A single industry accounts for around 5 percent of global carbon dioxide (CO2) emissions. It produces a material so ubiquitous it is nearly invisible: cement. It is the primary ingredient in concrete, which in turn forms the foundations and structures of the buildings we live and work in, and the roads and bridges we drive…

The weather started to get increasingly worse yesterday, with a lot of clouds, low visibility and snow. That, of course, means that we couldn’t go out flying for two days. The forecast for the next 24 hours doesn’t look promising either. But as usual in the Arctic it’s better not to forecast — everything might…

Approximately one in eight children dies before the age of 5 in sub-Saharan Africa – a rate that has been declining, but is still nearly 20 times higher than in developed nations. A new Lancet study out this week suggests that the multiple interventions applied in the Millennium Villages Project are having a significant impact,…
Undergraduate students learn about summer field opportunities in Jordan, the Dominican Republic and Puerto Rico offered through the Summer Ecosystems Experience for Undergraduate (SEE-U) program at Columbia.
The 2012 field season started out better than we could hope for. The weather has been great for flying out onto the ice and sampling water from the Arctic ocean. We were able to get water samples from three stations, including one at the North Pole.

Earth Institute scientists explore how the physical world works on every continent — over and under the arctic ice, in the grasslands of Mongolia, on volcanoes in Patagonia, over subduction zones in Papua New Guinea, and on the streets of New York City.

The group traveled by boat, motorcycle and finally by foot through the forest to reach cliffs where burials lay. At one site, 20 feet off the forest floor was a ledge protected by an overhang, where lay a row hollowed-out logs, along with ceramic jars.

Amelia Paukert considers herself “environmentally inclined” because of her early exposure to nature and horseback riding in her native Napa Valley, California. Her fascination with the water cycle helped spark her passion for environmental science.

After another day spent hiding out in the Aleutian Islands, we are headed northeast towards the sea ice to attempt recovery of two oceanographic moorings. The weather is improved, only a couple of days remain for scientific study, and we are excited to hopefully accomplish one of the main goals of this cruise!
