Question:

Are Climatologists Now Believing the Sun Has A Major Role In Climate, and We Should Prepare for Cooling Now?

"The sun has reached a milestone not seen for nearly 100 years: an entire month has passed without a single visible sunspot being noted.

The event is significant as many climatologists now believe solar magnetic activity – which determines the number of sunspots -- is an influencing factor for climate on earth."

"In the past 1000 years, three previous such events -- the Dalton, Maunder, and Spörer Minimums, have all led to rapid cooling. One was large enough to be called a "mini ice age". "

"Meteorologist Anthony Watts, who runs a climate data auditing site, tells DailyTech the sunspot numbers are another indication the "sun's dynamo" is idling. According to Watts, the effect of sunspots on TSI (total solar irradiance) is negligible, but the reduction in the solar magnetosphere affects cloud formation here on Earth, which in turn modulates climate.

This theory was originally proposed by physicist Henrik Svensmark, who has published a number of scientific papers on the subject. Last year Svensmark's "SKY" experiment claimed to have proven that galactic cosmic rays -- which the sun's magnetic field partially shields the Earth from -- increase the formation of molecular clusters that promote cloud growth. Svensmark, who recently published a book on the theory, says the relationship is a larger factor in climate change than greenhouse gases."

"What is incontrovertible, though, is that ice ages have occurred before. And no scientist, even the most skeptical, is prepared to say it won't happen again."

Does this vindicate those who always knew the climate was more affected by the Sun than your family sedan?

Is it time to give up this "Man Made" Global Warming BS?

  1. climatoligist have slowly been converting to this train of thought over the last few year and based on their projections based on solar activity we could be facing a cooling period for at least a decade or more, this may or may not happen but the only people who predicted the current cooling we are experiancing where those who based their projections on solar actvitity.

    Astrologists have kept records of solar activity for hundreds of years so we have a very good record of historical solar activity for drawing a comparision.

    When solar activity is compared to global temp reconstructions based on proxy data a link is clear and that it is driven by at least part solar energy. The statistical correllation is better than that of temeperature and co2 over the last 100 years.

    Also climate models that predict the weather based on solar cycles have been shown to be more accurate for long term weather predictions.

    There is definetly evidence to show that solar variation along with other factors drive the climate and explains the previous cold and warm periods.

    The following document gives reference to many peer reviwed papers siting solar acitivty as a key driver of the climate system:

  2. Solar forcing has more evidence supporting it than Co2 forcing , so ...

    Yes !

  3. This graph, from your link, does NOT correspond to temperature graphs.

    Your link...

    1. Your links show 1998, 2005 and 2007 solar activity was unremarkable to low, yet annual means are .57, .62 and .57 (C), respectively. No correlation!

    2. 1991 and 1993 show spikes in solar activity, but their respective annual means are .35 and .14 (C) respectively. No correlation!

    Climatologists have always understood the sun has a role in climate change. You never got the memo, or conveniently decided to ignore it so as to perpetuate your myth.  

  4. No, nobody ever thought about looking at the sun before until some right wing bloggers pointed it out.  Oh wait a minute, yes they did and have published graphs of the sun's activity.

  5. There does not seem to be any correlation between CO2 emissions and global warming. None! Something else must be responsible for climate fluctuations which have occurred for the last 4 billion or so years.

    Solar activity has always been suspect but as things go, there are probably a number of factors at play and CO2 increases do not seem to precede global warming!  

  6. Put this and the PDO - Pacific Decadal Oscillation - together and we will be in for a major cooling off period. Then who will be in denial?

    I tell people I've read up on this stuff and had come to a controversial conclusion and they thought I was crazy. I guess only time will tell who's being crazy them or me.

  7. First we have to figure out what exactly is a "mini ice age". If there's mini ice ages then that would obviously mean there are larger ice ages too.

  8. Well, I have experienced some really hot days here lately in the U.S.A. and until I start feeling real cold in July and August I am going to ignore the "Sunspot Theory". Global warming I can see. The Alaskan glaciers are melting fast. They could use a sunspot ice age right about now. In the meantime, we can't control the sun, but collectively we can choose to reduce the damage that our existence causes to the environment. You can choose otherwise. Each of us must live by our own convictions.

  9. This is all very theoretical.  And if it says that the sun is cooling and yet the Earth is  warming, then I'm not sure how this vindicates global warming deniers.

      

  10. I don't know what climatologists believe. My home town is about 10 degrees F below the average for August. It's been quite cool for summer. It will be interesting to see what happens in the next year or two. Farmers home almanac predicts a colder then normal winter. National Weather service predicts about the same. Higher then normal temps.

  11. I am totally with you on this one. Everyone is worried about global warming but in fact, the opposite is happening, The sun has everything to do with our climate, and what you are saying is very interesting considering the experiment that was done right after 9-11 when they stopped all airplane flights. The pollution put out by airplanes is blocking the suns rays that cause water to evaporate, which in turn causes less rain leading to drought.

    Either way, man made pollution is not helping anything.
