Report indicates solar cycle (below insert) has been impacting Earth since the Industrial Revolution

Some researchers believe that the solar cycle influences global climate changes. They attribute recent warming trends to cyclic variation. Skeptics, though, argue that there's little hard evidence of a solar hand in recent climate changes.


 

 

Experimental Link Found Between Sun and Climate

Evidence that solar variations impact both temperature and rainfall.

The exact causes of climate change remain a mystery to science. Many researchers link recent global warming to changes in the sun. Others remain skeptical, claiming that the sun varies only very slowly, over periods of millions of years. They say that no hard evidence exists for a solar effect on recent climate changes.

Now, new research may have provided just that evidence, with data demonstrating that solar variations have had major effects on the earth's climate as recent as 2,000 years ago. The research, conducted by a team of scientists from the Universities of Ohio, Minnesota, and Texas at Arlington, confirms that, during periods when the earth received less solar radiation, the Atlantic Ocean cooled, rainfall levels dropped, and North America experienced periods of intense drought. Some droughts lasted as long as a century.

Seven such events were detected, occurring once every 1,500 years, a period that matches the so-called "Bond Events" cycle of solar variation.

According to the study's lead author, Greg Springer, the correspondence provides "convincing evidence" of a solar effect on North American climate. "This really nails down the idea of solar influence on continental drought," said Springer.

The critical data was obtained from an 8-inch long stalagmite from a cave in West Virginia. As the stalagmite grew over a period of several thousand years, its composition precisely recorded fluctuations in the Earth's climate.

Data more recent than 2,000 years ago wasn't examined, as the authors feared the impact of Native Americans on nearby watersheds may have influenced the results. However, Springer tells DailyTech that analysis of river discharges around the area confirm that the region is still being impacted by such changes today.

The stalagmite was sampled at various points along its length, each point radiologically dated to precisely determine its age. Samples were analyzed to determine the ratio of strontium to calcium, along with levels of the isotopes carbon-13 and oxygen-18. Each of these acts as a proxy (indicator) for various climate parameters such as rainfall levels and land or sea-surface temperatures. The stalagmite therefore acts as a highly accurate record of climate variations over a period as little as a few years.

Spectral analysis of the data revealed cycles with periods corresponding to harmonics of the 1500-year Bond Events, a cycle triggered by weak solar activity which results in dramatic cooling and the occurrence of "IRD" events -- ice raft debris forming in the Atlantic.

Springer tells DailyTech that the results "certainly lends support" to global warming skeptics. However, he himself is not sure that the recent level of variance is enough to explain all the warming the Earth has undergone in the past 100 years.

Last year, scientist S. Fred Singer published the book, Unstoppable Global Warming (Every 1500 years), which tied current warming to an ongoing Bond Event. Singer tells Daily Tech that this new study provides further evidence for a 1500-year Climate cycle, the evidence for which was first discovered in ice core data.

The research is appearing in an upcoming edition of Geophysical Research Letters.


 

Now, a new research report from a surprising source may help to lay this skepticism to rest.

 

A study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate data over the past century has concluded that solar variation has made a significant impact on the Earth's climate. The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution.

Past research has shown that the sun goes through eleven year cycles. At the cycle's peak, solar activity occurring near sunspots is particularly intense, basking the Earth in solar heat.

 

According to Robert Cahalan, a climatologist at the Goddard Space Flight Center,

"Right now, we are in between major ice ages, in a period that has been called the Holocene."

Thomas Woods, solar scientist at the University of Colorado in Boulder concludes,

"The fluctuations in the solar cycle impacts Earth's global temperature by about 0.1 degree Celsius, slightly hotter during solar maximum and cooler during solar minimum. The sun is currently at its minimum, and the next solar maximum is expected in 2012."

According to the study, during periods of solar quiet, 1,361 watts per square meter of solar energy reaches Earth's outermost atmosphere. Periods of more intense activity brought 1.4 watts per square meter (0.1 percent) more energy.

While the NASA study acknowledged the sun's influence on warming and cooling patterns, it then went badly off the tracks. Ignoring its own evidence, it returned to an argument that man had replaced the sun as the cause current warming patterns. Like many studies, this conclusion was based less on hard data and more on questionable correlations and inaccurate modeling techniques.

The inconvertible fact, here is that even NASA's own study acknowledges that solar variation has caused climate change in the past.

 

And even the study's members, mostly ardent supports of AGW (anthropogenic global warming) theory, acknowledge that the sun may play a significant role in future climate changes.

 

 

400 Years of Sunspot Observations

Past studies have shown that sunspot numbers correspond to warming or cooling trends. The twentieth century has featured heightened activity, indicating a warming trend.

 

 

Solar activity has shown a major spike in the twentieth century, corresponding to global warming. This cyclic variation was acknowledged by a recent NASA study, which reviewed a great deal of past climate data.

 



 




 




NASA Study Shows Sun Responsible for Planet Warming

From DailyTech, we have still more evidence that any warming occurring on planet earth is coming from natural sources and is cyclic in nature - NOT from the evil capitalism that Al Gore, the UN politicians at the IPCC (Intergovernmental Panel on Climate Change) and other socialists love to blame.

From the article:

Now, a new research report from a surprising source may help to lay this skepticism to rest. A study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate data over the past century has concluded that solar variation has made a significant impact on the Earth’s climate.

 

The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution.

Past research has shown that the sun goes through eleven year cycles. At the cycle’s peak, solar activity occurring near sunspots is particularly intense, basking the Earth in solar heat.

 

According to Robert Cahalan, a climatologist at the Goddard Space Flight Center,

“Right now, we are in between major ice ages, in a period that has been called the Holocene.”

If our media, culture and a large portion of the “scientific” community were really honest, it would be the worshippers of the religion of anthropogenic global warming who are called “skeptics,” wouldn’t it?

Because it is those pushing this silly theory that our puny SUVs and power plants are causing earth to warm up when the most obvious source of heat hangs over their head every single day.

AGW simply doesn’t pass the smell test. Nor does it line up with the objective data.


As this graph shows, solar activity has been cyclic in nature going back hundreds of years.

 

 

Solar activity is also increasing, and we are coming out of the “Little Ice Age” of just a few hundred years ago.

 

Of course the planet is warming – we’re coming out of a cold spell! The Maunder Minimum period of diminished solar activity coincided with the Little Ice Age when Europe and North America experienced bitterly cold winters.

About 1,000 years ago, Greenland was warm enough (below video) for the Vikings to colonize and grow vineyards. Today Greenland is almost entirely covered in ice.

 

Tell me:

  • Is the earth warmer today than it was 1,000 years ago?

  • Did they have SUVs and coal power plants in the days of the Vikings?

This isn’t tough to figure out, people.

 

 

 

Unstoppable Solar Cycles

The Real Story of Greenland

 

 

 

 


 

The only thing tough about the global warming debate is trying to get the facts to match the socialist agenda of the AGW proponents. Try as they might, they just can’t do it, and more and more people are starting to see that.

Things like cyclic solar data, warming occurring on other planets such as Mars and Jupiter just don’t line up with the suppositions of the AGW worshippers.

 

They craft all manner of complex calculations and “what ifs,” but in the end the best they can do is say things like,

“Well, we can’t prove it now, but by the time we can, it’ll be too late.”

And we’re supposed to watch our electric bills go up 40% and see our economy devastated on what-ifs and a bunch of garbage that not only doesn’t match the evidence but doesn’t even pass the smell test?

I’m not as gullible as these shysters seem to think I am, and I don’t believe most of the American people are either.
