Written by Scott Lyon, School of Engineering and Applied Science

Princeton researchers have developed a new way to make fuel from cellulose—Earth's most abundant organic compound, found in all plant cells—speeding up a notoriously slow chemical process and in some cases doubling energy yields over comparable methods.

Their platform uses a recently developed cellulose emulsion that makes it easier…

As the North Pole, the Arctic Ocean and the surrounding Arctic land warm rapidly, scientists are racing to understand the warming’s effects on Arctic ecosystems.

With shrinking sea ice, more light reaches the surface of the Arctic Ocean. Some have predicted that this will lead to more plankton, which in turn would support fish and…

Planting trees and replenishing forests are among the simplest and most appealing natural climate solutions, but the impact of trees on atmospheric temperature is more complex than meets the eye.

One question among scientists is whether reforesting midlatitude locations such as North America or Europe could in fact make the planet…

'Less than 1% probability' that Earth’s energy imbalance increase occurred naturally, say Princeton and GFDL scientists

Sunlight in, reflected and emitted energy out. That’s the fundamental energy balance sheet for our planet. If Earth’s clouds, oceans, ice caps and land surfaces send as much energy back up to space as the sun shines down on us, then our planet maintains equilibrium.

But for decades, that system has been out of balance. Sunlight…

While Earth’s freshwater resources are finite, the challenge of effectively and sustainably managing them as we head into a warmer future with a growing human population means keeping tabs on a seemingly endless network of above- and below-ground waterways.

For the United States, two enormous models have been developed that capture…
