Future Widespread Water Shortage Likely in U.S. - Science in the News - 0 views

DRIVER-INFRASTRUCTURE-SCARCITY-POLITICS By 2071, nearly half of the 204 freshwater basins in the United States may not be able to meet the monthly water demand. These model projections, recently published in the journal Earth's Future, are just one preliminary component of the upcoming Resources Planning Act (RPA) Assessment expected to be published next year. In 1974, congress required that this assessment of US renewable resources be published every 10 years. Conducted by the U.S. Forest Service, the research describes two causes for the projected shortages. The first is that the U.S. will simply have more people. Despite that the average American is using less water, population growth is still expected to increase water demand across most of the country. Second, the water supply itself is expected to decrease. Projected climate change affects both rain patterns and temperatures. While rainfall is expected to increase in some parts of the US, the southern Great Plains and parts of the South won't be so lucky. The water basins rely on rainfall to feed the rivers and tributaries that flow into them. Separately, more water will evaporate from reservoirs and streams as the climate gets warmer, further chipping away at the water supply. Around 50 years from now, many U.S. regions may see water supplies reduced by a third of their current size, while demand continues to increase.

DRIVERS-SCARCITY-INFRASTRUCTURE This study estimates the likelihood of water shortages over the remainder of the 21st century in 204 watersheds covering the contiguous United States. The estimates are based on monthly projections of water demand and renewable water supply in light of population growth and climate change, taking into account water storage and transbasin diversion capacities. The study then examines several possible adaptations to projected shortages, including water withdrawal efficiency improvements, reservoir storage enhancements, demand reductions, instream flow reductions, and groundwater depletion. Results provide a broad measure of the relative efficacy of the adaptation measures and show when and where the measures are likely to be helpful.
Ozone Water Treatment for Well Water: The 6 Things You Need to Know - 0 views
-
DRIVER-WATER TREATMENT TECHNOLOGY Ozone water treatment oxidizes iron, manganese, and sulfur in your well water to form insoluble metal oxides or elemental sulfur. These insoluble particles such as rust, are then removed by filtration which is typically activated carbon, manganese dioxide, or other media such as filter sand. Ozone is much faster at killing bacteria and oxidizing iron and manganese compared to chlorine or peroxide. One advantage for home use is that ozone is quite unstable and will degrade over a time frame ranging from a few seconds to 30 minutes.

DRIVER-FUNDING-INFRASTRUCTURE FUNDING INFRASTRUCTURE: The nationwide need for investment in water and wastewater infrastructure continues to far outpace the amount of funding that is available at all levels of government and the United States has an estimated need between $400 and $600 billion over the next 20 years for safe drinking water and wastewater treatment infrastructure. One of the primary sources of federal funding for drinking water and wastewater infrastructure are the highly successful, but chronically underfunded, Safe Drinking Water and Clean Water State Revolving Loan Fund (SRF) programs. Modernizing and replacing aging water infrastructure may be the single largest public works endeavor in our nation's history. The U.S. Environmental Protection Agency's Clean Water and Drinking Water Infrastructure Gap Analysis found a $540 billion gap between current spending and projected needs for water and wastewater infrastructure (combined) over 20 years. Other public studies conducted by the Government Accountability Office (GAO) and the Congressional Budget Office (CBO), and a private study produced by AGC partner, the Water Infrastructure Network, have similarly estimated the nation?s water infrastructure needs to range between $400 and $600 billion over a 20-year period.

Engineers Solve Major Problem in Quantum Computer Design - 0 views
-
Quantum engineers from UNSW Sydney have solved a problem that has baffled scientists for decades: How to reliably control millions of qubits in a silicon quantum computer chip without wasting valuable space with extra wiring. This issue had been a significant roadblock to the development of a full-scale quantum computer, but it has now been overcome thanks to the engineers who developed a new technique capable of controlling millions of spin qubits simultaneously. Quantum computing will open the door to solving a whole new set of challenges requiring intense computational power.
The Futures of Congress: Scenarios for the US2050 Project - 0 views

This paper uses a scenario-based approach to understand how Congress might function in 2050. At present, Congress appears to be underperforming due to high levels of polarization, hyperpartisanship, and gridlock. Notwithstanding these challenges, Congress will need to address several big and complex issues over the next three decades, including the demographic transformation of the United States into a majority-minority nation, the looming fiscal challenges facing the federal government, widespread automation in the economy, climate change, more diffuse and dangerous patterns of global conflict, and the rapidly evolving media and communications technology environment.

CSIS's Risk and Foresight Group created four plausible, differentiated scenarios to explore the changing geopolitical landscape of 2025-2030, including the potential lasting first- and second-order effects of Covid-19. The scenarios center on the relative power and influence of the United States and China and the interaction between them, along with detailed consideration of other major U.S. allies and adversaries within each of four worlds. Each scenario narrative was informed by deep trends analysis and subject-matter-expert interviews. CSIS's Dracopoulos iDeas Lab brought to life the scenarios in four engaging videos designed to test policymakers' preconceived notions about the defense and security challenges facing the United States and its allies in the second half of this decade. This research was sponsored by the Defense Threat Reduction Agency's Strategic Trends Division

Eighty-one percent of U.S. adults say the future of U.S. democracy is under threat, a sentiment shared by most Republicans, Democrats and independents. But when they were asked which party poses the bigger risk, it was a statistical tie between people who said the Democratic Party (42 percent) and the Republican Party (41 percent). An additional 8 percent of Americans blame both parties for playing a role. "We have one point of bipartisan agreement that the ship is sinking," said Edward Foley, who directs the election law program at Ohio State University. "But the problem is that each side blames the other for the ship sinking."
