MJ, what you are doing is akin to showing the group your latest stool sample.  
It may be something that you find fascinating but nobody else wants to hear 
your shit.

CLIMATE CHANGEMYTHS / FACTS

COMMON MISCONCEPTIONS ABOUT GLOBAL WARMING

MYTH 1: Global temperatures are rising at a rapid, unprecedented rate.

FACT: The HadCRUT4 surface temperature index, produced by the Hadley Centre of
the UK Met Office and the Climate Research Unit of the University of East
Anglia, shows warming to 1878, cooling to 1911, warming to 1941, cooling to
1964, warming to 1998 and cooling through 2011. The warming rate from 1964 to
1998 was the same as the previous warming from 1911 to 1941. Satellites,
weather balloons and ground stations all show cooling from 2002 through mid
2015, then this warming pause ended with a large El Nino event starting late
2015. The average of two analysis of satellite data gives a trend from 1979 to
Nov. 2017 of 0.13 ºC/decade, which is less than half of the corresponding trend
of 0.27 ºC/decade of the climate models. The mild warming of about 0.7 ºC over
the 20th century is well within the natural variations recorded in the last
millennium. The ground station network suffers from an uneven distribution
across the globe; the stations are preferentially located in growing urban and
industrial areas ("heat islands"), which show substantially higher readings
than adjacent rural areas ("land use effects"). Two science teams have shown
that correcting the surface temperature record for the effects of urban
development would reduce the reported warming trend over land from 1980 by
half. See here.

There has been no catastrophic warming recorded.

MYTH 2: The "hockey stick" graph proves that the earth has experienced a
steady, very gradual temperature decrease for 1000 years, then recently began a
sudden increase.

FACT: Significant changes in climate have continually occurred throughout
geologic time. For instance, the Medieval Warm Period, from around 1000 to1200
AD (when the Vikings farmed on Greenland) was followed by a period known as the
Little Ice Age. Since the end of the 17th Century the "average global
temperature" has been rising at the low steady rate mentioned above; although
from 1940 – 1970 temperatures actually dropped, leading to a Global Cooling
scare.

The "hockey stick", a poster boy of both the UN's IPCC and Canada's Environment
Department, ignores historical recorded climatic swings, and has now also been
proven to be flawed and statistically unreliable as well. It is a computer
construct and a faulty one at that. See here for more information.

MYTH 3: Human produced carbon dioxide has increased over the last 100 years,
adding to the Greenhouse effect, thus causing most of the earth's warming of
the last 100 years.

FACT: Carbon dioxide levels have indeed changed for various reasons, human and
otherwise, just as they have throughout geologic time. Since the beginning of
the industrial revolution, the CO2 content of the atmosphere has increased by
about 120 part per million (ppm), most of which is likely due to human-caused
CO2 emissions. The RATE of growth during this century has been about
0.55%/year. However, there is no proof that CO2 is the main driver of global
warming. As measured in ice cores dated over many thousands of years, CO2levels
move up and down AFTER the temperature has done so, and thus are the RESULT OF,
NOT THE CAUSE of warming. Geological field work in recent sediments confirms
this causal relationship. There is solid evidence that, as temperatures move up
and down naturally and cyclically through solar radiation, orbital and galactic
influences, the warming surface layers of the earth's oceans expel more CO2 as
a result.

MYTH 4: CO2 is the most common greenhouse gas.

FACT: Greenhouse gases form about 3% of the atmosphere by volume. They consist
of varying amounts, (about 97%) of water vapour and clouds, with the remainder
being gases like CO2, CH4, Ozone and N2O, of which carbon dioxide is the
largest amount. Hence, CO2 constitutes about 0.04% of the atmosphere. While the
minor gases are more effective as "greenhouse agents" than water vapour and
clouds, the latter are overwhelming the effect by their sheer volume and – in
the end – are thought to be responsible for 75% of the "Greenhouse effect".
(See here) At current concentrations, a 3% change of water vapour in the
atmosphere would have the same effect as a 100% change in CO2.

Those attributing climate change to CO2 rarely mention these important facts.

MYTH 5: Computer models verify that CO2 increases will cause significant
global warming.

FACT: The computer models assume that CO2 is the primary climate driver, and
that the Sun has an insignificant effect on climate. Using the output of a
model to verify its initial assumption is committing the logical fallacy of
circular reasoning. Computer models can be made to roughly match the 20th
century temperature rise by adjusting many input parameters and using strong
positive feedbacks. They do not "prove" anything. Also, computer models
predicting global warming are incapable of properly including the effects of
the sun, cosmic rays and the clouds. The sun is a major cause of temperature
variation on the earth surface as its received radiation changes all the time,
This happens largely in cyclical fashion. The number and the lengths in time of
sunspots can be correlated very closely with average temperatures on earth,
e.g. the Little Ice Age and the Medieval Warm Period. Varying intensity of
solar heat radiation affects the surface temperature of the oceans and the
currents. Warmer ocean water expels gases, some of which are CO2. Solar
radiation interferes with the cosmic ray flux, thus influencing the amount
ionized nuclei which control cloud cover.

MYTH 6: The United Nations' Intergovernmental Panel on Climate Change (IPCC)
has proven that man–made CO2 causes global warming.

FACT: In a 1996 report by the UN on global warming, two statements were
deleted from the final draft approved and accepted by a panel of scientists.
Here they are:
1) “None of the studies cited above has shown clear evidence that we can
attribute the observed climate changes to increases in greenhouse gases.”
2) “No study to date has positively attributed all or part of the climate
change to man–made causes”

To the present day there is still no scientific proof that man-made CO2 causes
significant global warming.

See a Wall Street Journal article here.

MYTH 7: CO2 is a pollutant.

FACT: This is absolutely not true. Nitrogen forms 80% of our atmosphere. We
could not live in 100% nitrogen either. Carbon dioxide is no more a pollutant
than nitrogen is. CO2 is essential to life on earth. It is necessary for plant
growth since increased CO2 intake as a result of increased atmospheric
concentration causes many trees and other plants to grow more vigorously.
Unfortunately, the Canadian Government has included CO2 with a number of truly
toxic and noxious substances listed by the Environmental Protection Act, only
as their means to politically control it. The graph here shows changes in
vegetative cover due to CO2 fertilization between 1982 and 2010 (Donohue et
al., 2013 GRL). A major study here shows that CO2 fertilization will likely
increase the value of crop production between now and 2050 by an additional
$11.7 trillion ($US 2014). See here for more discussion.

MYTH 8: Global warming will cause more storms and other weather extremes.

FACT: There is no scientific or statistical evidence whatsoever that supports
such claims on a global scale. Regional variations may occur. Growing
insurance and infrastructure repair costs, particularly in coastal areas, are
sometimes claimed to be the result of increasing frequency and severity of
storms, whereas in reality they are a function of increasing population
density, escalating development value, and ever more media reporting. See here
for graphs and discussion of extreme weather.

MYTH 9: Receding glaciers and the calving of ice shelves are proof of man-made
global warming.

FACT: Glaciers have been receding and growing cyclically for hundreds of
years. Recent glacier melting is a consequence of coming out of the very cool
period of the Little Ice Age. Ice shelves have been breaking off for centuries.
Scientists know of at least 33 periods of glaciers growing and then retreating.
It’s normal. Besides, changes to glacier's extent is dependent as much on
precipitation as on temperature.

MYTH 10: The earth’s poles are warming and the polar ice caps are breaking up
and melting.

FACT: The earth is variable. The Arctic Region had warmed from 1966 to 2005,
due to cyclic events in the Pacific Ocean and soot from Asia darkening the ice,
but there has been no warming since 2005. Current temperatures are the same as
in 1943. The small Palmer Peninsula of Antarctica is getting warmer, while the
main Antarctic continent is actually cooling. Ice cap thicknesses in both
Greenland and Antarctica are increasing. North polar temperature graph here.
South polar temperature graph here. See here for sea ice extent.

Most of you are into nature topics.
I saw a cow eat a large snake today. Not only did he or she seem to enjoy
eating the snake, but acted like it was a routine thing that he or she does.
The article in the link below discusses DNA of bovines.
Some say, we are what we eat. Maybe eating snakes affects ones DNA ? It
would seem that if cows routinely eat snakes, then all other such mammals also
like to eat snakes.

http://phenomena.nationalgeographic.com/2013/01/01/how-a-quarter-of-the-cow-genome-came-from-snakes/
There is probably someway to twist this discussion and make it cave related. I
will let someone else have a go at that. There are mammals that spend a lot of
time in caves and snakes do like to hang out near cave entrances.
I bet it is not healthy for any animal to eat a venomous snake.
