A new NASA study confirms that the surface temperature of Greenland’s massive ice sheet has been rising, stoked by warming air temperatures, and fueling loss of the island’s ice at the surface and throughout the mass beneath. Greenland’s enormous ice sheet is home to enough ice to raise sea level by about 23 feet if […]
Imagine a gigantic, inflatable, sausage-like bag capable of storing 160 million tons of carbon dioxide — the equivalent of 2.2 days of current global emissions. Now try to picture that container, measuring up to 100 meters in radius and several kilometers long, resting benignly on the seabed more than 3 kilometers below the ocean’s surface. […]
It has been 40 million years since the waters around Antarctica have been warm enough to sustain populations of sharks and most fish, but they may return this century due to the effects of global warming. If they do, the impact on Antarctic ecology could be serious. Biologists analyzed the physiological adaptations and metabolism of […]
The Earth’s orbital behaviors are responsible for more than just presenting us with a leap year every four years. According to one professor of earth and planetary sciences, parameters such as planetary gravitational attractions, the Earth’s elliptical orbit around the sun and the degree of tilt of our planet’s axis with respect to its path […]
The small Pacific Island nation of Kiribati has become a global conservation leader by establishing the world’s largest marine protected area — a California-sized ocean wilderness of pristine coral reefs and rich fish populations threatened by over-fishing and climate change.
