Global Freezing Coming Down From Canada
 
A massive arctic cold wave is heading for the midwest and east. It has
already hit the prairies with record cold and blizzard conditions with
three dead so far. A front of this strength can affect radio reception
so it might be worthwhile to tune through the bands for the next four
days.
Household tip: For some unknown reason, hot water pipes freeze
before cold water pipes.
A trickle of water will prevent pipes from freezing.
Thed Global warming debate will resume in July.

This arctic air has hit the left coast as well.

The deal with the hot water pipe freezing first is due to the lack of
dissolved gasses in the water. That is, the heating process takes the
dissolved gasses out of the water, which in turn makes it easier to
freeze.

Since a hot water system is under the same pressure as the cold and provided
that the hot water heater doesn't vent I'l like to know where the dissolved
gases in the hot water go?

Alas, It ain't so simple. The finest scientific minds of our time have
been unable to come up with a theory that can be proved by experiment.
Current theories include:
- evaporatve cooling
-convection
-dissolved gases
-surrounding environment

The finest scientific minds of our time fool around with experiments
for a while, find that they cannot isolate the variables, and go back
to their lucrative defense dept contracts where things go boom and life
is much simpler.
Aristotle noticed the freezing effect around 350bc but not much was
known about scientific method then and his deduction worked for him.
The modern name for the phenomena is "the Mpemba effect" after an
African student who found that he could freeze hot milk faster than
cold milk. ( to make ice cream)

For those who have way too much time on their hands Google
Why do hot water pipes freeze before cold water pipes?
You will get 1,100,000 hits.

For those with limited time an instructive article from Physics Web
"Does Hot Water Freeze First?"
can be found at:
http://physicsweb.org/articles/world/19/4/4

A scholarly article," Hot water Can Freeze Faster Than Cold?!?", can be
found at:::
http://arxiv.org/ps_cache/physics/pdf/0512/0512262.pdf

This would be a great subject for a science project or even a Phd
thesis.

The key to all of these is that there is something about both fluids,
apart from temperature, that is not equal.

If you have two identical, equal water fluids whose only difference is
temperature, I would bet good money that the cold one will freeze first
- it simply has to lose a lot less energy to get to the phase change.

I think the best experiment would be not to avoid the presence of
nucleation sites, but to make sure that each vessel has a roughly equal
load of them, guaranteeing that freezing would occur as soon as
possible for each one (just like in nature, where nucleation sites are
abundant).

Tell them to make up their minds.Back in the 1960's 1970's it was about
another ice age.Then along comes global warming and now it's global
freezing.I am getting tired of all of that global this,global
that,global maybe crap.This is the first time in this part of the year I
have ever seen my yard staying green and the grass and those weird
looking flowers in my yard are growing in my yard.Yesterday,I noticed

The higer the altitude,the thinner the air,the longer it takes to boil
water.Less oxygen in the air,the higher the altitude.At 20,000 feet
altitude,a shotgun sounds like striking a match.Five million years ago
there was about twenty percent more oxygen in the air.Where did the
oxygen go?

I recall one time when I was you we went camping overnight and each of us
brought a clear glass gallon of water. The jugs were left outside the tent
on the ground. That night we had a pretty good freeze. I was first up and
went to get take a leak and get a drink. I could see that the water hadn't
frozen. So I picked up a jug opened it and hoisted it to my mouth and to my
amazement the water froze in an instant. The other jug didn't. One was
city tap water and the other was from a well and I can't recall which was
which. I recall reporting the phenomena in grade 9 science and we found out
about supercooled liquids. A very interesting phenomena when you consider
that the jug that freezes nearly instantaneously has to give up a bunch of
latent heat. Since then I've seen that happen with beer thats been in the
freeze but its not as dramatic because they all do it and you can't see as
well, and there's many more other things in solution lke alcohol,etc.

I noticed that CBW, 990, Winnipeg, on the other side of the front at
the time, was unusually strong, leading me to wonder if weather could
be a factor in mw and sw propagation.

"''''''''''''''''''''''''''''''''''''''''''''''''' '''''''''''''''''''''''''''''''''''''''''''''''''' '''''''''''
I Googled around to see if weather affects mw and sw propagation and
came up with a few items. the most promising one is a paper by E.S.
Kazimirovsky and V.D. Kokourov:

"How weather Affects 160 m and MW Band Propagation"
from Geomagnetism and Aeronomy, vol 35, no3 12/95 p.305
It wasn't on line but it does indicate that people are studying the
matter.

Another article discussed the D Region 60 to 90 km high which absorbs
energy from a radio wave up to 7mhz including the MW. It considers it
as part of the atmosphere rather than the ionosphere. It is the decay
of the D Region that permits skip in the MW frequencies.
It is found in "FAQ Related to Propagation of Radio Waves" and is a
good primer on propagation.

Climate change is real

There will always be uncertainty in understanding a system
as complex as the world’s climate. However there is now
strong evidence that significant global warming is
occurring1. The evidence comes from direct measurements
of rising surface air temperatures and subsurface ocean
temperatures and from phenomena such as increases in
average global sea levels, retreating glaciers, and changes
to many physical and biological systems. It is likely that
most of the warming in recent decades can be attributed
to human activities (IPCC 2001)2. This warming has already
led to changes in the Earth's climate.
The existence of greenhouse gases in the atmosphere is
vital to life on Earth – in their absence average
temperatures would be about 30 centigrade degrees lower
than they are today. But human activities are now causing
atmospheric concentrations of greenhouse gases –
including carbon dioxide, methane, tropospheric ozone,
and nitrous oxide – to rise well above pre-industrial levels.
Carbon dioxide levels have increased from 280 ppm in
1750 to over 375 ppm today – higher than any previous
levels that can be reliably measured (i.e. in the last 420,000
years). Increasing greenhouse gases are causing
temperatures to rise; the Earth’s surface warmed by
approximately 0.6 centigrade degrees over the twentieth
century. The Intergovernmental Panel on Climate Change
(IPCC) projected that the average global surface
temperatures will continue to increase to between 1.4
centigrade degrees and 5.8 centigrade degrees above 1990
levels, by 2100.

Two indisputable facts:

FACT 1:

Carbon dioxide *IS* a "greenhouse gas". It is simply a physical property
of CO2 that has been known for years.

FACT 2:

Ice core samples going back 50,000 years show that the CO2 in the
atmosphere is waaay higher than it has ever been...the slope of the
curve is almost straight up.

Draw whatever conclusions you wish from the two facts above.

You don't drive a Volvo car,do you? If you do,stay away from Bulls.
Now,I am beginning to wonder why so many freaks like Volvo cars?

Yeah, and about 16,000 years or so Michigan was under a huge sheet of ice.

Never again!

That's what you think, Ace.

''Warming'' refers to the mean global temperature being higher.
Breakdown of the thermohaline circulator due to excessive fresh water
in the North Atlantic will cause much lower temperatures where the
Gulf Stream and other currents used to keep winters more moderate.

temp in the North atlantic are not going to affect Michigan more than
maine

we as human are certainly affect our climate what effects will result
is unclear

There is no ''global warming crowd''. There are people who see
what's plainly in front of their faces and there are people who
deserve to go extinct.

Climate change is real


Snip

Yes but mankinds influence on the climate is unproven. People make
assumptions about the mechanism behind the changing climate and then
forget it is an assumption. Remember the climate has, is and will always
be changing. People know as sheeple will take what is fed to them
without questioning it. Mankind created global warming is the dimmest
thing to come along since DRM.
