May 31, 2019: A huge blue cloud of frosted meteor smoke is pinwheeling around the Arctic Circle. NASA’s AIM spacecraft spotted its formation on May 20th, and it has since circled the North Pole one and a half times, expanding in size more than 200-fold.
“These are noctilucent clouds,” says Cora Randall of the AIM science team at the University of Colorado. “And they are going strong.”
Noctilucent clouds (NLCs) in May are nothing unusual. They form every year around this time when the first wisps of summertime water vapor rise to the top of Earth’s atmosphere. Molecules of H2O adhere to specks of meteor smoke, forming ice crystals 80 km above Earth’s surface. When sunbeams hit those crystals, they glow electric-blue.
But these NLCs are different. They’re unusually strong and congregated in a coherent spinning mass, instead of spreading as usual all across the polar cap.
“This is most likely a sign of planetary wave activity,” says Randall."
I'd be interested in seeing noctilucent clouds myself. But we are still overcast here, in the 60's with flash flood warnings through tonight. Maybe it will rain all through the summer this year.
That has happened before.....
"Seven weeks after Easter in A.D. 1315, sheets of rain spread across a sodden Europe, turning freshly plowed fields into lakes and quagmires. The deluge continued through June and July, and then August and September. Hay lay flat in the fields; wheat and barley rotted unharvested. The anonymous author of the Chronicle of Malmesbury wondered if divine vengeance had come upon the land: “Therefore is the anger of the Lord kindled against his people, and he hath stretched out his hand against them, and hath smitten them.” Most close-knit farming communities endured the shortages of 1315 and hoped for a better harvest the following year. But heavy spring rains in 1316 prevented proper sowing. Intense gales battered the English Channel and North Sea; flocks and herds withered, crops failed, prices rose, and people again contemplated the wrath of God. By the time the barrage of rains subsided in 1321, over a million-and-a-half people, villagers and city folk alike, had perished from hunger and famine- related epidemics. Giles de Muisit, abbot of Saint-Martin de Tournai in modern-day Belgium, wrote, “Men and women from among the powerful, the middling, and the lowly, old and young, rich and poor, perished daily in such numbers that the air was fetid with the stench.” People everywhere despaired. Guilds and religious orders moved through the streets, the people naked, carrying the bodies of saints and other sacred relics. After generations of good, they believed that divine retribution had come to punish a Europe divided by war and petty strife. The great rains of 1315 marked the beginning of what climatologists call the Little Ice Age, a period of six centuries of constant climatic shifts that may or may not be still in progress.
And it has been rather wet in NW Europe in the last couple of months and now instead of the wrath of god they blame CO2 but interestingly it was still retribution for things humans had done.
I have a friend who is currently preparing a paper that demonstrates warming is economically beneficial; I hope to be able to provide details sometime soon, if he can ever get it published.
That is a great idea for a paper. Humans have prospered (multiplied) immensely thanks to the invention of modern fertilizer and a gradually warming climate.
This used to be considered self evident. It is why the warm periods were called 'climate optimum'. It is only recently that there has been the claim that a minor change in CO2 could cause runaway global warming - this is patent nonsense as the amount of CO2 in the atmosphere has been 10 times higher and not caused any thermal runaway.
"The rules are simple: They lie to us. We know they are lying. They know we know they are lying, but they keep lying to us and we keep pretending to believe them."
What effect these noctilucent clouds may have on the climate, I do not know. One thing I know for sure is how many internationally recognized climate models have accurately taken into account the formation of these clouds during a global solar minimum. None.
" Noctilucent clouds form when summertime wisps of water vapor rise to the top of the atmosphere. Water molecules stick to specks of meteor smoke, gathering into icy clouds that glow electric blue when they are hit by high altitude sunlight. EUV radiation can destroy those water molecules before they freeze. Less EUV during Solar Minimum could therefore give us more noctilucent clouds. Coincidentally, the 2019 season for noctilucent clouds began in late May just as the sun entered a period of sustained spotlessness. There hasn't been a sunspot for the past 30 days--a span that overlaps the recent record-setting displays. Apparently, no sunspots = a lot of electric blue. "
