Antarctic Sea Ice Growth a Signal of Climate Change


While the sea ice in the Arctic has been shrinking steadily over the years and the biggest loss of Arctic sea ice on record has been reported, the Antarctic sea is the complete opposite and has hit a record of 7.51 million square miles, a fact that scientists say could be a signal of man-made climate change.

Those sceptical of climate change have grabbed hold of this ice spread to argue that the planet isn’t undergoing global warming; however scientists say these sceptics are simply misinterpreting what’s happening.

Researcher Ted Maksym said, “A warming world can have complex and sometimes surprising consequences.” These scientists believe that the shifts in wind patterns and the hole in the ozone over the Antarctic, both a result of human activity, are probably causing the increase in the ice.

Ice expert and NASA chief scientist Waleed Abdalati said that while the change isn’t as substantial as what is being seen in the Arctic, this doesn’t mean that we shouldn’t be paying attention to it. The main driver behind the Antarctic ice is the wind and the changes in wind are tied to climate change from greenhouse gases. Climate change has created a system where the wind is keeping cool weather “bottled up” in Antarctica.

Scientists have created computer models which have long predicted that Antarctica would be the slowest to respond to global warming, but that doesn’t mean that it’s proof that climate change is not going happening.
