Most Revealing Chart Part 2–Failed Warmer Predictions


 

The previous posting shows that the warmer’s forecast “average global temperature” is way off from the actual measurements.  These alarmists use that erroneous forecast as the basis for their pronouncement of future global catastrophes that will come about if we don’t join their quest to remove CO2 emissions and switch to renewable energy.   

The alarmist’s forecasts of catastrophes get maximum coverage in the media.  It is obvious that the media never checks to see if the previous forecast have proven correct. And the following will demonstrate that the media never ever question an alarmist prediction and never ever goes back to check out the previous predictions.

There all kinds of alarmist’s forecasts, some of which I covered in an earlier posting titled” CAGW PREDICTIONS—ZOMBIE AND OTHER”. Almost all of them are embarrassingly wrong.   I encourage you to click on the link and have some good laughs.

The awful forecasts that follow are from scientists, science organizations and many from the Intergovernmental Panel on Climate Change (IPCC)— a UN organization. This assembly of failure was posted by Javier on The Blog WattsUpWithThat with an intro by Andy May.  Andy takes a little liberty with Javier’s posting by adding on a section that highlights obvious predictions that the alarmists should have made.

An outline of the failed predictions are as follows:

·        Warming rate predictions

·        Temperature predictions

·        Winter predictions

·        Snow predictions

·        Precipitation predictions

·        Extreme weather predictions

·        Wildfire predictions

·        Rotation of the Earth predictions

·        Arctic sea predictions

·        Polar bear predictions

·        Glacier predictions

·        Sea level predictions

·        Sinking nation predictions

·        Climate refugee predictions

·        Climate change predictions

–and Andy May’s failure to predict list—

·        Greener planet

·        Increase in forest biomass

·        Carbon sinks increase

·        Slowdown in warming

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.

President Trump Dumps Alarmist Panel-Draining The Swamp Continues


The climate alarmists tell the public that the sea level is going rise 7 to 15 feet by the end of this century.  The crops are going to fail.  There will be mass extinctions.  The extent of the horrors awaiting us in the future are almost unlimited.  The basis for all these catastrophes is the predicted rise in temperature based upon the computer models they have programed. For example, the sea level rise is predicated on a rise of temperature in the range of 4 to 7° C  or greater by the year 2100.  Without the big rise in global temperature, all these supposed disasters will not come to pass.

These computers have been forecasting temperature for many years.  How are they doing?  If a company had their operations run by these computers, they would be out of business by now.  Look at some of the recent revelations. The New American posted “Top Climate Alarmist: Computer Models Wrong, Skeptics Right on “Pause”.  From that posting we get this:

“Count on the Fake News media to ignore a huge admission by a Climategate scientist that there has been no measurable global warming over the past 20 years — something he has previously vociferously denied. The admission by Dr. Benjamin Santer, a top global-warming alarmist, should have made headlines — but, of course it didn’t.

Greenland Ice Loss Has Contributed A Negligble 1.5cm To Sea Level Since 1900


 This is a reblog of a posting on No Tricks Zone.
 The topic is how the warmers and their cohorts in the media exaggerate the effect of melting glaciers  are having on sea level rise.  This posting is one more confirmation that the US media do not understand the metric numbers.

Since 1993, Greenland’s Ice Sheet Melt Has Added Just 0.39 Of A Centimeter To Global Sea Levels

Exposing ‘Staggering’ Ice Sheet Melt Deceptions

In recent months, two new papers published in The Cryosphere have provided a condensed summary of the ice-melt and sea-level-rise consequences of global warming for the Arctic region.

1.  Between 1900 and 2010, the Greenland Ice Sheet (GIS) has melted so extensively and so rapidly that the GIS ice-melt contribution to global sea level rise has amounted to 1.5 centimeters for the entire 110-year period.   One-and-a-half centimeters.  That’s 0.59 of an inch!

2. It gets worse.  Between 1993 and 2010, the contribution to global sea level rise has been a disturbing 0.39 of a centimeter.  Almost 4/10ths of a centimeter.  That’s 0.15 of an inch!


Leeson et al, 2017

Melt water from the Greenland ice sheet contributed 1.7–6.12 mm [median 3.9 mm, or 0.39 of a centimeter] to global sea level between 1993 and 2010


Fettweis et al ., 2017

SMB [surface mass balance, Greenland Ice Sheet] during the 1920–1930 warm period over Greenland was comparable to the SMB of the 2000s, due to both higher melt and lower precipitation than normal.”

“Finally, with respect to the 1961–1990 period, the integrated contribution of the GrIS SMB [Greenland Ice Sheet Surface Mass Balance] anomalies over 1900–2010 is a sea level rise of about 15 ± 5 mm [1.5 centimeters], with a null contribution from the 1940s to the 2000s


Breakdown: 1900-2010 GIS Sea Level Rise Contribution

1920s-1930s: GIS contribution to sea level rise: 1.1 cm

1993-2010: GIS contribution to sea level rise: 0.39 cm

1940s-2000s: a null contribution” [to sea level rise]


Washington Post Peddles Alarmism With Deceptive ‘Trillion Tons’ Of Lost Ice Pronouncements


It’s scary to learn that the Greenland Ice Sheet has lost a “staggering” 9 trillion tons of ice since 1900.

It’s not scary to learn that 9 trillion tons of ice losses actually amounts to less than 1 inch (0.6 of an inch, or 1.5 centimeters) of sea level rise contribution from Greenland meltwater since 1900.

So what does a world-renown news organization like the Washington Post do with this contextually-weighted scientific information?   Of course, like most other media organizations in the modern era,  the Post attempts to frighten the public with disturbing trillions of tons of lost ice exclamations without emphasizing the modest and nearly imperceptible sea level impact such “staggering” ice losses produce.

In December, 2015, the Post‘s Chris Mooney summarized “Greenland’s massive, centennial contribution to sea level rise”.


Washington Post  (December, 2015)


It is apparent from reading the article that Mooney is either (a) unaware that less than 1 inch of long-term sea level impact is not “massive”, and therefore using that descriptor in conjunction with  trillions-of-tons of ice loss can be misleading, or (b) he is aware that less than 1 inch of sea level impact in 110 years is not especially alarming, so he buries this inconvenient detail in the body of the article and instead he focuses on employing terms like “staggering” and “massive” and “trillions” and “disturbing” and “alarming” in an effort to conceal.

It would appear that (b) is more likely.

Notice above how Mooney cursorily acknowledges that 1 inch of global-scale sea level rise from 9 trillion tons of melted GIS ice “may not sound like much”.  But then, to recover, he misleadingly pivots to hypothetical scenarios, equating what one inch of sea level rise would do if this water equivalent from across the world ocean was only dumped on the United States’ interstate highway system.  (How does fantasy writing like this make it into a serious science article?)

And then, to pile on another thought experiment, Mooney adds the obligatory “if the entire ice sheet were to melt” conjuring so he can mention that “20 feet of sea level rise” is what’s at stake here.

One inch in 110 years isn’t enough to garner attention, but 98 feet (times 63) of submerged U.S. roads and global coastal areas is quite the scary scenario.

The Washington Post employed this same misleading and diversionary strategy about 8 months later, again relying on the “9 trillion tons of ice” lost study to scare readers.


Washington Post (July, 2016)


If Misleading Readers Wasn’t Allowed, What Would The ‘Honest’ Headlines Look Like?


If news organizations weren’t allowed to mislead readers about climate science, what would the headlines say?

With regard to the long-term (and recent) ice melt records for the Greenland Ice Sheet, a non-deceptive, non-misleading headline might look something like this.

An Iceberg As Big As Delaware–Should We Be Worrying?


An iceberg as big as Delaware!   For those of you that are saying, “what’s a Delaware,?” — it is the second smallest State of the USA’s 50 States.   Even so, an iceberg that big is really impressive.  If it ran into the Titanic, the ship’s orchestra would probably not have had time to play for the people before the ship sank. (That’s from the movie– I am not sure the orchestra really played while the ship sank.)

Around 12 July this year, this huge piece of ice broke off from the Larson C ice shelf in Antarctica. The iceberg, named A68, has an area of 5800 km² (2239 miles²).  The authorities say it is the 5th largest berg in history. Because the continent of Antarctica is so inhospitable, it wasn’t till 1821 when an American seal hunter became the first person to actually put foot on this continent. History, in this instance, is very short.

If you are trying to decide if you should go to Al Gore’s new documentary,  read this first.


Al Gore’s new documentary titled “An Inconvenient Sequel: Truth to Power” opened on July 28 with a limited engagement. Beginning in August, the documentary will be opening in many theaters.  I don’t know how many, as it has not been getting great reviews, but it will be in many more than the initial 4 theaters.

The critics being mostly being quite liberal tend to give this kind of movie a big “thumbs up”. Science has little to do with their ratings of a movie like this, because they are sure if Al Gore produced it, it must all be true. However, the liberal website, VOX said, “Even An Inconvenient Sequel seems a little light on facts at times.” Many of the movie reviewers said it was, in effect, boring.  Maybe that was reflected in the boxofficemojo data published on Sunday, 30 July.  That they said ticket sales for the first day were $61,000, the second day were $43,000 and today (the third day) were $26,000 might reflect the boring viewpoint. 

But Gore did receive the Nobel Peace Prize in 2007 for his first film, didn’t he?  Yes, he did. However, it was the same Nobel Peace Prize Committee that presented the award to the newly elected Barrack Obama before he got into office. They awarded the Peace Prize to Yasser Arafat of the PLO, too.  That Committee has a very transparent political agenda. It has very little to do with peace.

But never fear gentle reader, Al Gore will not let you down.

$535 Trillion To Remove CO2 From The Atmosphere


James Hansen, et al have issued a study titled “Young people’s burden: requirement of negative CO2 emissions.  The authors say that unless CO2 reduction begins right away and aggressively the next generation and the one after that will have to spend a $535 trillion to make Earth habitable.  This $535 trillion is not the $trillions that the warmers want to spend to bring CO2 emissions to a net zero by 2050 or 2100 (depending on which warmer group is talking).  The $535 trillion is for removing atmospheric CO2.

The Hansen et al study says the global temperature will melt glaciers and consequently sea level will rise 6 to 9 meters (approximately 20 to 30 feet). Using models, the study determined a temperature rise due to a rise in atmospheric CO2 and then determined that the glaciers will melt which is the big threat. The authors conclude that the current interglacial period would match the Eemian interglacial period which occurred about 125,000 years ago.   That period is believed to have experienced a 6 to 9-meter sea level rise.  The chart below, from Wikipedia shows the current interglacial period, the Holocene and the Eemian and other interglacial periods. Note that the scale is more or less logarithmic and not linear.

A tangential observation—this chart shows that the Globe’s temperature has been much hotter than at present. Also, the Pleistocene running from about 1 million years ago to about 20 thousand years ago shows glacial and interglacial periods.  The peak temperatures are the time of the interglacial and the rest are the times when some part of Earth was covered by advancing glaciers.  Were there SUVs and fossil fuel powered plants putting out CO2 that caused the glaciers to melt?
