A three-dimensional box that mimics an underwater ocean scene teaches players about an underwater fossil fuel resource in a new Japanese board game. Methane hydrate is a natural energy resource buried deep below the ocean floor surrounding Japan. This mixture of methane and ice, once extracted, can be converted into methane gas, a viable energy source. Chiharu Aoyama, an ocean resources professor at the Tokyo University of Marine Science and Technology, suspects Japan’s citizens do not know about this natural resource. In 2016, Aoyama worked with Daiki Aoyama, a family member and game hobbyist, to design a board game to raise awareness about methane hydrate among Japanese people of all ages.

High-resolution radar and night vision cameras may help scientists protect bats from untimely deaths at wind farms, according to new research. Researchers are using these technologies to provide more specific details about the number of bats killed by wind turbines in Iowa.

The surface waters of Lake Dillon, a mountain reservoir that supplies water to the the Denver area, have warmed by nearly 5 degrees Fahrenheit (2.5 degrees Celsius) in the last 35 years, which is twice the average warming rate for global lakes. Yet surprisingly, Dillon does not show adverse environmental changes, such as nuisance algal blooms, often associated with warming of lakes.

Seasonal snow and ice accumulation cause glaciers in the Cascade Range mountains to grow a little every winter and melt a little every summer. This annual melt provides water for much of the Pacific Northwest, which includes Washington, Oregon, Idaho and parts of Montana. Inhabitants of the region utilize this water for drinking, crop irrigation, generating hydroelectric power and other uses. Glacier melt provides supplementary water when less snowmelt is available, alleviating drought conditions or other impacts of dry periods.

The 2008 Wenchuan earthquake in Sichuan, China killed tens of thousands of people and left millions homeless. Approximately 20,000 deaths — nearly 30 percent of the total — resulted not from the ground shaking itself but from landslides the quake triggered. A new model can help experts address such risks by estimating the likelihood of landslides that will be caused by earthquakes anywhere in the world. The estimates can be available within minutes, providing potentially life-saving information to people who are affected by earthquakes and the agencies and organizations charged with responding to them.

The flow of water that supports hydro-electric and irrigation infrastructure in the mountain regions of Nepal and India is regulated by hundreds of large icy ponds on the surface of some of the world’s highest glaciers, scientists have revealed.

A new study has found that dust, not spring warmth, controls the pace of spring snowmelt that feeds the headwaters of the Colorado River.

Scientists have developed cartograms — maps that convey information by contorting areas — to visualize the risks of climate change in a novel way.

Freshwater streams and rivers naturally clean up some forms of pollution originating from urban and agricultural areas, but increased storm intensity reduces this ability.

Groundwater recharge in the Western U.S. will change as the climate warms–the dry southern regions will have less and the northern regions will have more, according to new research.
