    As human ancestors rose on two feet in Africa and began their migrations across the world, the climate around them got warmer, and colder, wetter and drier. The plants and animals they competed with and relied upon for food changed. Did the shifting climate play a direct role in human evolution?

    Dennis Kent, a leading expert in the history of earth’s magnetic field, has been elected to the American Academy of Arts and Sciences. Other members of the 2012 class include U.S. Secretary of State Hillary Rodham Clinton, playwright Neil Simon, Hollywood director Clint Eastwood and Amazon founder Jeffrey Bezos.

    Columbia University President Lee C. Bollinger and Provost John Coatsworth have named Sean C. Solomon, a leading geophysicist whose research has combined studies of the deep earth with missions to the moon and the solar system’s inner planets, to be director of Columbia’s Lamont-Doherty Earth Observatory.

    According to a new study, neighborhood differences in rates of childhood asthma may be explained by local levels of soot produced by trucks and residential oil burners. The study, by public-health and air-pollution scientists at Columbia University, appears

    online in the Journal of Exposure Science and Environmental Epidemiology.

    The seas are creeping higher as the planet warms, but scientists have not yet reached a consensus about how high they may go. Projections for the year 2100 range from inches to several feet, or more. The sub-tropical islands of Bermuda and the Bahamas contain important sites where researchers have gone looking for answers. By pinpointing where shorelines stood on cliffs and reefs there during an extremely warm period 400,000 years ago, they hope to narrow the range of global sea-level projections for the future.

    The world’s oceans may be turning acidic faster today from human carbon emissions than they did during four major extinctions in the last 300 million years, when natural pulses of carbon sent global temperatures soaring, says a new study in Science. The study is the first of its kind to survey the geologic record for evidence of ocean acidification over this vast time period.

    What does the earth look like beneath Mount St. Helens? Did a meteorite clear the ecological landscape for the dinosaurs? How did climate help Genghis Khan and his successors create the world’s largest empire? Just how high did the water rise the last time the ice sheets melted?
     
    In the field this year, scientists from Lamont-Doherty Earth Observatory and other centers of the Earth Institute will try to answer these and many other puzzles. They’ll ski-plane onto sea ice, climb mountains, hike through jungle, bore into rock and dive into the sea, exploring on every continent and in every ocean.

    Climate scientists at a meeting of the American Association for the Advancement of Science this week were elated to hear that the United States and five other countries had agreed to work toward cutting pollutants other than carbon dioxide thought to cause about a third of current human-influenced global warming. After all, many of them had done the work that led directly to the pact, by showing the effects of such substances, and how emissions might be reduced.

    Russian scientists this week finished penetrating more than two miles through the Antarctic ice sheet to Lake Vostok, a huge freshwater lake that has been buried under the ice for millions of years. The feat has taken two decades to accomplish, but the scientists won’t know what they’ve found until next year — the team quickly exited the research station, located in the middle of the continent 800 miles from the South Pole, to avoid increasingly harsh polar conditions.

    In California’s Death Valley, death is looking just a bit closer. Geologists have determined that the half-mile-wide Ubehebe Crater, formed by a prehistoric volcanic explosion, was created far more recently than previously thought—and that conditions for a sequel may exist today.

    Meteorologists can see a busy hurricane season brewing months ahead, but until now there has been no such crystal ball for tornadoes, which are much smaller and more volatile. This information gap took on new urgency after tornadoes in 2011 killed more than 550 people, more than in the previous 10 years combined, including a devastating outbreak in April that racked up $5 billion in insured losses..

    Earthquakes that have shaken an area just outside Youngstown, Ohio in the last nine months—including a substantial one on New Year’s Eve—are likely linked to a disposal well for injecting wastewater used in the hydraulic fracturing process, say seismologists at Columbia University’s Lamont-Doherty Earth Observatory who were called in to study the quakes.

    In many ways, the tiny, landlocked eastern Himalayan kingdom of Bhutan sits apart from the modern world; its rugged landscapes cradle swift-flowing rivers, expansive old-growth forests and hundreds of glaciers. Combining selective modernization with ancient traditions, it is the only country that uses Gross National Happiness as a metric for success. But the world is intruding. Rapid climate change is melting glaciers across the Himalayas, creating deadly flash-flood hazards and threatening a water system that feeds agriculture and hydropower here and for more than a billion people in the plains below.

    Scientists at Columbia University’s Earth Institute will present important new studies at the Dec. 5-9 meeting of the American Geophysical Union in San Francisco, the world’s largest gathering of earth and space scientists. Below: a chronological guide (Pacific Standard Time).

    In the first statewide climate change outlook for New York, scientists say that the state may suffer disproportionate effects in coming decades compared with other regions, due to its geography and geology. The report paints a harsh picture, including possible extreme temperature and sea-level rises, downpours, droughts and floods. The changes are projected to affect nearly every region and facet of the economy by the 2080s, from ski resorts and dairy farms to New York City’s subways, streets and businesses.
