University of Michigan Glaciologist interested in climate change, ice sheets, sea level rise and equitable adaptation and mitigation | he/him/his |
I have been vigorously lobbying for a Crime Scene Investigation Antarctica (CSI-Antarctica) for the past decade, but the networks seem strangely uninterested.
Glaciologists are "kind of like one of those crime shows…‘Who Killed the Ice Shelf?’"

Alright let me tell you a story about a prominent scientist in my field and my first conference. This was in the days when most had adopted PowerPoint, but some of the older folks still showed up with actual physical slides to show on one of those old fashioned overhead projectors.

The question isn’t will the seas rise, but what are we going to do about it because even the most optimistic projections tell us that sea levels are going to continue to rise and it increasingly looks like the more pessimistic scenarios are more plausible.
I was interviewed for this great piece about sea level rise.
Solid reporting here on the scientific controversy, but I like that Evan ended with my bigger picture quote that a lot of the controversy doesn't really matter because by 2100, we will be talking about a radically different coastline.

The uniquely vulnerable West Antarctic Ice Sheet holds enough water to raise global sea levels by 5 meters. But when that will happen — and how fast — is anything but settled.

Most climate scientists strongly believe our mission is to provide better climate information for decision making. The mantra at every meeting is let’s reduce uncertainty and provide full probability distributions!
My soapbox for today is that physical climate scientists need to be exposed to qualitative methods.

It should be obvious to everyone, but for the hedge fund managers at the back, a compact that restricts academic freedom isn't about merit or access. The goal is control and a return to a segregated system where elite institutions solely serve the interests of the wealthy. 1/

This isn't important, but I'm getting tired of academics using "climate" and "sustainability" interchangeably. There is overlap between climate and sustainability work. Conflating the two and not being precise about what you mean creates confusion.

Here are some takeaways from the panel on AI and climate. AI is being used to speed up some research tasks, but this comes with significant costs. Those costs includes the environmental impact, which can be immense and will be paid by future generations. 1/
Panel on AI and climate actually went well? At the end I had the audience and panelists get up and move to one side of the room or the other depending on whether they thought AI was a net harm, neutral or positive for society. That is a real histogram.
I am scheduled to moderate an AI and Climate panel tomorrow for climateweek at umich and, remembering that I thought the iPhone would bomb and picked betamax over VHS, I might be the worst choice to moderate any tech related conversation.

Heat kills more people than flooding, but we invest way more money in preventing flooding than cooling people. Strategies like more air conditioning, accessible cooling centers and strategic green space are all effective at reducing mortality and need to be promoted.

Alright so I think after the RFK hearing, the DoE climate report, attempt to rescind the EPA endangerment finding and *waves hands* everything, it is clear that we are seeing the most sustained attack on science in my lifetime. And, believe me, I’ve seen some shit.

The sea level rise chapter is silly. You can’t infer global sea level rise from a handful of tide gauges in the US because global sea level is *global*. 1/
Ch7 moves to sea level rise, focusing (and we're seeing a pattern now) on noisy data from individual tide guages - ignoring global data from satellite altmetry which identify with high confidence a global-scale acceleration in sea level rise. www.climate.gov/news-feature...

Columbia now has a vice provost for authoritarian compliance.
As part of the $200 million deal Columbia made with the Trump administration, an outside monitor will assure the school complies. To critics, this represents an unprecedented governmental intrusion into the affairs of a private university.

Folks, the lifetime of CO2 in the atmosphere is centuries and overshoot scenarios involve CO2 emissions shooting above the threshold and then dropping below again *this* century.
Lots of talk about overshoot scenarios where we zip past temperature thresholds before coming down and stabilizing. We all agree that there is no remotely plausible technology or mechanism that would suck out enough CO2 to allow our emissions pathway to come back down right?

Once again, I'm begging people to recognize that nearly 84% of students attend "non selective" colleges and universities.
one of the things that gets me about so many of the pundits who pontificate about "higher education" when they really mean a handful of elite private institutions is that most of them live within driving distance of either a community college or a non-selective public institution
