Well THAT'S why it's cold!

The weather guesser on TV said that Hudson Bay is still 50% ice covered. That's salt water folks. Freezes at 28 degrees,not 32. Geez,those poor ice caps north of there don't have a chance do they?

Where oh where has poor Al gone!!!!!!!!!!!!!! He might be in the desert southwest preaching his gospel. Poor Al soooooooo very close all the time.
Ya think he might just end it all one day?

kinda blows global warming arguments doesn't it?

They are saying it's going to be 56 here tonight and 53 Saturday night. Not good for knee high toboacco but pastures sure are love'n this.

Salt water freezes at 0 degrees, thats why its called Zero(0)degrees.

Well...No.

If your are talking Celsius then fresh water will freezes at 0.

Salt water freezes at a lower temp. There is no set temperature though as the freezing point is dependent on the salt content. The more salt the lower temp required to make ice.

"Poor" Al is now worth over 100 million. One of
the world's greatest cons.

onefarmer · Jul 17, 2009

100Mil? He can buy all kinds of carbon credits and cure global warming! Yea right.

Fresh water will freeze at 0°C or 32°F. Since sea water has salt in it a lower temperature is required to freeze it.

With average salt content of the sea and due to the fact that slow freezing salt water pushes out the salt from the water it only takes -2°C or 28°F to freeze sea water.

In fact melting sea ice that was frozen slowly is fresh enough you could drink it as fresh water.

Sorry to say it but your wrong big time. Just to prove it try this. Take an ice cube tray and fill it with water then leave 2 with no salt and take and add salt to each of the others small amount and increase as you go along. Then try to freeze it. Watch it close and you will see it takes different temps to freeze each since the more salt in the water the colder it can be before it will freeze. If that where not so the CACL in tires would freeze and it is in fact SALT water

Of course you guy's are right, but when Fahrenheit developed his temperature scale he used the freezing point on salt water as his 0 point. It must have been US salt water as your the only ones to still use that scale.

Heavy water freezes at 4 degrees C or 40 degrees F.

Heavy water also makes ice cubes that will sink to the bottom.

Huh?? Better go find Al Gore to help explain all of this.....

Well, not really again.

http://en.wikipedia.org/wiki/Fahrenheit

He based zero on a ammonium chloride brine, which is a "salt" but not sea water. I guess the brine was used since it stabilizes at a certain temperature which turned out to be 0F.

Sea water will freeze above zero. The fact that it usually doesn't has more to do with tides and the chop that prevents ice from forming.

Notice that they are changing "global warming" to "climate change" - this way they can use it for about anything! We all get to pay for it!
What a joke.

Hoss In ME · Jul 19, 2009

OK,So how come cal loaded tires up here in the hinterlands wont freeze even when 45 below?Which i have seen for 3 days in a row.{nothin started either!] Hoss

Well THAT'S why it's cold!
