Arisaema growers: 
 
&nbsp;&nbsp;&nbsp; As part of the group advising on the development of th=e new USDA
hardiness map, we have been shown a variety of dataset model maps
depicting average minimum winter temperatures changes in the US.&nbsp; Us=ing
the 2003 proposed 15-year dataset, Chicago would have moved squarely
from Zone 5 into Zone 6 due to a 15-year period of abnormally warm
winters.&nbsp; Since then, Chicago has returned to more normal winter
temperatures and will remain in Zone 5.&nbsp; Raleigh, NC has not seen
temperatures below 7 degrees F since 1996, but we will still remain in
Zone 7b due to the 30-year data set that accounts for normal short-term
temperature swings.&nbsp; USDA has now agreed to use a 30-year dataset fo=r
the upcoming map and most gardeners will find that the 30-year average
shows a very slight warming trend in most parts of the county.&nbsp; FYI,
the tundra only disappeared from Maine 10,000 years ago and as I'm sure
most of you know, the Little Ice Age only ended in 1850.&nbsp; If you hav=e a
scientific interest in global climate change, I'd highly recomend the
book

It certainly appears to me that the great majority of climate
scientists think global warming is a fact.&nbsp; I myself, not a
climatologist, think it likely that anthropogenic global warming is a
fact.&nbsp; It is not politically correct, it is a scientific hypothesis
that appears to have much to support it.&nbsp; It is a reasonable working
hypothesis.
 
 
The proof or disproof, after the fact, will come long after all of us
are dead and gone.&nbsp; Taking cheap shots at it won't change the facts,
whatever they may be.&nbsp; This is probably not the best forum in which =to
debate the question.
