Global Change and Extreme Hydrology - Testing Conventional Wisdom - National Research Council

Climate theory dictates that core elements of the climate system, including precipitation, evapotranspiration, and reservoirs of atmospheric and soil moisture, should change as the climate warms, both in their means and extremes. A major challenge that faces the climate and hydrologic science communities is understanding the nature of these ongoing changes in climate and hydrology and the apparent anomalies that exist in reconciling their extreme manifestations. The National Research Council (NRC)..

Attribution of Extreme Weather Events in the Context of Climate Change - National Academies Of Sciences Engineeri

\As climate has warmed over recent years, a new pattern of more frequent and more intense weather events has unfolded across the globe. Climate models simulate such changes in extreme events, and some of the reasons for the changes are well understood. Warming increases the likelihood of extremely hot days and nights, favors increased atmospheric moisture that may result in more frequent heavy rainfall and snowfall, and leads to evaporation that can exacerbate droughts. Even with evidence of these..

Frontiers in Data Analytics and Monitoring Tools for Extreme Materials: Proceedings of a Workshop - National Academies Of Sciences Engineeri

One of the major challenges in materials science today is developing materials that can survive and function in extreme environments, such as the high-radiation environments found in a fission or fusion reactor or the ultra-high temperature experienced by a hypervelocity vessel or a spacecraft traveling through Earths atmosphere on its return to the planets surface. What is needed to discover such materials was the topic of a 2-day workshop held at the National Academies of Sciences, Engineering,..

Severe Space Weather Events—Understanding Societal and Economic Impacts - A Workshop Report: Extended Summary - National Research Council

The adverse effects of extreme space weather on modern technology--power grid outages, high-frequency communication blackouts, spacecraft anomalies--are well known and well documented, and the physical processes underlying space weather are also generally well understood. Less well documented and understood, however, are the potential economic and societal impacts of the disruption of critical technological systems by severe space weather. This volume, an extended four-color summary of the book,..

An Assessment of Native Seed Needs and the Capacity for Their Supply: Final Report - National Academies Of Sciences Engineeri

\Extreme weather and wildfires, intensified by climate change, are damaging the native plant communities of landscapes across the United States. Native plant communities are foundational to thriving ecosystems, delivering goods and services that regulate the environment and support life, provide food and shelter for a wide range of native animals, and embody a wealth of genetic information with many beneficial applications. Restoring impaired ecosystems requires a supply of diverse native plant..

Modeling the Health Risks of Climate Change: Workshop Summary - National Research Council

Climate change poses risks to human health and well-being through shifting weather patterns, increases in frequency and intensity of heat waves and other extreme weather events, rising sea levels, ocean acidification, and other environmental effects. Those risks occur against a backdrop of changing socioeconomic conditions, medical technology, population demographics, environmental conditions, and other factors that are important in determining health. Models of health risks that reflect how health..

Hurricane Elena, Gulf Coast: August 29 - September 2, 1985 - National Research Council

Hurricane Elena, following an erratic and difficult-to-forecast course along an unusually large section of the Gulf Coast, posed special problems from New Orleans, Louisiana, to Sarasota, Florida, well before it came ashore on September 2, 1985. Considerable wind damage occurred in this area to structures that were ostensibly designed to resist such extreme wind conditions. Because similar design conditions and building control procedures exist along other U.S. hurricane-prone coasts, the conclusions..

The State of Resilience: A Leadership Forum and Community Workshop: Proceedings of a Workshop - National Academies Of Sciences Engineeri

Over the past decade, resilience has gained significant traction across the nation and innovative programs are showing exciting progress in building resilient communities. For communities to be prepared for future extreme weather and climate events, as well as the chronic daily stressors, the momentum of implementing and taking action to build community resilience should continue to be fostered and expanded. Building on its many efforts dedicated to increasing and enhancing resilience, the Resilient..

Exploration of Antarctic Subglacial Aquatic Environments - Environmental and Scientific Stewardship - National Research Council

Antarctica is renowned for its extreme cold; yet surprisingly, radar measurements have revealed a vast network of lakes, rivers, and streams several kilometers beneath the Antarctic ice sheet. Sealed from Earth's atmosphere for millions of years, they may provide vital information about microbial evolution, the past climate of the Antarctic, and the formation of ice sheets, among other things. The next stage of exploration requires direct sampling of these aquatic systems. However, if sampling is..

A Strategic Vision for NSF Investments in Antarctic and Southern Ocean Research - Engineering National Academies of Sciences

Antarctic and Southern Ocean scientific research has produced a wide array of important and exciting scientific advances. Spanning oceanography to tectonics, microbiology to astrophysics, the extreme Antarctic environment provides unique opportunities to expand our knowledge about how our planet works and even the very origins of the universe. Research on the Southern Ocean and the Antarctic ice sheets is becoming increasingly urgent not only for understanding the future of the region but also its..

Progress and Priorities in Ocean Drilling: In Search of Earth's Past and Future

Research supported by scientific ocean drilling has fundamentally transformed our understanding of the planet with key contributions to the discovery and theory of plate tectonics; the formation and destruction of ocean crust; the reconstruction of extreme greenhouse and icehouse climates; the identification of major extinctions; and the discovery of a diverse community of microbes living deep ocean seafloor. With the retirement in 2024 of the JOIDES Resolution-- the U.S. dedicated drilling vessel..

Views of the U.S. National Academy of Sciences and National Academy of Engineering on Agenda Items at Issue at the World Radiocommunication Conference

The passive, receive-only Radio Astronomy Service (RAS) and the Earth Exploration-Satellite Service (EESS) provide otherwise impossible scientific observations of the Universe and Earth through the use of advanced receiver technology with extreme sensitivity and the employment of complex noise reduction algorithms. Even with such technology, RAS and EESS are quite adversely affected by what most active services would consider low noise levels. To ensure their ability to use the radio spectrum for..

Future Science Opportunities in Antarctica and the Southern Ocean - Committee on Future Science Opportunities in Antarctica and the Southern Ocean

\Antarctica and the surrounding Southern Ocean remains one of the world's last frontiers. Covering nearly 14 million kmp2s (an area approximately 1.4 times the size of the United States), Antarctica is the coldest, driest, highest, and windiest continent on Earth. While it is challenging to live and work in this extreme environment, this region offers many opportunities for scientific research. Ever since the first humans set foot on Antarctica a little more than a century ago, the discoveries made..

Climate Intervention - Reflecting Sunlight to Cool Earth - National Research Council

\The growing problem of changing environmental conditions caused by climate destabilization is well recognized as one of the defining issues of our time. The root problem is greenhouse gas emissions, and the fundamental solution is curbing those emissions. Climate geoengineering has often been considered to be a \last-ditch\ response to climate change, to be used only if climate change damage should produce extreme hardship. Although the likelihood of eventually needing to resort to these efforts..
