"Last week, Harvard University researchers announced the cancellation of a high-profile solar geoengineering experiment, frustrating the project’s supporters. But advocates say that all is not lost, and that momentum for evaluating ways to artificially cool the planet is building internationally....But the project faced opposition from those concerned about unintended and potentially global consequences. Critics, including many academics, say that solar engineering is too risky and could reduce pressure on world leaders to eliminate greenhouse-gas emissions by offering a ‘plan B’."
Thank God, they cancelled their insane plan. They're worried about a possible rise of a couple of degrees over a century, but their "experiment" could have been disastrous, particularly because we may be headed into the next mini-ice age within the next few decades.
