Methane emitted by humans vastly underestimated
by •
Researchers measured methane levels in ancient air samples and found that scientists have been vastly underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels. The …read more Source:: Science
Astronomers detect large amounts of oxygen in ancient star’s atmosphere
by •
Astronomers have detected large amounts of oxygen in the atmosphere of one of the oldest and most elementally depleted stars known. This new finding provides an important clue on how …read more Source:: Science
Microplastic drifting down with the snow
by •
Over the past several years, microplastic particles have repeatedly been detected in sea-water, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and …read more Source:: Science
Some corals can survive in acidified ocean conditions, but have lower density skeletons
by •
Coral reefs face many challenges to their survival, including the global acidification of seawater as a result of rising carbon dioxide levels in the atmosphere. A new study shows that …read more Source:: Science
Counter-intuitive climate change solution
by •
A seemingly counterintuitive approach — converting one greenhouse gas into another — holds promise for returning the atmosphere to pre-industrial concentrations of methane, a powerful driver of global warming. …read more Source:: Science
Scientists discover what powers celestial phenomenon STEVE
by •
The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like those that power the aurora, according …read more Source:: Science
Arctic warming will accelerate climate change and impact global economy
by •
Carbon released into the atmosphere by the increasing loss of Arctic permafrost, combined with higher solar absorption by the Earth’s surface due to the melting of sea ice and land …read more Source:: Science
A warming world increases air pollution
by •
The new study shows that the contrast in warming between the continents and sea, called the land-sea warming contrast, drives an increased concentration of aerosols in the atmosphere that cause …read more Source:: Science
Melting ice sheets release tons of methane into the atmosphere
by •
The Greenland Ice Sheet emits tons of methane according to a new study, showing that subglacial biological activity impacts the atmosphere far more than previously thought. …read more Source:: Science
