Scientists concerned about global warming are especially troubled by dramatic signs of climate change in Antarctica - from rapidly melting glaciers to unexplained declines in penguin populations. Records show that average winter temperatures are 10 degrees higher in parts of Antarctica today than they were 50 years ago. If that warming trend continues, say many climate experts, the vast Antarctic ice sheets could melt, causing catastrophic coastal flooding as the world`s oceans rise.
