Beware of Global Warming! World View of Global Warming-Global Warming In The Arctic and Alaska.
The Arctic is thawing very rapidly, documented by new reports from scientists and arctic natives. The Arctic Climate Impact Assessment,released in late 2004,shows changes from the ice at the North Pole to animals and human settlements. Recent reports from Greenland show glaciers moving meters per hour and rapidly thinning.The Arctic Ocean ice cap is shrinking to the smallest it has ever been in modern measurements, and even winter cold has not been refreezing it as extensively as before.
That sea ice is habitat for the polar bear. Declines in bear nutrition, birth weight and survival have moved the U.S. government (urged by three environmental groups) to propose the bear be named a species threatened with extinction.
The listing of polar bears as threatened under the U.S. endangered species act will name global warming as the main threat, a first. The reduction of the permanent Arctic sea ice by 14 percent since the 1970s is causing not only feeding and breeding difficulties, but also drownings and apparent cannibalism among bears.
The effects of climate change on other Arctic wildlife.
- Caribou give birth at specific times and locations, making them susceptible to changes in weather and vegetation.
- The tundra is now blooming slightly earlier and that it is affected by drier summers and heavier winter snow.
Other effects of global warming
The great loss of ice from the Arctic (which includes not only the polar sea ice cover but also thawing glaciers and tundra permafrost), has other major implications. One of the most important is that dark open water and tundra absorb much more solar heat than white ice and snow. This is a "feedback loop" that will make changes happen faster.
Another large effect in the Arctic is a freshening of the Arctic Ocean. In late 2002, geochemist Bruce Peterson of the Marine Biological Lab in Woods Hole, MA, and his collaborators in the US and Russia, showed that the major rivers of Siberia and Eurasia are discharging much more water now than in the 1930s.This not only meets the predictions of an effect of climate change, but indicates the scale of change affecting the Arctic.

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.
