Beware of Global Warming! World View of Global Warming-Global Warming in Antarctica.
Above: Another view of the Müller Ice Shelf calving rapidly. Across the Peninsula, seven monitored ice shelves have declined by a total of about 13,500 km2 since 1974,nearly the area of the entire Connectcut! :o
Also,on the Larsen shelf (satellite view above),about 3,250 km2 of shelf in area B disintegrated in a 35-day period beginning on 31 January 2002. Geologists believe this portion of the shelf may have been stable for about 12,000 years before this year's collapse.
Above: Mile-long ice cliff of Marr Ice Piedmont, Anvers Island.
This cliff has receded about 500 meters since the mid 1960s. The cliff's previous position was to the left of the line of ice floating in the harbor and extended to the headland at the extreme upper left. The regional temperature has increased 5° C in winter over the past 50 years. This reduces seasonal icepack, disrupts growth of krill and changes conditions on penguin rookeries.

This small shelf,fed by glaciers from the Loubet Coast, has been receding recently after growing over a 400-year cooling period. Like other receding ice shelves such as the larger larsen, it may be a sensitive monitor of rising regional temperatures. The Larsen Ice Shelf lost a 1200 square mile section early in 2002. Earlier in the 1990's other huge sections of this shelf disintegrated. In 2003 Argentine glaciologists reported that the land-based glaciers exposed by the removal of those sections had surged rapidly into the ocean.
Thus, although ice shelves are floating and do not add to sea level when they melt or break up, land based glaciers released by such events definitely will add to sea level. Global Warming-its effect on life in antarctica
A colony of Adelies on Humble Island,in one of eight islets off Anvers Island where thousands of Adelies have nested for some 600 years. Over the last 25 years these Adelie colonies have declined sharply. Chinstrap penguins are moving rapidly into Adelie territory. Archaeological digs in penguin colonies indicate there probably were no chinstraps in this area until about 50 years ago, when average temperatures began to rise.
Ornithologist Bill Fraser stands on the smooth pebbly surface of a former large colony of Adelie penguins on Torgersen Island.(left)
Unlike the colony in the photo, this nesting site has been used by fewer and fewer penguins over recent years. Analyzing climate data, island topography, and breeding statistics, Fraser believes climate change caused the loss of half of its 16,000 nesting Adelies. Warming temperatures and more open water make for greater snowfall and more difficult hunting for krill, affecting nesting success.
We are wanda,sining and chunmei and WE LOVE THE EARTH:D fine.not really.
we are supposed to do a geog project on global warming and we've decided to come up with this blog. so please do look around and be enlightened of global warming and its irreversible effects.thankyou! :D
WE SAY
-Click on the fourth tree to adopt-a-tree to support and promote saving the environment. thankyou! :) SAVE THE EARTH,STOP GLOBAL WARMING TODAY!
warning: THE EARTH IS ON ITS VERGE OF EXTINCTION.
Us alone cannot change the world!
So please help save the earth by playing your part! :)) REDUCE,REUSE AND RECYCLE TODAY!
"Montreal — tens of thousands of people ignored frigid temperatures Saturday to lead a worldwide day of protest against global warming."
- Canadian Press, December 2005
"… those who are absolutely certain that the rise in temperatures is due solely to carbon dioxide have no scientific justification. It's pure guesswork."

Global warming What is Global Warming?
An increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. How Global Warming Affects us
Effects of global warming on the environment and for us are varied. It is difficult to attribute specific natural phenomena to long-term causes, but some effects of recent climate change may already be occurring. Rising sea levels, glacier retreat, Arctic shrinkage, and altered patterns of agriculture are cited as direct consequences, but predictions for secondary and regional effects include extreme weather events, an expansion of tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact. Concerns have led to political activism advocating proposals to mitigate, eliminate, or adapt to it. Is Global Warming a current threat?
Global warming is definitely a current threat that isn’t about to stop any time soon unless everyone put in the effort to save the earth. We can see the long-term effects coming in the melting of polar ice and glaciers. The earth is heating at a fast rate. The risks it possess are real. The sooner our race realize that, the sooner we can protect not only the nation; but the world. How can I as a student do my part?
Use recycled paper
Take shorter showers
Ditch the plastic
Unplug unused electronics
Buy minimally packaged goods
Mother earth!
Are you sick?
I can hear you
Cry
From the heat,
Scream
From the pain,
And groan
From the weight.
It is our fault,
The fault of us, humans.
Mother, forgive us.
It may be too late.
But we can try.
What will happen to
All the animals
And plants
Those who depend on you?
And us,
Your children.
Reduce,
Reuse,
Recycle.
The 3 Rs.
Follow these 3 rules,
And mother earth
Will always be with us.
