NASA to Discuss Conditions on and Surrounding the Sun
| Quote From Source: | NASA will hold a media teleconference Tuesday, Sept. 23, at 12:30 p.m. EDT, to discuss data from the joint NASA and European Space Agency Ulysses mission that reveals the sun's solar wind is at a 50-year low. The sun's current state could result in changing conditions in the solar system.
Ulysses was the first mission to survey the space environment above and
below the poles of the sun. The reams of data Ulysses returned have changed
forever the way scientists view our star and its effects. The venerable
spacecraft has lasted more than 17 years -- almost four times its expected
mission lifetime.

Very good story. I know NASA will try and downplay it because they have all their eggs in one basket with Hansen and they will never state a possible cooling larger than what Hansen things man will contribute to his global warming. They could say the sun would extinguish itself but the cooling wouldn't be enough to offset the effects of increased CO2 emissions.

The changes will be....cooler.
They should take the warning labels off of everything and let stupidity sort itself out.

I agree. Much cooler.
Still a very intresting story.

i just read a report that during the last ice age, the southwest US was much wetter than it is today...so heres to a full fledged ice age...minus the death and destruction. |

I'm pretty sure it doesn't work that way. With the ice age comes death and destruction. |

In your part of the country and South into New Mexico,and Aridzona, the natives were growing squash, sweet potatoes, beans, and corn for main staples,10,000 to 18,000 years ago. |

What Chris said. Full-bore iceage means billions die. I'm hoping for just cole enough long enough to shut Gore/Mann/Hansen up for ever.... |

a little OT but: I'm still in south California (I leave next weekend for Portland...woohoo!)...but some of the trees here are already losing their leaves, fruit, flowers, etc. Of course, there's no real fall colors here. The leaves just go brown right away. Kinda strange though. I didn't know leaves fell this early here.

| Quote From Source: | Data from the Ulysses spacecraft, a joint NASA-European Space Agency mission, show the sun has reduced its output of solar wind to the lowest levels since accurate readings became available. The sun's current state could reduce the natural shielding that envelops our solar system.
The sun's solar wind plasma is a stream of charged particles ejected from the sun's upper atmosphere. The solar wind interacts with every planet in our solar system. It also defines the border between our solar system and interstellar space.
In 2007, Ulysses made its third rapid scan of the solar wind and magnetic field from the sun's south to north pole. When the results were compared with observations from the previous solar cycle, the strength of the solar wind pressure and the magnetic field embedded in the solar wind were found to have decreased by 20 percent. The field strength near the spacecraft has decreased by 36 percent.
"The sun cycles between periods of great activity and lesser activity," Smith said. "Right now, we are in a period of minimal activity that has stretched on longer than anyone anticipated."

well, how bout that, just a few years before we face galactic center in 2012 and we lower our shields... sci fi story anyone? |

Laws of physics

magnetic polarity shift is a gradual thing, the strength lowers, as we approach the Galactic plane, goes neutral as we cross then build back opposite polarity, on the other side. Basic laws of electro-magnetics 101.
The thing to worry about, is that clouds with large amounts of neutral dust and gases reside along the Galactic plane. If the solar system passes thru one of these clouds with a high enough concentration it will create an interplanetary fog, that will cause the perceived solar output to drop, helping to bring on the next Ice age. |

a pole reversal is not the only problem we might see ...
the last time we crossed the 'galactic plane' was ~13k years ago,
the last time we were in this position of facing the galactic center
was ~26000 years ago, both make for very interesting google-ing.
peace,

I'm not so sure I'd worry about the galactic plane. Basically we are in it now. Unless the area is so thin that it only takes a year to cross. But I suspect it is large enough that it will take a number of years to cross and exit.

The immediate worry should be cooling. Isn't this is exactly what we think happened during the little ice age.
We can only hope this is more along the 50's-60's level of cooling and not worse.
I'm starting to wonder if this one might just end up worse than the LIA all said and told. As in, are we really seeing the start of the next Ice Age?!
I don't want to be alarmist, and realize we have no freaking idea.
Good commentary on this:

Buy long johns, and get firewood. Food might be a problem but hey nothing lasts forever anyway. This is all temporary.

The average American will be dead in an ice age. If the wheat and corn stops growing, you and I will probably die. Not to mention being under ice.
Yes, the south will be able to grow more food, but I still suspect more die than not. |

snow is forecast for Anchorage in a few days...albeit it's gonna be the slushy stuff. Although snow in late September there isn't unheard of...just not that common.

i will not die during the ice age...maybe raptured, but not die. ill be sipping on pine needle tea and eating elk burgers all day long. during the last ice age, glaciers stopped about a mile from my apartment. there is certainly plenty of food for me to live off of...plenty of freshwater. i should invest in a cow or two, maybe yaks cuz i do love me some milk...and cheese. |

If the ice sheet extent were suddenly the same as the last maximum, I'd be under miles of ice. |
