The interactive page also says : "Whether it will collapse can not be stated 
with certainty ...but... Due to the potentially serious impact on our 
climate of a collapse of the THC, it must be regarded as a LOW RISK, high 
impact event that can not be ignored."

Do I notice belief in the power of positive thinking here? Also, this model 
was made pre BP interference in the Gulf. And that air circulation will 
partly take over from oceanic currents is something I have long been afraid 
off. In New Zealand they are suffering from winds between 130 and 160 km/hr 
these days at times. Few of our shelter belts would survive this with our 
shallow soils and we have seen serious wind damage to buildings here with 
winds of just 120 km/hr.
We can only hope for the best (and try to prepare for the worst).
