AGU 2012


If you’d like to find out more about the results on my poster, the best thing is to talk to me! If I’m not around, please do send me a message and I will reply asap.

On this site you’ll find information about my other research areas – do ask me about crop and tree canopy capacity, crop albedo geoengineering, food security, human evolution and climate, the origins of farming and other past human – climate – environment interactions ~200kyr to 10kyr.

I also like mountain biking, road biking, hill walking, running and kite surfing, so feel free to chat to me about these things too!

AGU 2013 canopy interception capacity


If you missed seeing me at AGU, or just would like closer look at the work I’m doing at the moment, you can download a copy of the poster.

Normal provisos apply – this work is submitted to a journal, it is yet to be subject to peer review, etc. etc.

If you’d like to know more about this work, please do contact me.

AGU 2013: The importance of 400 ppm CO2

Rather belatedly, Catherine Bradshaw and I wrote a summary of the 400 ppm sessions on the physical science of 400 ppm (Catherine’s session) and on the communication of 400 ppm climate for the Cabot Institute blog.

I don’t have much to add to it, except to say thank you to Catherine, whose original concept it was. Thank you too to Kent and Casey, who were excellent co-convenors.

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.

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.

BRIDGE group talk: Coupled climate model sensitivity to canopy interception capacity

BRIDGE is the group I belong to at Bristol, which has a lot of people who do Paleo modelling, use paleo proxy data and many people whose primary interest is the ocean. I’m one of a small number who are interested in the future and/or the land surface. So giving a talk on canopy interception capacity makes BRIDGE a tough audience as they aren’t, on average, especially interested in my area of research.

So I gave a different angle to my work with an alternative title of ‘How a parameter no one knows or cares anything about, can significantly alter the global climate’. This drew a good number of people and we had a lively discussion about HadCM3.
