Earth system tipping events now seem inevitable – what does this mean for climate governance?
Building meaningful earth system governance creates multiple new research challenges
A tipping point is a system threshold beyond which change becomes self-perpetuating until a qualitatively different stable state is reached. For example a rainforest turns into a grassland, or an ice sheet melts completely. Such shifts are non-linear, and practically irreversible. Fears that growing human impacts might push aspects of the global climate past such …

New Florida Law Strikes Term “Climate Change” From State Laws, Promotes Fossil Fuels & Rejects Renewable Energy Projects
Florida Governor Ron DeSantis, in coordination with an equally myopic and partisan Florida Legislature, has approved new state legislation (HB 1645) that eliminates the term “climate change” from numerous existing Florida statutes that former Republican Governor Charlie Crist signed into law in 2008. The legislation, which takes effect on July 1st, is not just symbolic: …

Duncan McLaren and Olaf Corry reflect on the implications of the UNEA-6 non-decision on solar radiation modification for research and governance
As we wrote in part 1, a Swiss-led proposal to the UN Environment Assembly (UNEA) to establish an expert group on solar radiation management (SRM) proved divisive and was eventually withdrawn. Here we explore why, and what that means for any global conversation about SRM. SRM has long generated concerns that, as a powerful lever …

Duncan McLaren and Olaf Corry observed as diplomats in Nairobi wrestled with a resolution on solar radiation management
In the last weeks, diplomats from all over the world were negotiating more than twenty draft resolutions at the UN Environment Assembly (UNEA). The Assembly is a biennial intergovernmental meeting which sets the global environmental agenda. It also sets the strategy for the UN Environment Programme (UNEP), and outlines policy responses to address emerging environmental …

How should agencies take into account “the things we know we don’t know”?
Since 1981, cost-benefit analysis (CBA) has been at the core of the rule making process. OIRA, the so-called “regulatory czar” in the White House, must approve every significant regulation based on a review of its CBA. But CBA has had a major blind spot. It embodies techniques for analyzing possible harmful outcomes when the probability …

Some activists say “not in my backyard,” but strident opponents of solar geoengineering argue “not in anyone’s backyard.”
A peculiar type of activism is manifesting with regard to solar geoengineering. This proposed set of technologies to reduce climate change has been subject to only a few outdoor experiments. One has been in the pipeline for almost a decade: The Stratospheric Controlled Perturbation Experiment (SCoPEx) would involve the launch of a balloon into the …

Lessons Learned From CalEnviroScreen
Just one week after his inauguration, President Joe Biden designated January 27 “Climate Day” at the White House and signed a number of executive orders, including one aimed to “secure environmental justice (EJ) and spur economic opportunity.” Under this executive order, President Biden took the first steps to make good on his campaign’s EJ commitments. …

My latest article is published by Global Environmental Politics
A set of new biotechnologies are being developed that will force many of us, especially those concerned about biodiversity loss, to re-examine how we understand the relationship between biotechnology and conservation. These are “gene drives,” which would be used to genetically modify, reduce, or eliminate populations of species. My paper “Governing New Biotechnologies for Biodiversity …

Models are crucial to making policy decisions during the epidemic, but you have to know how to use them.
This post works through an exercise in how to use and interpret models of disease spread. Here are the takeaways for policy analysis: You need to know about a model’s sensitivity. Particularly in settings where the specific numbers really matter, such as forecasting how many hospital beds will be needed, it’s important to take into …
