WARMING CLIMATE IS CHANGING LIFE ON GLOBAL SCALE, SAYS NEW STUDY
A vast array of physical and biological systems across the earth are
being affected by warming temperatures caused by humans, says a new
analysis of information not previously assembled all in one spot. The
effects on living things include ****earlier leafing of trees and
plants ****over many regions; movements of species to higher latitudes
and altitudes in the northern hemisphere; changes in bird migrations
in Europe, North America and Australia; and shifting of the oceans'
plankton and fish from cold- to warm-adapted communities.

Any NG members notice "earlier leafing of trees and plants"?
I realize it's a very short time scale...but...
On the Paul James gardening show this last weekend
he was talking about gardening in the cities. He
said that some cities have a growing zone as much
as one climate zone warmer. This is because of
Urban Heat Island effect (UHI).
I would be cautious about thinking of or planning
a garden depending on the supposed "global
warming" for every area of the United States or
the world. For example, there has been
significant crop loss for the wine industry this
spring in France and parts of California because
of cold snaps in the early spring.
yep, coolest darkest wet spring. No global warming here this year, but then
that is why the name was changed to climate change from global warming.
Nothing like marketing.

Maybe we should tell the EPA. hey just listed the polar bear as an
endangered species because of polar warming. Actually, glaciers should
be on the same list. Glaciers are fast disappearing which is bas news
because instead of reflecting sunlight back into space, when the glacier
is gone the sunlight (heat) gets absorbed by the planet and accelerates
You need to improve your reading material. What does disappearing
ice sheets in Greenland and Antarctica (not to mention the attendant
200' rise in ocean levels) suggest to you? Heating or cooling? Hmmm?
As I with a feeble mind looks at this stuff. The increase of heat has
caused much of the ice about to melt. The recently melted ice no longer
reflects energy back so it warms things up a bit.
Then why the cool spring?
Well the ice that melted flows into the ocean where the salt content is
lowered. No big deal but the ocean as a heat sink is reduced hence
wider shifts in temperature fluctuations.

In fact, the respected magazine Science has reviewed this Pentagon
report and the alleged scientific support for The Day After Tomorrow and
concludes that "it is highly unlikely that global warming will lead to a
widespread collapse" of the Gulf Stream, and
"it is safe to say that global warming will not lead to the onset of a
new Ice Age".
In Nature, another highly-respected scientific journal, a researcher
finds that halting the Gulf Stream would be impossible, arguing that
"the only way to produce an ocean circulation without the Gulf Stream
would be to turn off the wind system or stop the Earth's rotation, or
Now, although it is not going to kill us the day after tomorrow, global
warming certainly is a reality. It is caused at least partly by
mankind's use of fossil fuels. The effects will be predominantly adverse
- although high-latitude nations might prosper in a warmer world,
tropical countries will have to deal with more heat-days, altered
precipitation and higher sea-levels. So what is wrong with using a piece
of popular entertainment to campaign for action to save people from
that? As the Nasa research oceanographer William Patzert says: "The
science is bad, but perhaps it's an opportunity to crank up the dialogue
on our role in climate change."
It would be futile for me to try and refute the "nay-sayers" of "Global
Warming", as is common in science and nature, there is
contradictory evidence, some from erroneous measurements, some from
oddities that can happen over a 500 million year of the geological
record. Most of the quibbling comes from the use of models
as predictors of future events. Models use hundreds of presumptions
(premises) and not everyone can agree on the same presumptions.
The other argument is that science isn't science unless you can do it in
a lab and get reproducible results. Obviously modeling the spread of a
contagious disease, the effectiveness of a nuclear war head design.
or the interaction of solar radiation variations and greenhouse gas
concentrations can't be done in a lab but they can be approximated
by computer models. The vast majority of the physical scientists
believe that "Global Warming" is a fact but dither on putting
a time table to it. The warm water passage that is developing in
the Arctic, the melting of the ice sheets in Greenland and Antartica,
coupled with the dramatic decrease in size of the worlds glaciers
have many scientists on edge and they are talking of tipping points were
the heating will be come irreversible leading to hellish repercussions
as imagined by Steven Hawking
Now you may say that this is an alarmist attitude to take, but if we act
and "Global Warming" doesn't happen, then we look silly.
If we don't act, and "Global Warming" is real, which again, most
scientists believe is true, it could lead to another mass extinction,
