5000 Years Of Climate Change From Greenland Ice Cores

Basic Mistakes of Catastrophic Global Warming Believers

Errors of Logic:

Unusual weather occurrences are not evidence of its cause

Correlation is not causation

An expert’s assertion is not evidence.

Government assertions are not evidence.

Consensus is not evidence

“What else could it be” is not evidence

Ignoring Basic facts:

Man emits 4% of annual CO2 emissions, nature 96%

CO2 causes only  9-26% of the warming. Water vapor with clouds 66% to 85%   

Ice core data show CO2 follows temperature - a cause must happen BEFORE the effect

Climate is cyclical including short term, 1000 year and longer cycles

Its been warmer in the past (and cooler too.)

There have been more (and less) storms in the past.

There have been more (and less) floods/droughts in the past.

Trillions of dollars are being made from the climate scare.

Errors  Interpreting Weather :

Most unprecedented weather is actually not. (weather records go back 100-150 years, current inter-glacial goes back 10,000 years, climate goes back BILLIONS of years)

First time in 100 years means it is a repeat of 100 years ago.

Climate is extremely variable - Minoan,  Roman, & Medieval warm Periods separated by periods of cold. (Cold in CharlesDickens’s little ice age period novels, Hannibal crossing the Alps with elephants during Roman warm period.)


Errors of Logic

Unusual weather occurrences are not evidence of its cause - We DO NOT have any real data on how variable the climate can be since we only have records of the last  360 years out of  4 Billion years of Earth’s existence. That is  0.00001% of the climate.

Correlation is NOT causation.

Here are some false correlations that prove correlation is NOT causation: http://www.tylervigen.com/spurious-correlations

If there is causation, there is correlation. If there is no causation, there might be aberrant correlation. If there is correlation, there might be causation. If there is no correlation, there is no causation.---http://wmbriggs.com/post/6319/
What That Spurious Correlation Website Tells Us About Statistics --
Causation And Correlation ---http://wmbriggs.com/post/10601/
Correlation does not imply causation  --

An expert’s assertion is not evidence.  The expert might be wrong, why not look at his evidence?

Government assertions are not evidence. Governments at all levels are famous for lying.

Consensus is not evidence. This is the same as the two above items.  “Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. “   Michael Crichton.

“What else could it be” is not evidence.  This assumes that we know ALL possible cause - we do not.

Ignoring Basic facts:

Man emits 4% of annual CO2 emissions, nature 96%

Various sources show different numbers, but here is the NASA version - add up the CO2 on this NASA carbon cycle chart:


They show man emits 4.3% of the annual emissions (man: 9; nature: 210)

The sums are done here: http://www.debunkingclimate.com/co2_sources-2.html

This is by one of the scientists who run the satellite climate data at UAH:
Increasing Atmospheric CO2: Manmade…or Natural?

CO2 causes only 9-26% of the warming. Water vapor with clouds 66% to 85%

“CO2 alone makes up between 9 and 26%” realclimate.org/index.php?p=142 (this is a site run by NOAA/NASA scientists set up to defend the climate alarm viewpoint

Ice core data show CO2 follows temperature - a cause must happen BEFORE the effect

realclimate.org/index.php?p=13 (ignore their speculation that further warming “could in fact have been caused by CO2” - it is mere speculation as evidenced by their use of the term “could in fact”.)

Climate is cyclical including short term, 1000 year and longer cycles

MAGNITUDE AND RATE OF CLIMATE CHANGES https://wattsupwiththat.com/2011/01/24/easterbrook-on-the-magnitude-of-greenland-gisp2-ice-core-data/

The interactive graph, Greenland Ice Core Temperature Anomaly Data (GISP2), at http://www.ces.fau.edu/nasa/module-3/temperature-changes/exploration-2.php shows recent temperatures at the far right(10,000-0 years ago) are around -.36 degree which is considerably below earlier peaks of 3.02, 2.73, 2.92, 1.85, 0.98 degrees.
You can see several swings of 2+ degrees over that period. Since recent temperatures are negative, we are clearly cooler than those +2.7 & +3 degree times, even if we have warmed a bit since the end of the data shown.

See more data at:

For our best ground based data, see the US Climate Reference Network at http://www.ncdc.noaa.gov/temp-and-precip/national-temperature-index/time-series? Note that this DOES NOT support claims of the last couple years being the warmest ever - 2012 was in this short series.

Radiosonde (weather balloon) data shows no warming since 1958 and its accuracy is substantiated by its matching satellite records over the shorter satellite record.) see: Fig 9 of
Also this secondary source:

Here is the oldest continuous temperature record that we have (kept by the British Met office):
Note that the 2017 temperature is less than one degree above hundreds of years ago peak years of 1666, 1686, 1736, 1779, 1834, 1868 and less than 1/2 degree above many of them. That's not much warming, and too old to be due to man's Co2 emissions! (The usual method of averaging temperatures hides these peaks and emphasizes later years because the peaks are closer together in the later years.)

Its been warmer in the past (and cooler too.)

See above section plus this:

Minoan, Egyptian, Roman and Medieval times were probably warmer than recently.

There have been more (and less) storms in the past.

"With increased National Doppler radar coverage, increasing population, and greater attention to tornado reporting, there has been an increase in the number of tornado reports over the past several decades. This can create a misleading appearance of an increasing trend in tornado frequency. To better understand the variability and trend in tornado frequency in the United States, the total number of EF-1 and stronger, as well as strong to violent tornadoes (EF-3 to EF-5 category on the Enhanced Fujita scale) can be analyzed. These tornadoes would have likely been reported even during the decades before Doppler radar use became widespread and practices resulted in increasing tornado reports. The bar charts below indicate there has been little trend in the frequency of the stronger tornadoes over the past 55 years." https://www.ncdc.noaa.gov/climate-information/extreme-events/us-tornado-climatology/trends (see chart on that page)

This summary page has charts that shows:
No trend in Global Tropical Cyclone Accumulated Cyclone Energy (ACE) – 1971 to Present
Slight decrease in Global Tropical Cyclone Frequency- 1971 to Present
No trend Global Hurricane Frequency – 1978 to Present
Decrease in US Hurricanes 1851 – 2010
Little trend in Australian Region Tropical Cyclones 1970–2011
Decrease in US Strong to Violent Tornadoes (EF3-EF5*) – 1950 to Present
no trend in U.S. Tornadoes (EF1-EF5) – Annual Count 1954 – 2012
Decrease in Global Palmer Drought Severity Index (PDSI) – 1950 – 2010 (area chart shows increase)
No trend in US and North American Drought Comparison (dates on graph are 1900 to present)

"In Historic Storms of the North Sea, British Isles and Northwest Europe (henceforth ‘Historic Storms’), Lamb and Frydendahl (1991) provide synoptic reconstructions alongside detailed descriptions of the major storms crossing the region since the year 1509. Storm events were selected for inclusion based on either the severity of the wind damage or historical significance, and were reconstructed by collating a variety of information." https://wattsupwiththat.com/2015/08/19/how-does-the-ipcc-explain-the-severe-storms-of-history/

Six charts of storm time series from IPPCC show no clear increase:

There have been more (and less) floods/droughts in the past.

Decrease in Global Palmer Drought Severity Index (PDSI) – 1950 – 2010 (area chart shows increase)
No trend in US and North American Drought Comparison (dates on graph are 1900 to present)

Isotope rations DO NOT PROVE atmospheric CO2 increase is due to man’s CO2 (Suess Effect)

Examples of similar 13c from before man burned fossil fuels shows this is NOT evidence of man’s origion:

Fig 2) 13C depletion during Holocene Climatic Optimum in the Thar Desert of Northwest India (Enzel et al., 1999).

Fig 3) 13C depletion during Preboreal to Boreal in western Poland (Apolinarska, 2009).

Fig 4) 13C depletion during last interglacial in the Indian Ocean (Banakar, 2005).

Fig 5) 13C rise and depletion across the Little Ice Age in the Yucatan compared to recent 13C depletion in the Coral Sea.
