Global warming brings early spring to Arctic: study
Mon Jun 18, 11:54 PM ET

CHICAGO (AFP) - In the upper reaches of Greenland, the Arctic spring
comes several weeks earlier than it did a decade ago, according to a
study released Monday that underscores the far-reaching impact of
global warming on the northern polar region.

Researchers discovered that plant, insect and bird life native to the
High Arctic had made dramatic seasonal cycle adjustments to the
region's earlier snow melt in the space of just 10 years.

On average, the insects, plants and birds such as the Sanderling and
the Ruddy Turnstone had moved their springtime rituals -- budding,
emerging from the ground, hatching times -- forward two weeks in the
period between 1996 and 2005.

In some cases, flowers were emerging from buds and chicks were
hatching a full 30 days sooner in 2005 than they would have in 1996 in
response to sharply increased temperatures that burned off the
winter's snow layer.

"Our study confirms what many people already think, that the seasons
are changing and it is not just one or two warm years but a strong
trend seen over a decade," said Toke Hoye, a researcher with the
National Environmental Research Institute at the University of Aarhus
in Denmark.

The trend can be traced to the region's earlier spring snow melt,
which occurs about a fortnight earlier than it did a decade ago.

This should serve as an early warning system to the rest of the planet
of the scale and pace of climate-related change, the researchers said.

While not unexpected, the rate of change is surprising, even though
Arctic temperatures are increasing at twice the global average.

Similar studies have noted much more modest changes with respect to
plants in Europe (an advancement of 2.5 days per decade) and globally
(5.1 days per decade).

"We were particularly surprised to see that the trends were so strong
when considering that the entire summer is very short in the High
Arctic -- with just three to four months from snowmelt to freeze up at
our Zackenberg study site in northeast Greenland," said Hoye, a co-
author of the study.

The study is published in the June 19th issue of Current Biology and
is based on a 10-year analysis of six plant species, 12 insect species
and three bird species in a 19 square kilometer (4,700 acre) area near
Zackenberg.

But how much global warming? And what caused it? the consensus is that
we've experienced .6 degrees C increase every 100 years since the
Little Ice Age. And that is not caused by CO2 levels changing.

Liar, liar. It is acknowledged that it is caused by CO2 levels, and
that is caused by humans.

It's acknowleged by NASA, EPA, NOAA, NAS, AAAS, AGU, Royal Society,
Alcoa, Caterpillar, BP, Duke Energy, Du Pont, GE, PG&E, etc. What's
amazing is that a handful of luddites continue to put their heads in
the sand and deny it.

And, of course, not a single evidence for that :-)
It's acknowledged, it's projected, it's predicted, it's consensus... Blah Blah...
