Capturing carbon at the smokestack is a promising way to combat climate change, but the majority of Americans are unfamiliar with the technology, according to a new study from Princeton University.

“It’s a signal that more communication is necessary to the general public,” said Elke Weber, the senior author of the study, who is the…

The two years Princeton senior Joe Kawalec spent studying the natural camouflage of the ubiquitous downy woodpecker oddly enough began and ended the same way — tracing the outlines of birds.

In between, he observed patterns in tree bark through

Research meets the challenge of measuring urban carbon emissions

Written by Morgan Kelly, High Meadows Environmental Institute

As more people call for action against climate change, more than 500 cities worldwide have established low-carbon and net-zero carbon goals intended to substantially reduce greenhouse gas emissions in the coming decades.

But a major challenge to these decarbonization plans is the lack of a consensus on how to measure urban carbon…

Simple atmospheric dynamics foretell dangerously hot future for the tropics

Written by Morgan Kelly, High Meadows Environmental Institute

Extreme heat is among the most concerning and potentially deadly effects of climate change, especially for the rapidly growing and urbanizing populations living in the tropics. Yet, climate models tend to be unclear when projecting how high temperatures will climb on a regional scale, and often overlook the point at which heat is a risk to…

Princeton University researchers have shown that an often-overlooked cooling technology can enable more ventilation in buildings around the world while substantially decreasing energy costs.

In a study published in a COVID-19 edition of the journal Applied Energy, the researchers showed that radiant systems – which control the…

Princeton University will undergo one of the most extensive building programs in its history over the next decade — adding some 3 million square feet in new construction to house more students, expand research facilities, and…

Low-cost solar-powered water filter removes lead, other contaminants
March 31, 2021

A new invention that uses sunlight to drive water purification could help solve the problem of providing clean water off the grid.

The device resembles a large sponge that soaks up water but leaves contaminants – like lead, oil and pathogens – behind. To collect the purified water from the sponge, one simply places it in sunlight. The…

The heavy snowfalls and frigid days of this past winter in New Jersey let Princeton sophomore Grace Liu finally experience the Northeastern winter she’d only imagined growing up in her Florida hometown of palm trees and sandy beaches…

High end of climate sensitivity in new climate models seen as less plausible
March 3, 2021
Author
Written by Morgan Kelly, High Meadows Environmental Institute

A recent analysis of the latest generation of climate models — known as a CMIP6 — provides a cautionary tale on interpreting climate simulations as scientists develop more sensitive and sophisticated projections of how the Earth will respond to increasing levels of carbon dioxide in the atmosphere.

Despite sea-level rise risks, migration to some threatened coastal areas may increase

Author
Written by Keely Swan, Center for Policy Research on Energy and the Environment

In coming decades as coastal communities around the world are expected to encounter sea-level rise, the general expectation has been that people’s migration toward the coast will slow or reverse in many places.

However, new research co-authored by Princeton University scholars shows that migration to the coast could actually…
