Notes

Global warming has many implications for the planet, but what is the effect of this process on icebergs and the ice in the Arctic or Antarctic and to the world oceans. As you have now seen global warming has many implications for the planet, but what is the effect of this process on polar caps. At the poles, many areas are warming at a rate two or three times the global average.For example, the U.S. Environmental Protection Agency (EPA) notes that the sea level has risen 15 to 20 cm (6 to 8 inches) in the last 100 years. These higher temperatures are causing some floating icebergs to melt, but more importantly are affecting the polar-caps.he full effects of global warming on the polar caps and the cryosphere are complex and not yet fully understood. We have already seen the break-up of the Larsen and Ayles Ice Shelves and the effects extend well beyond the poles themselves, and will have dramatic global implications.The warming itself may cause further accelerated warming, or a “positive feedback” . For example, the loss of sea-ice reduces albedo and changes the ability of the ocean to absorb carbon dioxide and heat.
