So far we simply have not
been prepared to accept the revolutionary implications of our own
findings, and even when we do we are reluctant to voice such thoughts
openly … many are ultimately choosing to censor their own
research.

Destructive children
One number in particular
always stands out for me. That number is 0.00004. It represents the
time we humans have existed on our planet compared to Earth's total
age. Earth is 4.543 billion years old.
Modern humans have been
around for approximately 200,000 years. Perhaps 6 or 7 million years
ago our distant ancestors, possibly in what is present day Chad, and
the chimpanzee separated from our common ancestor Sahelanthropus
Tchandensis (see “Remembering uncle sah,” May 7,2013).
Only 92 elements make up ALL
of life on this planet. We humans today are quite likely breathing
the same air that the dinosaurs breathed 100 million years ago.
Scientists believe, in a general sense, that any given species of
plant and animal, vertebrate or invertebrate on average lasts around
10 million years. We Homo sapiens (sapiens) are animal vertebrates.
How long do you think humankind will manage to hang on? How much
misery and destruction to all life are we capable of leaving in our
wake?
Brief Explanation of
Weather and Climate
The numbers but which ones
The number of importance at
the moment for government policy makers and climate scientist is 2
degrees Celsius.
While it may be of more
significance politically than scientifically, it is a serious marker
that the international community has set as a temperature standard in
an attempt to avoid a global warming disaster, which in the worst
case scenario could conceivably result in human extinction, possibly
sooner than what was previously imagined. The objective is to keep
global warming increases under 2 degrees Celsius. (A temperature of 2
degrees Celsius is 35.6 degrees Fahrenheit).
Several years ago the number
400 ppm was well known to policy makers and climate scientists. It
represented parts per million of carbon dioxide in the atmosphere. The objective was to keep CO2 emissions in the atmosphere under 400
ppm.
The last monitoring station
that crossed the threshold occurred in the Antarctic on May 23 of
this year. What happens in Beijing, New York or Paris doesn't stay
there. This is the first time in 4 million years that carbon
emissions have risen above 400 ppm and remained there.
Since the beginning of the
Neolithic era, which began some 10,000 years ago global temperatures
fluctuated only about 1 degree Celsius. This is the period when human
civilization got underway, beginning with human settlements,
agriculture and what we call culture. We are now moving into the
unknown. Since the 1800s we have warmed 1 degree Celsius.
All the truth and only the
truth so help me....
Kevin Anderson, a respected
climate scientist, believes many scientists are indulging in a form
of self-censorship; in other words, they are producing reports that
are “politically” acceptable, because the reality may be far
worse than government policy makers, corporations and the public want
to hear at the present time.
The first video clip is a
short interview with Anderson at the climate talks in Paris in
December 2015 and the second video is a lecture that Anderson gave in
September 2015. It is very much about the numbers and the possible
consequences.

change and protest votes

Thanks for that about climate change, Walt. I will use Mr. Anderson's presentation as today's opening theme and see where it takes me. Reconciling the making of luxury metal objects for those with more money than sense, which is my current work, is very hard to make sense of given this climate change reality. Hard to think of how to find a better way to support my daughter through college, though. In another year I might retire to growing flowers for fun and whatever - at 75 years old. Best to you & thanks for message. Howard
