Global Dimming - The Real Deal

Dr. Peter Carter, Paul Beckwith, and Regina Valdez discuss the complex issue of Global Dimming, also known as the Aerosol Masking Effect or Aerosol Cooling. The focus is primarily focused on those aerosols caused by the burning of fossil fuels and its effects on the climate system and human health.

This video was recorded on July 30th, 2021, and published on October 20th, 2021.

The following topics are discussed:

• The various particle types that make up aerosols and their relative rayleigh scattering properties.
• The cooling effect of aerosols.
• How Global Dimming distracts us from the need to quickly reduce fossil fuel emissions.
• How the smaller aerosol particles, PM2.5, affect human health and mortality.
• The relative amount of time aerosols stay suspended in the atmosphere as a function of whether they reside in the troposphere or the stratosphere.
