A 1,000 km Long River May Be Flowing Deep Below Greenland’s Ice Sheet.

WHAT THE ARTICLE SAYS:

Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at Petermann Fjord, along the northern coast of the island. Updating ice sheet models with this open valley could provide additional insight for future climate change predictions. Radar surveys have previously mapped Greenland’s bedrock buried beneath two to three thousand meters of ice. Mathematical models were used to fill in the gaps in survey data and infer bedrock depths. The surveys revealed the long valley, but suggested it was segmented, preventing water from flowing freely through it. However, the peaks breaking the valley into segments only show up in areas where the mathematical modeling was used to fill in missing data, so could not be real. Christopher Chambers and Ralf Greve, scientists at Hokkaido University’s Institute of Low Temperature Science, wanted to explore what might happen if the valley is open and melting increases at an area deep in Greenland’s interior known for melting. Collaborating with researchers at the University of Oslo, they ran numerous simulations to compare water dynamics in northern Greenland with and without valley segmentation. The results, recently published in The Cryosphere, show a dramatic change in how water melting at the base of the ice sheet would flow, if the valley is indeed open. A distinct subglacial watercourse runs all the way from the melting site to Petermann Fjord, which is located more than 1,000 kilometers away on the northern coast of Greenland. The watercourse only appears when valley segmentation is removed; there are no other major changes to the landscape or water dynamics. “The results are consistent with a long subglacial river, but considerable uncertainty remains. For example, we don’t know how much water, if any, is available to flow along the valley, and if it does indeed exit at Petermann Fjord or is refrozen, or escapes the valley, along the way. If water is flowing, the model suggests it could traverse the whole length of the valley because the valley is relatively flat, similar to a riverbed. This suggests no parts of the ice sheet form a physical blockade. The simulations also suggested that there was more water flow towards the fjord with a level valley base set at 500 meters below sea level than when set at 100 meters below. In addition, when melting is increased only in the deep interior at a known region of basal melting, the simulated discharge is increased down the entire length of the valley only when the valley is unblocked. This suggests that a quite finely tuned relationship between the valley form and overlying ice can allow a very long down-valley water pathway to develop. “Additional radar surveys are needed to confirm the simulations are accurate,” says Greve, who has been developing the model used in the study, called Simulation Code for Polythermal Ice Sheets (SICOPOLIS). “This could introduce a fundamentally different hydrological system for the Greenland ice sheet. The correct simulation of such a long subglacial hydrological system could be important for accurate future ice sheet simulations under a changing climate.

RESPONSE:

SIGNIFICANT GEOLOGICAL ACTIVITY UNDERNEATH GREENLAND HAS BEEN IGNORED BY CLIMATE SCIENCE IN A SIMPLISTIC AND ACTIVISM DRIVEN UNDERSTANDING OF ALL GREENLAND ICE MELT EVENTS AS ATMOSPHERIC PHENOMENA DRIVEN BY FOSSIL FUELED GLOBAL WARMING THAT CAN THEREFORE BE ATTENUATED BY THE CLIMATE ACTION DEMANDED IN TERMS OF OVERHAULING THE WORLD’S ENERGY INFRASTRUCTURE FROM FOSSIL FUELS TO RENEWABLES. THIS IS HOW ACTIVISM CORRUPTS SCIENCE.

The Ocean’s Swirling Currents Are Migrating Poleward: OMG! OMG!

LINK: https://www.scientificamerican.com/article/the-oceans-swirling-currents-are-migrating-poleward/

WHAT THE ARTICLE SAYS:

Enormous, swirling gyres compose some of the world’s biggest and most important ocean currents. Found in the North and South Pacific, the North and South Atlantic, and the Indian Ocean, these massive, rotating currents help transport heat and nutrients around the globe. Now, new research suggests, they seem to be on the move. OMG! OMG! A recent study, conducted by scientists from the Alfred Wegener Institute in Germany and the Ocean University of China, finds major ocean gyres are steadily creeping toward the poles. Since the 1980s, they’ve been migrating by about a half mile each year. It’s already causing noticeable consequences, the researchers suggest. For one thing, ocean gyres tend to alter the sea levels around them. Scientists have already observed a distinct band of higher-than-average sea levels in the midlatitudes, including along much of the U.S. East Coast, a phenomenon some experts have chalked up to regional warming patterns and related changes in the structure of the ocean. But the new study suggests the movement of ocean gyres may also be playing a role. Gyres also help control the flow of heat and nutrients through the ocean. As they move, they can alter ocean ecosystems, affect certain fisheries and influence weather patterns. The study suggests the movement of gyres may already be linked to recent observed changes in the movement of hurricanes and the behavior of major atmospheric currents, like the jet streams. The exact causes of the migration are difficult to pin down. But the new study suggests climate change is at least partly to blame. The researchers examined satellite data on sea surface heights and temperatures from the 1980s through the present. Ocean gyres tend to have distinct sea levels and water temperatures compared with their surroundings, so they can be geographically identified using these kinds of measurements. The data suggests that the gyres have been steadily moving toward the poles for the last four decades. But not all of the trends are statistically significant, particularly for gyres in the Northern Hemisphere—in other words, statistical analyses suggest that the migration could be the product of natural climate variations. But climate model simulations would seem to suggest otherwise. The researchers ran two sets of simulations, one implying a world without climate change and one incorporating the influence of historical greenhouse gas emissions. In the simulations incorporating climate change, ocean gyres crept toward the poles, just as they do in the satellite record. This suggests that climate change at least has had a hand in the phenomenon. If global warming is indeed the culprit, then these kinds of poleward shifts might be expected to continue in the coming decades, with potentially “broad environmental and societal impacts,”

RESPONSE: THIS IS THE NULL HYPOTHESIS ISSUE IN CLIMATE SCIENCE DESCRIBED MORE FULLY IN THE RELATED POSTS BELOW. IN REAL SCIENCE, THAT WHICH IS TO BE PROVEN IS THE ALTERNATE HYPOTHESIS AND ITS NEGATION IS THE NULL HYPOTHESIS. THIS MEANS THAT IN HYPOTHESIS TESTS, SUFFICENT AND CONVINCING UNBIASED EVIDENCE MUST BE PROVIDED TO REJECT THE NULL HYPOTHESIS TO ACCEPT THE ALTERNATE HYPOTHESIS AND UNTIL THEN, THE NEGATION OR DENIAL OF THE PROPOSITION STANDS. THIS PROCEDURE IS NOT FOLLOWED IN CLIMATE SCIENCE WHERE THAT WHICH IS TO BE PROVEN IS THE NULL HYPOTHESIS AND IT STANDS AS TRUTH UNTIL DENIERS CAN PROVIDE SUFFICIENT EVIDENCE AGAINST IT. THIS KIND OF RESEARCH CANNOT BE CLAIMED TO BE SCIENCE. AS IN THE PERVERSE INTERPRETATION OF UNCERTAINTY IN CLIMATE SCIENCE, THE NULL HYPOTHESIS ISSUE IS ALSO EVIDENCE OF CONFIRMATION BIAS IN CLIMATE CHANGE RESEARCH. THESE METHODOLOGICAL ERRORS MAKE IT IMPOSSIBLE TO CLAIM THESE KINDS OF FINDINGS AS SCIENTIFIC EVIDENCE.

Google Earth’s historical 3D time lapses show the ravages of climate change

LINK: https://www.theverge.com/2021/4/15/22383964/google-earth-3d-timelapse-climate-change

WHAT THE ARTICLE SAYS

Google Earth’s 3D time-lapse feature lets you observe how Earth has changed from 1984 to 2020, allowing you to see just how much the devastating effects of climate change have already shaped the geography of the planet. It’s best for a landscape view of our world. It’s not about zooming in. It’s about zooming out. It’s about taking the big step back. We need to see how our only home is doing. The Timelapse feature will be available starting Thursday. To access it, launch Google Earth and then click or tap on the Voyager tab and search for a place of interest or take a “guided tour” about forest change, urban growth, warming temperatures, mining and renewable energy sources, and the Earth’s fragile beauty. Example below presented as a GIF image.
