DESCRIPTION:Dr. Agnieszka Skowron\nDr. Edward Gryspeerdt\n\n\nAviation imp
 acts on climate\nPresented by Dr. Agnieszka Skowron\, Research associate a
 t Manchester Metropolitan University\n\nAviation is representing approxima
 tely 3.5% of the total current radiative impact on climate\, despite being
  responsible for only 2.4% of global annual emissions of CO2. The recent C
 OVID-19 pandemic had a small climate effect and is projected to only delay
  aviation’s contribution to warming. Aviation is also responsible for no
 n-CO2 emissions\, one of the main concerns over aviation’s effects on cl
 imate. These emissions affect atmospheric composition and change cloudines
 s\, which in turn affects the radiative balance of the atmosphere. The lar
 gest non-CO2 effects from aviation on climate are the formation of contrai
 l cirrus and the effects on atmospheric chemistry from NOx emissions. The 
 net non-CO2 effects represent approximately 2/3 of the total aviation forc
 ing to date\, but their future contribution might change. \n\nCovid\, con
 trails and climate chang\nPresented by Dr. Edward Gryspeerdt\, Royal Socie
 ty University Research Fellow at Imperial College London\n\nUnlike greenho
 use gases\, contrails (line shaped clouds formed by aircraft) are an easil
 y visible human-driven warming of the climate system. The total magnitude 
 of the warming from contrails is highly uncertain\, but is approximately e
 qual to the warming from all greenhouse gases emitted from every aircraft 
 since the dawn of flight.\n\n\n\nThe shutdown in aviation due to the COVID
 -19 pandemic and new satellite data provide a unique opportunity to measur
 e the warming impact of aviation on the climate. From tracking the impact 
 of individual aircraft to observing large scale changes in cloud\, satelli
 tes find large impacts of aviation on clouds and show us which types of ai
 rcraft have particularly large warming impacts on the climate. With a wide
  range of initial conditions\, contrails can also give us an insight into 
 the impact of aerosol perturbations on natural cirrus clouds\n\n\n\n\n\n
