One the more alarming claims about global warming is that is will cause a change in ocean currents, such as the Gulf Stream.

Øystein Nordfjeld of Norway writes in with this submission:

In Norwegian media this week, professor and oceanographer Kjell Arild Orvik at Geophysical Institute , University of Bergen, confirmed their results of 20 years of measurements of the Gulf Stream. The observations have taken place outside Måløy at the west-coast of Norway, were the speed, force, and temperature have been measured every hour since 24th April 1995.

On the science web site Forskning.no he states :

What we see is that the stream is lively in the sense that it varies both seasonally and from year to year. But when observing it over 20 years, it shows long-term stability.

In the national newspaper “VG”, he emphasizes the importance of long-term observations and explains : – During the first 10 years we saw an increase in the temperature of one degree Celsius. But, during the following ten years, the temperatures dropped again and are now back to the 1995-level. This confirms the long-term variations in the Gulf Stream.
