PSU Study Uncovers Factors Behind the Shrinking of the Great Salt Lake

The Great Salt Lake in Utah faces an environmental crisis as it reached an alarming record low water level in 2022.
New studies from Portland State University are showing the key factors to this issue. The research could be useful for future planning and management of the lake ecosystem.
Siiri Bigalke, the lead author of the study and a Ph.D. candidate in PSU's Earth, Environment, and Society program, emphasized the importance of the Great Salt Lake in the local and regional economy.
The lake generates over $1.9 billion annually and is vital for millions of migratory birds and contributes to the snowpack in the Wasatch Mountain Range.
The research used a computational model to simulate changes in the lake's volume over time and revealed that increased evaporation due to higher temperatures plays a dominant role in the decline.
Reduced streamflow accounts for about two-thirds of the total decline in lake volume, and increasing streamflow could potentially boost lake volume in the near term.
However, under continued warming scenarios, higher evaporation rates are likely to counteract these gains and lead to greater long-term water loss.
The lake's dwindling water levels also pose health risks to the local populations. The exposed lakebed can contribute to toxic dust that worsens air quality.
The study advocates for further research on local evaporation rates, precipitation patterns, and human interventions to develop adaptive strategies that can mitigate further deterioration of the lake and its ecosystems.
The research is documented in a paper published in the journal Geophysical Research Letters.
Action must be taken to address the multi-faceted challenges posed by this environmental crisis, ensuring the lake's ecological and economic contributions are preserved for future generations.

Childhood Poverty and Parental Mental Health Issues Linked to Increased Risk of Teen Violence and Police Encounters

Children growing up under persistent poverty and parental mental health issues are more likely to involve in violent behavior and engage with law enforcement by the age of 17, says recent research.
The research was conducted by studying data from the UK Millennium Cohort Study, involving over 9,000 children and scratching instances of family adversities and poverty till they turn 14.
Teenagers who were exposed to poverty and poor mental health were 2 times more likely to carry or use weapons than those from a stable background.
Adolescents exposed to adversities were more than 5 times more likely to find themselves under arrest and 3 times more likely to receive warnings or cautions than their peers.
Approximately one-third of weapon-related behavior and nearly a quarter of police contacts among 17-year-olds throughout the UK can be attributed to early childhood adversities, say researchers.
Researchers advocate for comprehensive, whole-system approaches, that support families grappling with economic hardships and mental health challenges, including community programs that provide mental health support and economic assistance to families in need.
Such strategies will create nurturing environments, free from the shadows of poverty and mental health issues that will foster positive development and resilience among young people.
Understanding the dynamics of adversity and its effects provides necessary impetus to create lasting change in the lives of vulnerable youth.
Early interventions can help prevent violence, build healthier, more resilient young individuals and contributes to a healthier future for society.
