DESCRIPTION:Urban Heat Island Variability in Montreal: understanding curren
 t and future trends using advanced Geospatial analysis\n\nProfessor Raja S
 engupta\n\nWith rising global temperatures\, urban populations\, especiall
 y in densely populated areas\, face higher risk of heat-related illnesses.
  The Urban Heat Island (UHI) effect\, where cities are warmer than surroun
 ding rural areas\, exacerbates this risk. This is very relevant for Montre
 al\, where heat-related casualties are often reported. To understand the i
 ntra-city variability\, we uniquely combine Volunteered Geographic Informa
 tion (VGI) with advanced Geospatial data and analysis to develop novel way
 s of understanding spatio-temporal factors influencing UHI. Furthermore\, 
 future impact on human health is a key concern of UHI. Here\, we propose t
 he development of Agent-Based Models to both study (a) future urban develo
 pment\, including densification following the implementation of specific z
 oning rules\, and (b) how specific individuals may be affected by a combin
 ation of factors\, e.g.\, their residential location as well as personal m
 obility.\n\nRecent changes in sea ice melt onset in the Canadian Arctic\n
 \nProfessor Mallik Mahmud\n\nThe timing of sea ice melt onset (MO) in the 
 Arctic is crucial because it influences the surface energy balance and det
 ermines the amount of sea ice that survives the melt season. In this talk\
 , I will present recent changes in the timing of MO in the Queen Elizabeth
  Islands (QEI)\, located within the Last Ice Area of the Canadian Arctic A
 rchipelago. To provide context\, I will compare the 2015-2024 MO record wi
 th the earlier SAR record (1997-2014) and the long-term passive microwave 
 (PMW) record (1979-2022). This comparison will highlight the varying resul
 ts obtained from different remote sensing sensors and scientific methodolo
 gies\, emphasizing the significance of these advancements in remote sensin
 g technology.\n
