No surprise here. Just more inconvenient results for CO2 broken-record dogmatists.
New paper: GISS temps and solar activity
A recent paper published by the Journal of Atmospheric and Solar Terrestial Physics (74) 2012 87-93 and authored by Souza Echer et al. suggests that solar cycles, to a substantial extent, drive global temperatures, and that likely through amplification mechanisms.
The authors decomposed average air surface temperature series obtained from GISS and sunspot number (Rz) from 1880 – 2005 to see if a correlation could be found. They performed a cross correlation analysis between band-passed filtered data around 11-year and 22 years.
Although the authors did not find a strong correlation with the 11-year solar cycle, they found a “very significant correlation” in the 22-year Hale cycle band. The abstract states:
A very significant correlation (Rz 0.57 to 0.80) is found in the 22 yr solar Hale cycle band (16–32 years ) with lags from zero to four years between latitudinal averages air surface temperature and Rz. Therefore it seems that the 22 yr magnetic field solar cycle might have a higher effect on Earth’s climate than solar variations related to the 11-yr sunspot cycle.”
Well then, can we not assume that if the 22-year cycles have an impact, also the 78-year, 210-year, and 1000-year solar activity cycles must have a “significant correlation” with the earth’s climate too? Already there are dozens of proxy records showing that this is precisely the case.
Recall that the CO2 warmists in their half-baked models stubbornly keep focusing only on total solar irradiance (TSI), which itself varies only about 0.1% over an 11-year cycle (and thus by itself is no real climate driver) and ignore all the other amplification mechanisms. Well, the results of this study, as do dozens of others studies, show you can’t do that. Like it or not – the sun is a real player. Eventually the CO2 warmists will have to admit this, as anyone with even just an inkling of intuition would do.
New paper: investigating the cosmic ray link
Obviously there are others who feel the same way when it comes to the role of the sun on the earth’s climate. Another paper just published at the same journal shows that other scientists are hot on the sun’s trail. Here Magee and Kavic in their paper titled: Probing the climatological impact of a cosmic ray–cloud connection through low-frequency radio observations suspect a solar mechanism and so propose a method of observation. In the abstract they write:
…in order to establish whether or not such a relationship exists, measurements of short-timescale solar events, individual cosmic ray events, and spatially correlated cloud parameters could be of great significance. Here we propose such a comparison using observations from a pair of radio telescopes arrays,the Long Wavelength Array (LWA) and the Eight-meter-wavelength Transient Array (ETA). These low-frequency radio arrays have a unique ability to simultaneously conduct solar, ionospheric and cosmic rays observations and are thus ideal for such a comparison.”
The direction of climate science and investigation is clear. The real discoveries will involve unraveling the solar mechanisms, and not baking simplistic, straight-line CO2-temperature models. With each new study, the CO2 warmists look more and more like broken records that keep repeating: CO2…CO2…CO2…CO2…
Obviously some scientists just aren’t clever enough to snap out of it.
