DESCRIPTION:The speaker this week will be Dr. V. 'Ram' Ramaswamy (pre-recor
 ded).  The talk was originally presented in 2020 when Dr. Ramaswamy was aw
 arded the 2020 AGU Jule Gregory Charney Lecture prize. Title: “Aerosols an
 d their Gaming of the Climate System: Microscale presence to Macroscopic i
 mpacts.'Abstract:Jule Charney was visionary extraordinaire in synthesizing
  theory\, modeling\, and observations to address key questions in the atmo
 spheric and climate sciences. Recalling the Charney spirit in this lecture
  for one of the principal contemporary challenges\, we focus on the role o
 f atmospheric aerosols in the climate system. The manner in which aerosols
  have exerted their influence on the climate system stands in sharp contra
 st to other climate drivers e.g.\, well-mixed greenhouse gases. Natural an
 d anthropogenic tropospheric aerosols\, and stratospheric aerosols\, span 
 a diverse range in characteristics. Advances in theory\, modeling and obse
 rvations have led to major insights into aerosol effects on the atmospheri
 c general circulation\, and surface heat and moisture budgets\, measured a
 gainst unforced variability and other drivers. The perturbations in atmosp
 heric aerosol composition\, including the important interactions with clou
 ds\, alter the radiative balance\, diabatic heating\, temperature and prec
 ipitation. Causal understanding of climate trends over the past several de
 cades indicates that anthropogenic tropospheric aerosols have counteracted
  greenhouse gas effects to a significant extent globally and regionally\, 
 traceable through the thermodynamic and dynamic responses. The understandi
 ng of 20th Century aerosol pollution and climate effects reveals the poten
 tial influences for the 21st century climate response to emissions scenari
 os\, with ramifications for solar radiation management issues. The recent 
 COVID-19-associated decrease in emissions offers another striking incidenc
 e of discernible aerosol perturbations. The climate perturbation by aeroso
 ls reminds us of an important Charney legacy (the 1979 National Research C
 ouncil report). Charney's optimism and collegiality\, together with his br
 illiance in forging the community's thinking on important questions\, infu
 ses enthusiasm even today in addressing the pressing climate challenges of
  our times.Event Webpage: https://us.bbcollab.com/guest/4a2dc489c4ad41729b
