Giovani Graziosi is a Lecturer in Ecology, Evolution and Environmental Biology An undergraduate course in the Sustainable Development Program recently received a Course Support grant from the Earth Institute to conduct a special fieldwork project to develop the Columbia University Green Geodatabase (CUGG). The grant provides support to acquire some of the equipment and a… read more
If you take a look at nearly any satellite image of clouds in the tropics, you’ll notice that the clouds tend to be organized into clusters. One specific type of cloud organization called “self-aggregation.” Self-aggregation is the tendency of tropical clouds to spontaneously clump together, solely due to interactions between the clouds and the surrounding environment.
Philanthropy has evolved dramatically in recent years, changing the way individuals, organizations and foundations support the causes that concern them most. One manifestation of this evolution includes an array of sophisticated methods of investing in social causes while expecting a return, known as impact investing.
While we spent much of our time examining corals and swamps, studying sea level and storms, we became fascinated by a simple question: How did the hills of Exuma form?
In 2005, colleagues working in conflict resolution and peace-building in Iraq, Saudi Arabia, Israel, Palestine and Syria approached Columbia University’s International Center for Cooperation and Conflict Resolution with a request for science-based resources on constructive engagement made available in Arabic.
Today, on July 15th, we celebrate the first annual World Youth Skills Day, which recognizes that young people need technical and vocational education to excel at both the local and global level.
Help for Indian Small Farmers in a Changing Climate
While a much-needed insurance reform is a welcome change in the Indian agricultural sector, enabling smallholders to be self-sufficient in the wake of climate change and India’s alarming problem of groundwater depletion would be an added plus.
While the ice sheets on West Antarctica and the Antarctic Peninsula are usually the ones to make the news in relation to climate change, recent studies have documented transformations that are taking place on the East Antarctic Ice Sheet as well. On the continent as a whole, large areas of ice have already melted and this trend shows no sign of slowing, meaning the implications for global sea level rise in this century could be more dramatic than earlier projections anticipated.
Because we know little about hurricane behavior during periods when Earth was warmer or colder than at present, it’s challenging to construct models to predict future trends in hurricane activity as Earth’s climate changes. To remedy this problem, researchers have been working to reconstruct records of hurricane strikes in the past.
