They say the Atlantic Ocean circulation system is weaker now than it has been for more than 1,000 years - and has changed significantly in the past 150.
The study, in the journal Nature, says it may be a response to increased melting ice and is likely to continue.
Comment: So they can't be sure what's causing it and it began 150 years ago. By most reports, ice accumulation is increasing, below the sea however, appears to be another story entirely:
- Ross ice shelf freezing, not melting as 'expected', "It blew our minds."
- Massive snow accumulation records in U.S. & Canada & Greenland all time ice gain
Researchers say that could have an impact on Atlantic ecosystems.
Scientists involved in the Atlas project - the largest study of deep Atlantic ecosystems ever undertaken - say the impact will not be of the order played out in the 2004 Hollywood blockbuster The Day After Tomorrow.
Comment: As usual the scientists involved are doing mental gymnastics to incorporate their erroneous belief of global warming with the facts they're presented with. What is clear, and surprisingly even they are able to admit it, is that the Atlantic Ocean circulation is slowing down and consequently there will be cooling, which when taken into account with data from elsewhere shows that it's a global trend, as is to be expected as we enter an ice age:
