Princeton geosciences professor Michael Bender, an internationally recognized authority on paleoclimate, provides a concise, comprehensive, and sophisticated introduction to the subject.
Co-author Adam Wolf, from Princeton University's Department of Ecology and Evolutionary Biology, explained: "On today's planet, the supply of nutrients in the soil is determined by river deposits or nutrients that are airborne." Researchers say the model can also forecast the consequences of losing today's large animals. But Dr. Wolf added that their study suggested that things were once very different: "We believe that large animals once
DAVIS — Two species of bacteria living on the ocean floor have teamed up in a unique symbiotic relationship to form a critical link in the Earth’s nitrogen cycle, reports a research team that includes two University of California, Davis, microbiologists. The scientists, led by researchers affiliated with the University of Southern California, will publish their findings about the novel bacterial partnership Aug. 8 in the journal Nature. At the heart of the study are the long, thin,
A study of sed­i­ment cores col­lected from the deep ocean sup­ports a new expla­na­tion for how glac­ier melt­ing at the end of the ice ages led to the release of car­bon diox­ide from the ocean.
Environmental awareness comes in many forms. Often, it is shaped by an understanding of science or public policy, but it also can be informed by religion.  Rarely, however, do all three of these perspectives intersect at once—and that is the challenge two Yale University professors, Mary Evelyn Tucker and John Grim, have been addressing for the past three decades. Tucker and Grim’s course “Religion, Ecology, and Cosmology” illustrates how religion, spirituality,
When the worst drought in 60 years hit America’s corn belt this summer, many people wondered if it was caused by climate change.
An enhanced approach to capturing changes on the Earth's surface via satellite could provide a more accurate account of how ice sheets, river basins and other geographic areas are changing and why.
Yes, science is being distorted. But, much more dangerous, it is being rejected.
The Princeton Environmental Institute (PEI) has announced $1.1 million in new awards to support climate and energy research at Princeton University.
The oscillations during the past 2.5 million years between ice ages and interglacials were probably triggered by orbital changes, but the observed amplitude and timing of these climate cycles still awaits a full explanation. One notable correlation links lower partial pressure (or concentration) of CO2 with ice ages: changes in CO2 concentration may cause some of the ice-age cooling, but what causes the loss of CO2 is unknown. Daniel Sigman, Mathis Hain and Gerald Haug review the evidence in sup
We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular. All citizens should understand some basic scientific facts.
A new report should spur public debate about how science and technology can best sustain the earth while furthering the goals of humanity, according to Robert Socolow, one of 18 maverick thinkers convened by the National Academy of Engineering (NAE) to map the greatest technological challenges of this century.
