Policy Implications of Accelerating Warming
If warming is coming more quickly, we need to pick up the pace on policy responses.
There seems to be an emerging scientific consensus that the rate of global warming is rising. After screening out the effects of natural factors like El Niño, scientists have concluded that the pace of warming has roughly doubled since the 1970s. What does this tell us about policy? Some of the implications are more obvious than others, and at least one implication may be unsettling for some climate advocates. Most obviously, we need to accelerate our efforts to carbon emissions. We will be closing in on possible tipping points faster than expected. Climate impacts that we might have expected twenty years from now could hit in half that time.

Key takeaways from the UCLA Emmett Institute’s convening on Solar Radiation Modification (SRM) in Santiago, Chile.
Though interventions like solar radiation modification (SRM) are increasingly breaking into mainstream conversations of climate change, the charged nature of this topic and political extremes that have characterized discussion around it make it difficult for policymakers and decision-makers to find neutral spaces to learn about existing research, ask questions, and brainstorm policy ideas with colleagues and trusted experts. Creating that neutral space was the goal of an Emmett …

The future of environmentalism may include a right-wing, populist strain that is heavily NIMBY
While there is a lot of focus on left-wing NIMBYs in public discourse, there’s also a lot of right-wing NIMBY mobilization too. For instance, the conservative California city of Huntington Beach is leading the resistance to state efforts to require upzoning to facilitate housing. Conservative rural communities are often the locus of opposition to both …

CONTINUE READINGA Landmark Geoengineering Conversation in the Global South
The UCLA Emmett Institute helps sponsor and organize the Degrees Global Forum, the largest event of its kind to date.
I post periodically about developments in the debate over solar geoengineering (SRM) and its potential role in response to climate change. News accounts may suggest that this debate moves fast, but it has three enduring, large-scale themes. First, SRM presents high stakes for climate risks and response – which most governments thus far have been …

CONTINUE READINGThe Politics of Geoengineering Are Getting Stranger
Of all the pollution threats out there, why are state lawmakers and U.S. EPA targeting solar geoengineering?
There are strange things happening in Climate World, in addition to all the horrifying things. Among the strangest is a surge in state bills to prohibit solar geoengineering. Just as strange is the recent shot across the bow by Trump’s EPA Administrator Lee Zeldin against one tiny startup firm that claims to be doing geoengineering. …

A Trump victory would increase the odds that we will ultimately need to start blocking solar radiation as a last resort to limit climate change.
A Trump victory would increase the odds that we will eventually need to “break the glass and pull the red lever.” To be prepared for that possibility, we would also need to do more in the short term to research various forms of geoengineering, their feasibility, and their potential side effects. Basically, if you decide you’re going to start smoking a lot more cigarettes, you need to be prepared for the greater likelihood you’ll need chemo.
CONTINUE READINGAn Ethical Framework for Climate Intervention Research
Can the AGU’s new principles defuse controversy and enable responsible research?
Research into climate intervention techniques, especially solar geoengineering, has long been controversial. Scientists as well as publics and policy makers have been divided on its risks and merits. In recent years, experiments proposed or undertaken in the USA, Sweden and Mexico have triggered vociferous opposition. Growing and unregulated commercial interest in the technologies seems likely …

Marjorie Taylor Greene is wildly wrong about government scientists controlling hurricanes. There is a rich history of weather modification experiments that make that false claim more dangerous.
Since U.S. Rep. Marjorie Taylor Greene tweeted earlier this month that “Yes they can control the weather” — a bunch of commentators have pointed out that she’s wildly wrong. Yes, she’s wildly wrong. No one can make, intensify, or steer hurricanes. No ability to do anything like this is even on the horizon. Her comment …

Multiplying proposals for ice restoration face geopolitical obstacles
Ice-thickening. Glacier curtains. Cloud brightening… Proposals for Arctic climate interventions seem to be multiplying by the day. The changing climate is not only shrinking ice caps and ice sheets, but also bringing much greater than average temperature rises in polar regions. These impacts particularly disrupt the lives and livelihoods of Arctic Indigenous Peoples. Arctic impacts …

The Commission tries to make it OK to talk about – not do – solar geoengineering. Its report proposes a moratorium, coupled with efforts to carefully build knowledge.
In this, my third post on the recently released report of the Climate Overshoot Commission, I’ll discuss their treatment of the most challenging and controversial part of their mandate, Solar Geoengineering or Solar Radiation Modification (SRM). As I noted in my introductory post on the Commission, I served as an advisor to the Secretariat and …
