Antarctic sea ice continued melting fracture lead to penguins fate into the countdown

The penguin is human most interested in one of the animals. The movie "the emperor penguin diary, let us remember those furry little guys. However, rely on the ice of life by the penguin is the impact of climate change is one of the biggest species, it is namely a temperature rise of icy shorten season, their habitat is already in thaw. ugg outlet,Although melting sea ice can provide foraging for penguin place, in the short term to penguin bring "welfare", but the melting of the ice will eventually will push the penguins of despair.

The Lloyd LuoSiHai Antarctica, cape, live more than a third of the global adelie penguins and a quarter of the emperor penguin habitats, this could be the last one of the well-preserved Marine ecosystem. ugg Belgium,The main habitat should also on the Antarctic peninsula, adelie penguins quantity in the past 30 years the sharp decrease of nearly ninety percent. They are the largest ethnic group has been destroyed. In this global average temperature is one of the fastest of the regional west Antarctica peninsula, the temperature in the past half century up six degrees Celsius, more snow buried adelie penguins each spring back nesting rock. Global warming than the Antarctic peninsula constitute of the food chain, life in the ice of plankton under large death, and to the plankton for staple of krill also failed to escape by luck, Numbers were down eighty percent. And it is the important food krill penguins.

On the other side of the LuoSiHai, is more optimistic. Here, the terrain and climate local differences, winter sea ice don't reduce the increased, adelie penguins Numbers have steadily growing, especially in Lloyd, the cape, adelie penguins ethnic every year more than a 10% increase in growth. ugg norge,"Here is the penguins heaven." Research LuoSiHai penguins for 40 years of ecologists David grace and said, "if you are a penguin, here is your dream home." Although tip fracture can make the ice of the so-called between lake, short-term for penguin provide foraging places. But in the long term, no matter the Antarctic peninsula or Ross island adelie penguins, as long as the global warming they continued the survival of ice tear out, they will have nowhere to r.

Located in the United States more than MaiKeMo observation post on the island Ross stood in the past 30 years here a temperature rise 1.5 degrees Celsius, than the global average temperatures rise by big. Observatory also found that, in the Antarctic's largest lake MaiKeMo without frozen sea work more in the valley, water temperatures in the last ten years after cold slowly began to rise. Unprecedented sea temperature will result in a large iceberg split from the shelf. In the north of Ross island than ford island, the ice on the coast of the rocks back for 30000 years to the fastest speed, of course, retreat of ice can be temporarily for adelie penguins open more to the shore of the foraging, but once the ice continued melting, Ross island of the penguins will have to go to the South Pole migration. According to research adelie penguins migration routes of the report, each year on February, namely the Antarctic summer ends, this paragraph of time the penguin group will leave breeding sites, on foot or taxi to the north to avoid the Antarctic winter night and, eventually, in open sea ice junction to stop and relax, enough to support them down to hoard to return to habitat fat, getting in winter comes before having offspring. "Emperor penguins and adelie penguins are all the same, the ice is closely related with their fate," favour the doctor says, "once the sea ice disappear, they also inevitable extinction." But, as sea ice years and years retreat, the penguins will eventually trapped in the Antarctic long night, couldn't get enough time to deal with the energy reserves in winter. Grace and pointed out that dr, adelie penguins may not be the final extinction in the disappearance of habitat, but extinction of endless night in fear and nowhere in.
