Should There Be a ‘Non-Use’ Agreement on Solar Geoengineering?

Volcanic eruption (Sarychev Peak)

Why I signed the call for a non-use agreement, and what that might mean for research.

Although I’m a newbie at the Emmett Institute, I have been working on geoengineering for a decade now. I have heard countless arguments over whether and how solar geoengineering could be useful in the struggle to manage climate change. I have seen deeply misleading claims by both its supporters and detractors, many trying to coopt …

This Climate Debate is a lot of Hot Air

Geoengineering is having a moment. But much of the media coverage is failing to capture the actual debate.

We’ve been hearing a lot lately about geoengineering – the various scientific theories and governance ideas that could eventually lead to technological interventions to help cool the planet. A weather balloon stunt in Mexico by a small startup called Make Sunsets generated a lot of hot headlines, even though that solar geoengineering “experiment” was so …

Is Bipartisanship Possible?

An image of the U.S. Capitol Building in the evening.

It’s not easy in today’s polarized politics. But maybe it’s not completely off the table.

We are now, as so often, in a time of divided government. That makes bipartisan cooperation necessary. We are also in a time of hyper-partisanship.  The problem may be compounded by the concessions made by McCarthy to the far Right in order to become Speaker.  Nevertheless, there may be some opportunities for cooperation across party …

A Dangerous Disruption

A startup firm proposes to sell dubious carbon credits from stratospheric aerosol injection

Last week, MIT’s “Technology Review” reported that a small startup firm is proposing to spray reflective aerosols in the stratosphere commercially as a climate corrective. (Stratospheric Aerosol Injection or SAI.) Previously announced online in the Google Geoengineering Group, the firm is small and new, operating with a claimed total of $750K of venture financing. They …

Keep on Trucking

A new rule will clean up exhaust from new diesels, a major health threat.

Last week, EPA finalized its new rule imposing emission limits on new heavy trucks. The new regulation was clearly a massive undertaking. EPA’s formal announcement of the new rule is 1100 pages long. The accompanying summary of comments on the proposed rule and EPA’s responses is another 2000 pages. This is partly due to the …

Stanford’s Sustainability School: A Good Model?

There are pros and cons, but it makes sense to bring the university org. chart into the 21st century.

In my last post, I wrote about universities like Stanford that are creating new programs in sustainability.  Stanford’s move may inspire others to follow.  There are pros and cons, but it seems inevitable that the organization of universities will ultimately take account of one of the biggest problems facing humanity. Administrative reorganizations, whether in government, …

The Revolution, the Enlightenment and the Climate Crisis

The Founding Era’s belief in facts and science has too often been replaced with political identity as a test of truth.

The Declaration of Independence is a document deeply rooted in the Enlightenment. The Declaration begins with a note of cosmopolitanism, referring to “a decent respect to the opinions of mankind.” There is then the famous passage declaring “these truths to be self-evident, that all men are created equal, that they are endowed by their Creator …

Why Energy Conservation Will Remain Crucial

Even after switching to clean power, we’ll still need to limit energy use.

If we switch to renewables, we won’t need to worry about saving energy. Right? Wrong! One reason to save energy is to limit carbon emissions from the energy we  use. That’s going to important until the energy system has been completely cleaned up. But energy conservation is important for reasons that go beyond the direct …

Future Shock

The latest IPCC report contains crucial new information about how soon and how bad climate impacts will be.

When the IPCC released its latest climate science report a few weeks ago, many commentators observed that the report should heighten our sense of urgency about climate action. Most of that discussion was at a very general level. It’s worth taking a closer look at some key findings and their policy implications. Here, I want …

Can we govern large-scale green infrastructure for multiple water benefits?

Yolo Bypass Aerial View

by Lidia Cano Pecharroman, Christopher Williams, Nell Green Nylen, and Michael Kiparsky

Green infrastructure is increasingly emphasized as an alternative, novel path for water infrastructure. The possibilities are intriguing: Can we transition from a landscape dominated by siloed grey infrastructure (think concrete and steel, constructed for one or a few key outcomes like water supply or flood control) to one that centers natural processes in water infrastructure …
