Geoengineering science is advancing, but the question remains – should we use it?
The released Monday presents a major leap forward in predicting how geoengineering to limit global warming might affect the planet, although scientists said the greatest hurdle remains, deciding whether to use the controversial methods.
Geoengineering involves large-scale interventions that shift the climate, generally with an aim of cooling the earth.
The United Nations panel addressed two types of geoengineering in the report – solar radiation management and greenhouse gas removal.

But the report makes no recommendations on whether to use either method. The panel could give guidance on how decisions on geoengineering should be made in another report due in 2022.
Solar radiation management techniques generally control how much sunlight is reflected back out into space, preventing it from heating the earth.
