Maintaining Mountain Snowpacks Essential for Preserving Valuable Freshwater Resource
Snowcapped mountains generate mountain water runoff and snowmelt, which flow down to streams, rivers, lakes, and oceans. Around a quarter of the world depends on these natural “water towers” to replenish downstream reservoirs and groundwater aquifers for urban water supplies, agricultural irrigation, and ecosystem support. Carbon mitigation strategies are needed to maintain snowpack throughout the Americas.

Zaporizhzhia: What Would Be the Consequences of an Accident?
Although it’s impossible to say for sure what consequences an accident at Ukraine’s Zaporizhzhia nuclear power plant might have on human health in the environment nearby, experts can make some predictions.

The Benefits of Integrating Electric Vehicles into Electricity Distribution Systems
As the cost of EVs continues to decrease, the industry matures, incentives grow, and charging infrastructure improves, EVs could make up the vast majority of vehicles on the road in 2050. Many studies have looked at how increased electricity demand will affect the bulk power system in the United States, but public analysis of the impacts on the distribution system has been less prevalent.

Fukushima Fears Notwithstanding, Japan Still Depends on Nuclear Power
The 2011 Fukushima disaster helped seal the fate of nuclear power in Japan, or so it seemed. Tokyo now plans to extend the life of its nuclear plants and is considering new smaller, safer reactors.

Fossil Fuel Past, Green Future: Abandoned Wells May Offer Geothermal Power
Tapping into abandoned oil and gas wells in Pennsylvania, products of the state’s long history of energy extraction — could provide a future source of affordable geothermal energy. Regulators estimate hundreds of thousands of oil and gas wells have been drilled in the state, many before modern regulations, and lost over time in fields, forests and neighborhoods.

More Heat, Humidity as a Result of Climate Change Challenge Power Grid
Increasing heat and humidity, and the intensification of more-frequent extreme weather events, are a few of the challenges climate change poses for the nation’s power grid. A new study recommends adaptations to protect grid reliability, resiliency.

Sea-Level Rise “May Cross Two Meters by 2100”
Land subsidence could worsen sea-level rise effects in the Asia Pacific region. Most islands in the Pacific are subsiding, presenting a challenge to infrastructure. Pacific Island Countries have low adaptative capacity to climate change.

A Decade After Sandy, Manhattan’s Flood Barrier Is Finally in Sight — Sort of
In the wake of the October 2012 Superstorm Sandy, an ambitious project, called the “Big U,” was launched, aiming to wrap the island of Manhattan in miles of berms and artificial shorelines, creating a huge grassy shield that would both increase urban green space and defend the city from storm surge. The “Big U” shows how climate adaptation can succeed. It also shows how hard it is.

Software Suite Will Bolster Defenses for Soft Targets
Anyone who has ever gone to a major sporting event or concert, taken public transportation, even visited a farmer’s market on a brisk weekend morning, has likely benefitted from soft-target physical security—and perhaps didn’t even know it. DHS S&T is working developing a suite of decision-support software known as Special Event Planning Tools (SEPT) to help those in charge of securing soft targets.

Texas’ Plan to Provide Water for a Growing Population Ignores Climate Change
Texas’ biggest single solution to providing enough water for its soaring population in the coming decades is using more surface water, including about two dozen new large reservoirs. But climate change has made damming rivers a riskier bet.

Hydropower Delivers Electricity, Even During Lengthy Droughts
The megadrought in the Southwestern United States is the driest—and longest—in the last 1,200 years, depleting water reservoir levels to critically low levels over the past 22 years. Droughts particularly impact hydroelectric power dams as well as some thermoelectric power plants that require large amounts of water for cooling. But a new report suggests that the relationship between drought and hydroelectric power is more nuanced than it might seem. Drought-strained hydropower sustains 80 percent average power generation capacity.
