CO-EVOLUTION OF PRIMITIVE METHANE-CYCLING ECOSYSTEMS AND EARLY EARTH, ITS ATMOSPHERE AND CLIMATE

 

22 mai 2020

 

Biological activity may deeply influence Earth’s climate. But all along its long history, this influence is still misunderstood. An interdisciplinary team, financed by the PSL project “Origins and Conditions for the Emergence of Life” (OCAV) and composed of researchers from the Paris Observatory, the Biology Institute of ENS (Ecole Normale Supérieure) and UMI iGLOBES at the University of Arizona, show that on primitive Earth, the evolution of methane cycling microbes influenced the stability of the climate early on, the glacial cycles, and therefore the planet’s habitability. This new approach, coupling atmospheric composition modelization over a long-term period with the evolution of ecosystems, opens new perspectives in the study of the habitability of planets and their moons, and of terrestrial exoplanets. 

 

The full article, co-written by Boris Sauterey, Benjamin Charnay, Antonin Affholder, Stéphane Mazevet, and Regis Ferriere? will be published shortly in Nature Communications.

ARIZONA'S GROUNDWATER MANAGEMENT ACT AT 40: TACKLING UNFINISHED BUSINESS

Kirsten Engel, Professor of Law at the University of Arizona, Esther Loiseleur and Elise Drilhon, both visiting interns at iGLOBES in the summer of 2019 published an article in the Arizona Journal of Environmental Law & Policy, 2020 Spring issue.

 

The 1980 Groundwater Management Act was created to control the rapidly decreasing groundwater of the state, but despite the extraordinary legislation, it fell short of its intended purpose, creating serious groundwater issue and impacting Arizona's ecosystem.

Forty years later, what should be done? Read the article...
