How Does Sea Ice Affect Penguins

Second, the setting of the image takes place somewhere cold, which is the main area affected by global warming. The penguins are standing on a block of ice symbolizing the Arctic and the block of ice is melting. “The Science Daily reports that ice melting rates were 25 times higher than expected in localized areas of Antarctica’s largest

The Earth's rise in temperature is melting ice in its colder regions. Many animals who live in the Arctic Circle, the lands surrounding

The article I found is about the endangerment of african penguins. The african penguin is endangered, and many laws have been put into place in South Africa to protect them, mainly preventing fishing so they have a stable food supply. The article talks about how fisherman are a big cause for the penguins dying out, and how the prevention of fishing has greatly increased their population. However, despite all the efforts to protect them, it still isn't enough to get them off the endangered species list. The penguins still face many dangers like water pollution and climate changes that destroy their habitats. African penguins also had a 90% decrease in population size from the 1930’s to early 2000’s. However in the last 10 years the population

The picture shows Antarctic, the ice is usually covering all of the water but climate change caused some of the ice to melt. This is impacting living organisms because it is changing their natural habitat to something very different. If the ice melts it will flood homes and animals habitats around it.

Penguins ( family Spheniscidae, order Sphenisciformes) are a group of flightless, aquatic birds living exclusively in the Southern Hemisphere, particularly in Antarctica. Well-adapted for life in the water, these birds have countershaded white and black plumage, and their wings have evolved into flat, paddle-like flippers. They feed on squid, fish, krill and other forms of sealife. Penguins spend half of their lives in the oceans and half on land. This list contains 10 unusual facts about penguins you may not know.

My name is Zachary Rowe, I am going to talk about the global warming weather effects in Alaska and how it has affected the population of various living animal species. The number of large predators living in the southern Beaufort Sea of Alaska has decreased from 1,500 animals in 2001, to just under 900 in 2010. As the species are decreasing in numbers, they are now listed as vulnerable by the International Union for the Conservation of Nature. Another problem in 2013, a report by the National Oceanic and Atmospheric Administration have seen a decline in reindeer inside Alaskan boundaries. These aren't the only species whose populations has

Kathy Conlan is an expert in understanding the weird and wonderful world of marine creatures that live deep under the Arctic ice. She specializes in marine benthic biology and amphipod systematics. Kathy studies how human and natural changes affect marine life in the Arctic and Antarctic, the effects of pollution on marine life as well as global warming. She is past chief officer for Life Sciences in the Scientific Committee on Antarctic Research (SCAR) and is a judge for SCAR’s Martha T. Muse Prize for Science and policy in Antarctica, represents Canada for the Canadian Committee on Antarctic Research, taught at Huntsman Marine Science Centre and Students On Ice, mentors university students and gives speaches and “Show and tells” at the museum.

“Penguin responses to climate change in the Southern Ocean” by Jaume Forcada and Philip N. Trathan (2009) was a study conducted to analyze and predict the migrating patterns of different species of penguins due to changes in climate. (p. 1618) Also, Forcada and Trathan investigate whether or not certain species of penguins possess phenotypic plasticity (the ability of an organism to change its phenotype in response to changes in the environment) (p. 1618).

Penguins lives in north pole. penguin eats fish, ray fish, squid, cod, krill and shrimp. They live for 10 years to 25 years. Penguins huddle up to keep warm because to protect them. A penguin is a bird but it cant fly. Baby penguins are born with out feathers. Penguins dive 50 to 60 feet to catch their food. when baby penguins are about 4 weeks old they huddle up to keep warm.

Emperor penguins (Aptenodytes forsteri) in the Antarctic are fascinating flightless birds that are able to withstand incredibly harsh environments, where wind chills can reach to -76°F. Even though these penguins are able to survive the freezing temperatures, their breeding success and mortality rates are based primarily on the sea ice concentration (SIC) and sea ice extent (SIE) throughout the seasons. Sea ice concentration is a variable for climate scientists and nautical navigators to find the area of sea ice compared to the total at a given point in the ocean, whereas sea ice extent refers to a region as “ice-covered” or “not ice-covered.” During the late 1970s, there was an elongated atypical warm period with reduced

The Ted Talk video “Pay Attention to Penguins” shows one example of a change that can affect populations. Global warming affected the penguin’s ecosystem by melting the ice caps and killing the penguins. Global warming caused by humans has several negative impacts such as melting ice caps, reducing land used for breeding, and decreasing food supplies for penguins. The melted ice caps will raise sea level which will make no land for mating and laying eggs. The food levels will diminish like squid, krill and fish which will affect the survival of the penguins. Another way to interpret the change is that

When the freezing point for water is 32 degrees fahrenheit (0 degrees celsius) what happens to life beneath the ocean when temperatures plummet in Antarctica? There has been recent discoveries of antifreeze proteins in Antarctic fish. Dr. Arthur DeVries was the first to discover such proteins, in the 1960s, and describe how they bind in the blood of fish to ice crystals and prevent the fish from being frozen.

The increasing global temperatures have caused many problems in Arctic ecosystems. The increasing warmth has caused ice caps to melt, and permafrost to thaw, causing shifts in the ecosystems around them. 1According to Harris (2005) “Permafrost is soil, rock or sediment that is frozen for more than two consecutive years. In areas not overlain by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the "active layer".” (p. 17). While the melting of ice may not seem like a big issue at first glance, its effects are truly catastrophic. Many professionals in this field, such as Houghton (2009) have said 2“Warming is expected to be strongest in the Arctic, with the continuing retreat of

When walrus hunt for food they dive in the water and find food, once they are done they return to the surface ice to lay on and rest in between their hunts. When the summer ice melts, the walrus swim to the shore for rest. As the walrus come to shore they meet each other in large groups called haul outs. Haul outs are group of walrus that gather on land due to increased receding ice. Sea ice has been receding at a fast rate and are causing more and more haul outs. These haul outs are very dangerous to the walrus because they are easily spooked from humans, cars, and other animals. When spooked, they run to the water for safety and trample other walrus on the way, giving the calves no way of survival.

The world warmed by about 0.7°C in the 20th century. Every year in this century has been warmer than all but one in the last century (1998). If carbon-dioxide levels were magically to stabilize where they are now (almost 390 parts per million, 40% more than before the industrial revolution) the world would probably warm by a further half a degree or so as the ocean, which is slow to change its temperature, caught up. But CO2 levels continue to rise. All this affect the ice pack in the Arctic. As temperature rises, ice melts. This causes many problems.
