    Tackling carbon emissions in China

    A Beijing symposium co-sponsored by the Harvard China Project and the Harvard Global Institute explored the possibility of China adopting a carbon tax as a way to reduce climate-warming greenhouse gas emissions. The Gazette spoke with economist Dale Jorgenson, the Samuel W. Morris University Professor, and Chris Nielsen, the executive director of the China Project,…

    Quantum computing, no cooling required

    Using a pair of impurities in ultra-pure, laboratory-grown diamonds, researchers have created room-temperature quantum bits and have stored information in them for nearly two seconds — an increase of nearly six orders of magnitude over the life span of earlier systems. The work, described in the June 8 issue of Science, is a critical first…

    Illuminating carbon’s climate effects

    Harvard researchers compiled ice and sedimentary core samples collected from dozens of locations around the world, and found evidence that while changes in Earth’s orbit may have touched off a warming trend, increases in CO2 played a far more important role in pushing the planet out of the ice age.

    Rock sleuths

    In one of the largest studies of its kind, Harvard researchers have found that carbon records from the mid-Neoproterozoic era can be “read” as a faithful snapshot of the surface carbon cycle between 717 million and 635 million years ago, a finding that directly challenges a decades-long belief of most scientists.

    Ambitious undertaking

    U.S. Undersecretary of Energy Kristina Johnson said the United States plans to have 80 percent of its energy come from alternative and unconventional fossil fuels by 2050. She spoke as part of the “Future of Energy” discussion series sponsored by the Harvard University Center for the Environment.
