Peru's glacier is vanishing (http://www.cbc.ca/technology/story/2007/02/16/science-glacier.html)

What makes this thing different is that the glaciers in tropical places like Andes and Himalayas have been overlooked as scientists concentrated more on the polar regions.

Ohio State glaciologist Lonnie Thompson and a team of scientists said they have found evidence the Qori Kalis glacier of the Quelccaya ice cap in the Peruvian Andes could lose half its mass in 12 months and could be gone five years from now.

.......

The Quelccaya ice cap covers 44 square kilometres in the Cordillera Oriental region and is the world's largest tropical ice mass. Its biggest glacier, the Qori Kalis, has receded by at least 1.1 kilometres since 1963, when the first formal measurements were taken. The rate of retreat has increased from six metres per year between 1963 and 1978 to 60 metres per year now, said Thompson.

they really need to do something about it,
why do we want to destroy our once nice and lovely planet ?

Even more evidence of global warming.

People have to understand that just because there is evidence for certain localized climate change doesn't necessarily prove the existence of anthropocentric global warming. It's beyond question that temperatures are definitely rising and have been hotter than they have been in quite a while but how much of it is human related and what are the future implications are the issues that serious skeptics are debating about.

well, i think it has a lot to do with us ppl.
all those cars dude, and airplanes ...
it's mainly because of that i think,
it would have been the same way without CO2 gasses i guess, but it would take much longer to reach the point of where it is now

I agree, humans have just speeded up the process dramitically. You only have to look at graphs which show human CO2 emmisions to see that we are responsible. How people can still argue that global warming is fake or a government ploy is beyond me.

The climate system varies through natural, internal processes and in response to variations in external "forcing" from both human and natural causes. These forcing factors include solar activity, volcanic emissions, variations in the earth's orbit (orbital forcing) and greenhouse gases. The detailed causes of the recent warming remain an active field of research, but the scientific consensus identifies greenhouse gases as the main influence.

i think it says enough
