Vijay Jayaraj on the State of Arctic Ice Mass and Greenland Amid Climate Change

Sea ice levels are quite important to the discussion surrounding climate change. This is because changes in sea ice volume are considered the most tangible impact of changes in global temperature levels.

Climatologists and climate change enthusiasts have thus always followed the changes in Arctic and Antarctic sea ice volume. And Greenland also has been at the center of attention, as it hosts the largest ice mass outside of the polar regions.

Of the three regions, Antarctica has seen the most consistent gain in sea ice volume (increasing in mass during the past three decades, peaking in 2014). Since this statistic does not fit well with the alarmist doomsday agenda, climate alarmists have largely ignored Antarctica and focused on the Arctic and Greenland, the decrease in Arctic sea ice volume particularly touted as proof of global warming.

Al Gore, in his 2006 climate change documentary An Inconvenient Truth, suggested that both the Arctic and Antarctic would face a huge loss of ice because of global warming. However, contrary to popular claims, measurement of sea ice in these regions actually reveals that there has been no drastic reduction in volume, and global temperature has been largely stable, not headed towards apocalypse.

Arctic Sea Ice Volume

Prior to the Modern Warm Period (18th century to the present), the world was in a deep freeze known as the Little Ice Age (LIA). According to paleoclimate records, the highest Arctic sea ice levels in 10,000 years were observed during the LIA. This 10,000-year-old climate period is also known as Holocene.

Arctic sea ice volume has been on a steady decline during the last three centuries. The primary reason for this decline is the onset of the Modern Warm Period during the 18th century.

However, although Arctic sea ice volumes began declining after the end of the LIA in the 17th century, the decrease is not unprecedented, and the volume of sea ice is nowhere near the lowest recorded levels. Rather, Arctic sea ice is still at one of its highest levels in 10,000 years.
