Question
A 2023 paper by Peter and Suzanne Ditlevsen argued that this system could collapse as early as 2025, bringing about a climate tipping point. For 10 points each:
[10h] Name this system, whose interannual variation is measured by the OSNAP project. The Gulf Stream, which is part of this larger system, is responsible for the warm winters in Europe compared to North America.
ANSWER: Atlantic meridional overturning circulation [or AMOC; prompt on MOC or meridional overturning circulation; prompt on thermohaline circulation]
[10e] The collapse of the AMOC would accelerate the rate that this variable is increasing, as glaciers would melt faster. A 2023 UN report found this quantity has increased by almost 5 millimeters per year over the past decade.
ANSWER: sea level [accept sea level rise; prompt on SLR]
[10m] The data used to predict the collapse of the AMOC was from a British SST data set with this name. “Cells”named for a scientist with this name are where warm air rises at the equator before descending at 30 degrees latitude.
ANSWER: Hadley [accept Hadley Centre Sea Ice and Sea Surface Temperature data set; accept Hadley circulation or Hadley cells]
