Long-term data show a recent acceleration in chemical and physical changes in the ocean

(Bermuda Institute of Ocean Sciences) New research published in Nature Communications Earth & Environment uses data from two sustained open-ocean hydrographic stations (Hydrostation ‘S’ and the Bermuda Atlantic Time-series Study) in the North Atlantic Ocean near Bermuda to demonstrate recent changes in ocean physics and chemistry since the 1980s. The study shows decadal variability and recent acceleration of surface warming, salinification, deoxygenation, and changes in carbon dioxide (CO2)-carbonate chemistry that drives ocean acidification.

Astronomers identify 24 possible superhabitable worlds

Are there worlds out there – orbiting distant stars – even better suited for life than Earth? Might they be older, larger, warmer, wetter and with longer-living stars? Now astronomers have identified 24 possible superhabitable worlds.

World’s longest-running carbon dioxide measurement receives continuation funding

(Schmidt Ocean Institute) The Keeling Curve carbon dioxide measurement-the long-term atmospheric measurement that alerted the world to human-induced climate change- will receive $1 million in continuation funding from philanthropists Eric and Wendy Schmidt, Scripps Institution of Oceanography at the University of California San Diego announced today. In addition, the couple’s Schmidt Ocean Institute awarded a separate $450,000 grant to the university to support complementary ocean acidification measurements in the Atlantic and Pacific.

How leaves reflect light reveals evolutionary history of seed plants

The way leaves reflect light, known as plant reflectance spectra, can illuminate the evolutionary history of seed plants, according to researchers. The researchers found that by measuring the light spectrum reflected by leaves, they can identify the plant and its chemistry, evolution and place in the tree of life.

New global temperature data will inform study of climate impacts on health, agriculture

A new data set provides high-resolution, daily temperatures from around the globe that could prove valuable in studying human health impacts from heat waves, risks to agriculture, droughts, potential crop failures, and food insecurity.

Darwin’s theory about coral reef atolls is fatally flawed

Charles Darwin’s 1842 theory about the formation of ring-shaped reefs, called atolls, is incorrect, but ‘it’s so beautiful, so simple and pleasing’ that it still appears in textbooks and university courses, said a marine geologist. The accurate description is more complicated, and biologists are hoping to set the record straight.
