The socio-spatial dimensions of disaster risk in mobile home parks: Learning from the 2013 Colorado floods by Andrew Rumbach and Esther Sullivan, University of Colorado Denver

This talk will be available via live webcast. To view the live webcast please go to Adobe Connect and login as a guest.

Mobile home parks are an important source of affordable housing for millions of U.S. households. Mobile home parks are frequently exposed to floods, storms, and other natural hazards, so much that researchers use them as an indicator of vulnerability in the built environment. While numerous studies have documented the physical vulnerability of mobile home parks, disaster researchers have a limited understanding of the socio-spatial dimensions of risk in such communities. In this talk, we examine the unique contribution of mobile home parks to disaster risk through a detailed study of the 2013 Colorado floods. The floods destroyed over 450 mobile homes and permanently displaced thousands of people from their communities. Drawing on data collected through household surveys, semi-structured interviews with recovery officials, and observation of recovery planning meetings, we describe four socio-spatial dimensions of risk in mobile home parks: concentrated vulnerability, divided asset ownership, restrictive or exclusionary planning, and community bias. Our analysis reveals tensions between growth, housing affordability, and community resilience, an important consideration for community planners and disaster management officials. We conclude by describing policy and planning interventions that might mitigate risk and improve recovery outcomes for mobile home park residents and owners.

Andrew RumbachAndrew Rumbach is an Assistant Professor in the Department of Planning and Design at the University of Colorado Denver. His research centers on community risk and resilience to natural hazards and climate change, in the United States and India. He is especially interested in how planning and urban governance shapes the geographies of risk and resilience in cities. His current research projects include a longitudinal study of household and community recovery after the 2013 Colorado floods; an examination of the role of collaborative networks in protecting historic resources from environmental hazards; and a study of small cities and environmental risk in the Darjeeling-Sikkim region of eastern India. Rumbach holds a doctorate and a master’s degree in City and Regional Planning from Cornell University and a bachelor’s in Political Science from Reed College.

 

Esther Sullivan is an urban sociologist and Assistant Professor at the University of Colorado Denver. Her research focuses on poverty, spatial inequality, legal regulation, housing, and the built environment, with a special interest in both forced and voluntary residential mobility. Her research uses both ethnographic methods and geospatial (GIS) analysis. She holds a Ph.D. in Sociology from The University of Texas at Austin. Her current book project Manufactured Insecurity: Mobile Home Park Evictions and Americans' Tenuous Right to Place (August 2018, University of California Press) is a mixed-method look at the mass evictions that result when mobile home parks close. Living full time inside closing mobile home parks across Texas and Florida, the project examines the effects of forced relocation on individuals and communities, as well as the operation of markets that profit off the low-income housing found in mobile home parks.

Was there a climate warming “Hiatus” in the Arctic? by Kang Wang, INSTAAR, University of Colorado Boulder

Abstract:

Historically, in situ measurements have been notoriously sparse over the Arctic. As a consequence, the existing gridded data of surface air temperature (SAT) may have large biases in estimating the warming trend in this region. Using data from an expanded monitoring network with 31 stations in the Alaskan Arctic, we demonstrate that the SAT has increased by 2.19°C in this region, or at a rate of 0.23°C/decade during 1921–2015. Meanwhile, we found that the SAT warmed at 0.71°C/decade over 1998–2015, which is 2 to 3 times faster than the rate established from the gridded data sets. Focusing on the “hiatus” period 1998–2012 as identified by the Intergovernmental Panel on Climate Change (IPCC) report, the SAT has increased at 0.45°C/decade, which captures more than 90% of the regional trend for 1951–2012. We suggest that sparse in situ measurements are responsible for underestimation of the SAT change in the gridded data sets. It is likely that enhanced climate warming may also have happened in the other regions of the Arctic since the late 1990s but left undetected because of incomplete observational coverage.

Title: (Danger from the sea – Sea-level rise in a changing climate)

Abstract: The rise in ocean levels is among the most dangerous of the many secondary effects of near-future climate warming. On a global scale, sea level is currently rising at an average rate of about 3.5 mm/yr; this rate is nearly 50% higher than rates during the first half of the past century. Sea-level rise has been driven by a nearly 1oC rise in average Earth surface temperature since the early 1900s and, more specifically, has resulted from the loss of alpine glacier ice cover and thermal expansion of ocean waters. A further minimum 1oC rise in average global temperature is ‘locked in’, perhaps before the middle of this century. Continuing warming will ensure that the sea surface will continue to rise, likely reaching an average level nearly 1 m higher than today by the end of the century. This rate of sea-level rise is without precedent in the Holocene and matches some of the highest rates of the Pleistocene Epoch.

Recently, a group of respected climate scientists argued that IPCC has underestimated the amount of sea-level rise by the end of this century due to as yet poorly understood contributions of water from Greenland and Antarctica. Uncertainties in future rates and magnitudes of sea-level rise stem largely from two sources – future anthropogenic carbon emissions and poor knowledge of how rapidly Earth’s cryosphere will equilibrate to the warmer climate we face. Projected costs of protecting existing low-lying coastal infrastructure from higher seas could amount to hundreds of trillions of dollars. However, even with a massive effort, traditional engineering measures, mainly sea dykes, will be effective only for 1-2 m of sea-level rise. Displacement of hundreds of millions of people from low-lying coastal areas, with attendant social disruption and strife, will accompany sea-level rise more than 2 m.

"The Unraveling Arctic: Science, Communications and Policy" by Rafe Pomerance, Chairman Arctic 21.

Abstract:

Greenland and Arctic glaciers are shrinking. Sea ice and spring snow cover are in decline.  Permafrost is thawing. These trends amount to the unraveling of the Arctic.  In response, Arctic 21 was established as a network of non governmental organizations, scientists and research institutions  with two goals: #1 to communicate the ongoing unraveling; #2 to establish a policy framework to increase the likelihood of an appropriate response by governments both in the Arctic and globally.   Crucial to this effort was to convince the Obama State Department to make climate change in the Arctic a focus of the US Chairmanship of the Arctic Council and to describe the global consequences of climate change the Arctic.  Arctic 21 was then able to pursue a framework for policy by asking the question, “What is the Arctic we have to have to sustain the global climate system?”.  At this point several multilateral governmental institutions will have to face the unraveling, including the Arctic Council,  the Intergovernmental Panel on Climate Change, and the Conference of the Parties of the Paris Agreement.

Ball Aerospace Guest Lecture

Ball Aerospace Guest Lecture

Earth Sciences at Ball Aerospace – Where We’ve Been and Where We’re Going by Dr. Shelley Petroy, Ball Aerospace, Earth Science Mission Development
 
Since the 1950’s, Ball Aerospace has engineered some of the world’s pioneering earth and space science missions. When climatologists need more accurate data and weather forecasters want to predict days in advance, we’re their go-to partner. Flying on our spacecraft, instruments like TEMPO, GMI and CALIPSO gather extremely accurate data on pollution, precipitation and the impacts of clouds and aerosols on Earth’s climate. Today, coupled with breakthrough technologies, shrinking spacecraft size, increased access to space, and the growing commercial data market, Ball is moving into “new space” with a suite of small sensors, spacecraft and enabling technologies that maintain mission performance, but take advantage of these new market drivers to reduce costs and lower risk. Come find out where we’ve been and where we’re going in earth sciences

Lecture from 9:00am to 10:am in the CIRES Auditorium, followed by informal discussion in the ESOC Reading Room from 10:00am to 11:00am.

November 2017 CMC Meeting

November 2017 CMC Meeting

Meeting Minutes

12:10pm - The meeting was called to order.  Minutes taken by Mistia Zuckerman.

Attendance

Mimi Hughes, current chair (PSD), Mistia Zuckerman (NSIDC), Patrick Veres (CSD) Chelsea Thompson (CSD), Alessandro Froundin (CSD, visitor), Carrie Morrill (NCEI), Eric Adamson (SWPC), Eric James (GSD), Lucia Harrop (Admin), Michael Toy (GSD, visitor), Amanda Morton (Outreach/Admin), Kathy Lantz (GMD), Sonja Wolter (GMD), Jonathan Kofler (GMD), Nate Cambell (CIRES), Carrie Wall (NCEI)

Summary of Action Items

  • Mimi will try to create Google invitations for future meetings. 
  • Everyone should read the CIRESness and equities report and see what is still relevant.
  • Each ‘cluster’ will send out an invitation to the next meeting to those they represent.

CIRES Budget & Updates with Waleed

Mimi and Robin met with Waleed. Mimi described the three items they discussed: 
1).  Requested a budget increase so that we could have ~9 meetings a year at Backcountry Pizza (and/or a few ‘tour’ meetings). We now have a larger CMC membership than when the budget was originally created.   2) Asked how CMC leadership should interact with CIRES’ new leadership structure.  They decided that Robin and Mimi will meet with Heather and Christine after every CMC meeting.  3) They discussed whether or not we need a member from SEEC, which we will decide later today. 

Membership Chair

Eric James volunteered to be membership chair.  Chelsea Thompson seconded his nomination. 

  • Motion: To make Eric James membership chair.

The motion was approved unanimously. 

SEEC Membership

 Nate found that 26 people have their home office marked as SEEC (including EarthLab).  Discussion ensued regarding the fact that there are people at ATOC, civil engineering, Envs, and EarthLab in the SEEC building.  Physically, they are very far away from East Campus.  Waleed said that he would support SEEC representation if we decided whether membership is based on location or department.  As part of SEEC, it might make sense to have a representative. We agreed to have the SEEC building represented them on the CMC unless we find out that they are not primarily represented on main campus.

Later on in the meeting Nate found that the SEEC building has 7 CIRES employees once those with offices on other campuses are excluded so we are not going to have a SEEC representative. 

OPA Eligibility

Mimi read the description of OPA Eligibility.  She explained that last year one team was not eligible because it had a post-doc and a graduate student on it.  Discussion ensued regarding whether or not graduate students should be eligible and the distinction between grad students and post-docs, that graduate students get student award opportunities, recognizing longer-term scientists.  Government employees are the ones who are supposed to be getting the money.  . 

  • Motion: To make post-docs eligible for OPA awards. 

The motion was approved unanimously.  

  • Motion:  To allow graduate students to be eligible for an OPA award if they are part of a nominated team. The motion was approved.    

Possible language:  Research associates, research scientists, and post-docs who are CIRES employees are eligible for OPA awards.  

  • We will wordsmith via email and vote on it later. 

CMC Bylaws

Heather and Christine want to review our bylaws.  Mimi mentioned that Robin would like more detail into the bylaws.  There is something that is in the pile of stuff that was in the Google drive.  Nate will talk to Robin to show her the archive.  (OPA is taken care of)

CIRES Bikes

Mistia talked about the two bikes on East Campus.  Discussion ensued.  Mistia will talk to Lucia about storing the bikes during the winter and what to do with the extra one.     

List of items for Heather

Heather wants to open up communication with the CMC. 

Equities and CIRESness report

Mimi requested that everyone please read equities report and CIRESness report and see what is still relevant.  These reports compared CIRES and NOAA employment to gauge morale.  It was a response to the ARPAC.  The CIRES report was more about identity. 

Engagement

Mimi discussed the question from a few months ago, “Are people bringing issues to the CMC?”  Discussion ensued regarding how groups can practically maintain a list of membership.  Lucia said that she was willing to generate a list after every meeting.  Patrick mentioned other methods for pulling names.  Mimi wondered if an email within their division will improve their awareness of the CMC or if we should send out an email with minutes.  It was decided that a link to the minutes would be appropriate.  Action item: Each cluster rep will send out the invitation to the next meeting with a link to last meeting’s minutes.

Discussion ensued about town halls and other ways to get people involved. 
Conclusion: we will do a summer tour (previously called a town hall).  This time, just have a regular meeting. 
Mimi is open to all idea.  CMC coffees: come and meet your CMC reps and have a cup of coffee with them. 

Rendezvous committee

Due to the automation of numerous tasks surrounding the Rendezvous, Nate asked if forming a committee for the 2018 Rendezvous was necessary. The alternative of Nate identifying volunteers for tasks was proposed.  Mimi will check if there is anything in the bylaws that says there must be a committee; if not, Nate will not form a formal committee, but will ask for volunteers as necessary.

Atmospheric Chemistry Program Seminar

Atmospheric Chemistry Program Seminar

Optimization of Surface-Initiated Atom Transfer Radical Polymerization for Application to Small Analyte Detection by Nathan Reed, CU Boulder, ANYL 1st year
"The research project I contributed to as an undergraduate student sought to investigate molecular transport as a means of signal enhancement in small analyte detection. Selective transport of analyte molecules to a nanosensor location will lower the limit of detection compared to analyte collection from free diffusion alone. Polymer brushes can be grown off a detector surface directly and can then be used to bring small molecules closer in proximity to the detector. The small molecules will selectively partition into the polymer-brush surface based on attractions caused by hydrophobic effects, hydrogen bonding, or ionic interactions. To foster such controlled and specific interactions on a device surface, uniform polymer thin films needed to be synthesized and the appropriate materials used for transport of target analytes needed to be understood. Additionally, there was a need for the method to be standardized so that non-polymer scientists and engineers could replicate it with ease. Atom transfer radical polymerization (ATRP) presented a polymerization technique able meet these needs. ATRP is a controlled polymerization technique whose parameters may be tuned to meet specific needs such as functionality and length. In addition, ATRP is an approachable technique to scientists unfamiliar with polymerization techniques once synthetic methods are unified and optimized. My undergraduate research has investigated ATRP reaction conditions applicable to a broad range of polymer types, both in solution and surface-tethered, to develop a unified and optimized synthetic approach."

Global simulation of brown carbon and single scattering albedo calculation using a chemical transport model by Duseong Jo, CU Boulder, Postdoc
"Recent observations suggest that a certain fraction of organic carbon (OC) aerosol effectively absorbs solar radiation, which is also known as brown carbon (BrC) aerosol. Despite much observational evidence of its presence, very few global modeling studies have been conducted because of poor understanding of global BrC emissions. I will present an explicit global simulation of BrC in a global 3-D chemical transport model (GEOS-Chem), including global BrC emission estimates from primary (biomass burning and biofuel) and secondary sources. The BrC absorption leads to a general reduction of NO2 photolysis rates, whose maximum decreases occur in Asia up to 9% (19%) on an annual (spring) mean basis. The inclusion of BrC absorption reduces the overestimation of single scattering albedo (SSA) in the model, but still the model overestimates the observed SSA by AERONET. To further reduce the overestimation, the sensitivity calculations of SSA are conducted by focusing on the physical properties of Black Carbon (BC), the inclusion of Brown Carbon (BrC), and the size distribution of dust. Large variations in the calculated SSA may result from slight changes of the geometric mean radius, geometric standard deviation, real and imaginary refractive indices, and density of BC. The inclusion of BrC and observationally-constrained dust size distributions also significantly affect the SSA, and result in a remarkable improvement for the simulated SSA at 440 compared with the AERONET observations."

Using Interferometric Synthetic Aperture Radar to Study Permafrost Dynamics by Kevin Schaefer, Permafrost Scientist,  NSIDC 

Abstract:

We measure ground subsidence using Interferometric Synthetic Aperture Radar (InSAR) to study permafrost dynamics.  Permafrost is perennially frozen ground and the active layer is the surface layer of soil that thaws in summer and refreezes in winter.  Permafrost is difficult to monitor using visible remote sensing because it occurs underground.  However, we use InSAR to measure seasonal subsidence resulting from the expansion of soil water into ice as the active layer freezes and thaws each year.  We use the seasonal subsidence to directly measure the Active Layer Thickness (ALT), a key parameter of permafrost stability.  We use Ground Penetrating radar to gather in situ measurements of ALT for validation.  We use the subsidence trends to identify thermokarst features, and important processes, such as the impacts of fire on permafrost.  We use the loss of coherence to measure fire severity.  We combine InSAR with backscatter measurements of soil moisture as part of NASA’s Arctic-Boreal Vulnerability Experiment (ABoVE) field campaign in Alaska and northwest.  Our InSAR techniques can lift the veil to peer under the surface to study permafrost dynamics.

Known Knowns, Known Unknowns, and Unknown Unknowns about Uncertainties in Passive Microwave Sea Ice Data By Walt Meier, Senior Research Scientist, DAAC Scientist, National Snow and Ice Data Center, CIRES, University of Colorado
 
Abstract:
Sea ice data from passive microwave sensors are the basis for one of the longest satellite-derived climate records. While there are many advantages in using passive microwave sensors for sea ice, including complete and consistent daily coverage, there are also many known uncertainties in using the data. These known uncertainties are helpful in guiding use of the data. However, there are many aspects of the uncertainties that are not well known, particularly at the grid cell level. Only recently have some sea ice concentration products started to provide grid cell uncertainty estimates. However, these uncertainty estimates have not themselves been validated – they are unknown unknowns. This talk will focus on recent efforts to validate the concentration uncertainty estimates through comparisons with concentrations derived from visible and infrared imagery. It will also present background on passive microwave sea ice fields and discuss uncertainties in total sea ice extent estimates.
