1. Check the Temperature Trends and Data.

THERE HAS NOW BEEN NO NET WARMING SINCE 1997 -15 YEARS WITH CO2 RISING 8.5% WITH NO GLOBAL TEMPERATURE INCREASE. SINCE 2003 THE TREND IS NEGATIVE.

ftp://ftp.ncdc.noaa.gov/pub/data/anomalies/monthly.ocean.90S.90N.df_1901-2000mean.dat Because of the Urban Heat Island effect ,the built in local variability of the NH land data and the thermal inertia of the oceans, Sea Surface Temperatures are the best measure of global temperature trends. These show that the global warming trend ended in about 2003.To check the past years go toand for monthly updates go to.

The 2012 average NCDC SST anomaly thru Sept was .4438 versus the 1997 annual anomaly of .4575.

The peak anomaly was .5207 in 2003.





2. Check the current phase of the Pacific Decadal Oscillation . An excellent site for reviewing all the basic temperature data is http://www.climate4you.com/

Here is a plot and suggested projection based on the Hadley SST3 from Tallbloke.

(See: http://tallbloke.wordpress.com/2012/10/23/the-carbon-flame-war-final-comment/ ) He says “I have put together a simple model which replicates sea surface temperature (which drives global lower troposphere temperature and surface temperatures a few months later). The correlation between my model and the SST is R^2=0.874 from 1876 FOR MONTHLY DATA.” The model is shown with predictions to 2050 (blue) along with the HADsst3 (red).



http://myweb.wwu.edu/dbunny/pdfs/aleo-easterbrook_ch5Relationship-multidecadal-global-temps-to-oceanic-oscillations.pdf I included Fig 2 because an approximate 60 year cycle is obvious by inspection and this coincides well with the 30 year +/- positive (warm) and 30year +/ negative (cold) phases of the Pacific Decadal Oscillation. Figure 2 shows warming from about 1910 - 1940-45 , cooling from then to about 1975 -.warming to about 2003-5 and cooling since then. Total warming during the 20th century was about 0.8 degrees C.

IT IS CLEAR THAT WE ARE IN THE EARLY STAGES OF A THIRTY YEAR NEGATIVE (COOLING ) PDO CYCLE.

3. Check Solar Activity – where are we at? The major ice age climate cycles are controlled by the sun – earth orbital eccentricity,and the earth’s obliquity and precession. These cycles are approximately 100,000, 41,000 and 21000 years in length respectively and are well documented in the ice core and geological record. It is useful to keep in mind that the warmest temperatures in the current interglacial occurred about 7500+/- years ago and the GENERAL TREND IS NOW A COOLING TOWARDS THE NEXT ICE AGE. Fig 4 http://colli239.fts.educ.msu.edu/1999/07/11/vostok-1999/ These long term cycles are modulated by quasi cyclic trends in solar activity which may be decadal ,centennial or millennial in length.Of particular interest in deciding where we are with regard to the solar cycles is the approximately 1000 +/- year cycle which produced succesively the Roman Warm Period, the Dark Ages,the Medieval Warm Period, the Little Ice Age and the recent 20th century warming.

NOTE – A REASONABLE CASE CAN BE MADE THAT THE WARMING PEAKS OF A 60 YEAR PDO CYCLE AND THE 1000 YEAR SOLAR CYCLE COINCIDED AT 2000 +/- AND WE ARE LIKELY ON THE COOLING SLOPE OF BOTH.

The clearest empirical measure of solar activity is the solar magnetic field strength. On an empirical basis Livingston and Penn have shown that the decline in solar magnetic field strength suggests that sunspots could disappear by about 2015 signalling THE START OF A NEW MAUNDER MINIMUM WITH SIGNIFICANT COOLING.

Ongoing sea temperature readings suggest that global heat content has stabilised over the past 15 years -- despite an 8.5% rise in atmospheric CO2 levels. Ongoing observations are diverging significantly from James Hansen's IPCC model projections, as seen below. Some observers of climate data are expecting the Earth to pass through at least a 30 year climate cooling period.The apparent "decoupling" of global heat from atmospheric CO2 concentrations -- with the clear divergence of observed temperatures from projected temperatures -- provides mounting evidence for falsification of IPCC climate models.Here is an excerpt from an article by Dr. Norman Page, which uses empirical data to contradict IPCC climate model-based projections (via WUWT ):
