Top-secret Cold War project found disturbing 'life-like' fossil plants under Greenland

EXCERPTS: . . . . Recent analysis revealed plants that were so well-preserved they "look like they died yesterday," researchers said. U.S. Army scientists dug up the ice core in northwestern Greenland in 1966 as part of Project Iceworm, a covert mission [...] the ice core lay forgotten in a freezer in Denmark until it was rediscovered in 2017.
When scientists investigated the core in 2019 they discovered fragments of fossilized plants that may have bloomed a million years ago. Greenland's present ice cover was thought to be nearly 3 million years old, but the tiny plant fragments say otherwise, showing that at some point within the last million years — possibly within the last few hundred thousand years — much of Greenland was ice-free.
[...] If the new research bears out and most of Greenland's ice vanished relatively recently, that doesn't bode well for the stability of its current ice sheet in response to human-caused climate change. Should all of Greenland's ice melt, the seas would rise by approximately 24 feet (7 meters), the National Oceanic and Atmospheric Administration (NOAA) reported in 2019. That would be enough to flood coastal cities worldwide, the researchers wrote in the new study, published March. 15 in the journal Proceedings of the National Academy of Sciences... (MORE - details)
Martian orange veil of dust chokes Beijing in record-breaking sandstorm
https://www.livescience.com/massive-sand...ijing.html
INTRO: Beijing has been enveloped in one of its most severe sandstorms in over a decade, which has combined with air pollution to create a toxic, gritty haze that turned skies orange and made the skyline disappear. The sandstorm hit the Chinese capital on Monday morning (March 15) after gale-force winds from Mongolia blew dust from the Gobi desert over the border. In Mongolia, 341 people are missing after the same sandstorm blew across the country, according to The Guardian... (MORE)
