Dear colleagues,</div><div><br></div><div>The <a href="https://jasperfkok.com/" target="_blank">Aerosol–Climate Interactions group</a>
 at UCLA is seeking a postdoctoral scholar to study the climate response
 to targeted wintertime polar cooling. The position is part 
of a <a href="https://www.simonsfoundation.org/funded-project/exploring-the-potential-for-regionally-cooling-the-earth-by-seeding-wintertime-mixed-phase-clouds/" target="_blank">Simons Foundation-supported project</a> assessing mixed-phase cloud thinning as a proposed climate-intervention 
concept. The project does not assume that this approach is feasible, 
desirable, or deployable; its goal is to determine how the Arctic and 
global climate system would respond, including effects on sea ice, 
hydrology, AMOC-relevant ocean stratification, time of emergence, and 
Arctic-community-relevant climate variables. The full job ad is <a href="https://jasperfkok.com/wp-content/uploads/2026/05/ucla-postdoc-in-arctic-climate-dynamics-and-intervention.pdf" target="_blank">here</a>.

</div><div><br></div><div>
The position offers substantial intellectual ownership, access to UCLA 
and NCAR high-performance computing resources, and collaboration with 
colleagues at UCLA, Scripps, and the University of Maryland. A summer 
2026 start date is preferred, and U.S. citizenship or permanent 
residency is not required. Applications received by May 20, 2026 will 
receive full consideration, but applications will be reviewed until the 
position is filled.
