Huh? > [@](#): > > “suggest that _ **solar activity** _ will fall by 60 per cent during the 2030s to conditions last seen during the ‘mini ice age’ that began in 1645.” Emphasis mine … But the headline: > [@](#): > > Double-Dynamo Model Predicts 60% Fall In _ **Solar Output** _ In The 2030s … again emphasis mine … Clever bit of “bait and switch” if you ask me. They mean sunspots and flares and such when they say “solar activity”, rest assured there’s still 100,000 thermonuclear warheads worth of fusion happening every second in the core of the sun. Keep the SPF 10,000 sunscreen handy. ---

I read somewhere a few weeks ago why California is having this prolonged drought: There is a high-pressure ridge sitting over the north Pacific that has been just sitting there and sitting there and sitting there. (I infer that this high-pressure ridge has previously been a more transient thing.) It blocks all the wet air from the north Pacific from making it to land. So I guess it’s been raining as much as ever, except it’s all falling out there over the ocean. Apparently this ridge has become a stable and persistent feature, and there seems to be an implication that the global climate change is the cause of this. SO: If we have this little ice age, will that be a major break from the global climate trends of recent times? Will the high-pressure ridge dissipate or move away? Will it rain?

This result says that _if this model is correct_, we’ll see a major drop-off of solar activity in 2030 or 2040. Is the model correct? We’ll find out in 2030 or 2040.

This should break the drought in California. We’ll know for sure at the end of 2016 … Yeah, yeah, they said that _last_ summer too. Maybe this year will be IT? I read that El Nino brings torrential rain to _southern_ California but drier weather to the Pacific Northwest. If that’s so, I wonder how far north that rain will hit. As far north as the San Francisco area? As far as southern Oregon? Southern Washington? Vancouver? El Nino rains might not be a great solution for California drought anyway. It brings lots of rain, but it comes from the tropical Pacific region (the “Pineapple Express”) so it’s warmer rain, and it doesn’t produce a lot of snow pack in the Sierras, which is what California _really_ needs in order to have a repository of water to last all summer. ---

> [@Senegoid](#): > > Yeah, yeah, they said that _last_ summer too. Maybe this year will be IT? All I said was “above average probability” … [giggle] … hedging that bet for sure. The afore mentioned Northeast Pacific High Pressure ridge breaks down allowing the entire coast to get hit with storms, so the Maritime Pacific Northwest will still see adequate rainfall. I average 100" a year here, due to topography and elevation, a single Pineapple Express would dump 8" over a couple days. So that’s fairly small in comparison. The _El Nino_ conditions only break down the high pressure ridge. That would allow an atmospheric river event to occur in California, but only if an atmospheric river were to occur. AFAIK, there’s no cause and effect between _El Nino_ and Pineapple Expresses. They’re not exactly common, maybe average one every third year. That’s why it was startling to get two in month, especially since I had just finished touring California’s drought devastated Central Valley. Thank God OUR reservoirs were empty … But back to the subject, I predict that the rainy season in California will start out normally, with maybe a bit above average rainfall until mid-November. Then the air flow will switch and come from the Northwest straight out of the Gulf of Alaska. This will bring lots and lots and lots of wet sloppy snow down to a very low elevation, I’m thinking 25,000 sq miles covered four feet deep in a couple weeks. That’s not a big stretch if the snow level is only 1,000 foot elevation. Then the air flow will switch again this time from the Southwest, directly from sub-tropical Hawai’i. Plume after plume of 60ºF heavy rainfall causing 6" of rain every day for a week on top of all the wet sloppy snow. The Army Corp of Engineers already know what to do, they’ll have opened all the floodgates on all the dams in the Sierras by this time because they’re not allowed to let their dams get over-topped. The Carquinez Strait isn’t wide enough to allow all that water to flow out into San Pedro Bay (a part of San Francisco Bay), the backed up water will form an inland lake running from Turlock to Colusa, Sacramento and Stockton will be under 40 feet of water and the water under the Golden Gate bridge will be fresh, just boil it and you’ll be able to drink it. No Pineapple Express required … ---

[Here’s](http://www.slate.com/blogs/bad_astronomy/2015/07/14/global_cooling_no_were_not_headed_for_a_mini_ice_age.html) **The Bad Astronomer** ’s take on this.

Much of the previous ballyhoo about the Maunder Minimum being such a cold era as well as it being linked to sunspot cycles has been debunked. E.g., the Thames freezing over may have been more due to narrow bridge pilings than cold temperatures. Remember, we just went thru a very low sunspot cycle. And things continued to get warmer. ---

Read that link for the details, but here’s a synopsis: > > In a nutshell, the Sun goes through an 11-year cycle of magnetic activity. When it peaks, sunspots are more common. You might think that means less heat from the Sun, since sunspots are cooler and darker. But they have bright rims (called faculae) that more than make up for the cooler interior regions.

No one really knows. There has been research asking what would happen if it is weak next time and concludes it will have moderate localized effects—not global cooling.

Any cooling effects by the Sun would be on top of a much larger heating trend due to global warming. Climate scientist Gavin Schmidt put out a series of tweets showing why (similar to what I’ve written here), and don’t forget that 2015 is gearing up to be the hottest year on record, too. My Slate colleague Eric Holthaus has written about this as well, and Think Progress also has a good article on it. > > Of course, the usual suspects are running with this.

Sure, the Sun’s influence is overwhelmed, but not completely, the _rate_ of solar energy input directly effects the _rate_ of Global Warming. Also the _rate_ of change of CO[sub]2[/sub] concentrations direct effect the _rate_ of Global Warming … one equation in two variables both of which change with respect to time … that’s why UCLA requires two years calculus before they’ll let you take Climatology. > … Not sure why then we should ignore what the majority of the experts are telling us, they already did go through all that. ---

Doesn’t your rain year begin Oct 1[sup]st[/sup]? Then I guess we’d have a very good idea by August of 2016, by then the new lake will have reached maximum levels.
