Day-to-day weather variations are growing more erratic and more extreme for at least one-third of the global climate.

Princeton's Michael Bender explains how tiny bubbles trapped for centuries in Antarctic ice, can reveal the history of the Earth's climate. Read the article in Climate Central.

Iain Couzin, assistant professor in the Department of Ecology and Evolutionary Biology at Princeton University, studies collective animal behavior.

Comparing wages across countries can be challenging. To address this, Orley Ashenfelter came up with the Big Mac Index, a measure of the number of minutes it takes for a McDonald's worker to earn enough money to buy a Big Mac sandwich.
