Record-Low 2016 Antarctic Sea Ice Due to 'Perfect Storm' of Tropical, Polar Conditions
Antarctica is known for its vast expanse of sea ice that surrounds the continent. However, in 2016, the sea ice extent reached a record low. Scientists have been studying the reasons behind this phenomenon and have found that it was caused by a 'perfect storm' of tropical and polar conditions. In this article, we will delve deeper into the causes and effects of this record-low sea ice extent.
Introduction
The Antarctic sea ice extent is an important indicator of the health of our planet. It plays a crucial role in regulating global climate and ocean currents. The record-low sea ice extent in 2016 has raised concerns among scientists and policymakers alike. In this article, we will explore the reasons behind this phenomenon and its potential impact on our planet.
What is Sea Ice Extent?
Sea ice extent refers to the area covered by sea ice in a given region. It is measured using satellite data and is an important indicator of climate change. The Antarctic sea ice extent is one of the largest in the world, covering an area of over 20 million square kilometers during winter.
The 'Perfect Storm' of Tropical and Polar Conditions
Scientists have found that the record-low sea ice extent in 2016 was caused by a 'perfect storm' of tropical and polar conditions. The El Niño event in 2015-16 led to warmer ocean temperatures in the tropics, which in turn led to increased rainfall over Antarctica. This rainfall created a layer of fresh water on top of the ocean, which prevented the formation of sea ice.
At the same time, there were also changes in atmospheric circulation patterns over Antarctica. These changes led to warmer air temperatures over the continent, which further inhibited sea ice formation. The combination of these factors resulted in a record-low sea ice extent in 2016.
Impact on the Environment
The record-low sea ice extent in 2016 has significant implications for the environment. Sea ice plays a crucial role in regulating global climate and ocean currents. It reflects sunlight back into space, which helps to cool the planet. It also helps to regulate ocean currents by creating a barrier between the ocean and atmosphere.
The loss of sea ice can lead to a positive feedback loop, where warmer temperatures lead to less sea ice, which in turn leads to even warmer temperatures. This can have a cascading effect on the environment, leading to changes in weather patterns, sea level rise, and loss of habitat for marine animals.
Conclusion
The record-low sea ice extent in 2016 was caused by a 'perfect storm' of tropical and polar conditions. The El Niño event in 2015-16 led to warmer ocean temperatures in the tropics, which inhibited sea ice formation over Antarctica. At the same time, changes in atmospheric circulation patterns over Antarctica led to warmer air temperatures over the continent, further inhibiting sea ice formation.
The loss of sea ice has significant implications for the environment, including changes in weather patterns, sea level rise, and loss of habitat for marine animals. It is important that we continue to study this phenomenon and take action to mitigate its impact on our planet.
