The Melting of the Antarctic Ice Cover and Assessing Its Change Over the Past Millennium Using Climate Models
This work covers the assessment of melting trends of the Antarctic ice cover over the last millennium. BACKGROUND Recent evidence of dramatic climate change has prompted well grounded – and not purely academic - interest in probable consequences of this phenomenon. Global climate change inevitably e...
