Summary
Aim: A key dispute in palaeoclimate research is whether or not a permanent El Niño-like state, with warm waters spreading across the equatorial Pacific, existed during the Late Miocene. Late Miocene climate was similar to the 4°C warming predicted for 2100 by the IPCC. As today’s El Niño causes global climate anomalies, a permanent El Niño-like state in the past may have had serious, global consequences, such as widespread aridity. MIONIÑO will test the existence of a late Miocene permanent El Niño-like state using geochemical microfossil records from recently recovered Western Pacific Warm Pool (WPWP) sediments to assess equatorial Pacific conditions, their driving forces and global impacts. MIONIÑO will advance past and future climate change research. Resolving the debate on permanent El Niño-like conditions in the Late Miocene will discern whether warm El Niño events will become more frequent or evolve into a new mean state. Assessing causal links between permanent El Niño-like conditions and increased continental aridity will improve the future climate models that underpin climate mitigation and adaptation strategies globally. MIONIÑO can further help us understand the true societal impact of more frequent or even permanent El Niño-like conditions.
