We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the way that climate change can cause fluctuations in CO2 levels? New research from an international team of scientists reveals one of the mechanisms by which a colder climate was accompanied by depleted atmospheric CO2 during past ice ages. The overall goal of the work is to better understand how and why the earth goes through periodic climate change, which could shed light on how man-made factors could affect the global climate. Earth's average temperature has naturally fluctuated by...

Cities. They sprawl and tangle, juxtaposing ancient public squares and glistening skyscrapers. They provide homes for half of humanity, and economic and cultural centers for the rest. It has taken us thousands of years to build today's urban centers, and yet, they're expected to double in land-area in just the next few decades. "Half the urban infrastructure we will be using in 2050 has not yet been built," said Elie Bou-Zeid, an associate professor of civil and environmental engineering at Princeton.  Though this growth is inevitable, the way these cities will...

In spring 2017, PEI is launching Global Perspectives on Environmental Justice. This event series will feature writers, filmmakers, other visual artists, and scholars whose work engages fundamental questions of environmental justice. Our visitors will address the political, imaginative and ethical challenges that result from unequal exposure to environmental risk and unequal access to environmental resources. Global Perspectives on Environmental Justice is coordinated by: Anne McClintock, A. Barton Hepburn Professor of Gender and Sexuality Studies, and Rob Nixon, Currie C. and Thomas A...

Jane Baldwin, a Ph.D. candidate in Atmospheric and Oceanic Sciences at Princeton University, has received a top student paper award from the American Meteorological Society’s (AMS) Board on Environment and Health. Her winning presentation at AMS’ Eighth Conference on Environment and Health was titled “Quantifying the Risk of Compound Heat Wave Events.” It analyzed heat-wave events and their probabilities in the present and projected future. Baldwin is a fellow with Princeton Environmental Institute’s Program in Science, Technology, and Environmental Policy...

Gabe Vecchi is a world-famous atmospheric scientist with a pretty simple attitude to making progress: In order to do something, you need to do it. And Gabe’s done a lot! He was born in Boston but grew up in Venezuela, and witnessed the country’s dissolution from an intellectual magnet for South America into a dystopian nightmare. Going into the interview, I wondered about Gabe’s perspective on the anti-science, inward-looking trends we’re now seeing in the US. Are we headed for the same fate? At this point, it’s impossible to say. But what I can say is that Gabe’s enthusiasm...

For decades, among the most enduring questions for ecologists have been: "Why do species live where they do? And what are the factors that keep them there?" A Princeton University-based study featured on the February cover of the journal Ecology could prove significant in answering that question, particularly for animals in the world's temperate mountain areas. The researchers spent two years documenting the distribution of 70 bird species across the Himalayas in India and found that temperature and habitat predominantly determine the elevations where the birds live. Earlier...

At a vegetable farm in West Africa, where the planting is done by hand, questions about weather boil down to the most urgent question of all:  Will the rains be good or bad? Princeton professor Eric Wood, a hydrologist who usually works with global data and computer models, visited the small farm an hour out of Niamey, Niger, in 2013. There, he spoke with the very people who would benefit from a new drought and flood risk monitoring system that he had created. Farmers in Niamey rely on their agricultural agents, and by extension Wood's program, to tell them when the rains will...
