Global warming....work to do

governor-general, Michael Jeffery, used an 80,000-year-old core to illustrate the importance of sustainability for this and future generations.

Antarctica consist of the largest icecap that hold the secret of past world climate and events including major volcanic activities. The coldest spot on earth recorded extreme cold of -83 degrees C. Salute to the scientists who work to understand the world climate change and work to prevent aggravation of global warming.
