question

What modulates our Sun? The majority of science work on the principle that the Sun is self modulating and each solar cycle is a product of a random number generator. There are others that suspect the Sun is modulated by the planets with a special emphasis on Uranus & Neptune. Thanks to Carl Smith who has recently left us we have new knowledge that significantly adds to Jose, Landscheidt & Charvàtovà's work.

UAH Satellite figures in for December

 

From Roy Spencer:

"The global-average lower tropospheric temperature anomaly fell back to the October level of +0.28 deg. C in December. The tropics continue warm from El Nino conditions there, while the NH and SH extratropics anomalies cooled from last month. While the large amount of year-to-year variability in global temperatures seen in the above plot makes it difficult to provide meaningful statements about long-term temperature trends in the context of global warming, the running 25-month average suggests there has been no net warming in the last 11 years or so.

[NOTE: These satellite measurements are not calibrated to surface thermometer data in any way, but instead use on-board redundant precision platinum resistance thermometers carried on the satellite radiometers.]"

 

Is this the real start of the global cooling? Is what we have experienced since 2000 just a taste of what the future holds, this is very possible if we look at the surrounding environment. We are still in a deep solar minimum that will respond slowly but the size of the heliosphere is cast for the next 12 months, the current el nino doesn't have a lot of punch and will decline further after January, plus we are now beginning our journey away from the warmest/closest approach to our Sun.  The oceans major pools are in their cool zones and the solar wind is still at the lowest value since records began, the cards are stacked against a man made rise in global temperatures.

The world is talking about the unusual cold extremes in the northern hemisphere as describribed in our local media http://www.theaustralian.com.au/news/world/freezing-temperatures-massive-snowfalls-wreak-havoc-around-the-world/story-e6frg6so-1225816337510....perhaps it will get even worse which may start to focus our attention on the real deal.

Tomorrow I will have a story on the Extreme UV measurements taken from the SOHO satellite. UV is another big player in our Sun climate link.

Why a 25 month moving average interval for global temperature?

I noticed that Spencer's choice of a 25-month moving average of global temperatures from Jan, 1979 to present seems to be a good one, but wondered - is 25 months a better choice than 24 months?  In the process of investigating, I found this interesting paper:
 
Apparently the answer to my question is yes.  Why?  Because Solar Activity drives climate change.

Informative post about the

Informative post about the UAH satellite. Great to see clearly the satellite measurements from the surface thermometer data . Speaking of satellite I read from this article UARS satellite pieces have 1 in 3,200 chance of hitting Earth that the satellite arrived at what NASA called "the end of a productive scientific life" a full six years ago. UARS is expected to come back to Earth soon. By Saturday, the satellite will re-enter the atmosphere. The Upper Atmosphere Research Satellite, was in Earth's orbit for 20 years. In 2005, NASA efficiently decommissioned the satellite. The instrumentation on the satellite was still working, but only hardly. UARS is expected to come back to Earth soon. By Saturday, the satellite will re-enter the atmosphere.

Many thanks go to Carl's brother Dave for providing the Domain, Server and Software.
