iLeaps Conference

iLeaps (Integrated Land Ecosystem-Atmosphere Process Study) have a conference every four years, so it’s an opportunity not to be missed.

I gave a talk on Climate Engineering with Nitrogen fertilisation, which has generated a good bit of discussion. I also caught up with a lot of colleagues from CEH and the Met Office and other places, which has been great.

 

 

ICDC10 Conference

In the superlatively beautiful Interlaken in Switzerland, I was lucky enough to attend the tenth International Carbon Dioxide Conference (they only happen every four years).

Highlights

  • talking about ocean acidification from nitrogen with Helmuth Thomas
  • chatting to people at my poster about the moral ambiguity of climate engineering with nitrogen
  • the conference dinner with Jed Kaplan, talking about pre-historic land use change (the so-call early anthropocene)
  • long discussions with Sonke Zeahle about all things nitrogen

AGU 2016

This year at AGU I was kept busy with chairing a session on Land-use change and giving a talk on biodiversity over the last 300 Ma.

I was the organising convenor for the land-use session, which was very successful, with two oral sessions and over 50 abstracts submitted. There was a who’s-who of LUC, with talks from Julia Pongratz, Dave Lawrence, George Hurtt, amongst others.

My talk was on Biodiversity of Terrestrial Vegetation during Past Warm Periods, showing some work I’ve been doing with a DGVM called JeDi which has enough vegetation types that inferences can be made about changes in biodiversity.

AGU 2015

A last minute decision to go to AGU gave me a rare opportunity to go to this conference without the stress of having to present. So I had a load of fun going to lots of seriously interesting sessions on Nitrogen, land-use, and vegetation dynamics, and also meet up with lots of people. That last one is where most of my favourites and most thought compelling talks and posters were, and that seems to be where I am headed at the moment.

Jules meeting 2015

The defining aspect of the Jules meeting is the discussion: sometimes intense and often loud, there is a mix of mercy, generosity and harsh honesty that I feel is motivated by science and practicality rather than ego.

I was kept busy catching up with people as ever, explaining what I’m working on now including a poster with some initial results for the new Jules terrestrial Nitrogen component that will go into version 4.4 and ultimately UKESM1. At the request of the organisers, I also chaired the ‘Soil Processes’ session. A typically lively session there were great talks from Eleanor Burke, Sarah Chadburn, Graham Weedon and Anna Verhoef.

A particular highlight for me was Menard’s talk on Meteorological forcing, ancillary data and evaluation methods as sources of errors and uncertainty in land surface models. She found that incorrect switch choice in the namelists and different driving data were major (read huge) sources of errors in jules. In essence, Jules is a good model, if used correctly, but ‘used correctly’ is dependent on a lot of settings that are not always obvious. This provoked a very interesting but quite heated discussion.

 

Transformational Climate Science

Very likely to be the first conference to deal with WG1, WG2 and WG3. Love some IPCC puns. 🙂

This was a great day of talks, some of which summarised some of the key points of the working groups, and some went a bit further, talking about what the point of the IPCC ARs is, and what is coming next. Highlight for me was Corinne Le Quere’s talk. She was great.

EGU 2014

I talked at EGU on the Monday afternoon about some work which shows that the different RCP scenarios have different sensitivities to land use change. The other land surface sessions, many sponsored by iLeaps, were later in the week.

I saw some really interesting work and met up with some familiar faces (from CEH, Max Planck and many others, as always some of the people from Bristol that I don’t see as often as I’d like).
