Climate can grind mountains faster than they can be rebuilt

This item was filled under Climate
For the first time, researchers have attempted to measure all the material leaving and entering a mountain range over more than a million years, and discovered that erosion caused by glaciation during ice ages can, in the right circumstances, wear down mountains faster than plate tectonics can build them....

Great Barrier Reef protecting against landslides, tsunamis

This item was filled under Climate
The world-famous Australian reef is providing an effective barrier against landslide-induced tsunamis, new research shows. An underwater landslide has been found to have occurred some 20,000 years ago, causing a tsunami. Similar submarine landslides could occur without our knowledge but the Great Barrier Reef can absorb some of that potential wave energy....

How Earth’s Pacific plates collapsed

This item was filled under Climate
Scientists drilling into the ocean floor have, for the first time, found out what happens when one tectonic plate first gets pushed under another. The international expedition drilled into the Pacific ocean floor and found distinctive rocks formed when the Pacific tectonic plate changed direction and began to plunge under the Philippine Sea Plate about 50 million years ago....

Climate study finds evidence of global shift in the 1980s

This item was filled under Climate
Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fueled by anthropogenic warming and a volcanic eruption, according to new research. Scientists say that a major step change, or 'regime shift,' in Earth's biophysical systems, from the upper atmosphere to the depths of the ocean and from the Arctic to Antarctica, was centered around 1987, and was sparked by the El Chichón volcanic eruption in Mexico five years earlier....
