Climate Change Facts

Posted with permission of Joe Lechtanski:

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"

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


  1. 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.
