Abstract The Palaeocene–Eocene Thermal Maximum (PETM) was a global warming event of 5–6 °C around 56 million years ago caused by input carbon into the ocean and atmosphere. Hydrothermal venting greenhouse gases produced in contact aureoles surrounding magmatic intrusions North Atlantic Igneous Province have been proposed to play key role PETM carbon-cycle perturbation, but precise timing, magnitude climatic impact such remains uncertain. Here we present seismic data results five-borehole...
Offshore solar emergence is driven by a lack of available land and the immense decarbonisation targets. It promising area photovoltaic application, with multiple benefits when co-located offshore wind, almost unlimited potential for nations living close to sea. Research understand environmental implications must be carried out in parallel realization first pilot demonstrations. Such pilots provide important opportunities learn collect field data that can used verify untested assumptions...
The intensification of the hydrological cycle, driven by global warming is expected to amplify extreme weather events and associated erosion. These shifts are likely disrupt soil stability, accelerate organic carbon mineralization, alter terrestrial ecosystems, all which have potential implications for cycle dynamics. Such feedback mechanisms remain poorly constrained. While relatively slow compared present-day change, millennial scale onset Paleocene-Eocene Thermal Maximum (PETM, ~56...
Gradual climate cooling and CO2 decline in the Miocene were recently shown not to be associated with major ice volume expansion, challenging a fundamental paradigm functioning of Antarctic cryosphere. Here, we explore ice-ocean-climate interactions by presenting multi-proxy reconstruction subtropical front migration, bottom water temperature global change, using dinoflagellate cyst biogeography, benthic foraminiferal clumped isotopes from offshore Tasmania. We report an equatorward frontal...
Abstract A Miocene phase of gradual climate cooling and CO2 decline was recently shown not to be associated with major ice volume expansion, challenging a fundamental paradigm in the functioning Antarctic cryosphere. Here, we explore ice-ocean-climate interactions by presenting multi-proxy reconstruction subtropical front (STF) migration, bottom water temperature (BWT) global change, using dinoflagellate cyst biogeography, benthic foraminiferal clumped isotopes, sea surface (SST)...
<title>Abstract</title> Variations in Earth’s orbit pace global ice-volume/sea-level changes, but the variability response for different sectors of Antarctic Ice Sheet (AIS) to orbitally-forced climate change remains unclear. We present geological records iceberg-rafted debris (IBRD) and other proxies from locations adjacent West (WAIS) East (EAIS) spanning ~3.3-2.3 Ma. Iceberg calving events WAIS recorded Ross Sea sediment cores show a linear orbital forcing at timescales corresponding...
Sediment cores from the Mid-Norwegian Margin, IODP Expedition 396 recovered several glendonite (calcite) pseudomorphs after cold-water ikaite, CaCO3&#8226;6H2O, within sediments deposited during Paleocene-Eocene Thermal Maximum hyperthermal and early Eocene greenhouse. This presents an apparent climate paradox, since this time interval, deep sea bottom water temperatures are not believed to have been lower than c. 10 &#176;C anywhere on Earth, mostly much warmer (Meckler et al., 2022...
The Paleocene-Eocene Thermal Maximum (PETM) around 56 Ma was associated with 5-6 &#176;C global warming, resulting from massive carbon release into the ocean&#8211;atmosphere system. One potential driver of hyperthermal conditions North Atlantic Igneous Province (NAIP), as both volcanic degassing and thermogenic volatile during contact metamorphism its emplacement were large emitters carbon. Despite a broad temporal correlation between NAIP activity PETM, exact relationship is...
