Thomas Frölicher

Ph.D., Climate & Environmental Physics

2012-2013, 2014-2015 Senior Research Fellow (Princeton University)

Assistant Professor, University of Bern

Thomas Frölicher’s research involves consideration of models, theory, and observations. He is interested in the present and future climate and carbon cycle interaction from a regional to global scale. His research focuses on the ocean components of the Earth System and its role in nutrient and carbon cycling and ultimately climate. He is also interested in exploring the responses of ecosystems and fisheries production to past and future climate variability and change. Frölicher was a senior scientist at ETH Zurich and is now working as an Assistant Professor at the University of Bern.

At the 4th International Symposium on the Effects of Climate Change on the World’s Oceans from June 4 to 8 at the Washingington Hilton, Nereus Program Principal Investigator Thomas Frölicher (Princeton; University of Bern) and Nereus Fellow Gabriel Reygondeau (UBC) will be hosting a session about extreme ocean events and their impacts on marine ecosystems.

Nereus director (science) William Cheung (UBC) and Thomas Frölicher (University of Bern) are co-authors on the newly released Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) Summary for Policymakers (SPM). It was approved and presented at the Intergovernmental Panel on Climate Change (IPCC) on September 25, 2019.

Thomas Frölicher is a co-author on a new open access paper published in Nature, “Global vulnerability of marine mammals to global warming”. You can read a short summary and access it here.

Principal investigator Thomas Frölicher is a co-author on an open access study recently published in Biogeosciences, entitled “Is deoxygenation detectable before warming in the thermocline?”

William Cheung and Thomas Frölicher recently published a study in Nature Scientific Reports showing the impact marine heatwaves have on fish stock biogeography and biomass in the northeastern Pacific Ocean.

Thomas Frölicher is co-author with a team of researchers on a study analyzing the impact that ceasing atmospheric CO2 emissions could have on global warming. They show that within five decades, temperature increases become essentially zero if emissions are kept within the global human “carbon budget” set within the IPCC AR5.
