Contributing editors

Our editorial team is kindly supported by a handful of UK-based scientists, each specialising in various areas of climate science. As contributing editors, they help to keep us up-to-date with the latest scientific developments, as well as advising us, when required, on matters of scientific accuracy. Our contributing editors are not paid by Carbon Brief and do not endorse our content.

Richard Allan Richard Allan (@rpallanuk)
Richard is a
professor of climate science at the department of meteorology, part of the University of Reading with affiliation to the National Centre for Atmospheric Science, the National Centre for Earth Observation and the Walker Institute. His research focuses on how much the Earth will warm in the current century and what the implications might be for the global water cycle. He is the principal investigator on the Natural Environment Research Council’s DEEP-C project (Diagnosing Earth’s Energy Pathways in the Climate system).

Mark Brandon Mark Brandon (@icey_mark)
Mark is
reader in polar oceanography at the Open University’s department of environment, earth and ecosystems. His research interests are Antarctic polar oceanography and he specialises in the use of robotic and remote sensing technologies. In 2012, he won the Times Higher Education Award for “Most Innovative Teacher of the Year”. He was the principal academic advisor on BBC’s Frozen Planet series.

95-piers-forster Piers Forster (@piersforster)
Piers is
professor of physical climate change at the University of Leeds, where he has been since 2005. He studied physics at Imperial College and gained a PhD in meteorology from the University of Reading in 1994. He spent part of his research career working at NOAA in Boulder, Colorado. His expertise is in quantifying the causes of climate change and how the climate responds. He is currently researching geoengineering methods and decadal variability. Piers was a lead author on both the AR5 and AR4 IPCC assessment reports.

95-gabriele-hegerl Gabriele Hegerl
Gabriele is
professor of climate system science at the School of Geosciences at the University of Edinburgh, where she has been since 2007. Her research focuses on variability and change in climatic extremes and precipitation, estimating climate sensitivity, and the use of palaeo proxy data to study climate variability and change during the last millennium. She was a member of the core writing team for the IPCC’s AR5 synthesis report. She has been the chair of the scientific review group of the UK’s Met Office Hadley Centre since 2014.

Simon Lewis Simon Lewis (@simonllewis)
Simon is
professor in global change science at University College London. He holds an equivalent position at the University of Leeds. He was a Royal Society university research fellow (2004-2013), and in 2011 received a Philip Leverhulme Prize recognising the international impact of his research. In 2014, he was listed as one of the world’s most highly cited scientists in the environment/ecology field. Simon is a plant ecologist by training with a central focus on the tropics and global environmental change, including climate change. His primary interest is in how humans are changing the Earth as a system.

Tim Osborn Tim Osborn (@TimOsbornClim)
Tim is a
professor of climate science at the Climatic Research Unit, within the School of Environmental Sciences at the University of East Anglia, where he has worked since 1990. His research focuses on identifying variations in climate – observed, modelled and recorded in climate proxies – and understanding their causes, both natural and anthropogenic climate processes. He was a lead author on IPCC AR5, contributing to the chapters concerned with palaeoclimatic information and with the detection and attribution of climate change.

95-camille-parmesan Camille Parmesan
Camille is a
professor in the Marine Institute at Plymouth University where she holds the National Aquarium chair in the public understanding of oceans and human health. She is also an adjunct professor in the department of geology and a senior research fellow in the Environmental Science Institute at the University of Texas at Austin. Her research focuses on the biological impacts of anthropogenic climate change in natural systems and she is one of the world’s most highly cited academics in the field of climate change. She has been involved with the IPCC for more than 15 years.

Peter Stott Peter Stott (@StottPeter)
Peter is the
scientific strategic head for the climate monitoring and attribution at the Met Office Hadley Centre. He leads a team of 30 scientists involved in the development of the observational evidence base for responding to climate variability and change. The group is responsible for developing observational data sets, including the HadCRUT global surface temperature series and for undertaking research into the causes of climate change. He was coordinating lead author for Chapter 10 (Detection and attribution of climate change: from global to regional) of the Working Group 1 of IPCC AR5.
