Climate change activists
like to point to 5, 10 or sometimes 20 year temperature graphs as
"evidence" of manmade climate change.
J Storr Halls of the
Foresight Institute looks at some Greenland Ice core data going back 8,000
years and comes up with some interesting graphs:
The first graph is
pretty scary in that it appears to show a dramatic "Hockey stick"
warming trend:
First, note that the
rise begins around 1850, long before the first car, truck or airplane was ever
invented.
However if you extend
the timeline of the graph back a little bit, this is what you see:
Wow, look how much
warmer it was during the well documented "Medieval warming period from 900
AD to 1100 AD, far warmer than the most dire global warming predictions for the
year 2100 predictions. But wait, there's more!
Go back even further and
you find this:
The warming periods that
occurred around the time of the birth of Christ and a thousand years
prior make the Medieval warming period look like a cool spell by comparison.

Jobs in the Energy Sector
Why are there so many jobs in
the solar industry and why does solar need government (taxpayer) subsidies to
be cost competitive?
These
figures from the May 2017 US Energy Information Administration (EIA)
"Monthly Energy Review" https://www.eia.gov/totalenergy/data/monthly/pdf/mer.pdf
and the US Energy and
Employment Report for 2106 https://energy.gov/sites/prod/files/2017/01/f34/2017%20US%20Energy%20and%20Jobs%20Report_0.pdf
US Solar industry employment
= 373.8 thousand
US Natural Gas employment =
362.2 thousand
US Coal production employment
= 160.1 thousand
Electricity production by
energy source:
Solar
=
33.75 Billion KW-HR
Natural Gas = 1,380
Billion KW-HR
Coal
= 1,280
Billion KW-HR
Dividing production my
employment yields the following production efficiencies per 1,000
employees:
Solar:
= 0.09 Billion KW-HR per 1,000 employees
Natural gas
= 3.81 Billion KW-HR per 1,000 (42.3 X more labor efficient than solar)
Coal
= 8.0 Billion KW-HR per 1,000 employees (89X more labor efficient
than solar
Are you interested in helping others? Can you handle and care for people who learn differently and have other behavioral problems? Do you want to make a difference in a young child's life? If you answered "yes" to any of these questions, then you might consider a career in special education. Below is a breakdown of the short and long-term responsibilities of a special education teacher.http://www.writingdesk.pw/
