Major study uncovers ‘sea change’ in world’s understanding of Atlantic conveyor belt

 

“The results highlight how important long-term data collection is to fully understanding the impact of climate change on the AMOC, says Prof Monika Rhein, an oceanographer from the Institute for Environmental Physics at Bremen University, Germany, who is also not involved in OSNAP. In a Perspectives article accompanying the new research, she writes:

‘Only long-term continuous time series can provide the much-needed benchmark to evaluate the climate model simulations. The promising results from the OSNAP array, its proximity to the Labrador Sea, and the questions raised about the processes causing AMOC variability provide excellent incentives to continue the OSNAP array for the next decades.’”

 

More time, more time.  We heard this by the US officials after obvious acid rain had killed off all living things in some Canadian lakes.  More time will not enable scientists to achieve certainty in how the Earth is affected by greenhouse gasses.

Anyway, we don’t have “more time.” There will be no benchmarks.  More and more methane is being released in the northern hemisphere and CO2 is increasing at an increasing rate and increase is variable.  Computer models will not give us reliable predictions simply because the increase in CO2 is an unknown variable.  In other words, the increases in amount vary from year to year.  The tipping point for CO2 has been reached.
