Most Revealing Chart Part 1 Computer Forecasts versus Actual Temperature Measurements.


The graph below is probably the most revealing of all the graphs used when discussing man-made global warming.  John Christy presented it to a US Congressional hearing in 2017.  The graph’s X axis shows years and the Y axis is global atmospheric temperature  anomalys in  degrees Centigrade.   (“Anomaly” degrees, is the measurement of the change in temperature rather that the actual temperature.  The actual temperature is somewhere  around 15C.  The exact temperature can be contentious.  So the anomaly is usually charted.)

The red line is the “average of 102 IPCC CMIP-5 climate model runs.  The man-made global warming theory doesn’t have one model.   They had 102 models all churning out forecasts of the future global temperature. All with different assumptions of what will the future look like.  All of them show rising temperature based  primarily the  amount of Carbon Dioxide (CO2) in the atmosphere.  The forecast spread is all over the place based upon a number of other assumed forces.  Christy averaged the forecasts and that is  source of the red line.

Then Christy added the atmospheric  temperatures that were  MEASURED,  by satellites and weather balloons.

So, stating the obvious, we have actual measured temperatures versus forecast temperatures. One can note that over the time, the separation between actual and forecast has gotten greater and appears that trend will continue

 

 

These forecast high temperatures are what propels the catastrophic man-made global forecasts of sky high sea levels, melting glaciers, mass migrations,  mass extinction of species, terrifying  severe weather, and deadly heat.  The media revels in these forecast disasters and gives them top billing.  But why would you believe this will be the Earth’s future?   Surely if everyone knew this or have just learned it, why would they be persuaded to foist these irrational conclusions upon us?

You may be thinking that only one model would be necessary if they really could forecast average global temperatures.

Does The Green House Gas Effect Really Exist?–Part 2


The previous posting,  “Does the Greenhouse gas effect really exist–Part 1”,  looked at measured radiation of longwave infrared (IR)  that demonstrated the greenhouse gas effect.

There is another way to demonstrate the  greenhouse gas effect using the SURFRAD data.  I have selected SURFRAD data for the year 2016 for the Sioux Falls, South Dakota and Desert Rock, Nevada sites

Some thoughts about the following charts 1B and 3B.  These charts plot  the radiation data—both solar short wave and the Earth’s longwave IR plus the net Solar and net longwave IR.

Charts 2B and 4B show air temperature, wind speed, relative humidity and albedo.  These data are not used in the analysis but might prove valuable to someone interested in deriving a better understanding of the energy balance.

Different from the earlier chart in Part 1 which showed a 24 hour continuous plot of data, the following 4 charts are the daily data in a given month combined and  the mean extracted for each data set.

Does The Green House Gas Effect Really Exist?–Part 1


Does one have to deny that the so-called green house gases (GHG)s have an effect on global temperatures to be a skeptic?  Many of the big-league skeptics believe that the GHGs do play a part in global temperature.  So maybe not.

The following is a quote from Climate Change Reconsidered II** :

“ As carbon dioxide concentrations increase so too does the intensity of back radiation at the surface across the active wavebands of CO2, and because this radiation emanates from a lower and warmer layer of the atmosphere, the magnitude of the back radiation increases. Consequently, the net infrared radiation emanating from the surface is reduced, causing a rise in temperature that generates increased heat exchange and evaporation. This surface warming also contributes to an increase in convective instability”.

So, hold on and let me explain why I believe this.

First, a look at the big picture.   The Sun’s surface is somewhere about 5500 C.  Radiation goes out in all directions with some of it directed toward Earth.  This is Earth’s principal source of energy.  This radiation travels 93 million miles in about 8 minutes to reach Earth.  It loses much of its strength in the journey, but at the top of our atmosphere, its strength is nominally 1365 watts per square meter.  The Sun’s radiation mainly consists of photons of visible light, ultraviolet and infrared.  The full force of the Sun’s radiation seldom reaches the Earth surface because of clouds, reflection off snow and ice, scattering in the atmosphere for example and the angle that the Sun’s rays strike the surface.  Further complicating this topic is the fact on average, the Sun only shines on any place on Earth for more than 12 hours per day.

Many charts showing the Earth’s average energy budget use 340 w/m²  because when you factor in the length of the day and the spherical geometry of the Earth the effect is about ¼ the energy at the top of the atmosphere at noon.  While the Energy budget charts are useful, I believe they get in the way of understanding the GHG effect.  So, the following will uses actual measured radiation data and not the hypothetical 340w/m².

To get an idea of what happens at the surface, lets take a look at the data collected by the Surface Radiation Project. The Surface Radiation Budget Network (SURFRAD) was established in 1993 through the support of NOAA’s Office of Global Programs. The SURFRAD mission is clear:

“its primary objective is to support climate research with accurate, continuous, long-term measurements of the surface radiation budget over the United States”. 

SURFRAD currently has 7 operating stations.  These stations are very well equipped. They can measure upwelling and downwelling solar, upwelling and downwelling IR, temperature, RH, wind speed, cloud cover, UVb  and several others.   The SURFRAD website allows you to make charts of the collected day.  For starters I have plotted some data from the Desert Rock, Nevada SURFRAD site.

Climate Model Forecast Temperatures Are Too High Study Says


Look at these charts that show correlation. 

So, there you are.     You have seen it all now.  See how easy It is to make correlations.

BUT WAIT, I forgot to show you the most important one of all.   It’s shows how actual measured global temperatures correlates with the global temperature forecasts made by the climate models that the catastrophic man-made global warming (CMNGW) scientists use.

Large Spike in Cycle 24 Sunspots and F10.7 Solar Flux


Solar Cycle 24 still has some surprises.   Both the NOAA  Sunspot count and F10.7 solar flux spiked.  The right hand side of the chart below, from Solen  shows the Sunspot count to have peaked at about 120 and the F10.7 solar flux above  130.  Sunspot count and Solar Flux usually act in unison. Dr Svalgaard says that F10,7 is a more reliable indicator of solar activity than Sunspots

Last major update issued on September 6, 2017 at 05:00 UT. Update posted at 13:50 UT

The generally accepted  way to portray  Sunspots is using a smoothed count from Sunspot Index and Long-term Solar Observations (SILSO). SILSO data is provided by the  Royal Observatory of Belgium, in Brussels. That number is charted below as Ri smoothed. ” Smoothed” is the process of averaging the daily numbers over some period of time. Silso number uses a formula* (see below) that incorporates some 13 months of monthly data.

In the chart  below, Ri is the total monthly Sunspots that were occasioned by the solar polar fields,  north (Rnorth ) and south (Rsouth).

Spikes in activity are not  uncommon as can be seen in the above chart which chronicles Solar Cycle 24 from its beginning to the current time.  I am still surprised at this late date.

*The Silso formula:

The smoothed count is a 13-month averaged sunspot count using this Belgium’s formula:
Rs= (0.5 Rm-6 + Rm-5 + Rm-4 + Rm-3 + Rm-2 + Rm-1 + Rm + Rm+1 + Rm+2 + Rm+3 + Rm+4 + Rm+5 + 0.5 Rm+6 ) / 12
Rs = smoothed monthly sunspot count
Rm = One month’s actual sunspot count
The “-6” through “+6” appended to each Rm is the number of months before or after the month whose smoothed count is being calculated. The beginning and ending months in the formula are only given half the value of the others.*

Harvey Not Caused By Man-made Global Warming


Many of the catastrophic warming brigade are shouting that hurricane Harvey is the fruit of global warming tree.  The media, the other branch of the Democrat Party, are saying the same thing.   Joe D’Aleo’s marvelous website, IceCap, provides a chart that will show open minded people that these big hurricanes have been going on for quite a while.   Well before the supposed start of the CO2 caused global warming.   The following chart shows the history of the biggest hurricanes that have hit the US since 1851:

Note that Katrina and Sandy are not on the list.  Hurricanes can be destructive even if they are not 4 or 5 category storms.  Sandy perhaps not even a category 1 hurricane when it made landfall, caused considerable damage from the storm surge.  Storm surge occurs when a major storm pushes water on  to the shore  at levels well above normal.

Further, how do you account for the fact that the last  hurricane of category 3 or larger to make landfall on the US was 12 years ago.   I guess that means there has been no warming during those 12 years.   But wait,  how can that be because the warmers keep telling me that the “hottest ever years” are now.
