Geologist reveals correlation between earthquakes, landslides in Peru

Tue, 11/04/2014 - 11:13
A geologist has demonstrated that earthquakes -- not climate change, as previously thought -- affect the rate of landslides in Peru. "Geologic records of landslide activity offer rare glimpses into landscapes evolving under the influence of tectonics and climate," says a researcher whose expertise includes geomorphology and tectonics. "Because deposits from individual landslides are unlikely to be preserved, it's difficult to reconstruct landslide activity in the geologic past. Therefore, we've developed a method that measures landslide activity before and after the last glacial-interglacial climate transition in Peru."

Arctic warming: Scientists identify new driver

Mon, 11/03/2014 - 15:19
A mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice has been identified by scientists. They found that open oceans are much less efficient than sea ice when it comes to emitting in the far-infrared region of the spectrum, a previously unknown phenomenon that is likely contributing to the warming of the polar climate.

Variations in ice sheet height influence global climate

Mon, 11/03/2014 - 15:19
Heinrich events, in which large masses of icebergs rapidly broke free from ice sheets during the last ice age, are thought to have influenced global climate by interrupting ocean circulation patterns with a large influx of freshwater. However, new research suggests the variations in the height of the ice sheet that happen in these events might also influence global climate.
