One of the false claims that Global Warming Deniers have
been making in recent years is that “Global Warming Stopped in 1998”.
(Alternately they may pick some other year that “global warming
stopped”.) As per usual, this claim is another deliberate GWD falsehood
that can be easily debunked by looking at the actual observations.

And what do the Global Warming Deniers say about this record warmth?
Temperature records can’t be trusted because:
It’s a conspiracy.

The graph above shows the actual global temperature
anomalies as compiled by NOAA/NCDC (National Oceanic and Atmospheric
Administration / National Climate Data Center - http://www.ncdc.noaa.gov/
) from 1975 to Dec. 2014. Individual months, a 25 month centered moving
average, and a least squares trend line are shown. The graph uses data
that can be found at: https://www.ncdc.noaa.gov/monitoring-references/faq/anomalies.php
The moving average (yellow line) shows that new record
high global temperatures were set through at least Dec. 2014.
Note: NOAA’s National Climatic Data Center (NCDC) maintains the world's largest climate data archive.
One of the features that can be seen is a temperature
spike that showed up in 1998. Late 1997 / 1998 was characterized by an
abnormally strong El Nino event in the equatorial Pacific Ocean. http://en.wikipedia.org/wiki/File:1997_El_Nino_TOPEX.jpg
The equatorial Pacific Ocean covers a lot of geography with the result
that this local event skewed average world temperatures upward for
If you want to use calendar years as your measurement
tool, then the NOAA/NCDC (National Oceanic and Atmospheric
Administration /National Climatic Data Center) data shows that 2005
broke the 1998 average for record warmth. Then 2010 broke the record
again. And 2014 set still another record. (Data available at https://www.ncdc.noaa.gov/monitoring-references/faq/anomalies.php
The NASA / Columbia University temperature database shows a similar pattern. http://data.giss.nasa.gov/gistemp/tabledata_v3/GLB.Ts+dSST.txt
It is interesting to note that by 2014 the major “all-time
record warmth” temperature spike that occurred in 1998 has become just
your normal “everyday” anomaly. As we go into the future, we can expect
a series of additional new all-time record warmth spikes that become
just your normal “everyday” anomalies a decade or two later.
Global Warming Deniers frequently try to misrepresent what
is happening by “Cherry Picking” data such that the time period that
they quote highlights short term random events. The purpose of the
Cherry Picking is to use short term random events to obscure longer
term trends. They selectively pick their “starting point” at a
temperature spike and compare the spike with more recent average
temperatures. They then claim that there hasn’t been any temperature
change from the spike to the current average – thus the claim “Global
Warming has stopped”
Least Squares Trend Lines
When statisticians want to discern a trend from seemingly
random data, they frequently calculate and plot trend lines along with
plotting the original data. The simplest of these is a linear
regression ( http://en.wikipedia.org/wiki/Linear_regression
trend line. There are additional calculations that can be made that
show how well the trend line fits the data and the magnitude of
possible errors, but the simplest analysis simply plots the trend line
along with the original data.
It should be noted that when longer time periods and
larger databases are used, the potential amount of error in the
calculated trend line’s coefficients is reduced. (Potential errors
could be accidental or they could be a deliberate manipulation by
people who want to misrepresent what is actually happening.)
The charts below show that even if you “Cherry Pick” the
time period for your temperature data, least squares regression
analysis is robust enough to still show that world temperatures are
continuing to rise. All the charts use data that is available at: https://www.ncdc.noaa.gov/monitoring-references/faq/anomalies.php
Also please compare each “Cherry Picked” chart with the earlier chart
that shows the temperature record since 1975.
The chart above shows the temperature record and a least squares trend
line with the time period beginning in Jan. 1996. (The 1998 El Nino
event actually started in 1997. Thus 1996 is used for the chart.)
The chart above shows the temperature record and a least squares trend line with the time period beginning in Jan. 1998.
The chart above shows the temperature record and a least squares trend line with the time period beginning in Jan. 1999.
All of the above charts were generated by Microsoft’s
Excel. All of the charts show that the world’s average temperature is
rising. You can alter the slope of the trend line by selectively
picking your starting point, but the directional trend is the same. It
doesn’t make any difference whether you pick a date just before “Global
Warming Stopped in 1998”, right at “Global Warming Stopped in 1998”, or
just after “Global Warming Stopped in 1998”. The actual data shows that
Global Warming Didn’t Stop in 1998.
The 1975 thru 1997 Trend Line had it Right
It is interesting to compare a future forecast that just
uses the 1975 thru 1997 data with what has actually happened since
then. If trend lines have a value, then they should be useful for
predicting the future.
Thus, the NOAA/NCDC data for just Jan. 1975 thru
Dec. 1997 was used for still another analysis. As with the other
charts, the trend line function in Microsoft’s Excel was used to
calculate a trend line. As with the other graphs, only the plotted data
was used for input to Excel’s trend line calculator. The results are
If you use the above trend line to make a temperature
anomaly forecast for the 1998 to 2014 period, what would you expect?
Would you expect temperature anomalies to cluster around the 0.60
level? Now look at the preceding charts. What actually happened?
Please compare the trend line that uses just the Jan. 1975
thru Dec. 1997 data (shown above) with the trend line that uses the
Jan. 1975 thru Dec. 2014 data (first chart). The upward slope of the
two trend lines is almost identical. About the only way that you can
tell that there is a slight difference is to compare the left portion
of the trend lines vs. the yellow 25 month centered moving average.
(For the periods involved, the 25 month centered moving average is
identical for the two graphs.)
The upward trend is the same whether you include the Jan.
1998 to Dec. 2014 data or whether you omit it. If the average
temperature for Jan. 1998 to Dec. 2014 had been something different
than what was forecast by the 1975 thru 1997 data, then the slope
(steepness) of the trend line would have changed. What happened was
that the average increase in temperature for Jan. 1998 thru Dec. 2014
period turned out to be exactly what the trend line forecast.
Global Warming did not stop in 1998.
Land vs. Oceanic Temperatures
It is interesting to compare the temperature record
for land areas vs. the oceans. (Land areas in the northern hemisphere
are used since southern hemisphere land temperatures are more subject
to oceanic modification.)
71 percent of the earth’s surface area is oceanic. Any
forcing that would tend to change the earth’s temperature is slowed by
the oceans since it takes a huge amount of heat input to produce much
temperature change in the massive volume of the oceans.
The chart above shows the Northern Hemisphere “Land
Only” temperature record as measured by NOAA’s National Climate Data
Center. The actual data is available at: https://www.ncdc.noaa.gov/monitoring-references/faq/anomalies.php
The chart above shows oceanic surface temperatures. Again, the actual data is available at: https://www.ncdc.noaa.gov/monitoring-references/faq/anomalies.php
Both charts use the same temperature scale.
If you compare the two charts, there are several
noticeable differences. First, there is a much greater month to month
variation in temperatures for “land only”. This is to be expected since
inland areas such as Chicago are going to have much larger temperature
variations than oceanic areas.
Of greater significance, the rate of temperature rise for
“Land Only” is several times faster than what is seen for ocean
temperatures. The lag effect of the oceans has less influence over land
areas. Thus “land only” temperatures are more “up to date” in showing
what is really happening with global warming. Note that the rate of
temperature rise for land areas as shown by the trend line is 1.4
degrees C in 45 years which is 5.6 degrees F per century.
Greenhouse gases produce thermal forcing which is
equivalent to the heat of just a few mini Christmas tree lights per sq.
meter. It takes decades at this rate to significantly warm an oceanic
column of water that is thousands of feet deep. However this net
forcing is a 24/7 average, and current levels of atmospheric carbon
dioxide have already committed us to hundreds of years of future
The years 2011 – 2013 were characterized by an increase in
mixing between warm surface water and deeper cool water in the earth’s
oceans. (Large storms such as Hurricane Sandy are really good as mixing
agents.) Mixing cools off the surface water - and the air above it.
This mixing caused oceanic surface temperatures to lag further behind
the warming that has been observed in land areas, but once you know
what has held back the “sea” component, it becomes obvious that:
Global Warming did not stop in 1998.
Deep Ocean Heating
As measured by the amount of heat going into the earth’s
oceans, it looks like global warming may have actually accelerated
since the year 2000.
The graph above shows the amount of heat energy that has
been added to the world’s oceans. The original graph can be seen as
Fig. 1 in the published paper “Distinctive climate signals in
reanalysis of global ocean heat content” which can be accessed at http://onlinelibrary.wiley.com/doi/10.1002/grl.50382/full
Note: OHC stands for Ocean Heat Content
To give some idea of the amount of heat that has been added to the oceans, 1023
Joules is enough heat to warm over 67 thousand tons of water from 40
deg. F to 140 deg. F for each of the 7 billion people on planet earth.
(1,000 Joules ~= 0.94845 BTU)
The chart at the right shows the results of other studies that have
measured the increase in oceanic heat content. Thus the results of the
more recent study confirm these earlier studies. The original version
of the graph at the right can be seen at: NOAA’s 2009 “State of the
Climate” report. Downloadable from:
This earlier chart shows the “Heat Content Change” of the
top 700 meters of the world’s oceans as measured by several
researchers. As above, the unit of measure is “Joules” which is the
standard metric measure for energy. (Note: XBT stands for expendable
The vast majority of the heat imbalance due to global
warming actually goes to warming the oceans. The increase in air
temperatures and glacial melting is actually just a small component.
As noted below, the Pacific Decadal Oscillation appears to
determine (or measure) where the heat from thermal forcing ends up. In recent years,
ocean currents (which are subject to the PDO) are continuing to
circulate heat from the ocean’s surface down to deeper levels.
The graph above is from http://www.nodc.noaa.gov/OC5/3M_HEAT_CONTENT/
and updates Ocean Heat Content up through June 2013. The world’s oceans continue to warm at an accelerating pace.
Note: Ocean temperature measurements are made by the Argo buoy system.
It can be easily calculated that the increase in oceanic
heat from 6E22 Joules in 1998 to 19E22 Joules in 2013 is equal to the
accumulated heat content of detonating 4 Hiroshima Atomic Bombs per
second (running 24/7 = 126,000,000+ bombs per year) from 1998 to the
for the 67E12 Joules heat content of one of these bombs.)
The graph above shows the Ocean Heat Content as measured
by the Argo buoy system (red line in the previous graph) up through Dec. 2014. (Data available at http://www.nodc.noaa.gov/OC5/3M_HEAT_CONTENT/basin_data.html
) The slope of the trend line shows us how fast the oceans are warming.
As of Dec. 2014 the warming rate is:
9.5E21 Joules per year
= 4.5 Hiroshima Atomic Bombs per second
= 3.02 trillion 100-watt light bulbs running 24/7.
= 431 100-watt light bulbs for each of the 7,000,000,000 people on planet earth
all running 24/7.
Now calculate your electric bill.
Note: The relatively short time span involved for the above data means
that the calculation for the warming trend will be subject to
variations (possibly +/- 10% in the slope) as new data becomes
available , but the long term warming trend is expected to become even
Conclusion: Global Warming did not stop in 1998.
The PDO and the Rate of Atmospheric Temperature Rise
The rate that atmospheric temperatures rise is a complex
function that includes all possible components. One of these components
is the Pacific Decadal Oscillation. A detailed description of the
PDO can be seen here. http://jisao.washington.edu/pdo/
Ocean currents in the Pacific Ocean are known to undergo small changes
depending on the positive or negative state of the PDO.
The chart above shows the PDO Index starting with 1975. Data for the chart can be seen at: http://jisao.washington.edu/pdo/PDO.latest
Note that the PDO was mostly negative for the 30-year period before 1975.
The PDO appears to be a way of measuring the mixing rate
between surface water and deep water in the Pacific Ocean. When the PDO
Index is predominately positive, there appears to be less mixing of
surface and deep water in the Pacific Ocean. This allows rapid surface
warming. (Including the air in contact with it.)
When the PDO is positive, atmospheric temperatures rise rapidly in response to carbon dioxide forcing.
When the PDO is predominately negative, it means that the
mixing rate between surface and deep water in the Pacific Ocean is
greater. An increased amount of warm surface water sinks deeper into
the ocean and an increased amount of colder deep water rises to replace
it. (This frequently shows up as a La Nina episode.) This colder water
cools the air that is in contact with it. When the PDO is negative, global
warming as measured by atmospheric temperatures proceeds at a slower
rate because more of the carbon dioxide forced heating goes into the
deep ocean instead of the atmosphere.
Global warming is going to continue no matter what state
the PDO is in. The PDO just controls where the heat is going.
The Satellite Temperature Record
Satellites can measure “brightness” microwave radiation
which can be translated into temperatures. What the satellites lack in
surface detail is offset by their ability to quickly observe the whole
The University of Alabama – Huntsville uses NASA’s
satellites to monitor global temperatures. The graph below shows what
has been observed up through Jan. 2015.
The data source for the above graph is the “Globe” column at:
It would be of interest as to just how Global Warming Deniers define their claim that “Global Warming Stopped in 1998”.
The reason that global warming is occurring is that
human activities have modified the earth’s ability to radiate heat back
out into space. The requirement for the earth’s temperature to remain
constant is that incoming solar energy (“solar irradiance”) must be
balanced by a combination of reflection of this incoming solar
radiation and outgoing long wave heat radiation. If incoming solar
radiation is relatively constant (and it is), but outgoing heat
radiation is reduced, then the earth will warm until rising
temperatures (which increase outgoing radiation) can establish a new
Human activities have changed the earth’s ability to
radiate heat. Since the beginning of the industrial revolution,
combustion of fossil fuels (natural gas, oil, and coal) have increased
the atmospheric content of carbon dioxide by over 40%. Carbon dioxide
slows the earth’s ability to radiate heat into space. Carbon dioxide
and multiple other human generated components have altered the heat
balance that existed before the industrial revolution.
This imbalance caused by human activities is called
“Radiative Forcing”. That chart below illustrates the various
components of climate forcing, and shows the changes in the net
magnitude of this forcing since 1750.
The chart above is part of the “Summary for Policymakers”
section of the IPCC’s AR5 report. The top portion shows the various
components and the magnitude of their forcing. The bottom portion shows
the increasing amount of forcing for various years as measured against
what existed in the year 1750.
The “Solar” component is of interest. Global Warming
Deniers try to sidestep the issue by blaming the sun for global
warming. The change in irradiance from the sun is negligibly small
compared to 1750 values, and has actually decreased since the
mid-1980s. Thus Global Warming Deniers are wrong again when they claim
the sun is responsible.
As a technical note, notice that all the molecules listed
under “Resulting Atmospheric Drivers” have 3 or more atoms in each
molecular compound. Molecules that have 3 or more atoms are capable of
absorbing (and reradiating) long-wavelength heat radiation while
ordinary atmospheric oxygen (O2
) and nitrogen (N2
) form molecules with
only 2 atoms each. Molecules that only have 2 atoms do not absorb
long-wavelength radiation (the radiation at ordinary temperatures).
Thus ordinary oxygen and nitrogen which compose most of the content of
the atmosphere are not directly involved in the earth’s heat budget.
Overall, forcing is increasing and, most likely, will
continue to increase for many decades into the future. Other feedback
factors such as increased water vapor in the atmosphere are only
beginning to kick in, and will become much stronger in the future. The
continuing increase in forcing supports the observation from oceanic
heating (shown earlier) that total global warming is accelerating.
Planet earth will be a much different place by the time temperatures
warm enough to reestablish thermal equilibrium.
Other Confirming Observations that Global Warming is Continuing
The chart above (compiled by the World Glacier Monitoring Service) shows what is happening to the world’s
glaciers. They are melting! Not only are the world’s
glaciers shrinking, the shrinkage rate has accelerated in recent years.
For an updated version of the graph, please see the mass balance
studies at http://www.geo.uzh.ch/microsite/wgms/
As for the false claims by the Deniers that glaciers
in the Himalayas are advancing, a detailed study that analyzed 7,090
glaciers in central Asia (including the Himalayas and Karakoram) and
that was published in 2012 ( http://www.nature.com/nclimate/journal/v2/n9/full/nclimate1580.html
) found that:

“We reveal that the glaciers have been significantly losing mass since
at least 1970, despite thick debris cover. The specific mass loss for
1970–2007 is 0.32±0.08mw.e. a−1”
(mw.e. a-1 = meters of water equivalent per annum(year))
The world’s glaciers did not stop melting after 1998.
NASA has independently measured that the world’s glaciers
are melting. How about 4.3 trillion tons of melting from 2003 to 2010?
If global warming stopped in 1998, what melted 4.3 trillion tons of ice?
Argentina’s Upsala Glacier 2003 to 2011
The Upsala Glacier is one of the larger outflow glaciers
from the Southern Patagonia Icefield. The two pictures below were
generated by Google Earth. The yellow line was generated by Google
Earth’s distance measuring tool, and is over two miles long. The small
blue squares show where people have taken photographs.
The picture above shows the Upsala Glacier as of May 11, 2003.
The picture above shows the Upsala Glacier as of Dec. 28,
2011. Icebergs and many smaller ice fragments are floating on a lake
which now occupies the former location of the glacier.
If Global Warming stopped in 1998, what caused the Upsala Glacier to melt back over 2 miles from 2003 to 2011?
Alaska’s Columbia Glacier
The first two pictures below are from Time/NASA’s time lapse video.
The first picture shows Alaska’s Columbia Glacier as of
1998. (The glacier is just to the left of the center of the picture.) Open water is
dark blue. Snow and ice are white.
This next picture shows the Columbia Glacier as of 2012.
Note how the former white area of the glacier has been replaced by dark
blue ocean water.
Finally, this third picture shows a Google Earth view of
the same area. Google Earth’s distance measuring tool has been used to
show that the glacier has melted back 11 miles. (Yellow line.)
If Global Warming stopped in 1998, what melted 11 miles of the Columbia Glacier after 1998?
Polar Sea Ice Extent
Another “claim” by Global Warming Deniers is that Polar Sea Ice Extent is expanding. Again, this is another Lie.
The above chart is from NASA’s Earth Observatory.
(As published by the American Meteorological Society http://journals.ametsoc.org/doi/abs/10.1175/JCLI-D-14-00605.1
The chart shows Polar Sea Ice Extent as observed by
satellites from 1979 thru 2013. There has been a slight increase in
Antarctic Sea Ice Extent but this has been more than offset by larger
declines in Arctic Sea Ice Extent. The combined sea ice extent is in a
(From the NASA link)
“Furthermore, the global sea ice loss
has accelerated. From 1979 to 1996, the ice loss was 21,500 square
kilometers (8,300 square miles) per year. This rate from 1996 to 2013
was 50,000 square kilometers (19,500 square miles) lost per year.”
Note: The increase in sea ice around Antarctica was forecast 13 years ago.
[Antarctic sea ice cover] is also qualitatively consistent with the
counterintuitive prediction of a global atmospheric-ocean model of
increasing sea ice around Antarctica with climate warming due to the
stabilizing effects of increased snowfall on the Southern Ocean.”http://onlinelibrary.wiley.com/doi/10.1029/2000JC000733/full
If Global Warming stopped in 1998, why has sea ice extent accelerated its downtrend – including a new record low in 2012?
Sea Level is Rising
The chart above shows what is happening to sea level. As
the world warms, sea level rises due to thermal expansion plus water
from melted glacial ice. The most recent data at
indicates this rate of sea level rise is continuing to accelerate
beyond what was observed up through 2011.
The chart above is a copy of what can been seen at Columbia University’s web page at http://www.columbia.edu/~mhs119/SeaLevel/
. The rate of sea level rise has quadrupled since the 1870 to 1924 period.
“So-called "nuisance flooding" -- which causes public inconveniences
such as frequent road closures, overwhelmed storm drains, and
compromised infrastructure -- has increased on all three U.S. coasts,
between 300 and 925 percent since the 1960s”
If global warming stopped in 1998, what is causing sea level to rise?
Holland Island and Sea Level
Holland Island is one of the famous (and a bit sad) stories of sea level rise.
In 1900 Holland Island had a population of 253. Today, due
to sea level rise and subsidence, there is nothing left standing.
(Click on image for a large version)
A 2013 Google Earth view of the Holland Island area is
shown on the left along with an 1898 map on the right. Since 1898, Long
Island and the unnamed islet north of it are gone. The north end of
Adam Island has been submerged to where only a few sand bars are left.
The north to south peninsula that used to exist on the
southwest side of Holland Island no longer exists. The marshy peninsula
on the southeast side of Holland Island is also gone. The northern
peninsula that extended nearly to Adam Island has been reduced to a few
sand bars. This is where the “Last House on Holland Island” stood until
2010. It is now gone.
Sea level is expected to rise 20 feet over the next 1,000
years. (See “Eemian interglacial” in the next section (below))
This is enough to submerge major coastal cities including Miami and New
Orleans. Over the next 1,000 years these and other cities will
gradually be abandoned just as Holland Island has been abandoned.
Sometime between now and 1,000 years from now, there will be a “Last
Building in Miami”. 1,000 years from now, it too will be gone.
The process of abandonment will be gradual salt water
intrusion which will rot building foundations and destroy fresh water
supplies. (Throw in a hurricane or two for good measure.) Taxes will
gradually/relentlessly be increased for public works programs to try to
protect what is left. The current population will try to hold out, but
future generations will understand what is happening. They will decide
to live somewhere else.
Ditto for New Orleans.
The 800,000 Year Historical Carbon Dioxide Record
NOAA’s Earth System Research Laboratory has an animation video at http://www.esrl.noaa.gov/gmd/ccgg/trends/history.html
that shows the historical record of what humans are doing vs. what
“Nature” does. The chart below is a print screen image from this video.
The near vertical line at the right end of the graph shows
what human activities have done in the last few decades. The
atmospheric concentration of carbon dioxide due to human activities
continues to accelerate upwards.
In the Eemian interglacial that peaked about 125,000 years
ago, sea level rose so that the nearest land to what is now Miami, FL
was some 35 to 40 miles away. What do you suppose will happen when
glacial melting and thermal expansion of the oceans catches up to what
we have already done?
A Typical Example of a GWD “Source” for the “Stopped” Lie
On Oct. 13, 2012 a British Global Warming Denier tabloid
(the “Mail Online”) ran a story with the following headline:
“Global warming stopped 16 years ago,
reveals Met Office report quietly released...
and here is the chart to prove it”
The author of the article (David Rose) has a history
of willful misrepresentations of reality. But then again, neither David
Rose nor his tabloid audience are interested in factual evidence.
The story included the following chart:
“Firstly, the Met Office has not issued a report on this issue.”
Thus when the headline states that there was a report, it is just another Global Warming Denier lie.
The above graph (which has a “Ben Weller”
label as a source) has been widely circulated in Global Warming Denier
blogs on the Internet. The article contains no source reference for the
“temperature data” in the graph. The origin and credibility for the
chart data is unknown, and the only information we have is that the
chart was authored by “Ben Weller”.
It’s instructive to compare the graph that was
published in the Daily Mail’s “Mail Online” with the actual temperature
record as compiled by the UK’s Climate Research Unit.
The graph above shows the Hadley Climate Research Unit’s
monthly temperature anomalies from 1975 to Jan. 2015. The data can be accessed and checked for accuracy at
(Note: Old versions of the table are subject to minor changes as corrections and late data become available.)
The 35 month centered moving average (yellow line) is
of interest. It shows that average temperatures beginning in Dec.
2001 have been consistently warmer than the warmest 35 month average
that was seen in 1998. If global warming stopped in 1998, why have
temperatures for the last 12 years averaged warmer than what was observed
In spite of what the Mail Online article claims, it is obvious that Global Warming didn’t stop in 1998.
The HadCRUTEM4 data can be easily traced to
an actual temperature database. The Daily Mail “Mail Online” graph is
attributed to “Ben Weller”.
Who or what is Ben Weller?
Google searches using
“Ben Weller” climate
“Ben Weller” meteorology
“Ben Weller” temperature
return links to various blogs/forums/websites that discuss the article,
but not to any source that would indicate that “Ben Weller” works for
any scientific organization. Conclusion: The “Ben Weller” name on the
chart does not refer to a scientific organization.
There is a Ben Weller freelance photographer who has
contributed work to the Daily Mail/Mail Online. The suspicion arises
that Ben Weller has widened his repertoire to include fabricating
As for the Daily Mail’s/Mail Online’s “journalistic
credibility”, you should realize that they devote a lot of attention to
“features” such as:
Over 19,000 hits at the DailyMail website.
Over 180,000 hits at the DailyMail website.
Readers should understand that the Daily Mail/Mail Online
(and most other publishers) will publish articles that are targeted
toward a specific audience - including the audience’s (willfully
ignorant) “intelligence” level.
The source data for the “Global Warming Stopped” headline
is unknown. However, Global Warming Deniers are gullible,
scientifically ignorant fools who will believe any LIE as long as it
supports what they want to believe. Thus they fabricate a mysterious
temperature record and then point to this fabricated temperature record
as if it were true.
“Red Handed” Evidence that Global Warming Deniers are Liars
The Mail Online/Daily Mail generously provides evidence that they print
lies. Here is a Print Screen copy from the Mail Online’s web page on
Sept. 19, 2013.
The Mail Online asserts “the fact that 1998 was the hottest year on record and world temperatures have not yet exceeded it”.
If we check the world’s temperature databases we find that:
1) GISS/NASA shows that 2005, 2007, and 2010 were all warmer than 1998.
2) NOAA/NCDC shows that 2005 and 2010 were warmer than 1998.
3) HadCRUT4 shows that 2005 and 2010 were warmer than 1998.
4) And the UAH satellite temperature graph (above) shows that global
temperatures have been consistently above the 1998 moving average for the
last 14 years.
The Mail Online is lying again when it states that 1998
was the warmest year on record. Then they fabricated a claim that there
is a cover-up.
The top of this web page states that Global Warming
Deniers “lie, they are willfully ignorant, and they are wrong.” The
Mail Online is a perfect example demonstrating that Global Warming
Deniers are liars.
Still Another Willful Lie by David Rose & The Daily Mail/Mail Online
On March 16, 2013 The Daily Mail/Mail Online ran the above chart.
David Rose and The Daily Mail/Mail Online claim that
temperatures are not following the predictions made by the IPCC. The
graph has been widely circulated in the Global Warming Denier
Does the Daily Mail/Mail Online chart show what the IPCC
actually said, or is the Daily Mail/Mail Online chart a fabrication of
what the IPCC really said?
The chart above shows what the IPCC really printed in their 2007 report. http://www.ipcc.ch/pdf/assessment-report/ar4/wg1/ar4-wg1-chapter1.pdf
The Daily Mail/Mail Online and David Rose willfully fabricated still another lie.
Another Global Warming Denier Lie
As documented above, Global Warming Deniers are not above fabricating false “reports”. Here’s the headline of another example:
“UN Hiding Reports About Inaccurate Global Warming Numbers”
This of course is not true, but the assertion needs to be debunked.
The “title” of the actual “report” is:
HOW THE IPCC HID THE GOOD NEWS ON
The content of the “Report” is actually Global Warming
Denier propaganda put out by “The Global Warming Policy Foundation”.
In turn the GWPF is a “Think Tank” headed by British
Politician Lord Lawson – who by an “amazing coincidence” is the same
Lord Nigel Lawson who was one of the people featured in Martin Durkin’s
pseudo-documentary “The Great Global Warming Swindle”.
Martin Durkin: “Legitimate scientists - people with qualifications - are the bad guys”
The scientific validity of the “report” is zero.
An Individual Global Warming Denier
Liar and/or Willful Ignoramus
“Wing Nut” media often promote “name” people to promote
Global Warming Denier ideology – mostly because the GWDs don’t have any
evidence - leaving “noise making” as their denial weapon of choice. One
of these people is the 80-year old John Coleman.
Original source of the picture above was: “Prominent dingbat wants to sue Al Gore for fraud” http://scholarsandrogues.com/2008/03/14/prominent-dingbat-wants-to-sue-al-gore-for-fraud/
John Coleman has minimal qualifications and no evidence to
back up his mistaken opinions. He has no educational background in
either meteorology or climatology. His degree is in Journalism. http://en.wikipedia.org/wiki/John_Coleman_(news_weathercaster)
Just like P. T. Barnam (“I am a showman by profession...and all the gilding shall make nothing else of me” http://en.wikipedia.org/wiki/P._T._Barnum
), Coleman’s “expertise” consists of entertaining the masses – not educating them.
His contribution as cofounder of the Weather Channel
lasted one year before he was forced out (more than 30 years ago) by
the other cofounder. (Due to major operating losses – Coleman was CEO
and president.) “Eventually, Landmark forced Coleman out of TWC.” The
falling out included a lawsuit which Coleman apparently lost.
(It appears that KUSI is trying to “vanish” this web page. If anyone
would like Print-Screen copies of what it used to look like, please
send me an email and I’ll attach the images to my reply.)
In regard to Coleman’s quote
“There is no significant man-made global warming at this time, there has been none in the past”
perhaps John Coleman should take a vacation trip to visit the (former) glaciers on the Matterhorn.
As for the Weather Channel itself:
“Accuweather” has the same conclusion.
“Global Warming has Not Stopped”
For more information on John Coleman, please see the Guardian article:
“Weather Channel co-founder John Coleman prefers conspiracies to climate science”
Our Lying Political Leaders
Lying isn’t limited to just television, newspaper, and
media. It also takes place in the U. S. Senate. The picture below is an
excerpt from the Congressional Record.
(Click on picture for a large image.)
The picture above shows Oklahoma’s Senator Jim Inhofe lying, as documented in the Congressional Record. https://www.congress.gov/crec/2014/07/28/CREC-2014-07-28-pt1-PgS4988-2.pdf
Senator Jim Inhofe said:
“In fact, for the past 15 years
temperatures across the globe have not increased. Let’s think about
that. Is anyone listening here? Temperatures have not increased over
the last 15 years.”
(If you follow the link, scroll down one page to get to page S4989.)
Please check the NOAA/NCDC “1998 to Present” and “1999 to Present”
charts (shown earlier) to see what “the scientific record” recorded for
this time period.
Also, please see another example of a Global Warming Denier’s assertion that Global Warming has stopped.
The Fabius Maximus Website is an example of a Global Warming Denier
website. A look at the evidence that GWDs lie, they are willfully
ignorant, and they are wrong.
Global Warming Models
How accurate are the computer models that are used to
forecast global warming? The chart below is from an in depth essay on
global warming at the American Institute for Physics. http://www.aip.org/history/climate/summary.htm
The top part of the chart shows actual observed
temperature anomalies vs. what the computer models produce. The bottom
part of the chart shows 4 primary components that are used for the
computer models. Volcanic eruptions and El Nino are basically random
events, and thus their short term fluctuations cannot be predicted in
advance. A good reference for tracking current El Nino status is the
Earth System Research Laboratory’s web page at:
Solar irradiance varies slightly with the 11year sunspot
cycle. There is some variability in the length of the cycle and its
magnitude, but overall it has just a small influence and irradiance has
actually been negative in recent decades.
The largest influence is “Anthropogenic Effects” with
human generated carbon dioxide outweighing all other components. With
atmospheric carbon dioxide on a relentless climb, guess what is going
to happen to the earth’s temperature in the future?
“Computer Climate Models Are Not Fundamentally Flawed”
As reported at:
“Fifteen-year temperature trends. The solid black line is the time
series of the global mean surface temperature, plotted as a departure
(anomaly) from a baseline period 1961–90. The dashed black line is a
smooth fit to this series, representing the long-term warming rate. The
blue and red lines are linear trends for each 15-year segment running
over 1850–64, 1851–65, …, 1999–2013. Each 15-year segment is shown in
red if the trend rises faster than the long-term warming rate in the
same 15-year period and blue if it rises more slowly. Marotzke and
Forster show that these 15-year trends are dominated by natural (free)
variations. The free variations drive the 15-year trends above and
below the long-term warming rate as they ride along with it. Courtesy:

Our Best Knowledge
The best information about changes in the world’s climate can be found in our best educational institutions.
The following organizations provide evidence that:
1) Global Warming / Climate Change is real.
2) Human activities are by far the largest causative agent.
3) Global Warming / Climate Change is a continuing, ongoing phenomenon.
Massachusetts Institute of Technology
“Report: Human activity fuels global warming”
California Institute of Technology
“How We Know Global Warming is Real”
“The science behind human-induced climate change”
(If link is broken use:http://web.archive.org/web/20131228065558/http://www.gps.caltech.edu/~tapio/papers/skeptic_2008.pdf
“A large body of scientific information indicates that global climate
change is unequivocal, almost certainly is caused mostly by human
activities, is already causing significant harm, and as it continues,
holds great risks for our future.”
“The Greenhouse Effect and Global Warming”
“With higher CO2 concentrations come expectations of a stronger greenhouse effect and therefore warmer global temperatures.”
Atmospheric Sciences - University of Illinois - Champaign
“Evidence continues to mount that human activities are altering the Earth’s climate on a global scale.”
Woods Hole Oceanographic Institution
Scripps Institution of Oceanography (University of California - San Diego)
If global warming stopped in 1998, please provide an explanation
as to why our best schools and universities are providing evidence that
global warming is continuing.
The actual observations show that global warming didn’t
stop in 1998. What is happening is that a few Global Warming Deniers
fabricated a story, and the other members of the Global Warming Denier
cult continue to demonstrate their willful ignorance by repeating the
same false story.
