Harvard University Blog: Reflections on the IPCC special report on pathways to and impacts of 1.5°C

"The main difference to previous reports issued by the Intergovernmental Panel on Climate Change (IPCC) is that this report focuses on the 1.5°C target, while the the Fifth Assessment Report did not pay much attention to it, largely because too few studies even addressed this ambitious scenario. The Paris Agreement and the request to the IPCC for this latest special report have changed this: more and more studies have considered how the goal could be achieved – with similar results, but greater urgency."

MacMartin, D. G.; et al. (2019): The Engineering of Climate Engineering

MacMartin, D. G.; Kravitz, B. (2019): The Engineering of Climate Engineering. In: Annu. Rev. Control Robot. Auton. Syst. 2 (1). DOI: 10.1146/annurev-control-053018-023725.

"While reducing anthropogenic greenhouse gas emissions remains the most essential element of any strategy to manage climate change risk, it is also in principle possible to directly cool the climate by reflecting some sunlight back to space. Such climate engineering approaches include adding aerosols to the stratosphere and marine cloud brightening. Assessing whether these ideas could reduce risk requires a broad, multidisciplinary research effort spanning climate science, social sciences, and governance."

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."

Chhetri, N.; et al. (2018): Governing Solar Radiation Management

Chhetri, N.; Chong, D.; Conca, K.; Falk, R.; Gillespie, A.; Gupta, A.; et al. (2018): Governing Solar Radiation Management. DOI:10.17606/M6SM17

"This report offers a detailed examination, by a team of global governance experts, of governance needs and options for Solar Radiation Management (SRM) technologies. The report focuses on near-term governance, outlining feasible and needed actions that can be taken by approximately 2025, at the national, regional, and international levels and by non-state actors."

Harvard University Blog: Designer Climates?

"When I first started working on this topic in 2008 as Alan Robock's Ph.D. student, I had no idea how to answer these questions, but I knew they were important. I had seen his 2008 study, which showed how solar geoengineering could negatively impact the Indian and East Asian monsoon, which supplies water to literally billions of people. I too was concerned about winners and losers in solar geoengineering and the potential for conflict over optimizing the climate."

IASS: IPCC Special Report: IASS Recommendations for Climate Protection and the Energy Transition

"Scientists at the IASS conduct research across a range of climate-related issues: climate governance, climate geoengineering, air quality, mitigation of climate-forcing pollutants, the international energy transition, the coal phase-out, and structural transformation. Which measures can slow global warming and help us to achieve the 1.5°C target?"

news.com.au: Extreme measures the world may have to consider if it doesn’t act on climate change

"THE world seems incapable of taking decisive action on climate change but we may soon have to consider some bizarre options to stop global warming if we fail to act. The Paris Agreement sets a target of well under 2 degrees celsius warming and researchers decided to look at how much it would cost to achieve this target, and the more ambitious target of 1.5C, as well as what the potential benefits were."

Science News: Big increase in economic costs if cuts in greenhouse gas emissions are delayed

"A comprehensive new analysis involving researchers from UEA warns that the target of limiting global warming to 1.5ºC could soon become too economically expensive to justify, despite the benefits it could provide."
