Climate May Quickly Drive Forest-Eating Beetles North, Says Study

Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle, one of the world’s most aggressive tree-killing insects, through much of the northern United States and southern Canada, says a new study.

Despite a strict ban on ivory trafficking in NY, these pieces were found for sale in 2016.

Fighting Ivory Trafficking with Forensic Science

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.
