Slowdown of Atlantic overturning circulation caused by changes in southern hemisphere

According to the newest study, conducted by the scientists from the University of Washington, the Atlantic overturning circulation, responsible for mild climate conditions over England, is currently slowing down, a shift likely to have consequences for the climates...

Tropopause cooling a part of natural decadal cycle

The cooling trend observed in the late 20th century at the transition between the troposphere and stratosphere at an altitude of about 15 kilometers is usually believed to be caused by human influences. Now, climate scientists from Kiel And Bergen (Norway) have...

Ice melting 10 000 years ago caused radical climate shift in Europe and Africa

A team of researchers led by the Ruhr-Universität Bochum investigated how the meltwater from the ice sheet in North America produced a massive impact on climate conditions in northwest Europe and northwest Africa by the end of the most recent ice age, about 10...

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...

Whistling wormholes of the Caribbean

A team of scientists led by Professor Chris Hughes (University of Liverpool, NOC) analyzed the Caribbean Sea levels and pressure readings taken from the bottom of the sea and noticed a new phenomenon which they have called a 'Rossby whistle.' The team has...

A Sea of Charge: Oceanic microstructures

Seawater is not very exciting when you look at it. It is, presumably, just water with salt and other minerals. To most of the denizens of Earth’s oceans, the sea is something quite different, a web of gel. According to an article from New Scientist magazine,...

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...

Study suggests Gulf Stream weakening associated with a recovery from earlier strengthening

The Atlantic Meridional Overturning Circulation (AMOC), part of which is known as the Gulf Stream, has been seen weakening over the past decade. Although this weakening trend raised questions whether it has been caused by climate change, a new research suggests this...

Significant rise of the cephalopods in the world's oceans observed over the last 60 years

A new international research, led by the scientists from the University of Adelaide, South Australia, suggests that contrary to the fish species, the number of cephalopods (octopus, cuttlefish, and squid) in the world's oceans, have increased over the last 60...

Unprecedented toxic red algal bloom severely impacts Los Lagos, Chile

The southern area of Los Lagos, Chile, has been affected by the unprecedented red algal bloom over the last month. The phenomenon has caused thousands of local fishermen to protest the government's "insufficient" effort to alleviate the economic...

Previously unknown, massive source of methanol identified

A team of scientists from the Woods Hole Oceanographic Institution (WHOI) have identified the massive, previously unknown source of methanol in the ocean. According to the study, the phytoplankton, microscopic plant-like organisms, possess a surprising and unique...

Greenland 'Warm Blob' surface water responsible for abrupt climate swings in the last ice age

New research shows a "warm blob" of surface water in the Atlantic played a significant role on the wild climate swings in Greenland during the last ice age. Researchers used the foraminifera fossils to compare the changes in the ocean temperature with the...

Rapid plankton growth in North Atlantic suggests a swift environmental change

An unusual plankton growth has been discovered in the North Atlantic, in contrast to the scientific predictions for the area. The discovery suggests a swift environmental change as a result of increased amounts of carbon dioxide may be underway. A team of...
