The size of the biggest peak in Antarctica is nearly 16,066 feet. This pattern alternately strengthens winds that blow cold air away from Antarctica (toward the equator) and winds that bring warmer air from middle latitudes toward Antarctica. But I think that we are asking questions here about last-ditch efforts. The Arctic Climate Impact Assessment (ACIA) focuses on four sub-regions and considers a series of key impacts: impacts on the economy, such as changes in access to resources, and impacts on people’s lives, such as effects on traditional lifestyles or damage to infrastructure.

Scientific research indicates sea levels worldwide have been rising at a rate of 0.14 inches (3.5 millimeters) per year since the early 1990s. Not that I will let that dissuade me but. Earlier melting of sea ice has two consequences for polar bears: It shortens the feeding period at a time when recently weaned seal pups are available, and it lengthens the period the bears must fast with less stored fat.

However, life in the polar deserts of the MDVs is generally limited by water due to low temperatures, and increased temperatures may have opposite impacts elsewhere (Nielsen et al. 2012 ). To fully immerse our guests in the experience and take advantage of the many opportunities to view wildlife ashore, we utilize a fleet of inflatable Zodiac landing craft that can be deployed quickly from the back of the ship.
