Spotlight On: Sea Ice Formation
As water molecules continue to freeze onto the underside of the existing sheet , it yields ‘first year ice’, which can, in a single season in the Arctic, reach a thickness of between 1.5 and 2 metres.

“[T]he biggest issue regarding climate change is the fact that it doesn’t look like we are going to do anything about it,” wrote [David S. Sayres, a research associate involved with the project]. “If we are going to mitigate climate change and possibly stop it we, meaning humans, are going to have to make some drastic changes in the way we live and the way we get our energy; and we need to do it quickly.”
