    Confessions from a Former Coniferphile

    The first time I felt truly fanatical about coniferous trees was while walking among the great eastern white pine trees in the Adirondack State Park as an undergraduate research assistant and student.

    Unsettled by Climate Change

    Climate change already laps at the edges of some communities, disrupting local economies and habitat, and forcing resettlement. But a new study notes that any efforts to offset the effects of shifting climate could lead to even more displacement and disruption for many people, particularly the poor.

  • Migration in the Face of Global Environmental Change

    Migration in the Face of Global Environmental Change

    Over the past 40 years, coastal and inland water ecosystems experienced the greatest levels of net in-migration, vs. mountain, forest, cultivated, and dryland ecosystems, which experienced the greatest levels of net out-migration, says a new report.

    Water Problems Are Solvable: The International Water Forum at the UN

    Water problems are solvable. None of the many challenges are outside of the ability of human-kind to respond and resolve. As with so many things, political will and money are needed, but the International Water Forum at the UN took it further; the general public has to understand and care before the political will and…

    Wondrous Wildlife of The Week – The Pebble Toad

    Organisms in the natural world are constantly striving to avoid predation. Some prey depend on morphological characters to outsmart a worthy predator, utilizing camouflage or mimicry to avoid detection; others must engage in battle, relying on agility or strength. The Venezuela pebble toad, however, has an extremely peculiar defense mechanism: it rolls itself into the…

  • Rising Seas Pushing Island Nations to the Brink

    Rising sea levels caused by global warming could displace millions of people worldwide who are living on low-lying coastlines, and it may prove fatal to some small island nations. At a conference at Columbia Law School, legal experts explored the implications for the people whose homelands could become uninhabitable within a matter of decades.

    How to reduce weather risk (and make a little green)

    People understand that weather can affect certain markets — especially energy prices and other commodities — but its impact on portfolios more broadly might surprise. Just last week, a new study was released that estimated $485 billion of annual weather-related economic impact in the United States alone. Another calculated the effect at nearly 10 times that amount…

    Insuring the World’s Poorest Farmers

    Index insurance could help small-scale farmers build wealth and cope with climate change, but more accurate weather and climate data is needed for index insurance to catch on, writes Daniel Osgood, a scientist at Columbia University’s International Research Institute for Climate and Society (IRI). In a new piece in Nature Geoscience, Osgood and colleagues outline…
