What the politicians won't remind us because their hands are in a lot of
pockets, is that the earth has been warming since the ice age. Global
warming is natural not man made. Swedish scientists observed the very large
ozone hole at the South Pole back around 90 years ago, long before we
started polluting the air with modern chemicals.
I strongly suspect in the next 35 to 40 years we will be worried about
global cooling again. I was listening to a scientist on the discovery
channel the other day as he was discussing the fact that the ozone hole was
at a near all time high. He was excited of this news as he explained that
the world as a whole while cutting back on the fluorocarbons for the last
couple of decades has had no effect on the hole getting any smaller. He
seem convinced that this is indeed a natural phenomenon.
NASA and National Oceanic and Atmospheric Administration (NOAA)
scientists report this year's (2006) ozone hole in the polar region of
the Southern Hemisphere has broken records for area and depth.
The ozone layer acts to protect life on Earth by blocking harmful
ultraviolet rays from the sun. The "ozone hole" is a severe depletion of
the ozone layer high above Antarctica. It is primarily caused by
human-produced compounds that release chlorine and bromine gases in the
It was first noticed by a research group from The British Antarctic
Survey in the 1970's. Joseph Farman, Brian Gardiner and Jonathan
Shanklin, are the BAS scientists who discovered the Antarctic ozone
hole. In the 1980's the first measurements of this loss were actually
documented. In 1984, when the British first reported their findings,
October ozone levels were about 35 percent lower than the average for
the 1960s. When the first measurements were taken the drop in ozone
levels in the stratosphere was so dramatic that at first the scientists
thought their instruments were faulty.
The U.S. satellite Nimbus-7 quickly confirmed the results, and the term
Antarctic ozone hole entered popular language. More recently an ozone
hole has appeared over the North Pole. The ozone hole appeared first
over the colder Antarctic because the ozone-destroying chemical process
works best in cold conditions. The Antarctic continent has colder
conditions than the Arctic, which has no landmass. As the years have
gone by the Ozone Hole has increased rapidly and is as large as the
Antarctica continent. The hole lasts for only two months, but its
timing could not be worse. Just as sunlight awakens activity in dormant
plants and animals, it also delivers a dose of harmful ultraviolet
radiation. After eight weeks, the hole leaves Antarctica, only to pass
over more populated areas, including The Falkland Islands, South Georgia
and the tip of South America. This biologically damaging, high-energy
radiation can cause skin cancer, injure eyes, harm the immune system,
and upset the fragile balance of an entire ecosystem. News about the
ozone hole that forms over Antarctica each October has spread around the
world. The ozone hole can be as big as 1.5 times larger than the United

To be sure, volcanism and other natural phenomena have some affect but
we are our own worst enemies here.

Been there, done that.
It was tried during the Nixon administration.
Failed then, will fail now.
Hell, I use up most of my day light savings setting my clocks back and
Ironically it changes so that it gets dark earlier for Halloween when the
kids are out in the streets.
DST makes Summer nights hotter and shorter.
I forget, why do we rob Peter to pay Paul?
I saw something on that, but not any details. Are we changing by two
hours in the spring, or are you just averaging out the time of
starting it earlier and ending it later?
I'm with many of you in thinking that they should just leave the damn
time alone. I work nights, and it kind of works out as daylight
stealing time for me, being active very early in the morning after
work, but inside in the evenings.
i knew an astrologer who said that day light saving time was the leading
cause of errors in astrological charts.
You know congress is overstepping it bounds when people can not get an
accurate astrological chart.
