Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. But it not directly measurable from space, due to the abundance of ozone higher in the atmosphere, which masks the surface. Now, researchers have devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to predict when and where ozone will form.
A thousand years ago, powerful Viking chieftans flourished in Norway’s Lofoten Islands, above the Arctic Circle. In an environment frequently hovering on the edge of survivability, small shifts in climate or sea level could mean life or death. People had to constantly adapt, making their living from the land and the sea as best they could.
The rise of the Vikings was not a sudden event, but part of a long continuum of human development in the harsh conditions of northern Scandinavia. How did the Vikings make a living over the long term, and what might have influenced their brief florescence? Today, their experiences may provide a kind of object lesson on how changing climate can affect civilizations.

It is the black before dawn at the gate to the Kanha Tiger Reserve, in the highlands of central India. The still air carries a dank, penetrating chill. But it is hardly quiet. A buzzing line of tourists is forming at the ticket booth, peddlers are pouring steaming cups of tea. Groups of green-uniformed rangers chat… read more
A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study.
A young researcher explains why she is taking to advocacy for science.
While federal support for new technology and infrastructure would be helpful, there is another approach that can also be effective. We should focus on modernizing our state and local energy systems. By modernizing the energy system we can reduce the costs and environmental impact of our energy use.
How do multiple stakeholders compromise their competing needs and develop a global coordinated strategy that is politically palatable, possible and comprehensive enough to have an impact? Students from universities all over the U.S. Northeast gathered at Columbia for the 2017 NASPAA-Batten Student Simulation Competition that challenged students to do just this.
