Climate engineering needs to look at the big picture, says researcher

Of all the different possible methods to combat anthropogenic climate change conceived of so far, among the least studied is climate engineering. An umbrella term for large-scale projects designed to disrupt the Earth's carbon cycle or radiation balance, climate engineering has only relatively recently been included in the conversation about methods that could mitigate the harm caused by carbon emissions.
Research into various climate-engineering projects has grown, but according to Nadine Mengis, who until March 2019 was a Horizon Postdoctoral Fellow at Concordia's Matthews Climate Lab, too few of the studies produced to date have looked at the large-scale side effects these projects would have on interconnected variables.
Mengis, who changed her affiliation to Simon Fraser University this winter but completed her research for this paper while at Concordia, looked at three proposed climate-engineering methods for her study. Here is how each one works, in very broad terms.
