I am grateful for your research. Where was the plate Greenland is on in the holoscene? I seem to remember a time when Norwegian settlers lived in Greenland. They even named it GREENland. The weather changed, and all starved to death when cold took over. Norwegians named Iceland to keep settlers away. I am NOT convinced man can do a thing to change the climate. It's bigger than anything piddly man can do.

It’s OK if you’re not convinced. Lessons, keep repeating themselves until learned. You need to understand that CO2 is a greenhouse gas, understand the significance of the keeling curve(you can look that up) how ice extent affects the reflectance of the suns energy(albedo), that 90% of the energy that makes it to earth is absorbed by the oceans. After you have that nailed read.” storms of my grandchildren.” by James Hansen. It’s from 2008, but the science is the same. Climate science is pretty important to the near term Survival of our democracy. If you don’t understand it, you probably shouldn’t vote because you won’t know who is lying to you.

Thank you for a great talk! The claim that I keep hearing repeated over and over is that it's currently hotter than it's been in the past 100k years, but you very clearly show evidence of the Arctic being 3-4C warmer just 10k years ago. Would you consider today's warming/melting to be alarming when just 5-6k years ago, most of the sampled glaciers were either smaller or non-existent compared to today?

@personzorz

Ай бұрын

It is important to note that the reasons for the Arctic being hotter are different. In the early Holocene it was because of oscillations in the Earth's orbit causing there to be more total sunlight to the Arctic specifically during summer. Now it is due to the changes in atmospheric composition causing a global increase in total thermal energy. The work indicated here indicates what will happen to the Arctic as it warms, but not the rest of the world.

@307alexk

​@@personzorz For sure, but it seems like a good portion of the alarm is coming from the idea of Greenland melting and dumping tons of freshwater into the ocean, causing catastrophic sea level rise and potentially tipping the AMOC into turning off. But this study contradicts that alarmist point of view - we know that sea level rise has been relatively stable for the past 5k years, even with a melting arctic.

@@307alexk I think you'd need to ask the presenter about the altitude of the ice sheet surface. The higher temperature readings were coming from ground level lakes, while a lot of the melting would be coming from the surface of the ice sheet which used to be higher. I naively would think that that would make modern temperatures like the early Holocene lead to more melt, but it's not my work.

Not last time I checked. Ice melt models are still in their infancy. There's a lot of work to be done in that area. I'm trying to think of a glaciologist that would know... perhaps Jason Box. I know he did lots of observations/measurements on dark now on Greenland and once heard him critic models on that topic.

The idea that it’s not warm enough to cause the ice melt is kinda missing the point. It’s a debate against precision versus accuracy. Obviously it’s warm enough to heat the ocean somewhere to bring this warm water to melt this ice. Being precise about the local air not being warm enough is inconsequential and beating a dead horse. How does this information change the outcome?

Totally missing the point. Ice sheets are geothermal heat traps, and pressure caps that pump water at up to 6000psi above sea-level pressure down into the litho sphere, where it is solvated as ionic fluids in the mantle. Storing 57 mega joules per kg of that trapped geothermal heat as hydroxyl and protons in low temperature melts. Albite as one example, fully miscible with hydrous fluids from 10 to 20 km down, and above 600 degrees. When the geothermal borecap starts to rupture ate the fringes, in the fracture rifts of ice streams, the pressure drop releases that thousands of years of stored chemical energy as thermal energy, and an exponential runaway melt, blowup of the ice dome commences. That's why hot water is blowing out from under all the major ice streams of Greenland and Antarctica. This also initiates a pulse of spreading ridge volcanism, like you are seeing in Iceland, and subduction, as the sudden isostatic uplift occurs at the continental ice sheet fringes. Warmer sea and Air temperatures cause polar ice sheets to grow, not collapse. 🙄

PERIODIC TABLE OF THE ELEMENTS: Potential completion of the Periodic Table of the Elements: I currently believe that there are 120 chemical elements in this universe. If a person were to look at how electrons fill up the shells in atoms: 2, 8, 18, 32, 32, 18, 8 (seven shells), and realizing that energy could freely flow in this universe if nothing stopped it from doing so, then a natural bell shaped curve might occur. An eighth energy shell might exist with a maximum of two elements in it, chemical element #119 (8s1) and chemical element #120 (8s2). Chemical Element #119 (8s1): #119 I put at the bottom of the Hydrogen group on the Periodic Table of the Elements. It only has one electron in it's outer shell with room for only one more electron. Energy might even enter the atom through the missing electron spot and then at least some of the energy might get trapped inside of the atom under the atom's outer shell. Chemical Element #120 (8s2): #120 I put at the bottom of the Helium group since it's outer shell is full of electrons. It might have some of the properties of group two, Beryllium group (Alkali Earth Metals group) since it has two electrons in it's outer shell; as well as some of the properties of the Helium group (Noble Gases group) since it's outer shell is full of electrons; and if you look at the step down deflection of the semi-metals and where #120 would be located on the chart, it's possible #120 might even have some semi-metal characteristics. #120 would be the heaviest element in this universe. I believe chemical element #120 could possibly be found inside the center of stars. When a neutron split inside of this atom, it would give off one proton, one electron, neutrinos and energy. The proton and electron would be ejected outside of the atom since all their respective areas are full. One proton and one electron are basic hydrogen, of which the Sun is primarily made up of, and the Sun certainly gives off neutrinos and energy. And note, it's the neutron that split, not a proton. So even after the split, there are still 120 protons inside of the atom and the atom still exists as element #120. The star would last longer that way. In addition, if the neutron that split triggered a chain reaction inside of the star, this could possibly be how stars nova, (even if only periodically). If stars were looked at as if this theoretical idea were true, and found to even be somewhat true, then we might just have a better model of the universe to work with, even if it's not totally 100% true. And if it's all 100% true, then all the better. (Except of course for those who might be in the way of a periodic nova or supernova. They might have a no good, very bad, horrible day.)

@@personzorz LOL. the planet is already cooling. Greenland Ice mass balance has increased from a low in 2012 of 20 GT to being consistently over 300GT and 400GT last year. CO2 does not cause significant warming, compared to 1850 (The beginning of the Industrial Revolution) CO2 has only increased by 50'%, increasing the greenhouse effect by about 2W/m2 which the Stefan Boltzmann law tells us is less than 0.4degrees C of warming. For CO2 cause just 1 degree of warming compared to 1850 it would need to be 750ppm. and for another 'CO2driven' degree of warming would require a level of over 2000ppm. If you need an explanation of the recent warming look to the sun not a trace atmospheric gas. Hint; Big black spots on the sun and the planet cools a little, No Big black spots on the sun and the planet warms a bit (as happened during Maunder Minimum which warmed the planet out of the mini ice age (CO2 DID NOT CHANGE). The planet is following the Gleissberg Cycle, we have passed the recent minimum and we are on the way towards another cooling phase. One of the BIG benefits of the rise in CO2 has been a vast increase in food production. 50 years ago we could not produce enough food for 4 billion people with 1 million famine deaths every year.now we are feeding 8 billion people with fewer than 25,000 famine deaths. Int the last 50 years 3rd world crop yields per hectare have doubled while first world yields have quadrupled thanks the fertilizers and better seed, weed and pest control not available to the 3rd world.
