Innovative approach can uncover low-latitude climate response to global warming
Across the Cenozoic era, spanning the past 65 million years, Earth experienced periods of extreme warmth with high greenhouse gas concentrations – similar to those projected for future climate. Understanding how low-latitude climate may respond to this warming is important due to its influence both locally and globally. At a local level, low-latitude climate affects the socio-economies of densely populated areas. Moreover, heat and moisture derived from the low-latitudes is distributed globally through oceanic-atmospheric interactions. The EU-funded ELMO project will produce the first clumped isotope-based low-latitude records of sea surface temperature and hydroclimate across the Cenozoic. An innovative approach that combines low and high-resolution methods will generate temperature reconstructions on a range of timescales, to assess the different aspects of low-latitude evolution during periods of global climate change.
