Summary:

It has been shown above that low altitude cloud cover closely follows cosmic ray flux; that the galactic cosmic ray flux has the periodicities of the glacial/interglacial cycles; that a decrease in galactic cosmic ray flux was coincident with Termination II [the warming that initiated the Eemian, the last interglacial] ; and that the most likely initiator for Termination II was a consequent decrease in Earth’s albedo.

The temperature of past interglacials was higher than today most likely as a consequence of a lower global albedo due to a decrease in galactic cosmic ray flux reaching the Earth’s atmosphere. In addition, the galactic cosmic ray intensity exhibits a 100 kyr periodicity over the last 200 kyr that is in phase with the glacial terminations of this period. Carbon dioxide appears to play a very limited role in setting interglacial temperature.

Yesterday I posted two YouTubes from Piers Corbyn. There was so much highlighted in the first video I think the second video may have passed a few of you by. At the end of the second video, from about the 4 minute mark, you will come across a treasure trove of information concerning the effect of solar particles on the Earth's Thermosphere. This is worth a mention in it's own right!

Please take time out to see this 2nd video, as it explains why there are changes to our climate from solar activity and NOT CO2, and what Piers thinks happens when the Sun is less active with the effect of a cooler Thermosphere. His theory is far more credible then the current IPCC suggestion of global warming, as it points to global cooling being the result of a less active Sun.

Scientists dismiss claims of runaway man-made global warming by Kirk Myers, Examiner.com

Several researchers are claiming in a study published last week that rising greenhouse emissions will raise global temperatures by 6.7 to 8.0 degrees by 2100, even if the earth's climate enters another “Little Ice Age.”

Huh?

In their paper published in the journal of Geophysical Research Letters, Georg Fuelner and Stefan Ramstorf of the Potsdam Institute claim that a long-lasting decline in solar activity – similar to the period from 1300 to 1850 known as the Little Ice Age – would cut only 0.5 degrees from the projected rise in global temperatures this century.

Give Fuelner and Ramstorf credit for not going out on a limb with their prediction. Their forecasting prowess covers only the next 90 years. (A few recently humbled meteorologists at the MET Office in Britain would kill to have such predictive powers.)

Where does such nonsense come from?

According to the anthropogenic global warming (AGW) crowd (e.g., government-paid shills like NASA’s James Hansen, “Hockey Stick” Penn State Professor Michael Mann, and disgraced former Climate Research Unit Director Phil Jones), CO2 emissions from burning fossil fuels are being trapped in the atmosphere where they act as a temperature-forcing agent. As CO2 levels continue to rise, the planet will eventually face runaway global warming.

However, there is a problem with their “catastrophic climate change” theory: hard, empirical evidence does not exist to support it.

Earth Approaching Sunspot Records, Corey Jones talks to Charlie Perry, a research hydrologist with the U.S. Geological Survey in Lawrence

The average person may not associate coolness with the sun. The sun releases energy through deep nuclear fusion reactions in its core and has surface temperatures as hot as 10,000 degrees Fahrenheit, according to NASA’s Web site.

Not cool at all. But the sun’s recent activity, or lack thereof, may be linked to the pleasant summer temperatures the midwest has enjoyed this year, said Charlie Perry, a research hydrologist with the U.S. Geological Survey in Lawrence. The sun is at a low point of a deep solar minimum in which there are little to no sunspots on its surface. In July through August, 51 consecutive days passed without a spot, one day short of tying the record of 52 days from the early 1900s.

As of Sept. 15, the current solar minimum ranks third all-time in the amount of spotless days with 717 since 2004. There have been 206 spotless days in 2009, which is 14th all-time. But there are still more than 100 days left in the year, and Perry expects that number to climb. Perry, who studies sunspots and solar activity in his spare time, received an undergraduate degree in physics at Kansas State University and a Ph.D in physics and astronomy at The University of Kansas. He also has spent time as a meteorologist.

December sunspots on the rise by Anthony Watts

The dark line is a linear least-squares fit to the data. If the trend continues exactly as shown (prediction: it won’t), sunspots will become a non-stop daily occurance no later than February 2011. Blank suns would cease and solar minimum would be over.

If the past two years have taught us anything, however, it is that the sun can be tricky and unpredictable.

Sun & Cycles Heat Up Ice Age Interglacials by Doug L. Hoffman

Image AttachmentSince the Mid-Brunhes Event, around 430,000 years ago, interglacial periods have grown warmer and their CO2 levels higher. Research confirms that Croll and Milankovitch were right: Earth's orbital cycles seem to be the cause of these documented cases of true global warming, with CO2 playing a supporting role, not the lead. Many of the catastrophic events warned of by climate change alarmists turn out to be well within the range of natural variation. Moreover, new findings indicate that the effects of the cycle induced changes, through their impact on the environment in the Southern Hemisphere, are not correctly accounted for in the IPCC models.

One of the big questions in climate science comes from studying recent interglacial periods—those relatively warm periods between bouts of ice age glaciation. It has been known for some time, that average temperatures during recent interglacials were warmer than during older ones. Writing in the April, 2010, edition of Nature Geoscience, Q. Z. Yin and A. Berger propose an answer as to why the amplitude (i.e. warming) of the glacial interglacial cycles increased significantly after the Mid-Brunhes Event (MBE) with cooler interglacials before the MBE than after. In their paper, entitled “Insolation and CO2 contribution to the interglacial climate before and after the Mid-Brunhes Event,” they describe their work as follows:

In parallel to the reconstruction of palaeoclimate based on proxy records, climate models are used to better understand past climate behaviour. In particular, efforts have been made over the past decade on modelling the most recent interglacials, namely the Holocene, the Eemian and the past five interglacials. Here, we focus on the forcing and global response of the climate system at the interglacial peaks of the past 800 kyr, using snapshot simulations to try to understand the difference between the post-MBE and the pre-MBE interglacials. The model used is LOVECLIM, with the atmosphere, ocean, sea ice and vegetation components interactively coupled and the ice sheets kept as today.

How Well Do Scientists Understand How Changes in Earth's Orbit Affect Long-Term Natural Climate Trends? ScienceDaily.com

ScienceDaily (Feb. 5, 2010) — The notion that scientists understand how changes in Earth's orbit affect climate well enough for estimating long-term natural climate trends that underlie any anthropogenic climate change is challenged by findings just published.

The new research was conducted by a team led by Professor Eelco Rohling of the University of Southampton's School of Ocean and Earth Science hosted at the National Oceanography Centre, Southampton.

"Understanding how climate has responded to past change should help reveal how human activities may have affected, or will affect, Earth's climate. One approach for this is to study past interglacials, the warm periods between glacial periods within an ice age," said Rohling.

He continued: "Note that we have here focused on the long-term natural climate trends that are related to changes in Earth's orbit around the Sun. Our study is therefore relevant to the long-term climate future, and not so much for the next decades or century."

Oleg Toumilovitch "spotted" it on July 31st rising over Blairgowrie, South Africa

A sunspot directly related to a series of massive solar storms was captured in this photo of sunrise over South Africa on July 31st. The next day, August 1st displayed a solar tsunami, C3 class solar flare. That is as strong as they come. According to Spaceweather, this included multiple filaments of magnetism lifting off the stellar surface, large-scale shaking of the solar corona, radio bursts, a coronal mass ejection and more. Below see video of the actual storm. Another video at the bottom of this post discusses the forecast for a dramatic increase in activity up through 2012.

This was on the earth facing side of the sun, and has been sent directly towards earth. The results could be a beautiful display of the northern lights tonight (August 3rd), and Wednesday night (August 4th). But it can also lead to problems with satellites. Many satellites monitoring Earth and space are followed locally at NASA Goddard in Greenbelt, Maryland.
