Invasion Without the Body Snatchers

A study led by Dartmouth researchers shows that microscopic marine animals called zooplankton (pictured) can be enticed to ingest organic carbon particulates in seawater that are later confined to the deep ocean in the animals' feces. The researchers found that clay sprayed on the water's surface bonds with the carbon, creating sticky balls that become part of the ravenous little creatures' daily smorgasbord.

Leveraging the food of tiny phytoplankton could trap carbon and sequester it to the ocean’s bottom.

Windblown embers can trigger spot fires much further away than expected. Now a new mathematical model of the way the wind interacts with firebrands explains why.

Only a tiny percentage of the globe experienced cooler than normal temperatures during January through October. As the red and pink colors in this map of the globe show, almost all of Earth's surface was unusually warm — and a significant portion, including North America, South America, Europe, Africa, and Oceania, was record warm.

Feverish Earth

This year likely will end as warmest on record, and new findings show Earth's icy places are suffering. Meanwhile, CO2 emissions continue rising — and efforts to turn the climatic tide are increasingly threatened.

The Arctic at Night

Even as winter takes hold in the Arctic, sea ice there is growing sluggishly. In Antarctica, summer’s arrival has driven sea ice to near-record lows.
