A new study projects that in coming decades the effects of high humidity in many areas may surpass humans’ ability to work or, in some cases, even survive.
The International Research Institute for Climate and Society’s Alessandra Giannini was selected as one of French President’s Macron’s climate laureates.

Last week, just days before Central Park’s big Ivory Crush, a Lamont-Doherty geochemist and his colleague sawed off samples of the confiscated ivory for DNA testing and radiocarbon dating. Their results could determine where and when each elephant was killed—which could help catch the poachers responsible.
Climate change could turn one of Africa’s driest regions wet, according to a new study. Scientists have found evidence in computer simulations for a possible abrupt change in the Sahel, a region long characterized by aridity and political instability. In the study, just published in the journal Earth System Dynamics, the authors detected a self-amplifying… read more
Students in the MPA Environmental Science and Policy program consulted with the David Sheldrick Wildlife Trust to create a strategic communications plan, raising awareness of elephant and rhino conservation efforts.
For a term project, Wendy Hapgood, MSSM ’16, investigated the possible illegal sale of ivory at shops in Manhattan. She found evidence for the largest ivory bust in New York state history.
