They really have no land-based predators to worry about and upon seeing a polar bear of the first time would tend to either ignore it, or might waddle up to one out of curiosity? 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.

The waters are rising around them and sea ice is flimsy � hunters can no longer drag their boats across it to the sea, leaving them stranded on the land and unable to sustain themselves and their families. Furthermore, both the Arctic and Antarctic host a range of unique ecosystem types that support many endemic invertebrate species above and below ground. The ice is depleting, though not as fast as the Arctic Ocean, and not quite the way you would think. APPLICATION ACTIVITY Select one or both of the following activities to provide students with practice applying their new knowledge.

At last count, there were 193 independent countries. In April 2006, the journal Nature published a study of estimates that foresaw a probable warming of some 5 degrees Fahrenheit should the concentration of carbon dioxide reach twice the 280-parts-per-million figure that had been the norm on Earth for at least 400,000 years. The stratospheric polar vortex is a large-scale region of air that is contained by a strong west-to-east jet stream that circles the polar region.

Charles Wilkes of the US Navy sailed along the coast of eastern Antarctica for about 2,400 km (1,500 mi), thereby definitely establishing that Antarctica was a continent, not a cluster of islands. Do you know of someone we should interview on the blog? Let us look at variation is methods of reproduction first. Threats come from the in the Army inventory to lead people to. While the receding ice pack has made this option newly feasible, the truth is that these waters are largely uncharted.

Based on data from University of Washington Polar Science Center .) Meanwhile there has been a slight increase in Antarctic sea ice volume, but only by about 5,000 km3 (insufficient to offset the Arctic decline shown in Figure 4), and most of it in a few years at the start of the record. The Walrus Mitt seals a hand inside a layer of fat to imitate walrus blubber. Today in the world that we live in there are many problems one of them is hunting whales.

Surprisingly, with all its ice and snow, Antarctica is the driest continent on Earth based on annual precipitation amounts. Often, parts of the polar vortex are pulled away from the main vortex. S.–Nordic Leaders’ Summit issued a Joint Statement which committed to working towards “the highest global standards, best international practice, and a precautionary approach, when considering new and existing commercial activities in the Arctic…” It could certainly be argued that “best international practice” with respect to HFO, is to ban its use and carriage, as has been done in the Antarctic.

Commercial fishing in the Southern Ocean only began in the 1960s, but was unregulated for the first few decades, resulting in large declines in species such as the marbled rockcod (Notothenia rossii) (1) (3). During these months, the Antarctic Ocean's upwelling zone exhibits some of the Earth's highest primary productivity. He felt they were considered to be full of “old-wives’ tales unrelated to the modern scene.” The younger members seemed to resent or at least easily dismiss the wisdom and experience of men like Byrd and Siple.45 Incidents of this growing antipathy towards Byrd actually increased during his return to Antarctica for the early stages of the Navy establishing McMurdo and Little America V stations.46 With his health failing, such inconsiderate treatment only diminished Byrd’s final visit to the continent.

It is a continent, but it has no native population or government. The seasonal pattern of moisture is due to the migration of the intertropical convergence zone. Ozone depletion over Antarctica can cause a cooling of around 6 �C in the local stratosphere. In addition, hundreds of millions of people live in areas that will become increasingly vulnerable to flooding. Each year the marker moves approximately 10 meters (30 feet) away from the Pole as the ice flows.
