Dáithí is an atmospheric physicist at University of Oxford department of Atmospheric, Oceanic and Planetary Physics. The sub-department's research focuses on the study of physical processes in the atmospheres and oceans of the Earth and other planets, using experimental and theoretical techniques.

Dáithí's work focuses on examining observed changes in weather and determining if those changes do in fact reflect a changing climate and, if so, what the ultimate cause of those changes is. This involves comparing output from simulations of computer models of the climate system with the observed record.

The IPCC (Intergovernmental Panel on Climate Change) process

Dáithí contributed information to the Physical Science Basis of the IPCC's Fourth Assessment Report  earlier in 2007. He made Figure SPM-4 which examines changes in surface temperature over the past century over the six populated continents.  Notably, over all six continents the observed changes are consistent with climate model simulations including both anthropogenic (e.g. greenhouse gases) and
natural (e.g. volcanic eruptions) influences, but inconsistent with simulations that exclude the anthropogenic factors.

1. What motivates you about climate change?

Basically, I find the problem interesting.  It's at the interface between
so many different things and that mean that many fascinating issues arise.

 

2. One word (or two) on how you feel about climate change?

It's here, it's something we have to deal with in whichever way is feasible.

3. What's your vision of Oxfordshire rising to the climate challenge?

Obviously we need to think about the long term, but it seems that the
changing climate is already having noticeable effects, so the short term
matters too.  I think people should be thinking of how vulnerable they are
to the current and near-future climate, and adapt accordingly.

4. What contribution to the challenge are you most proud of?

I've been working with people here in Oxford and at the Met Office on
looking at how we can attribute changes in the risk of weather events,
such as floods and heatwaves, to human emissions of greenhouse gases. 
Ultimately this sort of information should help people to more
appropriately insure their property and, if the need arises, to seek
compensation for any damages.
