The Atlantic Meridional Overturning Circulation (AMOC) at its weakest in more than 1 000 years

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...

Florida Current at its weakest in the past 110 years

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...

Slowdown of North Atlantic circulation caused sudden cold spells lasting hundreds of years

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....

The role of ocean circulation in sudden climate changes during the last ice age

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...

North Atlantic cooling suggests climate is about to change over much of the northern hemisphere

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...

Newly discovered Icelandic current could change climate picture

Scientists discovered new ocean current called the North Icelandic Jet (NIJ) far below the sea's surface near Iceland. It could significantly influence the ocean's response to climate change. The NIJ contributes to a key component of the Atlantic Meridional...
