Hundreds of leaders and thousands of climate scholars from around the globe will gather in Glasgow, Scotland, for COP26, the 2021 United Nations Climate Change Conference, from Oct. 31 to Nov. 12.

Most experts believe this year’s meeting — the biggest climate summit since the Paris Agreement was signed…

Lead Remediation Efforts Show Promise for Safe Drinking Water in New York City Public Schools
Oct. 21, 2021
Written by Riis L. Williams for the School of Public and International Affairs

Since the water crisis in Flint, Michigan, many states have passed legislation requiring public schools to assess and treat lead in their drinking water. Two Princeton University researchers examined the efforts by New York City, the largest school district in the country, to determine the efficacy of…

New platform speeds up effort to turn crops into fuel
Aug. 30, 2021
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…

The Arctic Ocean’s deep past provides clues to its imminent future

Written by Liz Fuller-Wright, Office of Communications

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 forests may cool the planet more than thought
Aug. 9, 2021
Written by By Liana Wait for the High Meadows Environmental Institute

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
July 28, 2021
Written by Liz Fuller-Wright, Office of Communications

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…

Exhaustive comparison of continental-scale hydrological models ensures better management of water resources
July 7, 2021
Written by Morgan Kelly, High Meadows Environmental Institute

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…

How we measure biodiversity can have profound impacts on land-use
June 28, 2021
Written by Liana Wait, Princeton School of Public and International Affairs

The world’s human population is expanding, which means even more agricultural land will be needed to provide food for this growing population. However, choosing which areas to convert is difficult and depends on agricultural and environmental priorities, which can vary widely.
