Deep heat beneath the United States traced to ancient rift with Greenland

University of Southampton
Peer-Reviewed Publication

Large region of unusually hot rock beneath the Appalachian Mountains in teh USA is linked to the splitting of Greenland and North America 80 million years ago.This finding challenges the long-held belief that the NAA resulted from North America separating from Northwest Africa 180 million years ago.

Why animals are a critical part of forest carbon absorption

Massachusetts Institute of Technology
Peer-Reviewed Publication

Following deforestation, tropical forests with healthy populations of seed-dispersing animals can absorb up to four times more carbon than similar forests with fewer seed-dispersing animals, according to an MIT study.

Cosmic dust opens window on ancient atmosphere

University of Göttingen
Peer-Reviewed Publication

Since the beginning of Earth's history, tiny particles of rock and metal from space have been hitting our planet. On clear nights, we can even see their traces as shooting stars. Trapped in layers of rock, these micrometeorites can remain preserved for billions of years. An international research team led by the University of Göttingen and including the Open University, the University of Pisa, and Leibniz University Hannover has developed a method that allows them to reconstruct the atmosphere of the past using fossilized micrometeorites. The results were published in Communications Earth & Environment.

How climate shapes soil fungal traits

Dartmouth College
Peer-Reviewed Publication

Many soil microbes play a vital role in ecosystems, as they help plants access nutrients and water and assist in stress tolerance such as during drought and to defend against pathogens. One such group of soil microbes are arbuscular mycorrhizal, aka AM, fungi, which are associated with the roots of approximately 70% of plant species on land. new Dartmouth-led study reports on how global climate conditions affect AM fungal spore traits and the species biogeographic patterns. The results are published in the Proceedings of the National Academy of Sciences.

Research improves accuracy of climate models – particularly for extreme events

North Carolina State University
Peer-Reviewed Publication

Researchers have devised a new machine learning method to improve large-scale climate model projections and demonstrated that the new tool makes the models more accurate at both the global and regional level. This advance should provide policymakers with improved climate projections that can be used to inform policy and planning decisions.
