An Antarctica heat wave melted 20% of an island's snow in 9 days By Scottie Andrew, CNN 12 hrs ago A nine-day heat wave scorched Antarctica's northern tip earlier this month. New NASA images reveal that nearly a quarter of an Antarctic island's snow cover melted in that time -- an increasingly common symptom of the climate crisis. © NASA The images show Eagle Island on the northeastern peninsula of the icy continent at the start and end of this month's Antarctic heat wave. By the end of the nine-day heat event, much of the land beneath the island's ice cap was exposed, and pools of meltwater opened up on its surface. Antarctica experienced its hottest day on record earlier this month, peaking at 64.9 degrees Fahrenheit. Los Angeles measured the same temperature that day, NASA said. In just over a week, 4 inches of Eagle Island's snowpack melted -- that's about 20% of the island's total seasonal snow accumulation, NASA's Earth Observatory said. "I haven't seen melt ponds develop this quickly in Antarctica," Mauri Pelto, a geologist at Nichols College in Massachusetts, told NASA's Earth Observatory. "You see these kinds of melt events in Alaska and Greenland, but not usually in Antarctica." Climate scientist Xavier Fettweis plotted the amount of meltwater that reached the ocean from the Antarctic peninsula. The heat wave was the highest contributor to sea level rise this summer, he said. A perfect storm of conditions for a heat wave As Pelot noted, melt events like this are quite rare for Antarctica, even during the summer. It's one of the coldest places on Earth. This heat wave was the result of sustained high temperatures, he said, which almost never occurred on the continent until the 21st century. It's the kind of weather event that grows increasingly common as global temperatures rise. This month, high pressure over Cape Horn in Chile's archipelago allowed warm temperatures to build up and travel. Antarctica's northernmost peninsula is typically protected from these high temperatures due to strong winds that cross the Southern Hemisphere, but those winds were unusually weak and couldn't stop the high temperatures from penetrating the continent's northern tip, NASA reported. Ice caps in Antarctica are already melting rapidly due to heat-trapping gas pollution from humans. Rising sea levels could be catastrophic for the millions of people who live along the world's coasts: Antarctica's ice sheets contain enough water to raise global sea levels by nearly 200 feet, according to the World Meteorological Organization. And earlier this month, a massive iceberg along the western edge of Antarctica broke off from the Pine Island Glacier. The 116 square mile-chunk of ice likely fractured as a result of warmer sea temperatures, and it's evidence that the glacier is quickly responding to climate change, the European Space Agency said.

Massive deception. BY OBVIOUS DESIGN. Eagle Island location: Latitude at approx 63rd parallel SOUTH. Map location: Just south of the tip of South America, near the northern tip of the alleged "continent" of the unexplored, restricted Antarctica realm. In the Northern Hemisphere, at approx the 61rd parallel or latitude (NORTH) is Anchorage, Alaska. Oslo (Norway) Airport is 60 degrees north. The 63rd parallel NORTH divides BOTH Alaska and Norway in half. During the Summer in both places, temperatures often reach 75 degrees F or more. (Are so-called "scientists" and NASA Sci-Fi Trekkies worried about THAT?) This is more "Climate Change" fear-porn "science" from NASA. *Source of the referred NASA "images" (note: NOT referred to as "photos"): 'Landsat'. What is a "landsat'?: Different sensors attached to WEATHER BALLOONS FWIW, you can see Eagle Island on this map near the bottom (@ "ANTARCTICA" arrow) Just OUTSIDE the supposed 'Antactica Circle'.
I also see the Falkland Islands on the map. The British and Argentinians had a war over those islands in 1982. The British had replaced some of the steel in their ship's superstructure with aluminum. The Argentinians had gotten hold of French Exocet anti-ship missiles. the British lost some tonnage on that account since when aluminum catches fire it is nearly impossible to put it out unless you starve the fire of oxygen. ;)

Yup -- pretty far down there. The Falkland war was pretty bizarre, given the supposed cause and stakes. Then again, isn't all globalist war-theater based on the flimsiest of excuses? The Argentinians had gotten hold of French Exocet anti-ship missiles. The British lost some tonnage on that account since when aluminum catches fire... Some cynics claim this "war" was merely an exercise and excuse to test certain military hardware and materiel. Casualties are incidental.
