Dr Pollack clarifies the climate change issue in calm terms: By 2030 the ice will be gone and with it the way we have been living for the last 10,000 years. Up until now, civilization thrived downstream from glaciers, bathing in and drinking from the seasonal ice melt that also fed crops and animals which in turn fed us. When the glaciers and ice caps vanish, nature turns the tap off, leaving us in a challenging situation.
More importantly, Dr Pollack also explains why ice is such an important barometer of climate change. Ice is, he explains, very close to its melting point, so the slightest change in CO2 levels triggers an immediate response from the glaciers. A warming earth triggers a rise in sea levels, as water expands when it gets warmer. A warming earth also holds less landmass moisture as the earth loses more and more water to evaporation. Millions of people will be displaced by these events and Dr Pollock makes it quite clear that we are not ready for the greatest challenge that civilization has ever faced.
