How wxshift.com tries to deceive you about climate change/global warming

Just saw this website today, an alarmists posted a graph from it, showing how much warmer the US has become.  I looked at a few graphs, which it generates, to show you how much your area has warmed.  Would be a great tool, but it only starts from 1970.  Lets see why.
wxshift.com
That looks frightening.  Until you check the actual data, and the adjusted data.

NCDC data

100 year trend show the real story.  Even when the data was adjusted to cool the past.


NCDC adjusted data

February really shows the problem with trying to frighten people there with "how much warmer it has become".


Looks dangerous, how fast winter night time lows are rising.  Until you look at all the data.



Funny how they start the data at 1970, isn't it?

But summer have warmed there, right?  wxshift certainly tells you so.



Lets see if we can show all the data instead.  The brutal summer warming in Alabama, from wxshift.
And, a bigger look at the data for Alabama.

Even with the data adjusted to cool the warmest period, we can see why wxshift is deceptive.

Real science doesn't try to deceive you, nor would an actual scientific person not show all the relevant information.  Science is about discovering what really is going on, and why.  Not trying to sway you or deceive you.

wxshift.com for when you want to try and deceive somebody.

November 2015

What it actually looks like, temperature anomalies




What they want you to think it looks like



What the recent global trend sort of looks like


Or we could use this





What real data shows the trend to be (US data)




Eastern US


Central



Southern



West



And what you will never see on TV

The global February trend


(because the global warming theory predicts winter will be the season with the most warming)

Milder winters from global warming - the New York Times 2014

From the NY Times FEB. 8, 2014

An ironic piece, due to the snow that came in the winter of 2015.

Note the graphic uses only spring snow to try and persuade.

Here's the graph from the source, the Rutgers snow lab


Here's what they don't talk about.  The winter trend.


And the Fall trend.
The scientific observer might note that the fall of 2014 was the greatest snow extent since Rutgers started keeping records.  

Experience has shown the New York Times won't be reporting that story.

Why "xkcd on the Cold Truth About Warming" is wrong

We will proceed in a scientific manner.
Is the xkcd comic true? (reproduced with permission)
Mouse over text: 'You see the same pattern all over. Take Detroit--' 'Hold on. Why do you know all these statistics offhand?' 'Oh, um, no idea. I definitely spend my evenings hanging out with friends, and not curating a REALLY NEAT database of temperature statistics. Because, pshh, who would want to do that, right? Also, snowfall records.'

It's a complicated comic, with multiple claims, and it is used to deflect commentary and concerns by people, who notice when it's really cold. So, is any of it true?

None of the black hatted characters claims are true.  And the source the comic creator used is a biased web site that publishes deceptive "science", and is also wrong on the internet.


Looking at the winter trend for Missouri shows why people complaining about the cold In Missouri (and elsewhere) are not delusional,  While temperature data doesn't show the snow and ice, that data also shows the increase in cold winters.

The Tmin (minimum daily temperature) shows it clearly, colder winters.

Comparing with the Tmax confirms it is a trend

Since trends are sensitive at times to start times, here's the 30 year trend using 2014 as the end date.  (the comic was about Jan 2014)

A 30 year trend is solid evidence for climate trends, 

You can see the areas using the GISS maps, the twent year trend for Jan-Feb makes it obvious.


The trend shows up using Jan-Mar.  

It doesn't just seem like winters are getting colder in some cities, they actually are.  It's why the xkcd comic is wrong.

That's a shame, since I really like his work.

The tale of a weather station, and how BEST messed it up

While all the surface data is adjusted, BEST is an easy target,  Fish in a barrel actually.

Here is the actual data, from GHCN
Location


Dale Enterprises is a quality controlled station with no changes, aside from adding an electronic sensor in 1995, but they kept the old mercury instruments as well.

This is what Watts showed in 2010, about the USHCN adjustments

Here is the current GHCN adjustment, using the BOM tool

Compared to the actual data



And here is what BEST did to the data




Just awful "science" at work there.  Instead of using a quality station to adjust the bad stations, they adjust the good station to match the bad ones.

Here's a nearby bad station moved next to water treatment plant, showing a drastic increase in the trend.






Google maps of water treatment plant where that station rests.

The Dale Enterprise station is just north of there.

BEST and the rest of the data analysis adjusted the good station, not the bad ones.They are wrong, but they probably don't even know it.

Note on the Theory of the Greenhouse

From a blog page by Connolley (no longer available from the original page)  This content is also available here by Spencer.  As well as elsehwere.

XXIV. Note on the Theory of the GreenhouseBy Professor R. W. Wood (Communicated by the Author) 
THERE appears to be a widespread belief that the comparatively high temperature produced within a closed space covered with glass, and exposed to solar radiation, results from a transformation of wave-length, that is, that the heat waves from the sun, which are able to penetrate the glass, fall upon the walls of the enclosure and raise its temperature: the heat energy is re-emitted by the walls in the form of much longer waves, which are unable to penetrate the glass, the greenhouse acting as a radiation trap.
I have always felt some doubt as to whether this action played any very large part in the elevation of temperature. It appeared much more probable that the part played by the glass was the prevention of the escape of the warm air heated by the ground within the enclosure. If we open the doors of a greenhouse on a cold and windy day, the trapping of radiation appears to lose much of its efficacy. As a matter of fact I am of the opinion that a greenhouse made of a glass transparent to waves of every possible length would show a temperature nearly, if not quite, as high as that observed in a glass house. The transparent screen allows the solar radiation to warm the ground, and the ground in turn warms the air, but only the limited amount within the enclosure. In the "open," the ground is continually brought into contact with cold air by convection currents. 
To test the matter I constructed two enclosures of dead black cardboard, one covered with a glass plate, the other with a plate of rock-salt of equal thickness. The bulb of a themometer was inserted in each enclosure and the whole packed in cotton, with the exception of the transparent plates which were exposed. When exposed to sunlight the temperature rose gradually to 65 oC., the enclosure covered with the salt plate keeping a little ahead of the other, owing to the fact that it transmitted the longer waves from the sun, which were stopped by the glass. In order to eliminate this action the sunlight was first passed through a glass plate. 
There was now scarcely a difference of one degree between the temperatures of the two enclosures. The maximum temperature reached was about 55 oC. From what we know about the distribution of energy in the spectrum of the radiation emitted by a body at 55 o, it is clear that the rock-salt plate is capable of transmitting practically all of it, while the glass plate stops it entirely. This shows us that the loss of temperature of the ground by radiation is very small in comparison to the loss by convection, in other words that we gain very little from the circumstance that the radiation is trapped. 
Is it therefore necessary to pay attention to trapped radiation in deducing the temperature of a planet as affected by its atmosphere? The solar rays penetrate the atmosphere, warm the ground which in turn warms the atmosphere by contact and by convection currents. The heat received is thus stored up in the atmosphere, remaining there on account of the very low radiating power of a gas. It seems to me very doubtful if the atmosphere is warmed to any great extent by absorbing the radiation from the ground, even under the most favourable conditions. 
I do not pretent to have gone very deeply into the matter, and publish this note merely to draw attention to the fact that trapped radiation appears to play but a very small part in the actual cases with which we are familiar.

--------------------------------------------------------

Connolley then adds:
Why is his second to last paragraph wrong?

Firstly, note that unlike the experiments described earlier, this paragraph merely expresses his opinion. 
Second, although the troposphere is subject to convection, the stratosphere is not.
Third, in contradiction to his assertion about "the very low radiating power of a gas", the troposphere is largely opaque to infra-red radiation, which is why convection is so important in moving heat up from the surface. Only in the higher (colder) atmosphere where there is less water vapour is the atmosphere simultaneously somewhat, but not totally, transparent to infra-red and thus permits radiation to play a part. 
W. M. Connolley, June 2000.

Here are the results of Spencer doing the experiment, with commentary.

Snow and climate change

Does a warmer world have more snow or less?  This is no idle question.  It might be both.

Temperature and tornadoes

Because of the lack of  winter and early spring tornadoes, I checked the periods with no tornadoes, for the US.  When it's cold there are no tornadoes.

This is due to the lack of warm moist air meeting the cold fronts.  Strong very cold fronts prevent tornadoes from happening.

They also result in a lot more snow.

Does it have to be cold to snow?

This seems like a stupid question, but the importance of the principle is simple.

Yes, it has to be cold to snow.  It does not snow when it's warm.

Extensive post on this coming up.

Milder winter temperatures will decrease heavy snowstorms IPCC 2001


This is true of course.  And colder winters result in more snow.

An example of how GISS is nothing like the NCDC global data

Feb 1963 NCDC global land land mean + 1.27C compare with GISS

Feb 2014 NCDC global land land mean  + .23C - compare with GISS

GISS makes it look like Feb 1963 was much colder than February 2014.  The NCDC global data shows 1963 much warmer for the global land mean.

The two data analysis differ in some significant ways

Looking at 2014 and the other warmest years

This graphic shows the three warmest years, against the highest records, which is a combined figure, using each months warmest anomaly.
Note that for Dec-Jan-Feb and even March the warmest month is not for those three record years.  In fact, for 2014 and 2005 February is very low.   2010 shows a very cool December. 

This is not some obscure point, 2014 is cliamed to be the warmest year on record, yet shows a very cold February anomaly, which matches the trend, globally, of February cooling since 1998 (warmest February anomaly ever)

Here are the GISS global charts for December

January

February
March

Here are the same graphs using just the NH land anomalies.

Dec


Jan

Feb

Mar


February, for both the GISS global mean, as well as the NH mean, shows cooling, which is the exact opposite of what global warming theory predicts, based on an enhanced greenhouse effect.

That this shows up clearly, even with the warmest years, is an important issue, the reason for new theories about how climate is changing.

When Trenberth's claim about extreme weather is a result of  a generally warmer and moister atmosphere is used to explain the much colder winters, and the extreme amounts of snow, it's complete nonsense.  Because the NH winter atmosphere is not warmer.  The data clearly shows this.
