Earth Science - Human Impacts - Learning Points. NASA scientists measure the size of Greenland's ice sheet at five year intervals to monitor the effects of global warming. Using a laser attached to an airplane, scientists can measure the ice to an accuracy of 10cm. Scientists have discovered that the ice sheet's size is decreasing by 100 billion tonnes every year. Earth's ice sheets control sea levels and their demise will have dramatic consequences for the future. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.\n
