No need for further research, techs has single handedly proved man-made gloabal warming. All the research is in due to techs study.
You've proven GW by your one-data point study. What great use of the scientific method.
We all know how predictible weather is, thats why your're local 7 day forecast is always dead on. So naturally October 12th's weather was the same for the last millions of years; until man invented the combustion engine.
[southpark] Make love to me techs [/southpark]
In the Midwest where I live in Illinois we use to get 80-100% Humidity in the summer. This summer it has been so dry that almost nothing could grow without constantly watering it. The last few years it has gotten progressively drier. The climate has changed at least for the shortfall. That may or may not indicate global warming. It seems like if all the Ice was melting that there would be more rainfall, not less.
This statement is just a statement of fact and has nothing to do with a political agenda.
On a side note. There have been 2 Ice Ages in the past. The last being 75,000 years ago. So one thing I do know is the climate is not constant. There was this little event called the dustbowl a while back.

I see a lot more dead trees in the mountians when I hike.
I know that bark beetles are a big part of the dead tree problem, especially since they don?t let the forest go through its natural cycle with fires since there are houses that might get burned to now. I think a lot of the trees I see might be dead from pollution, if not climate, either way the problem is still man made.
Considering the cycle of warming and cooling has happened many many many times in the past. The skepticism is warranted. Imagine if something happened 1000 times in a pretty regular cycle. You add in a 3rd stimulant and it happens again. Do you believe the 3rd stimulant is to blame?
Global warming is happening, nobody can deny that. Having faith this time around out of the thousands of other warming cycles is strictly man made is something hard to believe. I am sure we have a direct input however I seriously question if it is anywhere as big as the doom and gloom crowd make it out to be. Now it has gone from fringe science to religion which makes it nearly impossible to actually discuss things. Because anybody who doesnt subscribe to the faith is a blasphemer who needs to be shouted down and shut up to make way for the religions leaders work.
Luckily scientists are always trying to prove something and thus we will over the next century refine our techniques and detwemine how much we as a species are contributing. If it is a lot then we can work on curtailing emissions. If it is nearly nothing continue doing what we do.
There is a new "Dust Bowl" in process right now.
Atlanta Metro area fed by Lake Lanier & Lake Alatoona are just about dried up:
10-15-2007 Lanier down another half-foot; talk of water rationing increases
The level of Lake Lanier dropped almost another half-foot over the weekend.
The level this morning is 1057.44, down .44 foot from Friday morning.
Meanwhile, the Corps of Engineers plans to increase the flow of water out of the lake. The Corps says downstream reservoirs are nearly depleted and need additional water for a power plant and federally protected freshwater mussels. On Friday, Governor Perdue threatened to sue the Corps unless it slows the release of water from Lanier and other Georgia reservoirs.
WATER RATIONING?
As reported earlier, in about two weeks, state Environmental Protection Division Director Carol Couch is expected to send Gov. Sonny Perdue options to tighten water restrictions.
The Atlanta-Journal Constitution reports Couch has authority to limit water use as necessary with as little as five days' notice.
The paper quotes state law as saying "In the event of a dire emergency, only water for domestic and personal uses, for drinking, cooking, washing, sanitary purposes and all health related activities will be permitted. Farm uses will be given second priority; however, all other usages will be established by the Director."
This isn't unusual, imho. Same thing happen at Lake Travis, near Austin, TX. But there was record rainfall this year and it went from 40 ft low to 20 ft high.
The difference is the Army Corp is letting more water out of Lanier than coming in.
Interesting situation.
It's 100% Political with real lives on the line.
I'm sure there is a Republican Vs Democrat angle behind it.
This is worth repeating because it's really the only useful response in the thread. Leaves turning is a function of the length of daylight. Not Al Gore's current level of popularity/notoriety.
Lake Travis is the same type of a lake, it feeds water into other water sources so they can remain constant level, regardless if its lake level is low or not. More water was leaving than was coming into it. Now my point is that because Lake Lanier is in that situation doesn't mean we have an environmental disaster in our midst.
I do support a greener earth. Although its not my #1 priority.
Big conundrum.
Those pesky scientists think atmospheric pollution is masking the effects of man-made CO2/methane on climate change and that substantially reducing air pollution will further accelerate climate change.
Actually temperature, humidity and sunlight effect the tree and abscission, which cuts the flow of water to the leaf and prepares the tree for winter.
And if it's as dry in Vermont as it is around here(western North Carolina), brown seems to be the predominant color.

Please explain what "climate" actually has to do with the topic of discussion......which is Tech's observation that leaves are changing color later in the year today than 12 years ago.
You're not the only looney one Techs.
These Journalists and all the people they interview must be looney and liars too:
10-20-2007 Climate change blamed for fading foliage
EAST MONTPELIER, Vt. - Every fall, Marilyn Krom tries to make a trip to Vermont to see its famously beautiful fall foliage.
This year, she noticed something different about the autumn leaves
They're duller, not as sparkly, if you know what I mean," Krom, 62, a registered nurse from Eastford, Conn., said during a recent visit. "They're less vivid."
Other "leaf peepers" are noticing, too, and some believe climate change could be the reason.
Forested hillsides usually riotous with reds, oranges and yellows have shown their colors only grudgingly in recent years, with many trees going straight from the dull green of late summer to the rust-brown of late fall with barely a stop at a brighter hue.
"It's nothing like it used to be," said University of Vermont plant biologist Tom Vogelmann, a Vermont native.
He says autumn has become too warm to elicit New England's richest colors.
According to the National Weather Service, temperatures in Burlington have run above the 30-year averages in every September and October for the past four years, save for October 2004, when they were 0.2 degrees below average.
Colors emerge on leaves in the fall, when the green chlorophyll that has dominated all spring and summer breaks down.
But in order to hasten the decline of chlorophyll, cold nights are needed.
"The leaves fall off without ever becoming orange or yellow or red. They just go from green to brown," said Barry Rock, a forestry professor at the University of New Hampshire.

I thought we were past arguing whether or not the northern hemisphere is warmer lately than previous centuries. It?s a given, and the observations therein should also be obvious.
Yet then Dave comes barging in saying we all called everyone else lairs. I do so enjoy words shoved down my throat, don?t you?

When I was a kid, the pond in my town used to freeze all winter long, and people would skate on it every weekend (and sometimes weekday evenings) now the pond rarely freezes at all in the winter. If it does, it's skatable for maybe two or three weeks.
Looking at the NWS averages, it looks to me that highs in the past 100 years are not all in the past decade or so, lots of records in the early part of the 1900's, more so showing how the temperature cycles. I don't disagree it seems warmer, but is it a natural cycle or something else?

"The understanding of anthropogenic warming and cooling influences on climate has improved since
the Third Assessment Report (TAR), leading to very high confidence that the globally averaged net
effect of human activities since 1750 has been one of warming, with a radiative forcing of +1.6 [+0.6 to
+2.4] W m-2."
"Warming of the climate system is unequivocal, as is now evident from observations of increases in
global average air and ocean temperatures, widespread melting of snow and ice, and rising global
average sea level"
"Paleoclimate information supports the interpretation that the warmth of the last half century is
unusual in at least the previous 1300 years. The last time the polar regions were significantly warmer
than present for an extended period (about 125,000 years ago), reductions in polar ice volume led to 4
to 6 metres of sea level rise."
"Most of the observed increase in globally averaged temperatures since the mid-20th century is very
likely due to the observed increase in anthropogenic greenhouse gas concentrations. This is an
advance since the TAR?s conclusion that ?most of the observed warming over the last 50 years is likely
to have been due to the increase in greenhouse gas concentrations?. Discernible human influences now
extend to other aspects of climate, including ocean warming, continental-average temperatures,
temperature extremes and wind patterns"
