States of matter is chemistry.

So, I could take a glass of hot water, throw a few ice cubes in, and in just a few minutes, it will be nice and frosty? Is that before or after the ice cubes melt?

As long as there is an ice water mixture at equilibrium the temperature will be 32°F. No wonder you guys have trouble with climate change. You don't understand grade school life science.

The fact that there is no decimal point after my 32 indicates that the precision of the number displayed is in whole degrees (32° is not the same as 32.°)

Sure there's a reason. It's that continued warming will bring large costs. If people think the clean up in New Orleans is expensive, wait until east and west coast cities require either relocation or flood control measures comparable to what the Netherlands has undertaken. The agricultural dislocation will be large. Significant parts of the Midwest will become desert and there's not enough underground water to sustain their agricultural practices even in the current environment. We will see more tropical diseases penetrate the US at a time when those diseases have become drug resistant. The status quo will be very expensive.

Under Cap & Trade prices will go up a little because the elasticity of supply will prevent huge prices for carbon. You can cut the carbon emissions from coal-fired electricity by more than 50% by converting from coal to natural gas. Conservation efforts to reduce the consumption of electricity are even more cost effective and in many parts of the country renewable electricity is already cost competitive with fossil fuel. A study by the Bush Administration Department of Energy found no statistically significant cost difference between a business as usual approach to electricity and an effort that provided for 20% wind by 2025.

Every time we have ratcheted up environmental legislation in this country, the opponents have cried about job loss and economic collapse. It never happens. Time to stop crying wolf.

Depends on the volume of water and its TDS, its temperature, the volume of ice cubes the material the water is stored in and the room temperature. Change any of those variables and you change its equilibrium point.

You didn't specify "equilibrium". But people know that the freezing point of water is zero degrees Celsius. Just as water can be boiling at temperatures higher than 212 degrees Fahrenheit--and let's not forget, you have to adjust for atmospheric pressure as well. Denver and Miami won't have the same temperatures for boiling water.

I tend not to use complex words like "equilibrium" with people who have such limited knowledge. I tell the just to stir the ice/water mixture.

You say things like, "water can be boiling at temperatures higher than 212 degrees Fahrenheit" and then allude to the pressure difference between Denver and Miami. Perhaps you mean the opposite? There really aren't places on earth where water boils at a higher temperature than 212°F.

Are you accusing our President of yet another lie? It sure sounds like it since he did say that with Cap and Trade the price of electricity would go up drastically. Darn it, somehow warmers just can't keep their stories straight sometimes.

It can in that city under the sea.

Then you don't understand the statement.

The temperature of the water can be 220 degrees...still boiling, still turning INTO steam, but there will still be liquid water higher than 212. Have you not heard of superheated mixtures?

The temperature required to boil water in Denver is LESS than in Miami--that doesn't mean that the water cannot hold a temperature higher than the boiling point as it boils.

Speaking of big words, I'm pretty sure yours was "BOOM!"...
