VSF: Every night, Mr. ElectroMagnetics and I go over my screenshot images from NASA Worldview. With over 7000 images now, I am beginning to ‘play’ with the contrast, saturation, exposure, and other graphic controls that change the images. I was trained as a graphic designer at Parsons School of Design in New York City.
To my amazement, I am finding that electrified-looking spiral-coils and soft prismatic type colors lurk beneath white surfaces. Because the effects are always different, I do not believe that these colors and coils are a factor of the Worldview graphics program.
In the image (top above) there are prism colors of peach, pink, green, lilac. If any of you who have some idea what is causing these effects, or what they in fact are – feel free to email me. Can it be the angle of the Sun that is producing these colors? Or is it the chemicals in the various metals. If it was just the Sun, would not the colors be more uniform?

Antarctica Is Melting From Below—And It’s Getting Worse
By Sydney Pereira On 1/8/18
Antarctica’s ice shelves are melting from warming ocean waters below—even during seasons when snowfall on top of them is increasing. This strange paradox could worsen from the natural climate phenomenon El Niño, according to a study published Monday in Nature Geoscience. Based on 23 years of satellite data from the West Antarctic ice shelves, the study revealed that a strong El Niño event causes the shelves to lose more ice from melting beneath than they gain back from snowfall on top of it. …
The satellite data from 1994 to 2017 revealed the height of the ice decreased by eight inches per year overall from ocean melting, according to the study. But during the El Niño event in 1997 and 1998, the height increased by 10 inches. The fresh snowfall, however, is much less dense than the solid ice that makes up most of the shelf. The mass, which is the most important measurement in terms of sea level rise, was decreasing although the height increased during the event. The extra snowpack was minimal compared to how much solid ice melted from below. Ice shelves lost five times more ice from below than they gained back from fresh snowfall. …
Satellite records over two decades allowed researchers to look at the processes that affect ice shelves, which helps scientists better understand how ice sheets may melt in the future. Understanding the processes behind the melting of ice shelves could help pinpoint how soon and how much sea levels will rise. Ice shelves don’t cause sea level rise on their own. Rather, the ice sheets they hold back from slipping and melting into ocean water hold the fate of coastal communities around the world in their icy grip. Ice shelves, Paolo described, function like an ice cube.
