Apparently Dennis Quaid was wrong… the gulf stream is not slowing down as some climate change models (and over the top eco-adventure movies) predict. Apparently the belief this might happen is a victim of the age old measurement error. Initial measurements suggested the slow down. It turns out over a longer period of time, there is no slow down, just an awful lot of variability from year to year. Scientists are continuing to monitor the flow in attempt to collect more data to confirm these latest findings. On top of that, they hope to figure out what causes the variability, which in and of itself is rather puzzling.
As an aside, what I find fascinating is the sheer magnitude of these sorts of issues. We’re talking attempts to understand and predict phenomena on a global scale and time scales approaching geologic time. That’s a seriously challenging task and more power to all the scientists out there trying to tackle it head on!Share:
