Mysterious triangle looking like a cloaked craft appears in the sky over Kansas City, Missouri, Miami, Florida and Canada
This huge triangle was observed in the sky over Kansas City, Missouri, then on August 8, 2018, while driving south along the I-35 highway. What could this be? The strange shape in the clouds was observed for 3 minutes by the eyewitness.
As he drove out of the highway to the north, the mysterious shadow (of an unidentified flying object?) also disappeared behind the trees on the horizon.

'Really Extreme' Global Weather Event Leaves Scientists Worried


Climate scientists are used to seeing the range of weather extremes stretched by global warming but few episodes appear as remarkable as this week's unusual heat over the Arctic.
Zack Labe, a researcher at the University of California at Irvine, said average daily temperature above the northern latitude of 80 degrees has broken away from any previous recordings in the past 60 years.

"To have zero degrees at the North Pole in February - it's just wrong," said Amelie Meyer, a researcher of ice-ocean interactions with the Norwegian Polar Institute. "It's quite worrying."
The so-called Polar Vortex - a zone of persistent low-pressure that typically keeps high-latitude cold air separate from regions further south - has been weakening for decades.
In this instance, "a massive jet of warm air" is penetrating north, sending a cold burst southwards, said Dr. Meyer, who has relocated to Hobart to research on the southern hemisphere, and is hosted by Australia's Integrated Marine Observing System.

"The anomalies are really extreme," Andrew King, a lecturer in climate science at the University of Melbourne, said. "It's a very interesting event."

Warm, moist air is penetrating much further north than it would normally at a time when the North Pole is in complete darkness.
Cape Morris Jessup, the world's most northerly land-based weather station, in Greenland, touched 6 degrees late on Saturday, about 35 degrees above normal for this time of year.
Robert Rohede, a Zurich-based scientist with Berkeley Earth, posted on Twitter that Cape Morris Jessup had already recorded 61 hours above freezing so far in 2018.
The previous record of such relative was just 16 hours recorded to the end of April in 2011.
"Parts of Greenland are quite a bit warmer than most of Europe," Dr King said.
The cold snap will sink temperatures moderately below freezing in London each day until Friday. However, cities such as Berlin will dive to as low as minus 12 degrees and Moscow to minus 24.
With a weak jetstream, surface winds are taking an unusual course - bringing snow from the east and prompting some commentators to dub the event the "Beast from the East".
"For Britain and Ireland, most weather systems would typically blow in from the west, but [on Tuesday] we will see a cold front cross Britain from the east," Dr King said.
 Along with the unusual warmth over the Arctic, scientists are monitoring the retreat of sea ice in the Bering Sea.
The ice coverage in the region is now at levels previously seen only in May or June, Mr Labe posted on Twitter, citing data from the US National Snow and Ice Data Centre.
While climate change itself is only likely to have exacerbated regional weather variability, the long-term shrinkage of sea ice has a reinforcing effect on global warming in a region already warming faster than anywhere else on the planet, Dr King said.
Ice reflects sunlight back to space. When it melts, the sea ice exposes more of the dark ocean beneath, which then absorbs that solar radiation, adding to the warming.
Sea ice coverage is currently at or close to record low levels in both the Arctic and Antarctic regions.
The impact of the relatively warm air in the Arctic could play out for months to come. Multi-year ice is likely to be thinner and more cracked, leading to a faster melt when spring arrives, Dr. Meyer said.
While researchers had pegged 2050 as a possible year when the Arctic will become ice-free, this winter and the previous one - also unusually warm - had thrown those estimates out.
"It's going much faster than we thought," said Dr. Meyer, who will begin work later this year at the ARC Centre of Excellence for Climate Extremes.
