Tides don’t always flush water out to sea, study shows

By area, tidal flats make up more than 50 percent of Willapa Bay in southwest Washington state, making this more than 142-square-mile estuary an ideal location for oyster farming. On some parts of these flats, oysters grow well, filling their shells with delicacies for discerning diners. But according to experienced oyster farmers, oysters raised in other parts of Willapa Bay don’t yield as much meat. (more…)

Why Everyone Should Be The Global Warming Skeptic?

Global warming is the long-term rise in the average temperature of the Earth’s climate system. It is a major aspect of current climate change, and has been demonstrated by direct temperature measurement and by measurements of various effects of the warming.The term commonly refers to the mainly human-caused increase in global surface temperature and its projected continuation.Human influence has been the dominant cause of the observed warming since the mid-20th century. The largest human influence has been the discharge of greenhouse gases such as carbon dioxidemethane, and nitrous oxide. (more…)

Freiburger Hydrologin zeigt mit neuen Zahlen, wie sinkende Grundwasserspiegel die Vitalität der Ökosysteme bedrohen

Grundwasser ist die weltweit größte Süßwasserressource und von entscheidender Bedeutung für die Produktion von Nahrungsmitteln. Durch den konstanten Anstieg der Grundwasserförderung in den vergangenen Jahrzehnten ist der Grundwasserspiegel mancherorts bereits gesunken. (more…)

Solar cells (like people!) work better with caffeine

In UCLA-led study, perovskite-based devices benefit from the strong bond between lead and the same chemical found in coffee and tea

Scientists at the California NanoSystems Institute at UCLA have found that caffeine improves the stability of materials under heat – a property known as thermal stability — of perovskite solar cells, which could someday replace traditional silicon-based solar cells. (more…)

North Carolinian boats are now fishing off New Jersey’s coast

As the oceans warm in response to climate change, fishing boats in the Mid-Atlantic that focus on only one or two species of fish are traveling more than 250 miles farther north than they did 20 years ago, while others catching a wide diversity of species have not changed fishing location, reported Talia Young, a postdoctoral research associate in ecology and evolutionary biology at Princeton.

The Environmentally Friendly Way to Dispose of Your Mattress

Discarded mattresses have long been a thorn in the side of garbage collectors; over 300 mattresses are thrown out every day to make their way to landfills. This is a shame, because while old mattresses take up hundreds of thousands of square miles in landfills each year, many of their parts including the metal springs, fabric, and wood can be reused. Recycling a mattress can be as beneficial as recycling the metals found in e-waste. (more…)

New technique can show links between prey and microplastics

A brand new method has been developed by scientists at Plymouth Marine Laboratory (PML) and the University of Exeter, in collaboration with Abertay University and Greenpeace Research Laboratories, to investigate links between top predator diets and the amount of microplastic they consume through their prey, offering potential insights into the exposure of animals in the ocean and on land to microplastics.

Archiv des Klimawandels

Forscherteam präsentiert in Nature Communications die erste globale Analyse von Höhlentropfwasser

Die in Karsthöhlen vorkommende Tropfsteine Stalagmiten und Stalaktiten geben wertvolle Hinweise auf das bisherige Erdklima. Wissenschaftlerinnen und Wissenschaftler benutzen die Zusammensetzung von Sauerstoffisotopen in Stalagmiten als Klimaarchiv, das wichtige Informationen zu früheren Klimawandeln gespeichert hat. (more…)
