Here I chat about a new study looking at essentially all the marine terminating glaciers in Greenland and how submarine (underwater) melting rates are not only dependent on ocean warming amounts, but are also highly dependent on Greenland surface melt, forming meltwater ponds that drain via fractures and crevices and moulins in the ice sheet to the bottom of the glacier, where the meltwater combines with friction melted water to exit the glacier at the bottom between the ice and bedrock. Once exiting, this cold fresh water (lower density than warmer salty ocean water) rises in plumes, causing turbulent flow next to the edge of the ice/water interface greatly increasing underwater ice melting rates.

My country is a water- stressed country so any changes that amplifies warming will have a knock-on effect on our meagre water budget (and water security) & hence food security (country's poverty rate is high to more expensive food will be catastrophic). Most climate change news focuses on the northern hemisphere, so any videos on the impacts of climate change down south will be most welcome.

There are other things that are being triggered into action by what WE are doing. Such as, cutting down trees and then making IMPOSSIBLE for them to come back. Meanwhile continuing to retrieve carbon based chemicals from deep underground, that we use as fuel and CONTINUALLY are "dumping it" (garbage) into the air. We are modifying the "formula" of the atmosphere. That's just a SMALL PART of what we've gone and done.

Merci beaucoup Paul. I wonder if the basal warm water layer has anything to do with the 1000 hPa heat dome observed over Greenland? There have been days in October that an extensive part of Greenland had a temperature approaching 10°C in October. There had been a couple of years going back to 2015 where there was such a heat, but never as extensive and never as late as this year. Using NASA Worldview, it is scary to see all the pre-Moulin melt ponds pockmarking Greenland's glaciers. Why don't you COPOUT this year, Paul? The only COP that was necessary was COP 1, where they said we had 10 years to stop burning fossil fuels. And that was before the MASSIVE push to fracking and tar sands in 2005. It puts into perspective my efforts from 20 years ago to try to implement Windyday Concept. And WTH haven't you ever said anything about WDC in your videos with Regina and Peter?

Good. Are there any scientific projections on how a late -2023 El Niño might affect (amplify ?) these dual melting effects on Greenland? Speculating on the way that climate change is accelerating, maybe we could have a "Super" El Niño event, inducing possibly previously unseen dynamic effects upon the Arctic? If such persisted into late-2024 the limits of uncharted territory would surely be severely tested even further. Its staggering how corporate greed's neglect of environmental consequences has brought us to this precarious situation.

@kimweaver1252 2 жыл бұрын

Ice absorbs about 79cal. per gram which undergoes phase change. So, yes, ice is keeping us cool. That is one reason why the atmospheric heating will rapidly increase as the amount of ice diminishes. It is going to be heating much more rapidly and the faster the change, the more species we lose.

Question: is the root cause of the warming and climate changes geological? A destabilized core along with magma intrusion towards the surface. This explains why we see melting in west antarctica but not in east antarctica. This intrusion began in 1995. This is also occurring under greenland and Siberia, evidence suggests. Explains the increasing earthquakes and volcanic activity also. A 12 thousandish year cycle, maybe.

That is correct, the magnetic excursion. Outer core expansion = increased pressure and heat under the crust. First evident under the thinnest crustal regions of the ocean plates. I believe the count of submarine volcanos under west Antarctica is 200. Greenland is a geological hot spot. As for Siberia ( and Canada ), the magnetic field is weakest over these areas, allowing increased UV radiations

Topographic maps of Greenland with the center of Greenland being lower than sea level. Pondering if over a great time could this be from compression of the surface by the weight of the ice? After both poles melt and today there is a great variability to how long this might take. Would it be in 20-30 years or at the end of the century? Better to predict somewhere between but for sure there will be other great complications well before and after.

@@philipm3173 Yes, that is correct. But more than than, Fluid Magmatic superplumes that are laid by Continental Icesheets as they build up, rifting the crust, and pumping at 1400psi pressure per kilometre of above sea level altitude down through the crust, and deep into the mantle. What you have with Northern hemisphere Heinrich-Bond-Dansgaard-Oeschger cycles is a seesaw process, where the icesheets build up, start pumping Magma and hot geofluids, destabilising the margins with cascade fringe icecliff failure setting in, which depressurised the aquifer, triggering runaway magma and geofluid heating as Hydroxl and protons, and other light elements in ionic fluid state, recombine as they are crashed through supercritical phase change pressure boundaries. Heat of formation of H2O from hydroxl and protons is 57 megajoules per kg. So a continental ice sheet is capable of storing as a chemical battery, enough thermal energy to evaporate all the earth's Oceans. Fortunately what happens is that they operate in a binge-purge fashion, initiating pulse tectonic effects. The last major activation of this system was the younger Dryas, when the volcanically heated water in the Greenland sea and Arctic Basin evaporated so much steam that it caused ferocious winter snowfalls in western Europe and North America, too much to melt in summer, causing western Europe and Eastern North American average July temperatures to crash by 25C in ONE YEAR! This lasted for about a thousand years, until The mid lattitude icesheets destabilised, initiating the Holocene Greenland glaciation. There was a lesser scale event at the 8200 years before present Holocene thermal maximum termination, thought by many to be the Noah's flood event. The Egyptian and many other ancient cultural libraries record three such global Oceanic Transient Thermal Expansion highstands in the last 20000 years, the Noah's Flood event being the most recent.

Hey Paul, Just fact checking a couple of things, Assuming you are aware that both poles are now situated out in the ocean, as they head towards the dragon & Bermuda triangles respectively. (cyclic pole flip, you know this right?) I am sure you can understand the weakening mag filed is only going to get worse? I am hoping that you understand the connection between the suns mag field and our own and how the sun plays major roles in our weather etc. I am hoping i have not lost you, this is basic 101 fundamental space science, how we are all connected. As the poles move around, maybe only approx 10yrs before they fully shift, the weather changes accordingly. The planet actually goes into mass stress & is electromagnetically exposed to the coronal mass ejections much more while the field is recovering (this'll take decades, after all, this has been happening since the 1800's) all common facts. I can guarantee you that IF there was anything us puny little people could do to fend off any cyclic change & the effects our closest star has on us, well, that bus (if it ever existed) has surely left the building. If you know these basic facts & the highly agreed on results of these things, why do you continue to waffle on and enable the govt to reach into our pockets to tax us for the damage we are NOT doing? I hope you are receiving a financial kickback for this, if not, you may want to revisit what you are trying to achieve here.
