Many vertebrate species would have to evolve about 10,000 times faster than they have in the past to adapt to the rapid climate change expected in the next 100 years, a new study has found.

Wildfires produce a witch’s brew of carbon-containing particles, as anyone downwind of a forest fire can attest. But measurements taken during the 2011 Las Conchas fire near Los Alamos National Laboratory show that the actual carbon-containing particles emitted by fires are very different than those used in current computer models, providing the potential for inaccuracy in current climate-modeling results.

In a development that will help predict sea level rise, scientists have used an innovation in radar analysis to accurately image the vast subglacial water system under West Antarctica’s Thwaites Glacier, detecting a swamp-like canal system several times as large as Florida’s Everglades. The new observations suggest dynamics of the subglacial water system may be as important as ocean influences in predicting the fate of Thwaites, which holds substantial potential for triggering sea-level rise.

By studying rapidly evolving bacteria as they diversify and compete under varying environmental conditions, researchers have shown that temporal niches are important to maintaining biodiversity in natural systems.
