I came across some more oddities in this game of Climate Change and how scammy it is. Lets look at some information about this ice age, or more literally a re-glacialization.
In the Video from "In Search of" some data points were discussed, one of these was the importance of Glaciers on Baffin Island Canada.

So we have multiple points of research stating that a slowing down of the Atlantic meridional overturning circulation can drop the global temperatures enough to force a glacial period to begin. We also have research that points to a slowing of Glacial movements caused by global temperatures but the melting of these glaciers is still taking place but during times of slowed glacial melt the fresh water is retained or stored in the glaciers. When these reserves of fresh water reaches a certain pint, that fresh water will dump into the Atlantic Ocean, and this action can stop the AMOC from functioning for a very long period of time.
Now with this ice age looming over our collective heads, why are politicians so intent on limiting public information about this? It's because warmer summers due to the oceans not being able to recycle that heat is easier to explain away as "Global Warming" than it is in educating the public on the inevitable cold period that we should be preparing for. Encouraging the public false impression of this global warming means that it's easier to fleece the public for money.
I'll post more as I come across it, but it's a very difficult topic to dig for since getting information that hasn't been tainted by the Trillion Dollar CIC (Climate Industrial Complex) is becoming harder and harder to get.

Quote:AbstractThe North Atlantic was a key locus for circulation-driven abrupt climate change in the past and could play a similar role in the future.
From the report,
Quote: The climate system is capable of abrupt changes when a threshold is crossed that shifts the climate system into a different state (National Research Council, 2002). Because of the potential for abrupt change in the near future (e.g., Lenton, 2011)—and the heightened societal vulnerability to rapid rates of climate change—examples of abrupt climate change in the paleorecord are particularly important to understand (Alley et al., 2003; Broecker, 2000). The sudden reduction or shutdown of Atlantic Meridional Overturning Circulation (AMOC), which is responsible for the transport of low-latitude heat to the Arctic, is a known mechanism for abrupt climate change (Broecker, 1991; Clark et al., 2002; Sgubin et al., 2017). A sudden influx of freshwater in key downwelling sites (e.g., the Labrador Sea) can effectively slow or shut down AMOC, reducing latitudinal heat transport and thus promoting high-latitude cooling.

Warning of a forthcoming collapse of the Atlantic meridional overturning circulation | Nature Communications
Quote: A forthcoming collapse of the Atlantic meridional overturning circulation (AMOC) is a major concern as it is one of the most important tipping elements in Earth’s climate system[sup]1,2,3[/sup]. In recent years, model studies and paleoclimatic reconstructions indicate that the strongest abrupt climate fluctuations, the Dansgaard-Oeschger events[sup]4[/sup], are connected to the bimodal nature of the AMOC[sup]5,6[/sup]. Numerous climate model studies show a hysteresis behavior, where changing a control parameter, typically the freshwater input into the Northern Atlantic, makes the AMOC bifurcate through a set of co-dimension one saddle-node bifurcations[sup]7,8,9[/sup]. State-of-the-art Earth-system models can reproduce such a scenario, but the inter-model spread is large and the critical threshold is poorly constrained[sup]10,11[/sup]. Based on the CMIP5 generation of models, the AR6 IPCC report quotes a collapse in the 21st century to be very unlikely (medium confidence)[sup]12[/sup]. Among CMIP6 models, there is a larger spread in the AMOC response to warming scenarios, thus an increased uncertainty in the assessment of a future collapse[sup]13[/sup]. There are, however, model biases toward overestimated stability of the AMOC, both from tuning to the historic climate record[sup]14[/sup], poor representation of the deep water formation[sup]15[/sup], salinity and glacial runoff[sup]16[/sup].
The most important part to remember here in this report is this:
Quote: The AMOC has only been monitored continuously since 2004 through combined measurements from moored instruments, induced electrical currents in submarine cables and satellite surface measurements. Over the period 2004–2012, a decline in the AMOC has been observed, but longer records are necessary to assess the significance. For that, careful fingerprinting techniques have been applied to longer records of sea surface temperature (SST), which, backed by a survey of a large ensemble of climate model simulations, have found the SST in the Subpolar gyre (SG) region of the North Atlantic (area marked with a black contour in Fig. 1a) to contain an optimal fingerprint of the strength of the AMOC.

Quote: Anomalously high summer temperatures over the last few decades have resulted in sharply increased mass losses of glaciers and ice caps in the Canadian Arctic Archipelago (CAA), particularly since 2005 (Gardner and others, Reference Gardner2011; Harig and Simons, Reference Harig and Simons2016). Between 2003 and 2009, glaciers and ice caps of Baffin and Bylot Islands in the southern CAA lost mass at an area-averaged rate 1.6 times greater than glaciers in the northern CAA (Gardner and others, Reference Gardner, Moholdt, Arendt and Wouters2012). Projections by a coupled atmosphere/snow model forced with the IPCC's moderate RCP4.5 greenhouse gas emission scenario forecast sustained and irreversible glacier mass losses in the CAA, increasing from −51 ± 26 Gt a[sup]−1[/sup] over the period 2000–11 to −144 ± 33 Gt a[sup]−1[/sup] by the end of the 21st century, resulting in a projected 18% loss of the current ice volume (Lenaerts and others, Reference Lenaerts2013).
A major unresolved question in assessing the response of Arctic glaciers to climate change is whether they will speed up or slow down as surface melt rates increase. Observations of short-term, high velocity events on some parts of the Greenland ice sheet (GIS) in summer (Zwally and others, Reference Zwally2002) have led to concerns that accelerated ice motion may occur as the climate warms and surface melt rates increase. In turn, this could produce dynamic thinning (Alley and others, Reference Alley, Clark, Huybrechts and Joughin2005) and greater drawdown of ice from the interior, resulting in increasing mass wasting rates in response to future warming (Parizek and Alley, Reference Parizek and Alley2004). Several studies support the short-term speedup mechanism initially proposed by Zwally and others (Reference Zwally2002), in that delivery of surface meltwater to the ice-sheet bed results in an over-pressurized basal drainage network, reduced basal friction and a short-term increase in ice motion. For example, Bartholomew and others (Reference Bartholomew2012) measured pronounced multiday speedup events inferred to be forced by rapid variations in meltwater input to the subglacial system from diurnal and weather-related fluctuations. Similarly, Fitzpatrick and others (Reference Fitzpatrick2013) measured a dramatic acceleration (100% over 11 days) on the lower portion of an outlet glacier, located on the western sector of the GIS, 4 days after the onset of melt. Similar positive relationships between melt and short-term velocity variations have been observed on temperate and polythermal valley glaciers (Iken, Reference Iken1981; Mair and others, Reference Mair2003; Copland and others, Reference Copland, Sharp, Nienow and Bingham2003b) .
However, other recent studies indicate that the relationship between increased surface melt rates and glacier velocities is not straightforward. For example, Sundal and others (Reference Sundal2011) found a positive correlation between surface melt rates and peak velocities during early summer (~May to mid-July) for land-terminating glaciers in southwestern Greenland over a 5 year period, but found that mean summer velocity was lower during high melt years. A slow-down occurred when a critical amount of meltwater entered the ice sheet, causing a switch to a channelized subglacial drainage network. In years with high surface melting this switch occurred earlier in the summer, resulting in lower mean summer ice velocities compared with years with less melt. Simulations using subglacial hydrology models support this pattern as they show that when the subglacial water inputs exceed a critical rate, subglacial channelization occurs rapidly (Schoof, Reference Schoof2010; Banwell and others, Reference Banwell, Hewitt, Willis and Arnold2016). Other studies have identified a relationship between high summer melt rates and the evolution of a more efficient subglacial drainage system, which results in lower velocities the following winter (Burgess and others, Reference Burgess, Larsen and Forster2013; Sole and others, Reference Sole2013; Tedstone and others, Reference Tedstone2013). Long-term (≥8 years) ice motion measurements from a land-terminating region of the western GIS (Tedstone and others, Reference Tedstone2015) and many other non-surging glaciers elsewhere (van de Wal and others, Reference van de Wal2008; Heid and Kääb, Reference Heid and Kääb2012b; Waechter and others, Reference Waechter, Copland and Herdes2015; Thomson and Copland, Reference Thomson and Copland2017) also reveal decreasing ice velocities despite an overall increase in temperature and surface melt rates.
So we have multiple points of research stating that a slowing down of the Atlantic meridional overturning circulation can drop the global temperatures enough to force a glacial period to begin. We also have research that points to a slowing of Glacial movements caused by global temperatures but the melting of these glaciers is still taking place but during times of slowed glacial melt the fresh water is retained or stored in the glaciers. When these reserves of fresh water reaches a certain pint, that fresh water will dump into the Atlantic Ocean, and this action can stop the AMOC from functioning for a very long period of time.
Now with this ice age looming over our collective heads, why are politicians so intent on limiting public information about this? It's because warmer summers due to the oceans not being able to recycle that heat is easier to explain away as "Global Warming" than it is in educating the public on the inevitable cold period that we should be preparing for. Encouraging the public false impression of this global warming means that it's easier to fleece the public for money.
