Is the thermohaline circulation really at risk? This short movie tells...

This is a short movie on the research and results of the THOR researchers.

The movie is available here

Is the thermohaline circulation really at risk? from THOR Project on Vimeo.

But what did we actually find out in 4 years of researches?

The Gulf Strom is more stable than expected, an ice age is unlikely to happen.

The closing event of the project presented the results of 4 years of researches.

Here is what journalists reported:

Did you know that the thickest parts of Arctic Ice Cap are melting faster?

"A new NASA study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean’s floating ice cap."

What is the THC and why should we worry if this might be at risk?

The intervention in three parts of Bogi Hansen (HAV) at the TACC in early April 2008 marks the origin of the THOR project back in 2008, when the proposal had just been approved. The three Youtube videos explain the concerns of the scientists working for the THOR project, and the starting point of their researches and investigations. Each part lasts approx. 9 minutes.

 The TransAtlantic Climate Conference 2008 (TACC 2008) held in the Nordic
House on the Faroe Islands on 7 – 8 April 2008 with participation of more than 300 people from the Faroe Islands and abroad.
The Goal of the conference were:
• Bring into focus climate changes in the Atlantic Ocean
• Identify challenges related to an improved ocean climate
• Showcase opportunities for a “Trans Atlantic Climate Institute” (TACIT)
• Conduct workshops on relevant topics in this relation

A compendium pf the TACC 2008 can be found here:

Ice sheet climate system interaction in a warming world

"Results of an anthropogenic climate change experiment are highlighted in the following movie, where the atmospheric CO2 concentration raises by 1% per year until a concentration of  4xCO2 is reached. Afterwards the concentration stays constant. As a consequence of the CO2 forcing, the convection depth decreases in time (upper left legend) in particular in southern Labrador Sea in the northern GIN Sea. Also summer sea ice cover (lower right legend: light and dark blue) retreats and is gone at around year 2100. Afterwards, the winter sea ice also strongly decreases until even the winter sea ice is history (2200)."

Thermohaline circulation using improved flow field

Videos and images related to the thermohaline circulation provided by NASA/Goddard Space Flight Center Scientific Visualization Studio

This version of the visualization combines the Earth look of the original thermohaline visualization with the new thermohaline flow field generated for the Science on a Sphere production, "Loop".


NASA: films and images on perpetual Oceans

This visualization shows ocean surface currents around the world during the period from June 2005 through Decmeber 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.This visualization was produced using NASA/JPL's computational model called Estimating the Circulation and Climate of the Ocean, Phase II or ECCO2. ECCO2 is high resolution model of the global ocean and sea-ice. ECCO2 attempts to model the oceans and sea ice to increasingly accurate resolutions that begin to resolve ocean eddies and other narrow-current systems which transport heat and carbon in the oceans.The ECCO2 model simulates ocean flows at all depths, but only surface flows are used in this visualization. The dark patterns under the ocean represent the undersea bathymetry.
