Vast icy rock peaks are being melted down due to the rise of temperature above Argentina's Carlini research base in Antarctica. But scientists who have worked here for decades say the glaciers are less icy than they once were, reports AFP. For international experts stationed at the base, the frozen southern continent is a good gauge of climate change. The scientists are saying that it never used to rain in Antarctica. But now it does. Scientists monitoring conditions at the base say the average Temperature here has increased by 2.5 degree Celsius over the past century. Antarctica is a thermometer that shows how the climate is getting worse day by day. Even the local animals are also acting as a criteria of climate change.
