Thirty Years Of Unique Data Reveal What’s Really Killing Coral Reefs

healthy Elkhorn corals

Coral reefs are considered one of the most threatened ecosystems on the planet and are dying at alarming rates around the world. Scientists attribute coral bleaching and ultimately massive coral death to a number of environmental stressors, in particular, warming water temperatures due to climate change. A study published in the international journal Marine Biology, …

Carbon Dioxide Absorption By Boron Nitride Foam

boron nitride foam

A light foam created from two-dimensional sheets of hexagonal boron nitride by materials scientists at Rice University absorbs carbon dioxide. They discovered freeze-drying hexagonal-boron nitride (h-BN) transformed it into a macro-scale foam that disintegrates in liquids. But adding a bit of polyvinyl alcohol (PVA) into the mix turned it into a far more robust and …

Climate Predictions And Reality Are Beginning To Converge

climate prediction

Scientists studying climate change have long debated just how much hotter Earth will become with given levels of greenhouse gas emissions. Models predicting this “climate sensitivity” number may be closer to the observed reality than some previously thought, according to a new University of Washington study. Observations in the past decade appeared to suggest a …

Temperate Broadleaf Forests More Susceptible To Heat Stress

broadleaf forest

Temperate broadleaf forests, such as the stands of red oak common in New England, absorb more carbon than expected along their edges, but are more susceptible to heat stress. Over centuries, as humans have cleared fields for farms, built roads and highways, and expanded cities, we’ve been cutting down trees. Since 1850, we’ve reduced global …

The Agulhas Current Is Widening, Not Strengthening

Agulhas Current

The Indian Ocean’s Agulhas Current is becoming wider rather than stronger, according to a new study by University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers. The findings have important implications for global climate change. The study suggests that intensifying winds in the region may be increasing the turbulence of the current, …

Early Earth’s Atmosphere Could Have Been Half As Thick As Today

Early Earth

Did the young Earth really have a more dense atmosphere, as the current theory goes? Researchers recently used bubbles trapped in rocks to demonstrate that the air 2.7 billion years ago exerted at the most only half the pressure of today’s atmosphere. According to a study published this week in the journal Nature Geoscience, the …
