    After the recent great quakes that have swept away entire coastlines and cities in Japan, Haiti and Sumatra, scientists are now looking hard at the nation that may suffer the gravest threat of all: Bangladesh. A new documentary from the Earth Institute follows seismologists as they trace signs of deeply buried active faults, past movements of the earth, and sudden, catastrophic river-course changes.

    A team led by Kevin Anchukaitis of the Lamont-Doherty Earth Observatory Tree Ring Lab is currently in Alaska’s Arctic National Wildlife Refuge, studying the effects of changing climate on trees. Ferried in by a bush pilot who landed on the tundra to drop them off, they are practically at treeline–the place where it is too far north for trees to grow. But there are still some spindly white spruces here, and they are taking cores from these, which can be used to measure weather of the past.

    This spring, Columbia University Professor and Lamont-Doherty researcher Nicholas Christie-Blick, along with graduate teaching assistant Elizabeth Pierce, led 19 first- and second-year undergraduates on an eight-day expedition to investigate the dynamic processes that formed Death Valley’s exquisite natural beauty.

    Stronger ocean currents beneath West Antarctica’s Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A growing cavity beneath the ice shelf has allowed more warm water to melt the ice, the researchers say—a process that feeds back into the ongoing rise in global sea levels. The glacier is currently sliding into the sea at a clip of four kilometers (2.5 miles) a year, while its ice shelf is melting at about 80 cubic kilometers a year - 50 percent faster than it was in the early 1990s - the paper estimates.

    Starting today, armchair explorers will be able to view parts of the deep ocean floors in far greater detail than ever before, thanks to a new synthesis of seafloor topography released through Google Earth. Developed by oceanographers at Columbia University’s Lamont-Doherty Earth Observatory from scientific data collected on research cruises, the new feature tightens resolution in covered areas from the former 1-kilometer grids to just 100 meters.

    During the last ice age, the Rhone Glacier was the dominant glacier in the Alps, covering a significant part of Switzerland. Over the next 11,500 years or so, the glacier, which forms the headwaters of the Rhone River, has been shrinking and growing again in response to shifts in climate.

  • May 26, 2011

    El Niño and La Niña, the periodic shifts in Pacific Ocean temperatures, affect weather around the globe, and many scientists have speculated that a warming planet will make those fluctuations more volatile, bringing more intense drought or extreme rainfall to various regions.

    The hole in the Earth’s ozone layer over the South Pole has affected atmospheric circulation in the Southern Hemisphere all the way to the equator, and a new study says this has led to increased rainfall in the subtropics. The study, which appears in the April 21 issue of the leading journal Science, is the first time that ozone depletion has been linked to climate change over such a wide area.

    As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned. But oddly, despite bitter cold winters in the north, Antarctica was heating up. For the two decades since ice core records revealed that Europe was cooling at the same time Antarctica was warming over this thousand-year period, scientists have looked for an explanation.

    Wallace Broecker is a climate scientist at Lamont-Doherty Earth Observatory who has helped shape our understanding of how the ocean moves heat around the globe, and how this so-called “great ocean conveyor” can switch the climate to a radically different state. Many scientists used to think that only periodic changes in earth’s orbit—so-called Milankovitch cycles– could change climate, over thousands of years, but Broecker has shown that ocean currents can influence climate in mere decades–and could do so again. He spoke with journalist Kim Martineau about his latest book, “The Great Ocean Conveyor: Discovering the Trigger for Abrupt Climate Change.”

    The earthquake that struck Haiti took place along what is called a strike-slip fault—a place where tectonic plates on each side of a fault line are moving horizontally in opposite directions, like hands rubbing together. When these plates lock together, stress builds; eventually they slip; and this produces shaking.
