The Paris Agreement set a target to limit global warming to "well below 2 degrees, but preferably to 1.5 degrees celsius compared to pre-industrial levels."  However, if present trends continue the world is set to blow past those international targets.

This has lead scientists, the policy community and ethicists to consider strategies on climate change that assume the Paris Agreement targets will not be met in time.  This includes the technological innovation called "Solar Radiation Modification," which can include the injection of aerosols into the atmosphere to essentially block heat from reaching the earth.  

And to that end, my guest today, Janos Pasztor has done some important work on Solar Radiation Modification for global governance and climate justice. He is the executive director of Carnegie Climate Governance Initiative and we kick off discussing what me mean by a global warming overshoot scenario that may necessitate the use of this potentially controversial Solar Radiation Modification Technology.
