Another recent scientific report documents how the Antarctic Ice Sheet, which we have been propagandized to zealously believe is one of the major players in rising sea levels, has actually gained, not lost, ice in the previous decade or so. The study found that, “Between 2002 and 2010, the AIS lost mass at a rate of about 73.79 Gt/year, a figure that doubled to 142.06 Gt/year during the 2011 to 2020 period.” These finding obviously challenge the “narrative of consistent mass loss in the region.” The same is actually true for the Australia coral reef too.This is one of many stories that in fact not just challenges the repeated narrative(s), but essentially destroys them. With more ice comes more reflection of sunlight, something universities, billionaires, and even governments have finally admitted to doing, or wanting to do, themselves. As the official narrative around melting ice likewise melts away, we are at a turning point where the introduction of geoenginering programs - which have been around for decades - will likely be given credit for reversing the melting of the various icy regions of earth. At the very least, they'll be given credit for reversing climate change. But it's not CC that has been reversed; instead, it's the narrative. The same narrative is changing around overpopulation, too, and not just because people are figuring out there is a difference between the overcrowding of cities and overpopulation of the planet. A recent report suggests that we may have underestimated the number of humans on the planet. This is especially coincidental considering birth rates are falling globally and population is on the verge of a steep drop off. Likewise, the narrative about starvation and lack of available food, while certainly true for some very specific regions of the planet, is rapidly changing as well. For example, the U.S. wastes about 40% of its entire food supply due due to expiration date confusion or the simple wasting of produce - about 60 million tons. Interestingly, about half of what we buy is ultraprocessed junk. Outside the U.S. the whole world “wastes about 2.5 billion tons of food every year.” In other words, there is plenty of food - so much, we waste near half of it every year. With just these few examples, you can see that we don't have a melting ice issue, we don't have an overpopulation issue, we don't have a food scarcity issue, etc. We have a reporting and narrative issue. These lies have spread so rapidly through society that they have become like a religious doctrine. Showing people the evidence provided here is irrelevant to their predetermined conclusions, which justify genetic engineering, geoengineering, synthetic biology, synthetic food, and the like through the lens of saving the world. In the process of trying to “save the world” these “solutions” threaten to make humans extinct. In other words, it's not the threat of something like climate change, which is evidently false and misleading, but instead the solution offered to fight it that threatens to extinct mankind. Perhaps that was the goal all along, because to eliminate C02 is to eliminate all current life on the planet. Now you see man, now you don't. And the elimination of “all current life” doesn't have to be literal extermination, it can be the promotion of having more kids via a Team Humanity that support synthetic biology, electric cars, microchips, a grid of satellites, etc, all things that make humans more obsolete, and renders them as nothing more than the information and energy resources for AI. *The is the FREE archive, which includes advertisements.

Dr. Michelle Guitard is a paleoceanographer interested in understanding the interactions between Antarctica's ice shelves and ice sheets and the surrounding ocean. A paleoceanographer is a scientist who uses natural archives to study how the marine environment changed through time. The natural archive that she relies on are sediment cores, which contain layers of mud that provide a snapshot of the environment in which the mud was deposited. Her work is focused on reconstruction the history of the Antarctic ice sheet through the Pleistocene (last 2.5 million years) and the Holocene (12,000-2.5 million years ago), studying how the outlet glacier systems in East Antarctica evolved. On this episode, we discuss her work and Antarctic fieldwork, getting her Ph.D., gender and racial diversity among doctorates in earth, atmospheric and ocean sciences. Her research has implications for understanding the stability of the entire Antarctic Ice Sheet, which be critical for predicting how Antarctica will respond to a warming climate.

Ricarda Winkelmann Colder, windier, drier than anywhere else on the globe - Antarctica is a continent of superlatives. It is covered by a massive ice-sheet, storing water equivalent to more than 50 meters of global sea-level rise. The ice is constantly moving, flowing from the continent's interior towards the ocean - forming, melting, re-freezing, breaking. To this day, these complex dynamics of the Antarctic Ice Sheet are the key challenge for projections of future sea-level rise under climate change. Recent observations show that part of the West Antarctic Ice Sheet is rapidly retreating, and that this retreat is likely irreversible on human timescales. Other regions are currently protected by so-called ice plugs, small volumes of ice which hinder the onset of a dynamic instability. However, man-made climate change increases the risk of triggering persistent ice discharge from the adjacent basins into the ocean. We will review the processes behind these dynamic (in)stabilities and explore the implications for future sea-level rise. Burning all of the world's available fossil-fuel resources could eventually result in the complete melting of the Antarctic Ice Sheet and cause long-term global sea-level rise unprecedented in human history.

Antarctic ice-sheet instability A new study models how the ice sheets in Antarctica will react if greenhouse gases rise at a medium to high rate. They predict the most likely outcome is a rise in global sea level of about 10cm by 2100. Previous research had put this figure at 30cm: this has not been ruled out by the new research, but it's been ruled much less likely. Groundwater The Earth's groundwater has been quantified - it's estimated to be 23 million cubic km. (which is equivalent to the Earth's entire land surface covered in a layer some 180m deep.) However, just 6% of the water is available for our use and to take part in the hydrogeological cycle. That small fraction is referred to as "modern" groundwater: it is extractable because it is near the surface, and can be used to supplement above-ground resources in rivers and lakes. But it's also the most sensitive to over use, climate change and to human contamination. Fluorescent coral Adam visits the National Oceanographic Centre in Southampton to see some fluorescent corals and asks how they can be utilised for medical imaging. Accents How are our accents changing? A three year study at University of Glasgow has found that Scottish accents haven't changed as much as English accents (which have become much more homogenised over the past 100 years). By listening to recordings from first World War Scottish prisoners of war, the Sounds of the City project has noticed that changes to Glaswegian accents have occurred over a much longer time frame than previously thought. But these changes have occurred locally - not in the same way or to the extent that it is thought English accents have evolved. Producer: Fiona Roberts.
