A study published Wednesday shows nearly all the world’s glaciers have been melting at an accelerated pace in recent years, accounting for rises in sea level over the last two decades. In the study, published in the science journal Nature, an international group of scientists used high resolution imagery from NASA’s Terra satellite to study 220,000 […]
“Faster ice melting under global warming was the most likely cause of the directional change of the polar drift in the 1990s.” Since 1980, the planet’s north and south poles have moved roughly four meters in distance, and new research shows that shifts in the Earth’s rotational axis have accelerated since the 1990s as a […]
The U.S space agency NASA says its Perseverance rover has converted carbon dioxide (CO2) in the Martian atmosphere to oxygen, a critical step toward future human exploration of Mars. NASA on Monday said a toaster-size, experimental instrument on the rover called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE), produced about 5.4 grams of […]
