While the effect of human activity on the global climate is hotly debated, physical signs of environmental change are all around us. Some scientists say an increase in the rate of melting of the world's glaciers is evidence of global warming.

Argentina's Upsala Glacier was once the biggest in South America, but it is now disappearing at a rate of 200 metres per year. Other scientists say its reduction is due to complicated shifts in glacial dynamics and local geology.


The image on the left is from an 1859 etching of the Rhone glacier in Valais, Switzerland, and shows ice filling the valley. In 2001, the glacier had shrunk by some 2.5km, and its 'snout' had shifted about 450 metres higher up.


This is a section of shoreline at Cape Hatteras in North Carolina in the USA, pictured in 1999 and 2004. Rising sea levels are also expected to speed up coastal erosion.

things are going to be worst in the next 10 or 15 years and we do nothing at all to stop it!
its on our hands even some daily usual actions can harm the system but who cares?

I agree, we barely do anything about it :rolleyes:

We're really living every day like it's the final one.
