- Title
Arctic Sea Ice Loss - A World of Trouble.

- Abstract
Arctic sea ice loss is a significant issue that has far-reaching consequences for the planet. Over the past three decades, the oldest and thickest ice has declined by 95 percent, and 70 percent of Arctic sea ice is now thin "seasonal ice" that melts quickly in the summer. This loss of sea ice has a profound impact on the climate, leading to powerful storms, disrupted agricultural seasons, and increased risk of flooding in coastal cities. The loss of Arctic sea ice is also connected to the weakening of Greenland's glaciers and the acceleration of sea-level rise. A group of scientists and engineers known as PRAG has proposed a plan to refreeze Arctic sea ice using methods such as marine cloud brightening and stratospheric aerosol injection. While there are concerns about the potential risks of geo-engineering, PRAG argues that the moral hazard is not to take action to prevent catastrophe. The loss of Arctic sea ice has already led to extreme weather events and altered the behavior of the polar jet stream, with serious implications for the entire Northern Hemisphere. Urgent action is needed to address this issue and restore Arctic sea ice before it reaches a tipping point.
