About Us

Carbon Brief is a UK-based website covering the latest developments in climate science, climate policy and energy policy. We specialise in clear, data-driven articles and graphics to help improve the understanding of climate change, both in terms of the science and the policy response. We publish a wide range of content, including science explainers, interviews, analysis and factchecks, as well as daily and weekly email summaries of newspaper and online coverage.

The team

Roz covers new research in the climate sciences and media coverage of climate change. She has a PhD in physical oceanography from the University of Southampton and previously worked in the science communication unit at the University of the West of England, Bristol.

Simon Evans   Dr Simon Evans (@DrSimEvans) is our policy editor.
Simon covers climate and energy policy. He holds a PhD in biochemistry from Bristol University and previously studied chemistry at Oxford University. He worked for environment journal The ENDS Report for six years, covering topics including climate science and air pollution.

Sophie Yeo   Sophie Yeo (@some_yeo) covers climate and energy policy.
Sophie holds an MA in journalism from Cardiff University and studied English literature at Oxford University. She previously spent two years at Climate Home, writing about the UN climate negotiations and international policy.

robert-mcsweeney-bio-pic   Robert McSweeney (@rtmcswee) covers climate science.
Robert holds an MEng in mechanical engineering from the University of Warwick and an MSc in climate change from the University of East Anglia. He previously spent eight years working on climate change projects at the consultancy firm Atkins.

ros-author-bio-pic   Rosamund Pearce (@_rospearce) is our multimedia journalist.
Ros focuses on infographics, video and social media. Rosamund completed an MSc in science communication from Imperial College London in 2014. She has previous experience working for the Science Museum and the Wellcome Trust.

polly-bennett-bio-pic   Polly Bennett (@digitalpolly) is our digital content manager.
Polly holds a BSc in biology from the University of Southampton and a MSc in science communication from Imperial College London. She has spent several years working in digital communications and marketing for charity and academic organisations, such as CERN and King’s College London.


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.
