High end of climate sensitivity in new climate models seen as less plausible

March 3, 2021 ・ Morgan Kelly

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…

Princeton researchers at forefront of national plans for technological and social transition to net-zero emissions

February 3, 2021 ・ Morgan Kelly

Scientists and research based at Princeton University played a critical role in a new national report that investigates the technology, policy and societal dimensions of accelerating decarbonization in the United States. The National Academies of Sciences, Engineering and Medicine announced…

Carbon-chomping soil bacteria may pose hidden climate risk

January 27, 2021 ・ Molly Sharlach

Much of the Earth’s carbon is trapped in soil, and scientists have assumed that potential climate-warming compounds would safely stay there for centuries. But Princeton research supported by the High Meadows Environmental Institute (HMEI) shows that carbon molecules can potentially…

Data-Driven Model Provides Projections of a 21st Century Urban Climate

January 4, 2021 ・ Lois E. Yoksoulian and B. Rose Huber

Cities occupy about only 3% of the Earth’s total land surface, but they bear the burden of the human-perceived effects of global climate change. Yet, current global climate models are set up mainly for big-picture analysis, leaving urban areas poorly…

Getting U.S. to net-zero emissions by 2050 will take massive, but affordable, coordination

December 15, 2020 ・ Molly A. Seltzer

With a massive, nationwide effort the United States could reach net-zero emissions of greenhouse gases by 2050 using existing technology and at costs aligned with historical spending on energy, according to a study led by Princeton researchers. The new “Net-Zero…

How plants compete for underground real estate affects climate change and food production

December 3, 2020 ・ Liana Wait

You might have observed plants competing for sunlight — the way they stretch upwards and outwards to block each other’s access to the sun’s rays — but out of sight, another type of competition is happening underground. In the same…

Princeton, PEI researchers join $1M NSF effort to model nation’s groundwater

September 28, 2020 ・ Morgan Kelly

Researchers from Princeton will help lead a $1 million project funded by the National Science Foundation (NSF) that will use artificial intelligence to simulate the nation’s natural groundwater system in an effort to improve water management and help people better…

CMI Best Paper Awards recognize postdoc, graduate student published research

May 5, 2020 ・ Holly Welles

The Carbon Mitigation Initiative (CMI) recognized Jane Baldwin, a past postdoctoral fellow in the Princeton Environmental Institute (PEI), and Samantha Hartzell, a graduate student in civil and environmental engineering, at the CMI Annual Meeting for outstanding published research. Baldwin received…

Expansion, environmental impacts of irrigation by 2050 greatly underestimated

May 4, 2020 ・ Joseph Albanese

The amount of farmland around the world that will need to be irrigated in order to feed an estimated global population of 9 billion people by 2050 could be up to several billion acres, far higher than scientists currently project,…
