A new study by an international research team found that the Atlantic Meridional Overturning Circulation (AMOC) has remained stable since 1963, contradicting previous claims of a long-term weakening trend.
Recent research on the Dansgaard-Oeschger event provides a better understanding of climate tipping points during the last Ice Age. The researchers used multiple ice cores collected across Greenland with data spanning up to 120 000 years, providing a new understanding of these abrupt events, how they unfold, and what that might mean for the future. It is really important to understand such tipping points in the climate, because they may result in catastrophic and irreversible change, the lead author of the study said.
A recent study led by Dipanjan Dey of the University of Southampton, in collaboration with international scientists, revealed the vital role that Atlantic and Arctic water mixing plays in maintaining the Atlantic Meridional Overturning Circulation (AMOC), an essential component of the global climate system.
Scientists from the National Centers for Environmental Information (NCEI) and the University of Maryland have provided evidence of a significant slowdown in the Atlantic Meridional Overturning Circulation (AMOC), a key climate regulator. Published in Frontiers in Marine Science, the research utilized over six decades of oceanic data to track the health of this vital oceanic component. This slowdown, observed primarily in the last two decades, could have profound implications on global climate patterns.
A new study published in Science Advances by René M. Van Westen, Michael Kliphuis, and Henk A. Dijkstra on February 9, 2024, unveils a physics-based early warning signal indicating the Atlantic Meridional Overturning Circulation (AMOC) is on a tipping course towards collapse.
The Atlantic Meridional Overturning Circulation (AMOC), one of the Earth’s major ocean circulation systems that underpins the Gulf Stream, is now at the weakest it has been in more than 1 000 years, a new study shows. Models suggest that this could trigger…
New research by the Woods Hole Oceanographic Institution (WHOI) found that a key component of the Gulf Stream– a warm Atlantic ocean current stretching to the tip of Florida– has steadily slowed and is now weaker than at any other point in the past 110 years. The…
A new study from the University of Helsinki in Finland reports that sudden cold spells lasting hundreds of years took place in the middle of the warm Eemian climate period, about 120 000 years ago, as a result of the slowdown of the North Atlantic circulation….
Ice cores from Greenland and Antarctica show that there was a period during the last ice age, when our planet experienced dozens of abrupt temperature shifts. Plummeting and rising again every 1500 years or so, those sudden temperature shifts wreaked havoc on the…
Based on the observations of ocean heat content in the North Atlantic Ocean, the climate in the northern hemisphere is on the verge of a change that could last for several decades. This change is associated with the Atlantic Multidecadal Oscillation (AMO)1 – a mode…
