I have no doubt that Ignatius Rigor, Marika Holland, Mark Serreze and the many other ice analysts are right when they see
a sustained buildup of greenhouse gases resulting in a largely open - water Arctic Ocean in late summer later in this century.
That the threat posed by the
buildup of heat - trapping
greenhouse gases in the atmosphere from human activities is sufficient to justify a concerted,
sustained effort to curb, and eventually deeply cut, such emissions.
