There has been a massive boom in wind power capacity both in Europe and worldwide. In 2015 global installed capacity was around 350 gigawatt (GW), with 135 GW installed in Europe, distributed across some 87,000 wind turbines. Wind power now provides a bigger share (13 percent) of electricity than nuclear power stations. In countries such as Spain, Denmark and Germany, the amount of wind power already installed is in theory enough to cover nationwide demand for electricity under ideal conditions, i.e. maximum wind power output and low consumer demand.

New research suggests that Africa has gradually become wetter over the past 1.3 million years -- instead of drier as was thought previously.
The research from Berke, assistant professor in the Department of Civil and Environmental Engineering and Earth Sciences at the University of Notre Dame and Environmental Change Initiative affiliate, suggests that Africa has gradually become wetter over the past 1.3 million years -- instead of drier as was thought previously. The findings shine new light on the "savanna hypothesis," which held that humans in Africa as a whole migrated to grasslands due to a changing climate.
The sediment samples that Berke studied came from Lake Malawi in southeast Africa, whereas data used for the savanna hypothesis came from the north. Her research suggests that climate conditions across Africa may have been more variable than once thought.

The specific cultural values of a country may determine whether concern about environmental issues actually leads individuals to engage in environmentally friendly behaviors, according to the new research published in Psychological Science, a journal of the Association for Psychological Science.
The findings suggest that individual concern is more strongly associated with motivation to act in countries that espouse individualistic values, while social norms may be a stronger motivator in collectivistic societies.

A new marine biodiversity study in one of the largest Marine Protected Areas in the world reveals the impact of environmental change on subantarctic seabed animals and answers big questions about the extent of South Georgia's ice sheet during the Last Glacial Maximum around 20,000 years ago.
Reporting this week in the Journal of Biogeography researchers at British Antarctic Survey (BAS) describe how colonies of seabed creatures, such as sea sponges - that play an important role in absorbing and storing carbon from the atmosphere - can take thousands of years to recover from major glaciation events.

What if you could have your packaging and eat it too? We’ve seen rice paper packaging on Japanese candies, but edible plastic? Thanks to researchers at the USDA, it’s not too far in the future.
And it’s not just an edible and environmentally-friendly plastic alternative; it’s actually better at keeping food fresh than petroleum-based plastics. It’ll be a few years before you see the material on shelves — don’t start chomping down just yet — but it represents a big revolution in the way we view food packaging.

As a nutritional trace element, selenium forms an essential part of our diet. In collaboration with the International Agency for Research on Cancer, researchers from Charité - Universitätsmedizin Berlin have been able to show that high blood selenium levels are associated with a decreased risk of developing liver cancer. In addition to other risk factors, the study also examines in how far selenium levels may influence the development of other types of cancer. Results from this study have been published in the American Journal of Clinical Nutrition. *

Methane is stored under the sea floor, concentrated in form of hydrates, crystalline ice structures that stay stable under high pressure and in low temperatures. Several studies suggest that as the ocean warms, the hydrates might melt and potentially release methane into the ocean waters and atmosphere.
Several studies suggest that as the ocean warms, the hydrates might melt and potentially release methane into the ocean waters and atmosphere. This potent climate gas is profusely leaking from the seafloor in an area offshore western Svalbard, which is close to the gas hydrate stability zone.
There, scientists have discovered over 250 methane flares in water depths from 90 to 240 meters.
“Previous studies indicate that these seeps could be linked to gas hydrate dissociations. We suspected that dissociation of gas hydrate is not the primary control on seafloor methane seepage. We suggest that there is a strong lithological control on methane seepage.” says Dr. Giuliana Panieri, scientist at CAGE.

As a multiyear drought grinds on in the Southwestern United States, many wonder about the impact of global climate change on more frequent and longer dry spells. As humans emit more carbon dioxide into the atmosphere, how will water supply for people, farms, and forests be affected?
A new study from the University of California, Irvine and the University of Washington shows that water conserved by plants under high CO2 conditions compensates for much of the effect of warmer temperatures, retaining more water on land than predicted in commonly used drought assessments.
According to the study published this week in the Proceedings of the National Academy of Sciences, the implications of plants needing less water with more CO2 in the environment changes assumptions of climate change impacts on agriculture, water resources, wildfire risk, and plant growth.
