On June 12, 2010, The Institute of Atmospheric Sciences and Climate (ISAC) released "Risk of Global Climate Change By BP Oil Spill", a document detailing how the BP spill may cause irreparable damage to the Gulf Stream global climate thermoregulation activity.
"The Gulf Stream importance in the global climate thermoregulation process is well assessed", states author Gianluigi Zangari. He adds "The
latest real time satellite (Jason, Topex/Poseidon, Geosat Follow-On, ERS-2, Envisat) data maps of
May-June 2010 processed by CCAR1,2 (Colorado Center for Astrodynamics Research), checked at
Frascati Laboratories by the means of the SHT congruent calculus3 and compared with past years
data, show for the first time a direct evidence of the rapid breaking of the Loop Current, a warm
ocean current, crucial part of the Gulf Stream."
The hollywood blockbuster "The Day After Tomorrow" gives a theoretical yet very plausible consequence of thermoirregulation in ocean currents and their effect on global climate.

In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid flows past an obstacle. The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object. Fluid behind the obstacle flows into the void creating a swirl of fluid on each edge of the obstacle, followed by a short reverse flow of fluid behind the obstacle flowing upstream, toward the back of the obstacle. The release further explained that June 12th marked the point in which the eddy had detached itself completely from the mainstream therefore destroying the Loop Current as seen in the figures below.

Real time sea surface height maps (below) and sea surface velocity maps starting from april until June 12th processed by CCAR1,2 and checked at LNF (Frascati) by SHT calculus3. The star indicates the site of BP platform “Deepwater Horizon”. The yellow arrow indicates the breaking of the Loop Stream.
Radio personality Dr. Bill Deagle discusses the evidence of a break in the loop current and potential climate changes with Dr. Gianluigi Zangari.
"Couple the global temperature increases with changes in the thermoregulation of the ocean's currents could spell disaster," stated climatologist Enrico Lopez. "It's a little scary because we don't have the data to interpret this kind of event or forecasts to plot the coming climate changes," he added.
The world is enduring the hottest year on record, according to a U.S. national weather analysis, causing droughts worldwide and a concern for farmers counting on another bumper year.
Period of a El Nino weather pattern is being blamed for the hot temperatures globally, although changes in the ozone, increased ultraviolet light and increased volcanism are all wild cards in the same equation.
Abnormally warm temperatures have been registered in large parts of Canada, Africa, tropical oceans and parts of the Middle East.
Northern Thailand is struggling through the worst drought in 20 years, while Israel is in the middle of the longest and most severe drought since 1920s. In Britain, this year has been the driest since 1929.
Lopez is concerned about consistent temperature extremes, both hot and cold in the last few years. "The thing that most people don't realize is that cold is becoming a very big problem around the globe but you rarely hear about it lately outside scientific circles."
If, as the record shows, the earth has undergone a series of ice ages every 100,000 years or so like clockwork, with about 90,000 years of glaciation followed by 10,000 or 12,000 years of interglaciation, and we are now about 12,000 years since the last ice age ended, are we not overdue for another period of glaciation?
According to Bob Felix, writing in iceagenow.com:
"Research shows that there was 'a sudden and dramatic rise' in carbon dioxide in the Earth's atmosphere at the dinosaur extinction of 65 million years ago ... today's rise in CO2 levels can be attributed to our warming oceans. After all, the oceans are known as a carbon dioxide 'sink,' especially when the water is cold."
He adds: "We've forgotten that this isn't the first time our seas have warmed. Sea temperatures also shot upward 10º to 18ºF just prior to the last ice age. As the oceans warmed, evaporation increased. The excess moisture then fell to the ground as giant blizzards, giant storms and floods (Noah's Deluge type floods), and a new ice age began."
And he warns: "The same thing is happening today. Underwater volcanic activity in the Arctic Ocean [is] far stronger than anyone ever imagined!"
According to the Gosselin blog, Never has ice melted so slowly in mid summer as it has this year. Indeed sea ice melt in July 2010 is less than half the melt rate in 2007. It’s far below anything we’ve seen on record. And total global sea ice is actually positive again, despite the warm global mean temperatures.
The Neumayer III station, operated by Germany’s Alfred Wegener Institute, has recorded the lowest temperature at their Antarctic location since the start of operations there 29 years ago. The mercury dropped to -50.2°C.
Meanwhile Argentina is in an Antarctic cold snap and the Southern Hemisphere is freezing. People in Buenos Aires, for instance, are panic-buying heaters, as the mercury stays between a daytime Celsius 10 and a nighttime one.
Temperatures are also hitting record lows in Brazil. Urupema, a town in the southern Brazilian state of Santa Catarina, is experiencing the lowest temperature this year - minus 7.8 degrees Celsius. Some 20 towns and cities of the country are also suffering from unusually cold weather with temperatures falling below zero.
In New Zealand, the Mercury plunged to record lows this past month. The National Institute of Water and Atmospheric Research (Niwa) said the past few days had seen some of the lowest temperatures on record.
Other "big" changes are also making "big" headlines. NASA-funded researchers are monitoring a big event in our planet's atmosphere. The thermosphere, the layer of rarefied gases floating high above the Earth has collapsed.
Are there forces at work here that, like cosmic radiation prior to Robert Millikan's paper on the phenomenon in 1927? Like Millikan are there scientists out there who are yet to fully document all the forces in the universe that have a major effect on the Earth? And will we discover these forces in time to prepare, should this cosmic radiation have a longterm lasting effect on Earth life?
If we factor the destruction of the loop current in the Gulf into the equation, there will certainly be some unanticipated changes to global climate.
In the Gulf of Mexico, the deepest areas of warm water are associated with the Loop Current. The warm waters of the Loop Current and its associated eddies provide more energy to hurricanes and allow them to intensify.
The temperature of Gulf waters have also increased 7° higher than normal. Multiple reports have concluded the danger of this increase due to the oil and other chemicals/toxins filling the Gulf will lead to numerous changes -- not the least of which is the expectation that any storms or hurricanes developing over the region will be stalled causing them to intensify and slow down causing more destruction as they linger.
The Corexit disperant is also keeping oil submerged at deeper levels which could be a ticking time bomb when a major hurricane hits. The turbulent environment of hurricanes pulls up water from beneath the surface, often upwelling cooler water. Stronger hurricanes upwell deeper water. The oil and dispersant could then contaminate the hurricane spreading the toxins far inland .
If the water is warm at lower depths, then water being pulled to the surface remains warm, and the hurricane can increase in intensity if other atmospheric conditions are also conducive to strengthening. A continuous supply of warm water is one of several critical factors in enabling hurricanes to intensify beyond the initial level of a major hurricane (i.e. Category 3).
Comparative analysis with satellite data did not show signficant anomalies until until May 8th, 2010. Therefore it may be plausible to correlate the breaking of the Loop Current with the biochemical and
physical action of the BP Oil Spill on the Gulf Stream. It is reasonable to foresee the
breaking of a crucial warm stream as the Loop Current as a threat to stability in the thermoregulation of ocean currents. It may generate a chain reaction of
unpredictable critical phenomena and instabilities due to strong non linearities which may have
serious consequences on the dynamics of the Gulf Stream and north escalation into Atlantic waters which help regulate global climate patterns.
