It surely looks like the solar minimum has arrived, and it has done so far earlier than expected! On Sunday NOAA posted its monthly update of the solar cycle, covering sunspot activity for March 2018...the least active month for sunspots since the middle of 2009, almost nine years ago. In fact, activity in the past few months has been so low it matches the low activity seen in late 2007 and early 2008, ten years ago when the last solar minimum began.

A picture of dark sunspots and bright diffuse faculae (best seen around the edges). The study shows how the larger mix of heavy elements leave the spots unchanged, while increasing the contrast of the bright diffuse faculae. Credit: NASA/SDO ============================================================================================================================ The spots on the surface on the sun come and go with an 11-year periodicity known as the solar cycle. The solar cycle is driven by the solar dynamo, which is an interplay between magnetic fields, convection and rotation. However, our understanding of the physics underlying the solar dynamo is far from complete. One example is the so-called Maunder Minimum,...

Fewer sunspots (weaker solar winds), allow more cosmic rays to enter the Earth’s atmosphere to ionize aerosol molecules, which condense into clouds that cause cooling. More sunspots have the opposite effect — fewer clouds — warmer surface temperatures. Whether present cooling continues or not, is there any reason at all to panic? No, and by the same token, when that good old global warming resumes — as it undoubtedly will along with intermittent cool-downs — let’s remember present conditions and be doubly grateful.

International Falls, Minnesota woke up to a temperature of -36F at 6 a.m. Wednesday morning breaking the previous record low for Dec. 27 of -32F set in 1924, according to the National Weather Service office in Duluth. That -36 is the actual temperature, not a wind chill! According to state records, the -36 morning in International Falls is only about halfway to the state record low temperature of -60 in Tower, Minnesota on Feb. 2, 1996. The all-time record low for International Falls is -55F, set in January 1909. Wednesday morning, low temperatures in the Twin Cities metro ranged from...

NASA’s own data is showing that the star our globe revolves around is dimming. With no sunspots reported in 96 days, the sun is going dark and the evidence could point to an approaching ice age. As the sun gets successively more blank with each day, due to lack of sunspots, it is also dimming, says the website Watts Up With That? According to data from NASA’s Spaceweather, so far in 2017, 96 days (27%) of the days observing the sun have been without sunspots. Today at Cape Canaveral, SpaceXlaunched a new sensor to the International Space Station named TSIS-1....

As the sun gets successively more blank with each day, due to lack of sunspots, it is also dimming. According to data from NASA’s Spaceweather, so far in 2017, 96 days (27%) of the days observing the sun have been without sunspots. Here is the view today from the NASA Solar Dynamics Observatory satellite: Today at Cape Canaveral, SpaceX launched a new sensor to the International Space Station named TSIS-1. Its mission: to measure the dimming of the sun’s irradiance. It will replace the aging SORCE spacecraft. NASA SDO reports that as the sunspot cycle plunges toward its 11-year minimum,...

The sun is heading into a period known as solar minimum, during which activity at the surface will ‘change form.’In this time, certain types of activity, such as sunspots and solar flares will drop – but, it’s also expected to bring the development of long-lived phenomena including coronal holes. According to NASA, solar minimum could also enhance the effects of space weather, potentially disrupting communications and navigation systems, and even causing space junk to ‘hang around.’

Overview The sun has been completely spotless on 21 days in 2016 and it is currently featuring just one lonely sunspot region. In fact, on June 4th of this year, the sun went completely spotless for the first time since 2011 and that quiet spell lasted for about four days. Sunspot regions then reappeared for the next few weeks on a sporadic basis, but that was followed by several more completely spotless days on the surface of the sun. The increasingly frequent blank sun is a sign that the next solar minimum is approaching and there will be an even...

You may not have noticed but our sun has gone as blank as a cue ball. As in, it’s lost its spots. According to scientists, this unsettling phenomenon is a sign we are heading for a mini ice age. Meteorologist and renowned sun-watcher Paul Dorian raised the alarm in his latest report, which has sparked a mild panic about an impending “Game of Thrones”-style winter not seen since the 17th century. “For the second time this month, the sun has gone completely blank,” Dorian says. “The blank sun is a sign that the next solar minimum is approaching and there...

Astonishing images from NASA reveal no visible sunspots are currently visible on its surface. This has caused the star to go into "cue call" mode having entered its quietest period for more than a century, Vencore Weather claims. Decreased activity is not unusual as solar activity changes the volatile star's surface in 11-year cycles, astronomers say. But researchers are warning this current cycle could have a devastating impact on Earth's atmosphere, possibly ushering in a second ice age, similar to the one which began in 1645. Paul Dorian of Vencore Weather says the blank Sun is a sign that the...

Just hope that the current interglacial period will last for a few more decades to come. Anything else would spell disaster for much of mankind! Lyuba, of course, is the name bestowed upon the baby mammoth that was found a few years ago in the western Siberian tundra. The baby woolly mammoth is thought to be around 40,000 years old (by now) and is thought to have died by drowning at the age of two months. What’s so remarkable is Lyuba’s state of preservation, almost life-like, with skin and (sparse) hair fully intact. That kind of find is most uncommon.

NASA has revealed that a massive hole, measuring more than ten per cent of the Sun's surface area, has opened up on our star. ... NASA says the huge hole is actually not of great concern, but it remains unclear why the coronal holes actually form. ..

Blizzards, like the one that battered the East Coast this weekend, have doubled in number over the past 20 years. From 1960-94, the US had an average of nine blizzards per year. Since 1995, that annual average has risen to 19. And it's not just their frequency that's increasing. More blizzards are forming outside the normal storm season of October to March, scientists have found.

Those who think the political war on carbon will cool the globe or keep climate stable need to study climate history. Temperatures on Earth dance to a cyclic rhythm every hour, every day, every month, every season, every year, and to every beat of the sun-spot and glacial cycles. The daily solar cycle causes continual changes in temperature for every spot on Earth. It produces the frosts at dawn, the mid-day heat and the cooling at sunset. It is regulated by rotation of the Earth. Superimposed on the daily solar cycle is the monthly lunar cycle, driven by the orbit...

New studies flip climate-change notions upside down The sun will go into "hibernation" mode around 2030, and it has already started to get sleepy. At the Royal Astronomical Society's annual meeting in July, Professor Valentina Zharkova of Northumbria University in the UK confirmed it - the sun will begin its Maunder Minimum (Grand Solar Minimum) in 15 years. Other scientists had suggested years ago that this change was imminent, but Zharkova's model is said to have near-perfect accuracy. So what is a "solar minimum"? Our sun doesn't maintain a constant intensity. Instead, it cycles in spans of approximately 11 years....

The NOAA Climate Prediction Center’s updated 2015 Atlantic Hurricane Season Outlook calls for a 90 percent chance of a below-normal hurricane season. A below-normal season is now even more likely than predicted in May, when the likelihood of a below-normal season was 70 percent. “Tropical storms and hurricanes can and do strike the United States, even in below-normal seasons and during El Niño events,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster with NOAA’s Climate Prediction Center. “Regardless of our call for below-normal storm activity, people along the Atlantic and Gulf coasts should remain prepared and vigilant, especially now that...

So…the science isn’t settled after all? Patrick Moore, co-founder of Greenpeace, explains why “climate change,” far from being a recent human-caused disaster, is, for a myriad of complex reasons, a fact of life on Planet Earth. Of course religion is based on faith, not fact. And since Climate Change is the only religion many Warmers have you can expect them to stick to their guns and cling to their religion.Which is odd, since Marxists are generally opposed to religion. Butt when religion becomes this useful, they simply can’t help themselves. It’s like manna from heaven.So let me be perfectly clear:...

Explanation: How do sunspots evolve? Large dark sunspots -- and the active regions that contain them -- may last for weeks, but all during that time they are constantly changing. Such variations were particularly apparent a few weeks ago as the active region AR 2339 came around the limb of the Sun and was tracked for the next 12 days by NASA's Solar Dynamic Observatory. In the featured time lapse video, some sunspots drift apart, while others merge. All the while, the dark central umbral regions shift internally and their surrounding lighter penumbras shimmer and wave. The surrounding Sun appears...

A third, much faster coronal mass ejection (CME) is expected to catch up with the two observed on 18 and 19 June bringing them all to Earth in close succession by the UTC day of 22 June 2015. The CME was associated with an R1-Minor flare event observed at 0142 UTC (9:21 pm ET) from Sunspot Region 12371 located near center disk. A G3-Strong Geomagnetic Storm Watch has been issued for 22 June as well as a G2-Moderate Watch for 23 June as the CMEs make their way past Earth. These Watches supersede all prior forecasts. Stay tuned to...

The sun is almost completely blank. The main driver of all weather and climate, the entity which occupies 99.86% of all of the mass in our solar system, the great ball of fire in the sky has gone quiet again during what is likely to be the weakest sunspot cycle in more than a century. The sun's X-ray output has flatlined in recent days and NOAA forecasters estimate a scant 1% chance of strong flares in the next 24 hours. Not since cycle 14 peaked in February 1906 has there been a solar cycle with fewer sunspots. We are currently...
