Reference: Ice loss at billions of tons every year, Bangkok Post, November 23, 2009

It is reported that our carbon dioxide emissions are causing the East Antarctic ice shelf to lose 57 billion tonnes of ice per year and that if CO2 emissions are not reduced this process could raise sea levels by 5m (Ice loss at billions of tons every year, Bangkok Post, November 23, 2009). This global warming alarm is based on measurements of changes in the earth's gravitational field. These measurements are not sufficiently precise to detect a rate of ice loss of 57 billion tonnes per year. Therefore no conclusion may be drawn from these data with regard to ice loss. Climate scientists also claim that during the Eemian interglacial warm period 128,000 years ago, the world was 6C warmer than it is today and that the sea level was as much as 7m higher than it is today. They conclude from these data that Antarctic ice is more sensitive to carbon dioxide emissions "than previously thought". This conclusion is not consistent with the data. The Eemian period predates the Industrial Revolution and therefore the sea level rise must have been a natural process that occurred without human intervention. In fact, the Eemian data presented actually suggest that ice and sea level changes on our planet are more sensitive to natural causes than to carbon dioxide emissions from human activity.
