Science Business: NTNU: Geoengineering, other technologies won’t solve climate woes

"The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying on tree planting and alternative technological solutions such as geoengineering will not make enough of a difference."

Phys.org: Crisis management: Seven ways to engineer climate

"'Plan A' remains tackling the problem at its source. But a major UN climate science report released in South Korea on Monday makes it clear that slashing carbon pollution—even drastically—won't be enough to keep Earth from seriously overheating."

UNEARTHED: Can negative emissions really save the world?

"Today, climate scientists at the UN’s Intergovernmental Panel on Climate Change warned that the world needs to radically reduce greenhouse gas emissions to keep the planet within 1.5 degrees of warming by the end of the century. Worried? The boss of a company which has pioneered a way of sucking carbon emissions out of the air wants you to know he’s here to help."

Quartz: A Swiss startup will turn carbon dioxide into stone—for a price

"One of those technologies is direct air capture. It consists of a machine that extracts carbon dioxide from the atmosphere—like a tree, but super-charged—using fans to drive air onto a surface that has a chemical agent which only reacts with carbon dioxide. Once the carbon dioxide is captured, the rest of the air is released."

Hourdequin, M. (2018): Geoengineering Justice

Hourdequin, M. (2018): Geoengineering Justice. In: Science, Technology & Human Values 26 (6), 016224391880289. DOI: 10.1177/0162243918802893.

"Global-scale solar geoengineering raises critical ethical questions, including questions of distributive, procedural, and intergenerational justice. Although geoengineering is sometimes framed as a response to injustice, insofar as it might benefit those most vulnerable to climate-related harms, geoengineering also has the potential to exacerbate climate injustice, especially if control of research, governance, and potential plans for deployment remains concentrated in the hands of a few. The scope and scale of solar geoengineering, the diverse concerns it raises, and the lack of consensus surrounding it pose particular challenges for justice."

Vimeo: ‘Dirt Rich’ — The Importance of Biochar and Regenerative Systems for Soil Health

"Dirt Rich shifts focus from greenhouse gas emissions to carbon drawdown which is the only viable solution for reversing the effects of runaway global warming in a timely manner. Through exploration of geo-therapy strategies, Dirt Rich shines a light on their value and beauty which undeniably are our last hope for protecting life as we know it on this challenged planet. Through regenerative agricultural practices, reforestation of abandoned land, protection/restoration of carbon-rich wetlands and keystone species, Dirt Rich illustrates how implementing these strategies will return our atmosphere to safe levels of carbon while growing soil, our most precious resource."

Iron Salt Aerosol Australia Pty Ltd: Iron Salt Aerosol. Copying Mother Nature to Cool the Planet

"Iron Salt Aerosol (ISA) could be the single best way to help stop global warming.  Adding 200,000 tonnes of iron to the air could remove 12 gigatonnes of carbon dioxide and equivalents each year, double the abatement of the whole Paris Accord over the next decade. ISA could be implemented safely, quickly and at low cost, below a dollar a tonne of abated CO2, if we get positive results from field trials."

Kovenock, M.; et al. (2018): Leaf Trait Acclimation Amplifies Simulated Climate Warming in Response to Elevated Carbon Dioxide

Kovenock, M.; Swann, A. (2018): Leaf Trait Acclimation Amplifies Simulated Climate Warming in Response to Elevated Carbon Dioxide. In: Global Biogeochem. Cycles 165 (2), S. 351. DOI: 10.1029/2018GB005883.

"Here we show that one leaf trait acclimation in response to elevated carbon dioxide—a one‐third increase in leaf mass per area—significantly impacts climate and carbon cycling in Earth system model experiments. Global net primary productivity decreases (−5.8 PgC/year, 95% confidence interval [CI95%] −5.5 to −6.0), representing a decreased carbon dioxide sink of similar magnitude to current annual fossil fuel emissions (8 PgC/year)."
