Current Heat Wave
I hear every day, manmade Climate Change, and I say BS! I also hear follow the science, are they talking about VOODOO science?
Here is the science! The Disruption in the weather we are seeing today is caused by several factors happening at the same time. They are Solar activity, we are currently in a solar maximum, while at the same time we are seeing a "wobble" in the moon's orbit and rising sea levels, every coast in the United States will face rapidly increasing high tides that will start "a decade of dramatic increases in flood numbers" in the 2030s. But not only is the moon “wobble” causing a rise in sea levels but also the frequency of volcanic eruptions.
As the sun nears the peak of its current solar cycle, our star is growing increasingly active. And that peak may be occurring sooner than predicted, according to scientists.
Every 11 years or so, the sun experiences periods of low and high solar activity, which is associated with the amount of sunspots on its surface. These dark regions, some of which can reach the size of Earth or larger, are driven by the sun’s strong and constantly shifting magnetic fields.
“No two solar cycles are the same,” said Mark Miesch, research scientist at the Space Weather Prediction Center. “This solar maximum is the space weather equivalent of hurricane season. It’s when we see the biggest storms. But unlike hurricane season, which lasts a few months, solar maximum lasts a few years.”
A SECOND CME IS APPROACHING: Minor G1-class geomagnetic storms are likely on July 21st (1600 UT) when a CME is expected to hit Earth's magnetic field.
This would be the second day in a row a CME has struck. Yesterday's impact was weak and did not spark a geomagnetic storm, but it might have softened up our magnetosphere for a more effective strike today.
What is a “CME”
The disturbance that drives the magnetic storm may be a solar coronal mass ejection (CME) or (much less severely) a co-rotating interaction region (CIR), a high-speed stream of solar wind originating from a coronal hole. The frequency of geomagnetic storms increases and decreases with the sunspot cycle. During solar maximum, geomagnetic storms occur more often, with the majority driven by CMEs.
What is a “magnetosphere”
Earth is surrounded by a system of magnetic fields, called the magnetosphere. The magnetosphere shields our home planet from harmful solar and cosmic particle radiation, but it can change shape in response to incoming space weather from the Sun.
'Cannibal' coronal mass ejection that devoured 'dark eruption' from sun will smash into Earth on July 18

Two coronal mass ejections have combined into an enormous cloud of magnetized plasma that is forecast to hit Earth on Tuesday and potentially trigger a strong geomagnetic storm.
Solar flares striking the "magnetosphere" of the earth can act like a generator creating an electric current within the magnetosphere and heating the atmosphere. Which cause the weather on the Earth to get hotter
Geomagnetic storms and increased solar ultraviolet emission heat Earth's upper atmosphere, causing it to expand. The heated air rises, and the density at the orbit of satellites up to about 1,000 km (600 mi) increases significantly. This results in increased drag, causing satellites to slow and change orbit slightly. Low Earth orbit satellites that are not repeatedly boosted to higher orbits slowly fall and eventually burn up. Skylab's 1979 destruction is an example of a spacecraft reentering Earth's atmosphere prematurely as a result of higher-than-expected solar activity. During the great geomagnetic storm of March 1989, four of the U.S. Navy's navigational satellites had to be taken out of service for up to a week, the U.S. Space Command had to post new orbital elements for over 1000 objects affected, and the Solar Maximum Mission satellite fell out of orbit in December the same year.
Earth has already been hit by five G1 or G2 geomagnetic storms this year, including the most powerful storm for more than six years. These storms have superheated the thermosphere — the second-highest layer of Earth's atmosphere — to its highest temperature in more than 20 years.
The number of sunspots is also increasing as we approach solar maximum, reaching its highest total for almost 21 years in June.
As we have heard on the news auroras are now visible farther south!
When the energized particles from coronal mass ejections reach Earth’s magnetic field, they interact with gases in the atmosphere to create different colored light in the sky.
Global climate change, including long-term periods of global cold, rainfall, drought, and other weather shifts, may also be influenced by solar cycle activity.
The Maunder Minimum and the “Little Ice Age”
Times of depressed solar activity seem to correspond with times of global cold in history. The most famous example is the “Little Ice Age.”
·Between 1645 and 1715—during what we now call the “Maunder Minimum”—sunspots were exceedingly rare.
Specifically, there were only about 50 sunspots (instead of the usual 40 to 50 thousand) and harsh winters.
For 70 years, temperatures dropped by 1.8 to 2.7 degrees Fahrenheit.
Seven decades of freezing weather, corresponding with the coldest period of the Little Ice Age, led to shorter seasons and ultimately food shortages.
Conversely, times of increased solar activity have corresponded with global warming. During the 12th and 13th centuries, the Sun was active, and the European climate was quite mild.
What Solar Cycle Are We In Now?
We are now in Solar Cycle 25. Record-keeping of solar cycles began in 1755 with Solar Cycle 1.
In December, 2019, the sunspot numbers hit the solar minimum and “rock bottom” and the Sun passed from Cycle 24 into Cycle 25. The solar maximum or peak is predicted to happen in July, 2025

Thanks to a "wobble" in the moon's orbit and rising sea levels, every coast in the United States will face rapidly increasing high tides that will start "a decade of dramatic increases in flood numbers" in the 2030s.
The conclusion, which was published in the Nature Climate Change journal by NASA Sea Level Change Science Team from the University of Hawaii, has to do with the moon's orbit, which takes 18.6 years to complete, according to NASA.
For half of that time period, Earth's regular daily tides are suppressed with high tides at a low average and low tides happening at a higher rate. In the other half of the cycle, the opposite occurs.
"High tides get higher, and low tides get lower. Global sea-level rise pushes high tides in only one direction – higher. So half of the 18.6-year lunar cycle counteracts the effect of sea-level rise on high tides, and the other half increases the effect," NASA explains.
The moon is in its tide-amplifying cycle right now, and there is no cause for concern of dramatic flooding given sea levels in the U.S. haven't risen much. However, when the moon returns to the tide-amplifying cycle, the seas will have had nearly a decade to rise.
"The higher seas, amplified by the lunar cycle, will cause a leap in flood numbers on almost all U.S. mainland coastlines, Hawaii, and Guam. Only far northern coastlines, including Alaska’s, will be spared for another decade or longer because these land areas are rising due to long-term geological processes," NASA said Wednesday.
How severe will the floods be? In 2019, the National Oceanic and Atmospheric Administration reported more than 600 floods.
By the mid-2030s, scientists expect three to four times that amount.
NASA Administrator Bill Nelson said the combination of the moon's gravitation pull, which causes tides in the first place, and climate change are the reasons behind the expected flooding.
"Low-lying areas near sea level are increasingly at risk and suffering due to the increased flooding, and it will only get worse,” Nelson said in the statement.
The study also determined some floods could happen in clusters, meaning they may last more than a month. Depending on the positioning of the moon, sun and Earth, cities may experience a flood in consecutive days or every other day.
While the amount of flooding won't be as much as a hurricane causes, having such frequent flooding can result in heavy economic damage.
"If it floods 10 or 15 times a month, a business can’t keep operating with its parking lot underwater. People lose their jobs because they can’t get to work. Seeping cesspools become a public health issue," said Phil Thompson, an assistant professor at the University of Hawaii and lead author of the study.
NASA hopes the release of its findings will help at-risk cities take measures to prevent too much damage.
Rising sea levels already have made living on the coast risky. Some experts say it may have played a role in the catastrophic collapse of a condo building in Surfside, Florida.
Volcanic Eruptions
The rise and fall of sea level as ocean heat content fluctuates. After volcanic eruptions, the Earth cools and the heat content in the ocean drops, ultimately lowering sea level. The solid blue line is the average sea level rise of climate model simulations that include volcanic eruptions. The green line is the average from model simulations with the effect of volcanic eruptions removed, showing a smooth acceleration in the rate of sea level rise due to climate change. The blue line between the start of the satellite record and the present day is relatively straight — just as we see from actual satellite observations during that time — indicating that the rate of sea level rise has not accelerated. But in the future, barring another major volcanic eruption, scientists expect sea level to follow the gray dotted line, which is on the same accelerating path as the green line below it.
