioxidant carbon dot nanozymes alleviate depression in rats by restoring the gut microbiome
Depression is a significant challenge to diagnose and treat. Among the factors influencing depression onset and severity, there is growing evidence for chemical imbalances that generate oxidative stress throughout the body. To address this problem, r.....»»
The Arctic Seed Vault Shows the Flawed Logic of Climate Adaptation
The difficulties of the Svalbard seed repository illustrate why we need to prevent climate disaster rather than plan for it.....»»
Project 2025 Would Drastically Cut Support for Carbon Removal
The Heritage Foundation’s plan for a potential Trump second term has little time for schemes to suck carbon dioxide out of the atmosphere......»»
Polaris Dawn crew member describes the dramatic ride home
A member of SpaceX’s Polaris Dawn mission has described what it was like aboard the Crew Dragon as it entered Earth’s atmosphere at high speed last weekend......»»
Low-noise amplifiers aboard the Arctic Weather Satellite
The Arctic Weather Satellite (AWS) of the European Space Agency (ESA) was sent on its journey to a polar orbit 600 km above the Earth on August 16, 2024. On board: four low-noise amplifiers (LNAs) from the Fraunhofer Institute for Applied Solid State.....»»
Environment takes center stage as global summits loom
