Fifth National Climate Assessment (NCA5)

PNNL Contributions

 

Climate Impacts on National Security

PNNL scientists have organized an AGU scientific session on the impacts of climate change on national security. What are the risks of long-dormant microbes in thawing permafrost? How will crop production change as temperatures rise, and who will be hungry? If shading the planet through geo-engineering becomes feasible, who will be the winners and who might be the losers?

There are two events Tuesday, Dec. 12. The scientific session will be 10:20 to 11:50 a.m. in 2006 – West (Level 2 West, MC). There’s also a town hall, pulled together by PNNL and NSF officials and others, from 6:30 to 7:30 p.m. that same day in 2007 – West (Level 2 West, MC).

Speakers include:

  1. Jill Brandenberger, the leader of PNNL’s efforts in climate and national security and an organizer of a recent workshop on pathogens and permafrost. Jill works closely with officials at the Department of Defense and other organizations and has a broad perspective on “climate and national security,” from the risks of thawing microbes to the effects of increased heat on soldiers, to the impact of decarbonization and powerful hurricanes on defense bases. Jill is an organizer of the town hall.
  2. Brian O’Neill, a member of the National Academies’ Climate Security Roundtable and a convening lead author of the IPCC’s 6th assessment report. Brian notes that many factors unrelated directly to climate, such as poverty, income, and education, will influence how climate change affects us. In this comment in Nature Climate Change earlier this year, he noted that the assumption that the future will be worse than the present due to climate change may be incorrect. Brian is the lead convener of the scientific session.
  3. Ben Kravitz of Indiana University (with a joint appointment at PNNL), who will speak about the prospects of geoengineering, particularly solar geoengineering, on national security and future climate.
  4. Stephanie Waldhoff will be speaking about food security and vulnerability as the climate changes. She notes that climate is not the only variable to consider when it comes to food – other factors like future income, education and land use changes have a big effect. She is finding that in some areas of the world, food availability is likely to improve, while in other areas, large segments of the population may struggle.

GC11K-0958 Compound Energy Droughts in the Western United States Under Decarbonization

Cameron Bracken hero image

Session: 8:30 a.m. – 12:50 p.m. PST, Location: Poster Hall A-C - South

PNNL Presenter: Cameron Bracken 

Summary: Decarbonization of the grid by 2050 will require a substantial buildout of wind and solar generation in the Unites States. Increased reliance on these renewables brings with it increased risk of weather driven shortages, known as energy droughts. READ MORE.

B11C-05 Alternating Salt and Freshwater Floods of Upland Coastal Soils Damage Soil Structure Changing its Hydraulic Properties

Session: 9:10 – 9:20 a.m. PST, Location: 3007 - West

PNNL Presenter: Kenton Rod

Summary: Coastal soils are increasingly impacted by hydrologic intensification in the form of rising ocean waters and floods from storm surges and precipitation. This generates shifts in pore water chemistry from freshwater to saltwater in addition to changes in redox state. READ MORE.

GC21L-1092 Marine Renewable Energy Resource Characterization and Assessment for Powering the Blue Economy

Session: 8:30 a.m. – 12:50 p.m. PST, Location: Poster Hall A-C - South

PNNL Presenter: Zhaoqing Yang

Summary: Marine renewable energy, which includes renewable energy harvested from ocean waves, tidal streams, ocean currents, and salinity and thermal gradients, can contribute significantly to the nation’s renewable energy portfolio to transition to a net-zero carbon, resilient, and secure energy future. READ MORE.

SY21C-0836 Building Energy Codes: Strategies for Resilience

Session: 8:30 a.m. – 12:50 p.m. PST, Location: Poster Hall A-C - South

PNNL Presenter: Meredydd Evans

Summary: Building energy codes have traditionally played a major role in optimizing energy efficiency in buildings. With the growth of extreme weather paired with long-duration power outages, regulators are increasingly considering if building energy codes could support climate resilience. READ MORE.

GC22B-06 Analyzing the Distributional Impacts of Global Change on Food Access and Availability in a Multi-Sector Dynamics, Human-Earth System Model

Session: 11:12 – 11:22 a.m. PST, Location: 2006 - West

PNNL Presenter: Stephanie Waldhoff

Summary: Changes in both human and physical systems will impact global food access and availability. These impacts will occur unevenly, both across and within countries. Understanding the implications of changes in the climate system, trade patterns, and economic and demographic characteristics on global and local food systems is key to evaluating human well-being. READ MORE.

GC23D-01 Emulators of Climate Model Output, Integrated Modeling, and Scenarios Accounting for Climate Impacts

Session: 11:12 – 11:22 a.m. PST, Location: 2006 - West

PNNL Presenter: Claudia Tebaldi

Summary: Changes in both human and physical systems will impact global food access and availability. These impacts will occur unevenly, both across and within countries.

GC33D-1200 PNNL's Grid Operations, Decarbonization, Environmental and Energy Equity Platform (GODEEEP): Advances in Climate-to-Grid Integration in Support of Energy Transitions

Session: 2:10 – 5:30 p.m. PST, Location: Poster Hall A-C - South

PNNL Presenter: Nathalie Voisin

Summary: The consequences of climate change are expected to dramatically change the way we plan our electricity infrastructure, but utilities do not have accessible, consistent, holistic power-system relevant climate datasets that align with the actionable needs of power system planners. We present a novel end-to-end modeling toolchain and analytical capabilities that link climate science to power grid long term planning, including implications for equity research. READ MORE.

A34B-09 Toward Credible Predictions of Aerosol-Cloud Interactions in Earth System Models

Session: 5:20 – 5:30 p.m. PST, Location: 3004 - West

PNNL Presenter: Po-Lun Ma

Summary: The role of aerosol-cloud interactions in the Earth system is a major source of uncertainty in projections of Earth’s future climate and in interpreting how the climate has evolved in the past. READ MORE.

SY42A-04 Exploring Socioeconomic and Natural Resource Constraints on Electricity System Capacity Expansion Under Decarbonization in the United States

Session: 10:50 – 11:00 a.m. PST, Location: 2018 - West

PNNL Presenter: Kendall Mongird 

Summary: Transition to net-zero economies and associated expansion and decarbonization of the electric grid necessitates careful consideration of the impacts on the communities and environment where the new power capacity is located. Modeling efforts that incorporate these impacts can strengthen our understanding of complex trade-offs and opportunities and provide multisectoral insight towards decarbonization planning. READ MORE.

A431-01 Modeling Extreme Events and their Future Changes (Invited)

Session: 2:10 – 2:20 p.m. PST, Location: 3014 - West

PNNL Presenter: L. Ruby Leung

Summary: Some of the most consequential outcomes of global warming for societies and ecosystems are changes in extreme events. Using a hierarchy of different modeling approaches, we investigate how mesoscale convective systems, atmospheric rivers, and hurricanes may respond to global warming and connect future storm changes to changes in the storm environments.

H43F-2146 How Might Historical Record Droughts in Texas Evolve and Impact Water Resources in a Warming Future?

Session: 2:10 p.m. – 6:30 p.m. PST, Location: Poster Hall A-C - South

PNNL Presenter: Lili Yao

Summary: The Colorado River Basin in Texas underwent a prolonged dry spell from 2008 to 2015, with record meteorological drought in 2011 coinciding with record summer heatwaves, producing severe impacts to agriculture, surface water resources, and the environment. Climate warming is projected to intensify extreme drought and compound dry-hot conditions, underscoring the need for water resource management strategies to consider these risks. READ MORE.

NH43A-01 AI-Ready Benchmark Data Inventory of US Wildfires, Heatwaves, and Droughts
