Last month, a group of 175 researchers, including eight from the 黑料老司机, co-authored published in Earth鈥檚 Future and the Bulletin of the American Meteorological Society.

The paper provides a roadmap for future climate assessments in the U.S. by synthesizing the science and identifying research priorities based on existing gaps. 鈥淯.S. Climate Collection: Informing Assessment of Risks and Solutions鈥� is the first article to appear in a launched by the American Geophysical Union and the American Meteorological Society.

Many of the scientists who co-authored this commentary were invited to contribute to the sixth National Climate Assessment (NCA), slated for early 2028, but were then dismissed in April 2025 after the Trump Administration for the assessment. The fifth NCA was published in 2023.聽

The federal government is legally required to produce a National Climate Assessment chronicling climate change every four years per the . These assessments track new and evolving risks related to climate change, as well as options for mitigation and adaptation. The national scope is key to ensuring that funding and policies represent a broad range of experiences and concerns. 

鈥淚nternational assessments are valuable, but they are not always tailored to the specific regions and issues that are important in the United States. National assessments fill that gap,鈥� said , Washington state climatologist and a research scientist in the UW Climate Impacts Group.

The special collection is not intended to replace the NCA but rather compile research for other scientists, policymakers and members of the public to aid in decision making. The commentary kicks off the collection by identifying where research has advanced, and how risks have changed, in the years since the last assessment. 

鈥淥ur understanding of climate change and its impacts continues to evolve,鈥� said , professor of global health, of environmental and occupational health sciences, and of emergency medicine in the UW School of Medicine. 鈥淐onducting regular climate assessments allows us to systematically evaluate that new evidence, incorporate it into our understanding of current circumstances, present it to stakeholders, and apply it to near-term decisions in our respective sectors.鈥� 

UW News asked each of the UW contributors to elaborate on their role in authoring the commentary and how it connects to their research.

, research scientist, UW Cooperative Institute for Climate, Ocean, and Ecosystem Studies: 鈥淚鈥檓 an oceanographer with intimate experience in federal research funding mechanisms and with a broad familiarity with ocean warming and CO2 uptake with associated acidification and feedback on marine ecosystems and fisheries. Initially I was appointed to coordinate among federal agencies, academics and policymakers, but that changed dramatically when the Trump administration eliminated NCA6. In the scramble I became more of an author, and an editor of the Ocean section. 

鈥淪ome of my research at the UW involves ocean model development in collaboration with NOAA. It was a natural fit to contribute to the discussions on 鈥楽imulations of ocean conditions鈥� and on 鈥業nnovations in ocean observation and data science.鈥欌��


Marina Alberti, UW professor of urban and environmental planning

, professor of urban and environmental planning 鈥淚 led the urban team and the section on urban regions. Urban regions are central to climate assessments. They concentrate populations and human activities, contribute substantially to climate change, and shape how impacts propagate across neighborhoods, metropolitan systems, national supply chains, and global markets. They are also critical places to examine where mitigation and adaptation reinforce one another, where they create trade-offs, and how benefits, costs, and risks are distributed across communities. 

鈥淥ur section argues that future assessments must represent cities as complex dynamic systems. We call for comparative, long-term evaluation of urban mitigation and adaptation strategies. For nature-based solutions, that means testing performance under future climate conditions and assessing multiple functions, life-cycle costs, social and ecological outcomes, and trade-offs rather than simply measuring short-term, project-level benefits.鈥�

Hess: 鈥�The takeaways from the health section, which I helped draft, are that we need more information on health impacts from extreme weather and compound events, as well as information on the costs of these impacts. We also need more strategies for advancing adaptation in public health and health care systems; we need health care interventions to protect patients at particular risk; we need more information on nature-based solutions; and we need more information to help convey the health benefits of a clean energy transition. 

鈥淭he recommendations related to interventions and adaptation in the health sector are particularly relevant to my work at the UW, which is focused on climate change health impacts and opportunities for increasing resilience of the public health and health care systems.

The evidence is robust that the economic value of the health benefits from reducing greenhouse gas emissions would be of the same order of magnitude 鈥� if not larger 鈥� than the costs of reducing emissions. In other words, reducing greenhouse gas emissions would benefit Americans by decreasing hospitalizations and deaths.鈥�

Report describes the barriers Pacific Northwest coastal Tribes face in adapting to climate change /news/2024/08/12/report-describes-the-barriers-pacific-northwest-coastal-tribes-face-in-adapting-to-climate-change/ Mon, 12 Aug 2024 20:23:11 +0000 /news/?p=85991 Among the many effects of human-driven climate change is rising seas. Warmer water takes up more space, and melting or receding polar ice sheets add water to the oceans. Meanwhile, a warmer atmosphere also leads to more destructive coastal storms. Communities worldwide are adapting by moving away from vulnerable shores.

Many Tribes in Washington and Oregon call coastal areas home, meaning they are especially affected by climate change. They also face changes in wildfire risk and in changes to fisheries that are economically and culturally important.

A led by the 黑料老司机鈥檚 Climate Impacts Group, the Affiliated Tribes of Northwest Indians, and Washington Sea Grant compiles the experiences of Washington and Oregon coastal Tribes as they prepare for climate change. The report aims to build on successes and identify common barriers to progress.

鈥淓very year the climate crisis continues to elevate and accelerate. The lack of a coordinated federal response is what causes Northwest coastal Tribes 鈥� and other coastal communities 鈥� to suffer from hazards which are imminently impacting life, property, Tribal rights and resources,鈥� said project co-lead of the . 鈥淲ith direct quotes from Tribal citizens and staff with lived personal and professional experiences, [this report] describes the immediate urgency of the federal government to take coordinated climate action.鈥�

鈥溾�� is freely available online

Related: 鈥溾�� – The Associated Press

Results will be shared with Northwest coastal Tribes and other governmental and nongovernmental entities.

鈥淭he report is based on listening sessions with Northwest coastal Tribes, and summarizes the barriers and unmet needs they face in their efforts to prepare for climate change,鈥� said project co-lead Meade Krosby, who is director of the UW-based and senior scientist at the UW . This report was funded by the National Oceanic and Atmospheric Administration through the .

The project team held six Tribal listening sessions, each 2.5 hours long, in varying formats. Three listening sessions took place during Affiliated Tribes of Northwest Indians conferences already attended by many Northwest coastal Tribal members.聽Two sessions were held virtually, and one was hosted by an individual Tribal Nation. Participants in each session met in small groups and shared information with each other and with a moderator.

All participants had the choice of making their comments public or not, and of contributing anonymously or under their name. Researchers later coded all the contributions and summarized the overall findings. Contributions represented 13 Tribal nations, roughly half of the federally recognized Tribes within the study鈥檚 coastal regions. The overall findings include:

  • Despite being national leaders in climate adaptation, Northwest coastal Tribes face significant needs in realizing their adaptation goals
  • Key barriers and unmet needs centered in five areas: funding, staffing, technical expertise, partnerships and communications
  • Successful efforts noted strengths in many of these same areas, such as securing external funding, the dedication of Tribal staff, and building robust partnerships

Participants described specific situations and frustrations, including the piecemeal nature of federal funding; challenges recruiting and retaining key staff; potential partners鈥� lack of familiarity with Tribal processes and priorities; and establishing stable support for long-term initiatives.

Participants鈥� quotes included:

鈥淚f you just looked at the total amount of Tribal land, you鈥檇 say: 鈥榃ell, there鈥檚 lots of places that the Tribe can move,鈥� but if you take away all the places that are sacred or culturally significant, or habitat for important species, or landslide hazard, or some other hazard, the options are diminished. We must also be careful not to move away from one hazard into another. How bad would it be if we move away from the shoreline, and we put ourselves in harm鈥檚 way for fire?鈥�

鈥� Robert Knapp, environmental planning manager and climate resilience lead, Jamestown S鈥橩lallam Tribe

鈥淪ome of the challenges that we face on the coast are due to the magnitude of some of the projects that we need to undertake. For example, we are in the midst of relocating our two main Quinault villages on the Washington coast. That鈥檚 a multimillion-dollar, multi-agency effort 鈥� It鈥檚 very difficult to integrate our plans and priorities for village relocation with those of the agencies and constrains on available funding.鈥�

鈥� Gary Morishima, natural resources technical advisor, Quinault Indian Nation

鈥淭o build capacity we need funding sources that are long-term, that we can say to Tribal leadership: 鈥榃e know we鈥檙e going to have funding for five or six years, so we want to hire this person who鈥檚 an engineer, who鈥檚 a project manager, who can take on these projects, talk to other [external] engineers, and who can make these projects happen.鈥欌��

鈥� Rochelle Blankenship, Tribal council member and executive director, Jamestown S鈥橩lallam Tribe

The report concludes: 鈥淲hile these findings do not fully represent the depth and breadth of [the challenges faced by Northwest coastal Tribes] and what is required to address them, we hope they will help build awareness among funders, policymakers, climate service providers and others to mobilize necessary action in support of the climate adaptation efforts of Northwest coastal Tribes.鈥�

In related upcoming work, the Northwest Climate Resilience Collaborative鈥檚 Tribal Coastal Resilience effort at the UW was as part of a to support coastal readiness in Washington state.

The grant will support hiring a full-time climate adaptation specialist to provide technical assistance to Northwest coastal Tribes, Krosby said. That person will also coordinate a small grants program that will distribute most of the funds to Tribes to support their adaptation efforts. The grants program was designed to respond to Tribal priorities without imposing barriers that often make funds difficult to apply for and administer. Awards will be made starting in 2025.

鈥淲e’re really excited that this is happening at the same time our report is coming out,鈥� Krosby said. 鈥淪o it’s not just describing the problem. It’s also: Here, let鈥檚 bring some resources to bear based on what we learned.鈥�

Assessing riverside corridors 鈥� the ‘escape routes’ for animals under climate change 鈥� in the Northwest /news/2019/02/12/assessing-riverside-corridors-the-escape-routes-for-animals-under-climate-change-in-the-northwest/ Tue, 12 Feb 2019 17:46:14 +0000 /news/?p=60882

Under climate change, plants and animals will shift their habitats to track the conditions they are adapted for. As they do, the lands surrounding rivers and streams offer natural migration routes that will take on a new importance as temperatures rise.

An open-access led by the 黑料老司机 pinpoints which riverside routes in Washington, Oregon, Idaho and western Montana will be the most important for animals trying to navigate a changing climate. The study was published this fall in PLOS One.

“This corridor network is already there, and it’s already important for animal movement,” said lead author , a scientist in the UW’s Climate Impacts Group. “Under climate change these will become ‘superhighways’ for animals that are seeking new places to live. We’ve identified ones that could be priorities for conservation and restoration.”

Riparian areas 鈥� areas of habitat along the banks of rivers and streams 鈥� are known to be used by bears, coyotes, wolves, deer, mountain lions and other large mammals. But these regions could also benefit smaller mammals, like beavers and marmots, and even insects, birds and other species looking for cooler, moister terrain as conditions become less habitable.

“” in ConservationCorridor.org

at UW Climate Impacts Group

“We aren’t the first to realize that riparian areas are likely to be really important for animals seeking refuge from warmer or drier conditions, or for connecting fragmented habitats under climate change,” Krosby said. “But we hadn’t seen anybody identify which riparian areas would be particularly valuable in the future.”

The authors developed a ranking system for riparian areas and applied it to the Northwest, creating a general technique that could be applied elsewhere. They rated the land surrounding rivers and streams for various features that would help animals on the move: width; amount of shade; tree cover; connection across temperature gradients; and general condition of the landscape.

Results show that the highest-quality routes in the Northwest are mostly in the mountains, which have shaded, well-protected riparian corridors that connect warmer to cooler habitats.

The authors then looked at which areas should be priorities for restoration 鈥� places that are not currently protected, or that offer the only natural pathway linking warmer and cooler landscapes. Here the routes through the Columbia Plateau, covering Eastern Washington, central Oregon and western Idaho, popped out as particularly important.

“If you look at an aerial photograph of an agricultural or urban landscape you’ll see these green corridors that follow streams and rivers,” Krosby said. “Humans use the flat areas of the landscape: we live there, we farm there, we use it for all kinds of things. So the riparian areas in these landscapes may not be in the best shape, but in some ways they’re the most valuable, because they’re the only natural habitat left.”

The authors don’t identify individual waterways as priorities for riparian conservation. Instead they leave it to regional managers to single out individual areas and choose methods 鈥� whether it be working with landowners to keep areas in a natural state, planting native vegetation, removing invasive species along streams, creating easements in property deeds, or other methods 鈥� to ensure that riverside land remains friendly to wildlife movement.

“Riparian areas offer a huge bang-for-buck as conservation opportunities in the effort to reconnect our fragmented habitats,” Krosby said. “The nice thing about riparian conservation is it’s a two-fer: The same vegetation that provides cover for terrestrial species moving through riparian zones can, for example, help shade streams to cool water temperatures for aquatic species.”

The study is part of a growing trend in wildlife conservation. This winter, the state of Washington anticipates opening a over Interstate 90 at Snoqualmie Pass, which will allow animals to safely cross the freeway. That infrastructure in combination with other measures could help animal populations be more resilient to climate change.

“The idea is to have a whole network: You want to make sure that your landscape is permeable to wildlife movement,” Krosby said. “That’s important now, and it’s especially important under climate change, because moving to track shifting habitats is the primary way that species deal with a changing climate.”

The research was funded by the Washington Department of Fish & Wildlife, the North Pacific Landscape Conservation Cooperative, the U.S. Fish and Wildlife Service and the Wilburforce Foundation.

Co-authors are David Theobald at Conservation Science Partners, Robert Norheim at the UW’s Climate Impacts Group, and the late Brad McRae at The Nature Conservancy.

New resources support tribes in preparing for climate change /news/2018/11/14/new-resources-support-tribes-in-preparing-for-climate-change/ Wed, 14 Nov 2018 17:22:06 +0000 /news/?p=59814

Which Pacific Northwest streams will warm the most in the next 50 years, and where would restoration work make a difference for salmon? Where will wildfires and pests be most aggressive in forests as the Earth warms, and how can better management help?

As the natural world responds to climate change, American Indian tribes across the country are grappling with how to plan for a future that balances inevitable change with protecting the resources vital to their cultural traditions.

The 黑料老司机 and regional tribal partners have developed a that may be useful to tribes at any stage in the process of evaluating their vulnerability to climate change. The project is a partnership among tribes, tribal associations, universities and the federal government.

“This work really is to support tribes鈥� leadership in climate adaptation, and the goal is to make it easier for every tribe that wants to complete the process,” said , a research scientist at Climate Impacts Group and the project lead. “This is a way to support the tribes that are leading the way, but also to make sure those that are having a harder time getting started have the resources to begin.”

Many tribes are deeply tied to the natural environment for culturally significant practices and traditions, health and livelihoods. Most tribes have reservations and treaty rights that are connected to specific places and resources, making it a challenge to go elsewhere in response to future changes in climate.

This new suite of resources is intended to support tribes in all phases of assessing the possible impacts of climate change 鈥� in other words, how a warming world might affect the things each tribe cares about most. The tools are tailored geographically to each of the 84 tribes in the Pacific Northwest and Great Basin regions of the western U.S., with the possibility to expand across the country.

The , mainly online, include a climate tool that provides interactive summaries of projected climate change on annual precipitation, stream temperatures, growing season, fire danger and other variables. It also provides links to resources such as guidebooks and sample climate assessments, and a technical support line for tribal staff and members to call with any questions. Both Western science and indigenous approaches that draw on traditional ecological knowledge are featured in the resource toolkit.

While other tools exist to help assess vulnerability to climate change, these resources present information about future predictions in a user-friendly format that focuses on areas of geographic importance to various tribes. Project leaders spent considerable time testing the tools with tribal staff and community members to make the resources more intuitive and responsive to their needs, Krosby said.

“This is a way to get cutting-edge climate information directly into the hands of tribes,” she said. “Overwhelmingly, the response among tribes has been positive.”

The project began about two years ago after an initial assessment led by Don Sampson, climate change project manager with the , in partnership with the Northwest Climate Adaptation Science Center, found that a number of tribes didn’t have the resources or staff to plan for climate change.

In response, the Northwest Climate Adaptation Science Center and Great Basin Landscape Conservation Cooperative funded the UW Climate Impacts Group 鈥� under the guidance of a tribal advisory group 鈥� to develop climate change resources that could help fill gaps for those tribes needing additional support.

The Climate Impacts Group contacted all 84 tribes in the Northwest and Great Basin regions, asking what climate impacts they were most concerned about and which geographic areas are important to them. As responses came in, it was clear each tribe had specific factors they were most concerned about, including how stream temperatures, snowpack and habitat might change in the future in their location.

“For some tribes just beginning to look at climate impacts on important resources to their communities, they can analyze quite quickly and begin to narrow their focus to some of the priority resources, whether it be salmon, deer and elk, or migratory birds,” Sampson said. “Our goal is for all of Indian Country to have a tool like this and get all of the tribes in the country able to assess the impacts of climate on their resources.”

“The Affiliated Tribes of Northwest Indians and the tribes of the Pacific Northwest are leading tribal efforts nationwide to address climate change impacts in Indian Country. This project, in collaboration with the 黑料老司机, represents us using our traditional knowledge and the best available scientific analysis,” said Leonard Forsman, president of the Affiliated Tribes of Northwest Indians.

As one example, the Makah Tribe in northwest Washington has started to form a plan to adapt to climate change, drawing on these resources as well as community surveys, elder interviews and staff input to consider aspects such as natural resource management, infrastructure, health, cultural activities and carbon mitigation. They have found the new tools to be particularly useful in analyzing potential climate impacts on their specific area, said Mike Chang, climate adaptation specialist at the Makah Tribe.

“The downscaled climate models are able to provide information at locally relevant scales. This is super helpful because many regional climate models can’t provide hyper-local climate projections, which is crucial when making planning and adaptation decisions,” Chang said.

The new climate resources are mainly online and include a climate tool, links to resources and a technical support line for tribal staff and members. Photo: 黑料老司机

Like the Makah Tribe, planning for climate change is underway for many tribes across the country, said Rachael Novak, Tribal Resilience Program coordinator with the Bureau of Indian Affairs. About 10 percent of federally recognized tribes have a plan drafted, but the remaining tribes 鈥� still over 500 鈥� are at various points in the process, from implementing adaptation plans to assessing possible impacts to not having begun. Time and resources are usually the biggest barriers to creating a plan, she said.

“There’s so much diversity across Indian Country and Alaska Native Villages in terms of staffing and resources,” Novak said. “It’s important to have tools to be able to connect and meet people where they are in planning for climate change.”

Project leaders will continue to offer trainings on using the online assessment resources; Krosby will hold a Nov. 15 to go over the climate tool and how tribes can begin using it.

The project was funded by the Northwest Climate Adaptation Science Center and the Great Basin Landscape Conservation Cooperative.

Risk of interbreeding due to climate change lower than expected /news/2015/07/06/risk-of-interbreeding-due-to-climate-change-lower-than-expected/ Mon, 06 Jul 2015 15:12:34 +0000 /news/?p=37758 One of the questions raised by climate change has been whether it could cause more species of animals to interbreed. Two species of flying squirrel have already produced because of climate change, and there have been reports of a hybrid polar bear and grizzly bear cub (known as a grolar bear, or a ).

“Climate change is causing species’ ranges to shift, and that could bring a lot of closely related species into contact,” said , a research scientist in the 黑料老司机’s .

She is the lead author of a published July 6 in that tallies the potential number of such pairings. Looking across North and South America, it finds that only about 6 percent of closely related species whose ranges do not currently overlap are likely to come into contact by the end of this century.

“People have been concerned that climate change would be bringing all these species into contact, and that this could unleash a wave of interbreeding,” Krosby said. “What we found is, not so much.”

A 2010 in the journal Nature suggested that northern species may begin to interbreed and create a so-called “Arctic melting pot,” and even prompted one of what those new offspring would look like.

The idea also worried land managers looking at how to prepare for climate change. At a workshop, land managers told Krosby they worked with very closely related species separated by small distances. What if managers linked the two areas with a wildlife corridor, and as the climate changed the species started to mix?

This study is an attempt to see how much that should be a concern. It looked at 9,577 pairs of closely related species of birds, mammals and amphibians in North and South America. For the 4,796 pairs whose ranges currently do not overlap, computer models show that only 6.4 percent of them will come into contact due to climate change by the year 2100.

The most overlap among species occurred in the tropics, and among birds, likely because more species live in the tropics and birds cover wider ranges, Krosby said.

While the study suggests that climate change is unlikely to result in widespread interbreeding, wildlife biologists still need to consider their particular region and animals of interest to best protect specific populations.

“Managers still need to look case-by-case at species at a local scale, but at a global scale, the big picture is that it’s probably not going to be a huge problem,” Krosby said.

The study likely overestimates how many species could be at risk of interbreeding because it assumes that all species will be able to access new habitats that become available due to climate change. In fact, natural barriers prevent animals from reaching all potential new habitats, and humans have created new barriers such as highways, farms, and cities that can block migrations to more hospitable places.

“The number one strategy for helping biodiversity respond to climate change is to increase connectivity, to link up habitats that have been fragmented by human activity, so species can move, and track climate as it shifts to stay comfortable,” Krosby said.

“If people are worried that wildlife corridors and other ways to increase connectivity could bring these species into contact, we’re saying: That’s probably not going to happen, and allowing species to move is far more important.”

Krosby did her doctoral work looking at how historic climate changes affected species in the past, including how the end of the last ice age led to interbreeding among . Now she focuses on contemporary climate change, to see how species are responding and how land managers can best protect biodiversity under faster, human-driven changes to Earth’s climate.
