Yes lil' climate hoax followers, the real global cooling is happening
right now!

Heinrich event ice discharge and the fate of the Atlantic Meridional
Overturning Circulation
Editorâs summary
Will ice mass loss from the Greenland Ice Sheet caused by climate
warming disrupt large-scale ocean circulation? Zhou et al. reconstructed
iceberg production rates during the massive calving episodes of the last
glacial period, called Heinrich events, when icebergs did affect ocean
circulation. The authors found that present-day Greenland Ice Sheet
calving rates are as high as during some of those events. However,
because melting is causing the Greenland Ice Sheet to recede from the
coasts of Greenland, where icebergs originate, its iceberg discharge
should not persist long enough to cause major disruption of the Atlantic
overturning circulation by itself. âJesse Smith
Abstract
During Heinrich events, great armadas of icebergs episodically flooded
the North Atlantic Ocean and weakened overturning circulation. The ice
discharges of these episodes constrain the sensitivity of overturning
circulation to iceberg melting. We reconstructed these ice discharges to
be as high as 0.13 sverdrup (Sv) (1 Sv = 1 million cubic meters per
second) during Heinrich event 4 and to average 0.029 Sv over all
episodes. The present-day Greenland Ice Sheet calving of icebergs is
comparable to that of a mid-range Heinrich event. As the future
Greenland Ice Sheet recedes from marine-terminating outlets, its iceberg
calving likely will not persist long enough for icebergs alone to cause
catastrophic disruption to the Atlantic overturning circulation,
although the accelerating Greenland runoff and continued global warming
remain threats to the circulation stability.

Recent research on the Atlantic Meridional Overturning Circulation
(AMOC) raised concern about its potential collapse through a tipping
point due to the climate-change caused increase in the freshwater input
into the North Atlantic. The predicted time window of collapse is
centered about the middle of the century and the earliest possible start
is approximately two years from now. More generally, anticipating a
tipping point at which the system transitions from one stable steady
state to another is relevant to a broad range of fields. We develop a
machine-learning approach to predicting tipping in noisy dynamical
systems with a time-varying parameter and test it on a number of systems
including the AMOC, ecological networks, an electrical power system, and
a climate model. For the AMOC, our prediction based on simulated
fingerprint data and real data of the sea surface temperature places the
time window of a potential collapse between the years 2040 and 2065.
