Human activities are altering the composition of the atmosphere, and understanding how this connects to the changes we observe – and where it might lead – is one of the most pressing questions of our time. Earth's climate has shifted before, under conditions not unlike those emerging today. If we [...] temperature at a moment in the past. Another example is the isotopic composition of boron, which reflects the pH of ancient seawater – a measure of ocean acidity

Although the Antarctic offers the constant low temperatures needed, the amount of land where the soil could permanently freeze is limited; much of it is covered in ice, which insulates the ground from the cold air, often preventing the formation of permafrost.
