The gross ecosystem product, or GEP, tries to take into account the contribution of nature to the economy.
Narwhals, recognizable by their large single tusk, make distinct sounds that are now being analyzed in depth by researchers.
An expert on climate denial offers tips for inoculating people against coronavirus conspiracy notions.
Exoplanet hunters are moving beyond simply finding new planets into trying to know what they look like and whether there's surface or subsurface activity.
Scientists are exploring the use of fiber-optic cables—like the ones that form the backbone of the internet—to monitor earthquakes. Julia Rosen reports.
Following dietary guidelines would mean eating less meat and dairy—and fewer calories overall—reducing greenhouse gases and other pollution. Julia Rosen reports.
Exhaust fumes from oceangoing vessels lead to an almost doubling of lightning activity over shipping lanes compared to adjacent areas of the sea.
A trove of scientific notes from the early 1900s suggests a warming climate is driving birds to migrate earlier to New York’s Mohonk Preserve. Julia Rosen reports.
Century-old records found in Puerto Rico helped reconstruct the damage caused there by a magnitude 7.3 earthquake—and could help disaster experts plan for the next big one. Julia Rosen reports. ...
Really big meteorite or asteroid strikes may cause melting and deep deformations that eventually lead to volcanic eruptions.
Starting in the next century, atmospheric carbon levels could begin to approach those of hundreds of millions of years ago, and have their warming effect augmented by a brighter sun. ...
The storm that swept across the Rockies in September 2013 unleashed huge amounts of sediment downstream, doing the work of a century of erosion. Julia Rosen reports.
Researchers used ancient climate cycles to confirm the solar system’s chaotic planetary orbits. An Earth–Mars collision is one distant outcome. Julia Rosen reports.
Critters living more than six miles below the ocean surface contain high levels of harmful compounds like PCBs and flame retardants. Julia Rosen reports.
Researchers look into the future of the far North for clues to save species and maybe even bring back sea ice
Arctic heat waves melt sea ice, which promotes more warming and even more ice loss. In other words, it’s a snowball effect—or in this case, an anti-snowball effect. Julia Rosen reports...
Researchers think Mars may have experienced a series of climate cycles, which etched the planet’s surface with river valleys and lake basins. Julia Rosen reports.
When the sun, moon and Earth are aligned, high tidal stress may increase the chances that an earthquake will grow bigger than it otherwise might have been.
Great frigate birds may stay aloft for up to two months, eating and sleeping on the wing.
Rockfalls without an obvious cause (like an earthquake or expanding ice) may be due to hot daily air temperatures expanding small cracks in cliff faces.
