Professor Joyce Penner Discusses Geoengineering in Christian Science Monitor Article

Climate & Space Professor Joyce Penner was recently interviewed by the Christian Science Monitor for an article about the rise of the planet's atmospheric carbon concentrations. According to National Oceanic and Atmospheric Administration (NOAA), the concentration of carbon dioxide rose by 3 parts per million (p.p.m.) for the second year in a row in 2016, bringing the average concentration to a record-setting 405 p.p.m. 

Some scientists have suggested taking a geoengineering approach to counter the dramatic rise on CO2. 

An excerpt from the article: 

“The US Global Change Research Program (USGCRP) published a 119-page report in January, two paragraphs of which were devoted to recommending, for the first time, preliminary research into what it called ‘climate intervention.’ Specifically, it suggested investigating the effects of modifying Earth’s reflectivity and a technology called carbon dioxide removal so that ‘deliberative climate intervention may someday be one of a portfolio of tools used in managing climate change.’

“Even supporters of so-called geoengineering are wary of climate interventions because of their poorly understood effects and the risk some may interpret them as a carte blanche to ignore climate change’s root causes.”​
