Lack of incentive to guard against risk where one is protected from its consequences.
The formal definition of “moral hazards” applies squarely to insurance. Health insurance is a classic example, and one where moral hazards are pervasive. Equating moral hazards with “moral failings,” they are often used by some on the political right as arguments against government-provided health care.
Environmentalists have their own form of moral hazards, typically applied to new technologies fixing problems without the need for deeper structural and behavioral reforms: band-aid solutions in the form of “technofixes.”... Read more about Green Moral Hazards
The story behind a recent news article reveals how activist groups—with the media’s help—cause misleading and false assertions to arise, persist, and spread.
Much of my work concerns solar geoengineering, a set of proposals to block or reflect a small portion of incoming sunlight in order to reduce global warming. Unfortunately, the discourse is rife with specious, misrepresented, and outright false statements – many of which are consistent with intuition – that are repeated until they acquire a sheen of quasi-truth...
Human rights are often invoked for guiding policy development, especially internationally. Although this occurs in the case of solar geoengineering, it is uncommon to see much beyond a few vague phrases, such as pointing to the need to proceed consistently with human rights. How might human rights help shape the governance of solar geoengineering?
It’s called “re-search” for a reason. You search, you search, and you search again. It also means that researchers will naturally tackle the low-hanging fruits first. Unearthing the harder bits just takes time. That’s the natural flow of things, and solar geoengineering research is unlikely to be different.
The broader implications for solar geoengineering and its possible role in climate policy, however, might well be.
Contrast solar geoengineering with cutting emissions in the first place. The Economics 101 analysis of emissions...
Delegates discussed a draft resolution regarding solar geoengineering and carbon dioxide removal (CDR) at the fourth session of the UN environment assembly (UNEA), which took place from the 11th to 15th of March in Nairobi. The Swiss government put forward the draft resolution with the support of a dozen other countries. The core action proposed by the draft resolution was to “prepare an assessment of the status of geoengineering technologies, in particular,...

Ever since Paul Crutzen broke a long-standing taboo on solar geoengineering research with an essay published in Climatic Change in 2006, the number of publications in the field has increased rapidly. By now there are over 1,500.
We have attempted here to collect and catalog them in an easily accessible...
Before studying the governance of geoengineering, I worked on the governance of human genetic and reproductive technologies. I was thus quite interested, but not too surprised, when reports emerged late Sunday that the first genetically modified babies have been born. It appears that He Jiankui of the Southern University of Science and Technology in Shenzhen, China edited the...

As the visibility of solar geoengineering research grows, we thought it would be useful to provide a publicly accessible record of the solar geoengineering projects that have been funded over the past ten years.
How one defines a solar geoengineering “project,” however, is not straightforward. With a diverse range of efforts having taken place, there are numerous approaches that one could take.
For our purposes, we used the following definition to focus our...
How is this report different from previous IPCC reports?
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...
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.

Welcome to the Solar Geoengineering Research blog. The goal is simple: provide a platform for solar geoengineering researchers and research. By researchers, for researchers.
We realize, of course, that any blog is necessarily a public forum. That is by design. We hope this blog provides a place for discussion between those interested in the topic, regardless of whether they are researchers, journalists, policy makers, policy talkers, or anyone else interested in the latest interdisciplinary takes on solar geoengineering....
