Water Is Streaming Across Antarctica
In the first such continent-wide survey, scientists have found extensive drainages of meltwater flowing over parts of Antarctica’s ice during the brief summer. Many of the newly mapped drainages are not new, but the fact they exist at all is significant; they appear to proliferate with small upswings in temperature, so warming projected for this…

Webcast Today: Rich and Poor, and the Essence of El Niño
How does El Niño work, and how does it affect our climate, food supplies and water availability? The two men whose scientific work has been key to solving these puzzles will be honored Wednesday with the Vetlesen Prize, marking a major achievement in Earth sciences. And this afternoon, they’ll have something to say about it…

Our Economy Depends on Earth Observation and Scientific Research
If we are to continue to grow our economy without destroying the planet’s basic systems that sustain human life, we need to learn a great deal more about our planet and the impact of human activities on natural systems.

Pratigya Polissar Sees Landscapes Changing Through a Microscope
The word fossils typically conjures images of T-Rexes and trilobites. Pratigya Polissar thinks micro: A paleoclimatologist, he digs into old sediments and studies molecular fossils—the microscopic remains of plants and animals that can tell us a lot about what was living in a particular time period.

Park Williams Discovers History and Science in a Tree Ring
Park Williams studies trees and climate, in particular the causes of drought and the effects of climate change on forests. In this latest in a series of Earth Institute videos, we spoke to him about what he does, what’s important about it, and how his interest in history and environmental science blended into a career.

The Science of Carbon Dioxide and Climate
The vast majority of scientists around the world agree that our climate is changing at a faster rate than ever recorded in human history because of our use of fuels such as coal and oil, so-called fossil fuels. The conclusion rests on basic physics known since the early 1800s, when physical scientists first recognized that…
