global\u202fwarming.<\/a><\/p>\nOne of the hotspots for the detection of anthropogenic carbon, and excess heat uptake is the Antarctic Ocean.<\/p>\n
How were the climate models developed?<\/h3>\n Scientists observed a region of the Antarctic Ocean, where a key mechanism called\u202f\u2019ocean subduction\u2019 was\u202fnotably located between 30\u00b0S and 55\u00b0S. This permitted the efficient transfer of anthropogenic carbon, and excess heat from the surface to the depths of the ocean, where it could be stored for centuries.<\/p>\n
Climate model projections of these carbon and heat sinks still remain highly uncertain. Reducing such uncertainties is necessary to effectively guide the development of climate mitigation policies for meeting ambitious climate targets.<\/p>\n
Bourgeois explained: \u201cClimate models have significantly improved on many aspects during the last decades, yet they still show some biases that we must reduce.<\/p>\n
\u201cModels with a more unstable water column have an efficient subduction mechanism and a strengthened carbon and heat uptake in our region of interest.\u201d<\/p>\n
What does this mean for the future?<\/h3>\n The research team discovered that models with a stable or \u2018stratified\u2019 water column revealed reduced subduction and decreased uptakes.<\/p>\n
Therefore, utilising recent statistical methodology and observational data describing today\u2019s water-column stability, the new relationship allows scientists to reduce the uncertainty of future estimates regarding the anthropogenic carbon uptake by up to 53%, and the excess heat uptake by 28%.<\/p>\n
These results emphasise that, for this region, an improved representation of the water-column stability in climate models is key to improving climate change projections.<\/p>\n","protected":false},"excerpt":{"rendered":"
A research team from The Norwegian Research Centre (NORCE) have revealed a new relationship for climate models that links both carbon and heat uptake with water-column stability in the Antarctic Ocean.
