Climate modelling, deep learning and AI
Earth system modelling – and particularly weather forecasting, is in the middle of a disruptive event. The last two years have seen deep learning forecasting methods go from being a promising idea, to keeping up with state-of-the-art approaches to weather forecasting. The new models might be computationally expensive to train, but can be hundreds or […]
Climate denial on TikTok
Social media is a really important means of spreading climate misinformation. I’ve been trying, in a small way, to spread *good* climate information on TikTok for about a year now, and I’ve learned a few things about how the platform works. Getting views The views on my videos have gone from a few hundred views […]
Abuse of climate scientists on social media
I was quoted in this piece in the Observer by Anna Fazackerly, on why climate scientists are being targeted for abuse on social media. Ed’s tweet about it generated lots of interactions, many of them (e.g.) – inevitably – conforming the report’s basic premise. I had an interesting chat with Anna, and I think she […]
Constraining the carbon cycle in a land surface model – a talk for EGU23
I’m attending the EGU 2023 assembly this week, and gave a talk on our latest paper Constraining the carbon cycle in JULES-ES1.0. Attending online works fine, but doesn’t give you all the bonuses of meeting in person, getting the lowdown on the coolest talks coming up, and catching up with old colleagues and friends. One […]
Communicating climate science through social media
I give various versions of this talk to students and other scientists. Get in touch if you’d like me to give it to your organisation – it usually gets lots of good discussions going. The fun thing this year is that TikTok is a mainstream thing now, and Twitter is dying. Going to be an […]
Uncertainty quantification and exascale computing in climate science
I was asked to sit on a discussion panel at this meeting on uncertainty quantification (UQ) with exascale computing. I prepared a short statement (below) on future challenges for UQ at exascale, but I would have made a slightly a longer one (below that) if there was time. A great resource for thinking about the […]
More on surviving social media
I updated this talk [download slides] from last summer (time flies!), offering some personal thoughts on surviving a sometimes-hostile social media environment. [The sound gets better after I decide to hold the tiny mic rather than have it stuck in my shirt.] I was talking to my peers this time, so the mood is somewhat […]
Sensitivity analysis with R
After last week’s post, I thought it might be useful to have some practical examples of how to do sensitivity analysis (SA) of complex models (like climate models) with an emulator. SA is one of those things that everyone wants to do at some point, and I’ll be able to point people here for code […]
Choosing your next design point
You can use the R package DiceOptim to choose the next point to run your expensive simulator. Here’s a gif of function EGO.nsteps() in action, choosing one point at a time, with an initial design of three points. It doesn’t behave in exactly the way I expected, putting lots of points in that well […]
