The discovery of new evidence about the behavior of the Gulf Stream during the last ice age could mean that it is more sensitive to future climate change than previously thought. Study published in journal Nature and led by researchers from University College London (UCL) found that around 20,000 years ago, an exceptionally strong Gulf Stream was associated with more intense winds over the subtropical North Atlantic. This finding suggests that a slowdown in such winds, as some studies have predicted could occur under ongoing climate change, would actually sap energy from the Gulf Stream, with potential consequences for heat distribution, sea level.
