Open University Geological Society

Last Saturday (21st January) the West Midlands Open University Geological Society held a day of lectures at the Department of Earth Sciences, University of Birmingham. I was one of five invited speakers who covered a wide range of topics related to geology: Snowball Earth (McMillan, Birmingham), earthquakes in Chile (Ryder, Liverpool), salt mines of Cheshire (Carlon), Icelandic eruptions (Watson, Bristol) and myself on glacial-interglacial cycles in the tropics. The Dome lecture theater was full and it was exciting to be able to engage OUGS members directly with reaserch being conducted in the Palaeoenvironmental Change Research Group at The OU. Therefore, many thanks to Ron Whitfield for inviting me and organising the event. I will certainly be recommending attending and speaking at these events to my departmental collegues.

Hutton Club

On Friday I had the privilege of presenting research from the Palaeoenvironmental Change Research Group to the Hutton Club at the University of Edinburgh (Institute of Geography). My talk, entitled “Assessing the impact of Quaternary glacial-interglacial cycles in the tropics”, drew on: 1) empirical data on past vegetation change from sedimentary records spanning multiple glacial-interglacial cycles; Lake Titicaca (370,000 years), Erazo (middle Pleistocene) and Lake Bosumtwi (500,000 years), and 2) model climate-vegetation data from the GENIE-1 model. The combination of these new long tropical records with model data strongly suggests that the long-term pattern of vegetation response to global glacial-interglacial cycles is differently structured at low-latitudes when compared with mid-latitudes. The different pattern of change suggested in response to past global climate variation might suggest that the response of tropical vegetation change to predicted future climate change could be different to that anticipated for mid- and high-latitudes.

Biodiversity & Ecosystem Services

PAGES (Past Global Changes)
Focus 4: (Past) Human-Climate-Ecosystem Interaction (PHAROS)
Biodiversity Theme Workshop at the Department of Zoology, University of Oxford (9-11 Jan)

Using fossil records to map potential threats, opportunities and likely future developments for biodiversity and ecosystem services
Organised by: Dr. Elizabeth Jeffers, Dr. Shonil Bhagwat and Prof. Kathy Willis

This small (about 30 attendees) workshop brought together academic researchers mainly working in the field of past environmental change to discuss the use, and potential use, of data sets in understanding the key environmental challenges facing society. The bulk of the discussion took place with reference to ‘ecosystem services’. Three types of ecosystem service were mentioned early on for which it was thought that the fossil record can provide a unique long term perspective (beyond historical records): 1) provisioning services (e.g. food, timber, biofuels), 2) regulating services (e.g. carbon), and 3) cultural services (e.g. national parks, tourism).

Below I will summarize some of the issues discussed. Please note that this does not cover the full range of discussion or all of the many high quality contributions. For further information click here to visit the workshop web page.

Quaternary hindsight

Quaternary – the last 2.6 million years of Earth history (click here for more detailed definition)
Hindsight – knowing what to do after the event

The 2012 Annual Discussion Meeting of the Quaternary Research Association, entitled Quaternary Science & Society, focused upon:

  1. The way in which observations of past environmental change can serve as “hindsight” with regard to the consequences of ongoing and predicted environmental and climatic change, and
  2. How scientists might best communicate scientific method and research findings effectively beyond academia, e.g. for policy makers, geoscience professionals and the general public.

Given the nature of this meeting it seems like an ideal subject for the first report on this blog. I will not cover details of all the talks here; however I hope to capture the key themes and highlight a range of interesting examples from this wide ranging and high quality scientific meeting. I will also try and provide links to external sites with further information on projects/researchers where appropriate.

First blog post

January 2012.

Last year at the British Ecological Society symposium in Cambridge (Forests and Global Change) I very much enjoyed an evening talk by Ed Yong regarding science blogging and the purpose of blogging. I had always been slightly skeptical of blogs and failed to see the point of adding to the ever increasing mass of electronic ‘junk’. However, Ed got me interested… he writes the award winning blog Not Exactly Rocket Science and a great blogging advocate. The key point which grabbed my attention was that with a blog you can be now not only be “famous for 15 mins” but also “famous for 15 people”. Ed pointed out that this is particularly good news for academics who work in relatively small specialized fields so long as you are ‘famous’ for the right 15 people the blog is worthwhile. Anyway, I thought about this for some time trying to work out who might be the right 15 for me; I have outlined the my conclusions on the “Aims” page of this blog. Then I thought that the start of 2012 and the busy academic schedule for January was as good a time to start as any.

So here goes… If things go according to plan hopefully posts on Quaternary Research Association annual discussion meeting “Quaternary Science and Society” (4-6th Jan), the PAGES “Biodiversity” meeting (9-11th Jan) and Hutton Club Lecture in Edinburgh (13th Jan).
