David Keith Has an Idea to Slow Global Warming: Geoengineering
Climate change is a pressing issue that has been gaining more attention in recent years. With rising global temperatures, extreme weather events, and melting polar ice caps, it’s clear that action needs to be taken to slow down the effects of global warming. While many solutions have been proposed, one idea that is gaining traction is geoengineering, and David Keith is at the forefront of this innovative approach.
David Keith is a Canadian physicist and professor at Harvard University who has been studying geoengineering for over a decade. His research focuses on finding ways to manipulate the Earth’s climate to reduce the impacts of global warming. While some may see this as playing “God” with the environment, Keith believes that geoengineering could be a crucial tool in our fight against climate change.
So, what exactly is geoengineering? It refers to deliberate large-scale interventions in the Earth’s systems to mitigate or reverse the effects of climate change. There are two main types of geoengineering: carbon dioxide removal (CDR) and solar radiation management (SRM). CDR aims to remove excess carbon dioxide from the atmosphere, while SRM attempts to reflect sunlight back into space to reduce the amount of heat trapped on Earth.
Keith’s idea for slowing global warming revolves around SRM, specifically a process called stratospheric aerosol injection.
