As Arctic summers warm, Earth’s northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air and soil temperatures lead to increased plant growth.
A research team has developed a new theory that can predict the movement of an animal’s sensory organs — such as eyes, ears and nose — while searching for something vital to its life.
The 2020 minimum extent, which was likely reached on Sept. 15, 2020 measured 1.44 million square miles (3.74 million square kilometers).
Sea ice is frozen ocean water that melts each summer, then refreezes each winter. “The year 2020 will stand as an exclamation point on the downward trend in Arctic sea ice extent.” Shrinking sea ice is just one of many…
During wildfires, nitrous acid plays a leading role — spiking to levels significantly higher than scientists expected, driving increased ozone pollution and harming air quality, according to a new study.
Researchers report the first ever clear images of nanojets — bright thin lights that travel perpendicular to the magnetic structures in the solar atmosphere, called the corona — in a process that reveals the existence of one of the potential coronal heating candidates: nanoflares.
(Fundação de Amparo à Pesquisa do Estado de São Paulo) Analysis published in Scientific Reports is based on climate models for the mid-Pliocene period, which occurred 3 million years ago and shared characteristics with present-day warming.
For more than 20 years, Metronome, which includes a 62-foot-wide 15-digit electronic clock that faces Union Square in Manhattan, has been one of the city’s most prominent and baffling public art projects. Its digital display once told the time in…
