Global warming

I'll bite----I'm sure there are links to show anything to anyone, but since
this is a leps list we will be able to ask the butterflies whether they
believe in weather extremes.

The butterflies in New Jersey line up solidly with the media, that the spring
of 2003 has been an "extreme".  The cold, wet June (wettest June since record
keeping) following an extreme winter, has resulted in extremely few
butterflies.  The numbers of some species will be very high because the late
spring has shifted their phenology so that they will be encountered on 4th of
July Counts (4JCs).   Some species may benefit from the high rainfall and
fresh vegetation proliferation.
But at present there are very few butterflies in evidence in central and
northern New Jersey.    Interestingly, in upstate NY which got less extreme
weather, butterflies report less extreme conditions.

I think Chuck is right that there have been periods in the earth's history
when the climate was warmer, and tropical veg extended into what we consider
today Arctic regions.  And this happened without human agency.

But what is at issue is the rate of change, and the superimposition of
short-term cycles onto long-term cycles.
This is not a simple issue (like most scientific issues) and therefore
sorting out wheat from chaff is a challenge.
But chaff there is in abundance.

So I support Kenn's contention and I am more impressed with the evidence
linking human activities to climate change than with the contrary evidence.
If intensive animal husbandry is a significant contributor, as New Zealand
apparently believes, then efforts to control that source have to be
consideredalong with efforts to control industrial and non-point sources.

And in the final analysis there are just too many people for a planet with a
finite carrying capacity.
