Right now our weather looks like this. And it's going to stay this way for at least a week.

Ann; please keep that slop over there! :lol2:
We had Ice jams under the Platte bridge a couple of weeks ago! I haven'e heard of update; so I am hoping the problem went away!

Sounds like the deep freeze is over! weather forecasters are calling for a string of days in the 30's and 40's! :D

Golly gee: two days ago we were supposed to get a blizzard like OMG! Lucky us it went up North a bit and we just got some ice cold rain! Tomorrow is supposed to reach the 70's! I guess you could say we are getting yo-yo weather :lol2: Anyway I hope that was the last cold blast!
I see Alabama is getting twister damage; hopefully they get some good weather now! I found out on the news that the USA is more prone to tornadic activity than any other country!

Yeah the internut is full o lots of garbage. The Maunder Minimum of low sunspot activity wasn't the cause of the Little Ice Age.

We don't know that. There are good arguments on both sides, as well as the possibility that it's not a binary issue at all. Bottom line is that this isn't something that is very well understood. There's no scientific consensus either way, so we should all be cautious getting overly attached to any explanation.

I didn't make that claim without reason. Quoting wikipedia's article on the "Little Ice Age":
Solar activity

Main article: Solar variation

There is still a very poor understanding of the correlation between low sunspot activity and cooling temperatures.[78][79] During the period 1645–1715, in the middle of the Little Ice Age, there was a period of low solar activity known as the Maunder Minimum. The Spörer Minimum has also been identified with a significant cooling period between 1460 and 1550.[80] Other indicators of low solar activity during this period are levels of the isotopes carbon-14 and beryllium-10.[81]

Volcanic activity

In a 2012 paper, Miller et al. link the Little Ice Age to an "unusual 50-year-long episode with four large sulfur-rich explosive eruptions, each with global sulfate loading >60 Tg" and notes that "large changes in solar irradiance are not required."[6]

Throughout the Little Ice Age, the world experienced heightened volcanic activity.[82] When a volcano erupts, its ash reaches high into the atmosphere and can spread to cover the whole earth. The ash cloud blocks out some of the incoming solar radiation, leading to worldwide cooling that can last up to two years after an eruption. Also emitted by eruptions is sulfur, in the form of sulfur dioxide gas. When it reaches the stratosphere, it turns into sulfuric acid particles, which reflect the sun's rays, further reducing the amount of radiation reaching Earth's surface.

A recent study found that an especially massive tropical volcanic eruption in 1257, possibly of the now-extinct Mount Samalas near Mount Rinjani, both in Lombok, Indonesia, followed by three smaller eruptions in 1268, 1275, and 1284 did not allow the climate to recover. This may have caused the initial cooling, and the 1452–53 eruption of Kuwae in Vanuatu triggered a second pulse of cooling.[6] The cold summers can be maintained by sea-ice/ocean feedbacks long after volcanic aerosols are removed.

Other volcanoes that erupted during the era and may have contributed to the cooling include Billy Mitchell (ca. 1580), Huaynaputina (1600), Mount Parker (1641), Long Island (Papua New Guinea) (ca. 1660), and Laki (1783).[21] The 1815 eruption of Tambora, also in Indonesia, blanketed the atmosphere with ash; the following year, 1816, came to be known as the Year Without a Summer,[83] when frost and snow were reported in June and July in both New England and Northern Europe.
The underline above was mine. I contend that something that occurred during the middle of an event couldn't have also been its cause. Maybe it (the Maunder Minimum) helped deepen or prolong the Little Ice Age, but there's no way the MM was the cause of the LIA. Volcanic activity makes much more sense as a primary driver for this climate event.

To be clear, the claim "the Maunder Minimum of low sunspot activity wasn't the cause of the Little Ice Age" is intellectually poor. We do not know the role that it played, nor are we even able to accurately date it. A better claim would be something less assertive, along the lines of "we have good reasons to doubt that the Little Ice Age was caused, or solely caused, by the Maunder Minimum".

When contending with junk science claims like the ones Orin linked to less assertive claims are weak, watered-down arguments. Or should we be ok with global warming denier fueling claims that the Sun is about to cause another Ice Age?

You claim Chris that my statement was "intellectually poor" while also choosing to ignore my quoted evidence. Is believing that for something to be a cause it must precede the alleged effect intellectually lacking?

I'm not an expert either Orin, but I strongly feel that those stories are indeed "False Science". They claim "NASA warns" but then site one or two "NASA scientist", but if that was really what the majority believed it would be a much bigger story. It's old fake news too, as those vids are from last year.

well; you might be right & you might be wrong; I don't know! However, I am a skeptic of today's media! You know; you control the masses and you control the world! I kinda stand by and watch things as they proceed! Kind of like next year isn't very far away! I'm so old anyway that it isn't going to affect me as much as most people! :lol2: :brr: :wink:

No need to take offense. The statement is intellectual poor because it states something very much in the form of a fact, for which no scientific consensus exists. The evidence you presented is all secondary. I can assure you, plenty of experts still consider it very possible that there's a relationship between the Maunder Minimum and the climate changes seen around the 16th century and after. It's not well understood, so it's wise not to take any position too strongly.

Ok, I'll de-ruffle my feathers. But my strongly held opinion remains that the stories hyping an eminent return to Little Ice Age climate because the Sun seems to be headed into a period of sunspot inactivity are garbage. From what I can gather from reading up on solar output during sunspot minimums the drop in average annual solar energy would only be about 0.1%. My opinion is that such a small decrease wouldn't be near enough to reverse AGW.

I don't disagree with your assessment of claims that a deep solar minimum will cause a new ice age. Indeed, everything we know about the Little Ice Age suggests that it was a weaker negative trend than the current positive one. At most, assuming a connection between solar activity and climate, we might expect a slight reduction in the rate of warming. Things are almost certainly going to keep getting hotter.

We're having a wild and crazy spring here in the Rockies. More than 6 inches of heavy, wet snow dropped on us last night. The temperature was above freezing most of the time. Bright and sunny today, with around 0.5" melted into my gauge so far. Today is graduation at Guffey School... if it were not, we might have called a snow day. I've been keeping track of our last snowfall since 1999. This is ten days later than any other, and twice as heavy. But it's sure doing wonders for the grass and flowers.

We have this unusual weather phenomenon today. There's this bright light in the sky and there is no liquid falling out of the sky. I've checked all of the local news stations but the weathermen are all strangely quiet.

The weathermen don't know what to make of it! :wink: I've been getting kind of tired of all the twisters; floods; and cold rains for the end of May! It's good to have that bright light in the sky for a change! 8-) Don't go out and get yourself overly tanned by that bright light! Bet the skeeters are going to start hatching now! :cry:

Lightning strikes one of the pylons of the Öresund Bridge.

We have had a lot of thunder and lightning where I live recently. Yesterday night, some spectacular lightning hit one of the pylons of the Öresund Bridge, which connects Malmö and Copenhagen.

Tonight there is a fine display of noctilucent clouds outside my kitchen window.
