    Science and Heritage: The Ice Memory Foundation’s Mission for the Planet

    As climate change threatens an uncertain future, an international foundation is collecting and saving stories from the past in an unusual format: ice cores from disappearing glaciers that act as archives for both data and memories.

  • Glacial Ice Cores Reveal 15,000 Year Old Microbes

    Glacial Ice Cores Reveal 15,000 Year Old Microbes

    Ancient ice contains a rich microbial record going back thousands of years. Recent advances have provided tools to study their genes and evolution, but climate change threatens to erase this frozen archive.

  • Perfume Fragrances Found in Glacial Ice on Russia’s Mount Elbrus

    Perfume Fragrances Found in Glacial Ice on Russia’s Mount Elbrus

    An ice core records the dramatic increase in the use of perfumes and other personal care products between the 1930s and 2005.

  • Glaciers May Record the Story of the Coronavirus Pandemic

    Glaciers May Record the Story of the Coronavirus Pandemic

    Reductions in human emissions and changes in atmospheric composition during the coronavirus pandemic might be observed in future glacial ice cores.

    Accounting for Volcanoes Using Tools of Economics

    Climate scientists teamed up with an econometrics expert to develop an innovative new method for picking out past volcanic eruptions in temperature reconstructions going back millennia and gauging their impact on the climate.

    Crossing 400ppm: Welcome to the Pliocene

    “Right now, we’re living in a world of a Pliocene atmosphere,” scientist Maureen Raymo of the Lamont-Doherty Earth Observatory tells the Yale Forum on Climate Change and the Media. “But the whole rest of the climate system — the oceans are trying to catch-up, the ice sheets are waning, and everything is trying to catch…

  • Two Climate Scientists Win 2012 Vetlesen Prize for Work on Ozone Hole, Ice Cores

    An American atmospheric chemist who led efforts to identify the cause of the Antarctic ozone hole and a French geochemist who extracted the longest-yet climate record from polar ice cores have won the prestigious 2012 Vetlesen Prize. Susan Solomon and Jean Jouzel will share the $250,000 award, considered to be the earth sciences’ equivalent of…

  • Volcanoes Cool the Tropics, Say Researchers

    But Global Warming May Have Helped Override Some Recent Eruptions

  • Cosmic Dust in Ice Cores Sheds Light on Earth’s Past Climate

    Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years, a finding that could help refine efforts to understand the timing and effects of changes…
