Vanishing Sea Ice

By Barbara Kessler

Satellite pictures of the Arctic suggest that this year’s summer melt likely will be worse than last year’s, providing a dramatic demonstration of how global warming can snowball — no pun intended.

As the ice melts back farther and farther each summer, it loses its ability to reflect heat from the earth, becoming a contributor to, as well as a victim of, global warming. In addition, as the permafrost of the Arctic regions warms, it releases stored carbon, adding to greenhouse gases, and furthering the escalation of warming temperatures, scientists say. All this bad news, unfortunately doesn’t have any quick fixes, but will continue escalating until and unless global warming is stalled or reduced.
