The Weather Channel is hyping a report in the journal Nature that suggests the Gulf Stream is the slowest it has been in 1600 years. If you go to the link, you can see the anchor's video report on the study. What you will not see is that in the article the Weather Channel notes another study in the same journal says the slow down in the last 150 years has not been caused by man made global warming.
A separate study, also released Wednesday in the journal Nature, claims the 150-year slowdown of the AMOC is a result of natural changes, not man-made climate change. But both conclude the slowdown is occurring, and it could impact our weather in the coming years.
The Weather Channel focused on the former study and not the later story on its televised report and only threw in at the end that some scientists are skeptical because of a lack of data. "MIT professor Carl Wunsch said the study's 'assertions of weakening are conceivable, but unsupported by any data' in an interview with the AP." Not the "by any data."
We have gotten to the point of religious assertion in the global warming debate when scientists, without any data and credible conflicting studies, can declare that 1600 years ago the Gulf Stream was slower than it is now, but the current slowdown is the result of man made global warming.
Scientists from 1600 years ago were unavailable for comment.
