Arctic Ice is also known as Arctic sea ice. It is ocean water that has become frozen.

It is responsible for the low temperature of the Polar Regions and ensures that global climate is always conducive. With its reflective surface that is very bright enough, it sends the sun’s hot rays back to the cosmos. However, as the arctic ice melts the dark version of the oceans meets the sun’s rays, absorbing the majority of the rays instead of reflecting it. Consequently, the oceans heat up increasing the temperature of the entire pole region.

Global warming around the polar regions is very important. The increase of the temperature at the poles regardless of how little can lead to an extended period of warming.

Effects of Global Warming

What exactly is the cause of this decline in Arctic ice over the decades? This issue has been the subject of discourse within the scientific circles.

As a result, scientists have carried out studies using statistical models and simulations. They have made inferences to the reasons behind the decline in the Arctic ice. This is because the reasons behind the decline will help make an accurate estimation of future loss. Therefore, speed up the research as the means to curtail the decline.

Human activities have been named as one of the contributing factors to the loss of arctic ice. Though not acting in isolation, scientific studies reveal that it is responsible for about 60% of the Arctic loss. Even though it is debated, certain evidence gives credence to this fact. The constant emission of greenhouse gases like carbon dioxide to the atmosphere affects the temperature of the Arctic as well as the ice. Scientists have also warned and predicted a negative aftermath that awaits the planet if this is not in check.

Another factor contributing to the Arctic ice decline is the internal climate variability. This climate variability represents natural changes that occur due to the chaotic or unpredictable system of the global climate system. Its unpredictability is seen in the fact that every year, these natural changes like changes in the atmospheric circulation have the capacity to reduce or increase the magnitude of arctic sea ice decline necessitated by anthropogenic –induced global warming.

Using statistical analyses and simulation models, Qinghua Ding and his team made significant progress as regards to this finding.  They showed how imperative natural variability arctic ice decline. As they made an estimate of its contribution, by making long-term observations of the decline of September summertime sea ice.  Also that these natural variability seen mostly as high magnitude atmospheric circulation changes could be contributing up to 60% of observed summer-time Arctic sea-ice loss since 1979.

These findings do not rule out the effect human emissions habits have on the artic but it gives insight on the extent of its contribution to this regard. A better understanding of the natural variability of the climate is still needed as it is considered the chief factor when it comes to sea ice loss.

The effects of the Arctic ice depletion are obvious even though they are quite grave. These effects are felt both by the primary arctic ecosystems, endangering the existence of living species, inhabitants of neighboring coastlines like Alaska will be forced to relocate to avoid flooding claiming lives. Other effects of global consequence include identification of new shipping routes, new fossil fuel reserves and lots of other climate impacts that might be catastrophic.

Though what stares mankind is doom from these scientific findings, hope can be preserved, not just by creating awareness which is very important but by also taking commensurate actions.
