  • Every time I hear this lady narrate one of your vids I start sucking my thumb and reach for teddy.

  • The US government is raising the ph of the soil (causing crop failures) by spraying heavy metals in to the atmosphere and dispersing germ warfare and biological weapons in the process (and killing 13 in Joplin MO so far). H a a r p makes a low pressure area where targeted, then the nexrad radar system emits electronic and magnetic pulses to those metallic particles to herd and direct storms and also to add strength to them.

  • Okay. Maybe the weather can be explained by La Nina and La Nada, but what explains the reason why these phenomena acted differently in 2010?

  • Last december in Ireland (where I live) there was -17 degrees celcius temperatures. Normally in december in Ireland the coldest it gets is -5 degrees celcius.

  • The Arctic Oscillation (AO) is a natural & cyclical occurrence in nature. A negative AO index is indicative of cold Arctic air pushing further south than normal. Global temps also plunged recently according to satellite measurements this winter & spring in comparison to the temperatures during the recent strong El Nino. It is the greater southern push of cold(er) air meeting humid air from the Gulf of Mexico that is responsible for the tornado outbreak (& record cold temps in England as well).

  • I understand this to be true, but there is much more to all of this weather than is mentioned. This is the effect but not the cause. I wonder if "we" are playing a part in all of this turmoil in weather. I think there is something none of us really want to know, because if we found out the truth, severe chaos would become rampid. I only know that when you tamper with mother nature and the way things are, you hurt our earth. However, all of this is our reality. There are no accidents.

  • BS. this is something much bigger that is happening!

  • "la nada" theory is KaKa

  • susan barber is an idiot. susan barber......should we also use a palm reader. GET a LIFE sue barber

    Love paula G.

  • I love these videos. The color commentary, however, needs work! Science is not mild and the voice-overs should reflect the energy of the science.

  • La Nadaaaaaaaaaaaaaa!
