As recently as September of 2013 the latest report from the Intergovernmental Panel on Climate Change (IPCC) was released to the public and it turns out to be rather embarrassing to the global warming fanatics. In 2007 IPCC claimed that the world was warming at a rate of 0.2c every ten years but the new report has revised that to a mere 0.12c per decade. The report also says that there has been no discernable increase in temperature since 1997. Furthermore, they are unable to explain why the Antarctic sea ice has increased rather than decreasing as they had predicted. IPCC has also admitted that large parts of the world were as warm as they are now for decades at a time between 950 AD and 1250 AD when there were far fewer people and no industrial pollution.

Those who are trying to sell us on the global warming theory seem to prefer to ignore the effects of the jet stream. When the jet stream followed a fairly straight path from west to east around the globe there was a minimum of mixing between the temperature zones. The result was that, in the winter months, the cold was locked in the arctic and subarctic regions where it increased day by day in the absence of the warming sun. These temperatures would go to minus 60°f. or 70°f. and cover enormous areas. The many months of this super frigid cold created snow and ice packs in the arctic regions that couldn’t be melted in one summer season. There were occasions when the jet stream would waver and permit a surge of one of these masses of super cold air to plunge down across North America, bringing disastrous results such as The Children’s Blizzard of 1888. In David Laskin’s book with that title, one can read the description, “In three minutes the front subtracted eighteen degrees from the air’s temperature. Then evening gathered in and temperatures kept dropping in the northwest gale. By morning on Friday, January 13, 1888, more than a hundred children lay dead on the Dakota-Nebraska prairie.”
In more recent times the jet stream has taken a looping path that dips all the way down into Mexico at times. This has many effects on our weather but one of the most important is the effect on the arctic climate. By repeatedly bringing arctic air down into the temperate and sub-tropic regions it prevents the arctic regions from holding back and intensifying the cold air. Because the arctic air does not have a chance to become so severely cold, the air that rides down on the jet stream is not as cold and the arctic regions do not get as cold. It follows then, that the winter buildup of ice is less and melts more quickly during the summer.
Another effect of this looping jet stream is being felt along the path of its northward sweep after it has been in the warm, southern region. When the warm, moist air that it picked up collides with the colder air in the more northern regions the result is huge amounts of precipitation in the form of rain or snow.
I am going to conclude this series by tossing out a question. What would the effects be on the world climate if the jet stream were to dip so far south that it didn’t come back? Could these deep loops be the first stages of the jet stream changing its path around this ball of earth to a pole-to-pole route rather than a west to east path? It doesn’t take much imagination to get a picture of the profound and devastating effects.
What produces the jet streams and what influences them is an unsolved mystery. Since mankind does not have these answers mankind certainly can’t claim to have any influence or control.


About authorjim

I grew up in the country near a small Montana town, I have spent a lot of time in the outdoors, working, fishing, hunting and camping but have always been interested in mechanical and electrical things. Most of my life has been spent in the use, care and repair of things mechanical, electrical an electronic. After being retired for several years, I began writing and published my first novel at the age of 79. Now, at the age of 82, I have recently published my fourth noveland it is available from me or from the pulisher or book distributor.
