Wired: Could we reverse global warming by redesigning the atmosphere?

"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?"

TechCrunch: At what point do we admit that geoengineering is an option?

"We already know how to cool the planet without reducing carbon. The solution is so simple it’s almost laughable: just make our clouds a little more reflective, so they reflect more of the sun’s light, and thus reduce our heat."

Legal Planet: Another Possible Means To Keep Global Warming Within 1.5 Degrees Celsius

"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."

Quartz: Trump signed a landmark bill that could create the next big technologies to fight climate change

"The budget bill passed today included a lot of extra defense spending. In return for scratching the Republicans’ back, Democrats secured a slew of spending and tax credits on health care, education, and clean energy. Some of these had huge Republican support, such as the 45Q tax credits for carbon capture and 45J nuclear-power production credits."

NextBigFuture: Funding and research on geoengineering and climate change mitigation

"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."

Harvard University Blog: Less rain but still wetter and greener?

"Offsetting global warming with solar geoengineering would likely weaken the water cycle and reduce regional precipitation which has raised concerns that it could lead to droughts. However, changes to plants under high CO2 concentrations could mean that a geoengineered world would be on average greener and wetter."

Phys.org: Why we can't reverse climate change with 'negative emissions' technologies

"Featured prominently in the report is a discussion of a range of techniques for removing dioxide from the air, called Carbon Dioxide Removal (CDR) technologies or negative emissions technologies (NETs). The IPCC said the world would need to rely significantly on these techniques to avoid increasing Earth's temperatures above 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, compared to pre-industrial levels."
