"Climate change, former US Secretary of State Rex Tillerson once said, is “an engineering problem, and it has engineering solutions.” Following President Trump’s withdrawal from the Paris Agreement on climate, an idea has been catching on among Republican politicians and climate researchers alike – geoengineering. In other words: What if we reversed global warming simply by redesigning the atmosphere?"

"There is also a set of proposed technologies that could keep global warming within these or other limits. Through these techniques, we could intentionally alter the earth’s radiative balance, cooling the planet and counteracting anthropogenic climate change. That is, we could make the planet more reflective, block some incoming sunlight, or increase the amount of outgoing infrared radiation."

"Geoengineering refers to a set of emerging technologies that could manipulate the environment and partially offset some of the impacts of climate change. Solar geoengineering in particular could not be a replacement for reducing emissions (mitigation) or coping with a changing climate (adaptation); yet, it could supplement these efforts."

"Soil leads the solutions for negative emissions in a new climate change report. Soil carbon sequestration was among the cheapest methods with the greatest potential."
