For example, while it is clear that the Antarctic Peninsula--a thin sliver of land that juts above the Antarctic Circle...
In fact, the most basic questions--Is Antarctica as a whole warming or cooling? Is its ice cover thinning or growing?--cannot yet be answered definitively. For one thing, the continent is too big and measurement points are too few and far between. Also, scientists lack the long-term records...
TIME visited the region to see the continent close up and assess the state of science there. What we found was a forbidding and extraordinarily complex environment that is just starting to come into focus. Some highlights from our journey:
Three million years ago, the mean temperature of the earth was at least several degrees higher than today. Scientists still do not know precisely what caused the warming or how Antarctica responded. One group argues that during this time significant expanses of the White Continent were not merely ice free...
