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…
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…
Princeton University senior meteorologist Syukuro "Suki" Manabe has been awarded the 2021 Nobel Prize in physics "for the physical modeling of Earth’s climate, quantifying variability and reliably predicting global…
A faculty panel has been established to provide impartial scholarly advice as the University works to develop and implement its dissociation process to advance action on climate change.
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…
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…
