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…
By Justin Nobel, Columbia University Earth and Environmental Sciences Journalism Student My first impressions of Africa came from reading National Geographic articles like those in 2000 and 2001 chronicling ecologist Michael Fay’s African “megatransect.” His 2,000-mile, 456-day trek across the rainforests of the Republic of the Congo, Cameroon and Gabon described an impenetrable wilderness unspoiled…
Researchers at the Center for Climate Systems Research (CCSR), a part of The Earth Institute, have developed a high-resolution map of projected population change for the year 2025. The innovative map shows a world with large areas of population loss in parts of Eastern Europe and Asia, but significant gains elsewhere. The work, Mapping the…
By Justin Nobel, Columbia University Earth and Environmental Sciences Journalism Student My time here is coming to an end and I still can’t determine if development will prove sustainable for Sauri’s bird population. The goal of the Millennium Villages Project (MVP) is to help Sauri, and several other villages in sub-Saharan Africa, develop economically. The…
The destruction caused by natural disasters such as Hurricane Katrina and human activities such as mountaintop removal mining are powerful examples of how the environment and society are tightly interwoven. But to what extent do, or should, state science curricula in the U.S. seek to investigate or influence the nature of this interaction? That is…
The Earth Institute at Columbia University and the University of Iceland signed an agreement on June 13, 2006 endorsing increased academic exchange, scholarly collaboration and research between the two institutions. The agreement sets the stage for future cooperation on global climate change, sustainable development and technological responses to climate change. The Memorandum of Understanding was…
Dwi Susanto is a senior staff associate and director of Indonesian research coordination at Lamont-Doherty who specializes in studying tropical ocean circulation. He was visiting Jakarta recently when an earthquake struck his home town on the island of Java. He contributed this report on conditions in Indonesia. Report from Indonesia On Saturday morning May 27,…
The end of the recurring, 100,000-year glacial cycles is one of the most prominent and readily identifiable features in records of the Earth’s recent climate history. Yet one of the most puzzling questions in climate science has been why different parts of the world, most notably Greenland, appear to have warmed at different times and…
By Justin Nobel, Columbia University Earth and Environmental Sciences Journalism Student Sending a postcard home from Sauri requires four cinnamon-chested bee-eaters and one African fish eagle. Birds are popular in Kenya and their images are ubiquitous. Different species are featured on ten- and five-shilling stamps, appear in cell-phone advertisements and grace tourism posters in Nairobi’s…
