"Higher levels of water vapor in an air mass at warmer temperatures is due solely to the increased evaporation of water caused by the heat/energy. Air has no ability to hold water at any time or at any temperature. It’s the law."

Your interpretation of Dalton's law is incorrect. Warmer air does "hold more moisture". See any chart of "absolute humidity" to see the maximum amount of water vapor a given volume of air can contain. The water contained by the air is just another gas as far as Dalton's law is concerned.

The headline is totally misleading. Warm air CAN hold more moisture in a given volume than the same volume can hold at a lower temperature.... this is a simple FACT of physics. All that said, using the increased snowfall as evidence of "climate change" is ludicrous.

The NYT referenced a US government report that said more snow in the NE along with less snow or other precipitation in the SE and South would be a signature of global warming.

Alas for the report, along with more snow in the NE we also got more snow in the SE and the South!

Looks like that could be a signature for global cooling.

Warmer air holds more moisture, of course.

But saturated air at 32 degrees F holds the same amount of moisture at a given pressure, every time.

If it were warm it would rain. When it is cold, it snows.

Let's get Old School, Baby!... Psychrometric Charts!

So moisture means liquid water or gaseous water vapor ?
