Apparent Atlantic warming cycle likely an artifact of climate forcingESSC scientists Dr. Michael E. Mann and Daniel J. Brouillette and alumni scientists Dr. Byron Steinman and Sonya Miller are co-authors of a study that shows that the Atlantic Multidecadal Oscillation is not due to natural factors but, rather, due to the climate forcings of human influence and volcanic eruptions. |

Impact of climate change on New York City’s coastal flood hazard: Increasing flood heights from the preindustrial to 2300 CEDr. Andra J. Reed has published a paper with Dr. Michael Mann, Dr. Richard Alley, Dr. David Pollard, and others about the likelihood of more frequent flooding in the New York City region due to climate change and storm surge from tropical systems. |

Record Temperature Streak Bears Anthropogenic FingerprintDr. Michael E. Mann, Sonya K. Miller, Stefan Rahmstorf, Byron A. Steinman, and Martin Tingley conducted a study that proved that human caused warming likely led to the recent streak of record-breaking temperatures. |

Allowable 'carbon 'budget most likely overestimatedA recent article published in Nature Climate Change examines the definition of the "pre-industrial" baseline used for climate change discussions and projections. The group, including ESSC director Dr. Michael Mann, posits that the actual "pre-industrial" era is much earlier than the one used by the Intergovernmental Panel for Climate Change (IPCC). Changing the baseline could have an impact on targets used in agreements like the Paris Climate Accords. |
