Without major efforts to rebuild Louisiana’s wetlands, particularly in the westernmost part of the state, there is little chance that the coast will be able to withstand the accelerating rate of sea-level rise, a new Tulane University study concludes.

The study by researchers in Tulane’s Department of Earth and Environmental Sciences and published in the open-access journal Nature Communications shows that the rate of sea-level rise in the region over the past six to 10 years amounts to half an inch per year on average.

More than 2.4 billion years ago, Earth’s atmosphere was inhospitable, filled with toxic gases that drove wildly fluctuating surface temperatures. Understanding how today’s world of mild climates and breathable air took shape is a fundamental question in Earth science.

New research from the University of Maryland, the University of St. Andrews, NASA’s Jet Propulsion Laboratory, the University of Leeds and the Blue Marble Space Institute of Science suggests that long ago, Earth’s atmosphere spent about a million years filled with a methane-rich haze. This haze drove a large amount of hydrogen out of the atmosphere, clearing the way for massive amounts of oxygen to fill the air. This transformation resulted in an atmosphere much like the one that sustains life on Earth today.

Massive coastal flooding in northern Europe that now occurs once every century could happen every year if greenhouse gas emissions continue to rise, according to a new study.

New projections considering changes in sea level rise, tides, waves and storm surge over the 21st century find global warming could cause extreme sea levels to increase significantly along Europe’s coasts by 2100. Extreme sea levels are the maximum levels of the sea that occur during a major storm and produce massive flooding.

Researchers at Caltech and Lawrence Berkeley National Laboratory (Berkeley Lab) have—in just two years—nearly doubled the number of materials known to have potential for use in solar fuels.

They did so by developing a process that promises to speed the discovery of commercially viable solar fuels that could replace coal, oil, and other fossil fuels.

A new study by researchers at Columbia University’s Mailman School of Public Health showed that B vitamins may play a critical role in reducing the impact of air pollution on the epigenome, further demonstrating the epigenetic effects of air pollution on health. This is the first study to detail a course of research for developing interventions that prevent or minimize the adverse effects of air pollution on potential automatic markers. The results are published online in the journal PNAS.
